- The concept of "object permanence" is best associated with which developmental stage in Piaget's theory?
- Sensorimotor Stage
- Preoperational Stage
- Concrete Operational Stage
- Formal Operational Stage
Correct answer: Sensorimotor Stage
Correct answer: Sensorimotor Stage. Explanation: Object permanence, the understanding that objects continue to exist even when they cannot be observed, is a key element of the sensorimotor stage in Piaget's theory of cognitive development.
- In the context of moral development, Lawrence Kohlberg's theory is primarily focused on:
- Behavioral aspects of morality
- Emotional responses to moral dilemmas
- The reasoning process behind moral decision-making
- Cultural influences on moral values
Correct answer: The reasoning process behind moral decision-making
Correct answer: The reasoning process behind moral decision-making. Explanation: Kohlberg's theory of moral development focuses on the reasoning process that individuals use to make moral decisions, rather than their behaviors or emotions in moral situations.
- According to Carol Gilligan, traditional theories of moral development:
- Overemphasize the role of justice and underemphasize the role of care and responsibility.
- Correctly identify the universal stages of moral reasoning.
- Fail to account for cultural differences in moral reasoning.
- Overlook the importance of early childhood experiences.
Correct answer: Overemphasize the role of justice and underemphasize the role of care and responsibility.
Correct answer: Overemphasize the role of justice and underemphasize the role of care and responsibility. Explanation: Carol Gilligan criticized traditional moral development theories, particularly Kohlberg's, for overemphasizing justice and neglecting the roles of care and responsibility, especially in the context of women's moral reasoning.
- According to Jean Piaget, at which stage of cognitive development do children begin to think logically about abstract concepts and hypothetical situations?
- Sensorimotor Stage
- Preoperational Stage
- Concrete Operational Stage
- Formal Operational Stage
Correct answer: Formal Operational Stage
Correct answer: Formal Operational Stage. Explanation: In Piaget's theory, the Formal Operational Stage begins at around age 12 and is marked by the ability to think about abstract concepts and hypothetical situations.
- In developmental psychology, the term "habituation" refers to:
- The process of forming habits through reinforcement.
- The decrease in response to a stimulus after repeated presentations.
- The increase in a response due to novelty.
- The ability to remember and recall past events.
Correct answer: The decrease in response to a stimulus after repeated presentations.
Correct answer: The decrease in response to a stimulus after repeated presentations. Explanation: Habituation is a basic form of learning evident in early development, where an organism reduces its response to a repeated stimulus over time.
- Harry Harlow's research with rhesus monkeys primarily contributed to our understanding of:
- Cognitive development
- Attachment and the importance of comfort in bonding
- Moral reasoning
- Language acquisition
Correct answer: Attachment and the importance of comfort in bonding
Correct answer: Attachment and the importance of comfort in bonding. Explanation: Harry Harlow's research using rhesus monkeys demonstrated the importance of comfort in the formation of maternal bonds and attachment, challenging behaviorist theories that suggested such bonds were primarily formed through feeding.
- The phenomenon of "adolescent egocentrism" is most closely associated with which developmental theory?
- Erikson's theory of psychosocial development
- Piaget's theory of cognitive development
- Vygotsky's sociocultural theory
- Kohlberg's theory of moral development
Correct answer: Piaget's theory of cognitive development
Correct answer: Piaget's theory of cognitive development. Explanation: Adolescent egocentrism, a term introduced by David Elkind, is associated with Piaget's theory and refers to the heightened self-consciousness of adolescents.
- According to Bronfenbrenner's ecological systems theory, which system refers to the immediate environment in which a person lives and interacts?
- Microsystem
- Mesosystem
- Exosystem
- Macrosystem
Correct answer: Microsystem
Correct answer: Microsystem. Explanation: In Bronfenbrenner's ecological systems theory, the microsystem is the layer closest to the child and contains the structures with which the child has direct contact.
- In the context of adolescent development, the term "identity foreclosure" refers to:
- A period of experimentation with different roles and identities.
- The premature commitment to an identity without adequate exploration.
- A state of confusion about one's role in society.
- The process of integrating various aspects of the self into a cohesive whole.
Correct answer: The premature commitment to an identity without adequate exploration.
Correct answer: The premature commitment to an identity without adequate exploration. Explanation: Identity foreclosure, a concept in Erikson's theory of psychosocial development, occurs when an adolescent prematurely commits to an identity without adequately exploring other options.
- Which concept, introduced by Mary Ainsworth, refers to the method used to assess the quality of attachment between infants and their caregivers?
- Attachment Behavioral System
- The Strange Situation
- Secure Base Phenomenon
- Parental Investment Theory
Correct answer: The Strange Situation
Correct answer: The Strange Situation. Explanation: The Strange Situation is a procedure devised by Mary Ainsworth in the 1970s to observe attachment relationships between a caregiver and child.
- The concept of "conservation" in cognitive development, as proposed by Jean Piaget, refers to the understanding that:
- Physical properties of objects remain the same despite changes in their form or appearance.
- Natural resources must be preserved for future generations.
- Emotional states are consistent over time.
- Behaviors should be consistent with moral principles.
Correct answer: Physical properties of objects remain the same despite changes in their form or appearance.
Correct answer: Physical properties of objects remain the same despite changes in their form or appearance. Explanation: In Piaget's stages of cognitive development, conservation is the understanding that certain properties of objects, such as volume, mass, and number, remain the same despite changes in their form or appearance.
- Which of the following best describes the "zone of proximal development" in Vygotsky's theory of cognitive development?
- The range of tasks that a child can perform independently.
- The range of tasks that a child can perform with the help of a more knowledgeable other.
- The level at which a child can understand abstract concepts.
- The period during which rapid cognitive growth occurs.
Correct answer: The range of tasks that a child can perform with the help of a more knowledgeable other.
Correct answer: The range of tasks that a child can perform with the help of a more knowledgeable other. Explanation: The zone of proximal development, a key concept in Vygotsky's theory, is the difference between what a learner can do without help and what they can do with help.
- The concept of "scaffolding" in the context of child development was most prominently advocated by:
- Jean Piaget
- Lev Vygotsky
- Erik Erikson
- Lawrence Kohlberg
Correct answer: Lev Vygotsky
Correct answer: Lev Vygotsky. Explanation: Scaffolding, a concept introduced by Vygotsky, refers to the process in which a more knowledgeable other provides supports to facilitate a learner's development.
- In psychological research, which of the following best describes the concept of "demand characteristics"?
- The inherent features of an experimental setting that lead participants to guess the purpose of the study.
- The statistical characteristics of the data that require specific analytical techniques.
- The personality traits of participants that influence their responses in a study.
- The requirements set by a researcher that participants must meet to be included in the study.
Correct answer: The inherent features of an experimental setting that lead participants to guess the purpose of the study.
Correct answer: The inherent features of an experimental setting that lead participants to guess the purpose of the study. Explanation: Demand characteristics refer to subtle cues or signals in an experimental setting that communicate to the participants how they are expected to behave or respond. These cues can influence the participants' actions or responses, potentially biasing the study's results.
- In the context of psychological scales and measurements, what does 'convergent validity' refer to?
- The degree to which two different measures of the same construct produce similar results.
- The extent to which a psychological measure is distinct from other measures that it should theoretically not correlate with.
- The consistency of results when the same test is administered at two different points in time.
- The ability of a measure to predict a related but different construct.
Correct answer: The degree to which two different measures of the same construct produce similar results.
Correct answer: The degree to which two different measures of the same construct produce similar results. Explanation: Convergent validity is a type of construct validity that is established by demonstrating that a test correlates highly with other measures of the same construct. This indicates that the test is measuring what it is supposed to measure.
- In the context of experimental design in psychology, what is a 'counterbalanced design' used for?
- To ensure that all participants receive every condition of the experiment, but in a different order.
- To negate the effects of confounding variables.
- To create equivalent groups through random assignment.
- To repeat the experiment under varying conditions to check for consistency.
Correct answer: To ensure that all participants receive every condition of the experiment, but in a different order.
Correct answer: To ensure that all participants receive every condition of the experiment, but in a different order. Explanation: A counterbalanced design is used to control for the effects of order or sequence in which experimental conditions are presented. By varying the order for different participants, this design aims to average out any order effects across the entire sample.
- In the context of psychological disorders, the diathesis-stress model proposes that psychopathology results from the interaction between:
- An individual's adaptive capacities and their environmental stressors.
- Biological predispositions and psychological trauma.
- Genetic vulnerability and specific stressful life events.
- Cognitive distortions and behavioral maladaptations.
Correct answer: Genetic vulnerability and specific stressful life events.
Correct answer: Genetic vulnerability and specific stressful life events. Explanation: The diathesis-stress model suggests that psychological disorders develop due to a combination of genetic vulnerability (diathesis) and stressful environmental or life events. It posits that while an individual may have a predisposition for a disorder (due to genetics, biology, or temperament), the expression of the disorder requires exposure to certain stressors or environmental factors.
- Which of the following best describes the primary goal of cognitive-behavioral therapy (CBT) in treating mental disorders?
- To uncover unconscious conflicts and past traumas.
- To modify dysfunctional thoughts and behaviors.
- To provide unconditional positive regard and empathy.
- To explore the impact of societal and cultural factors on the individual.
Correct answer: To modify dysfunctional thoughts and behaviors.
Correct answer: To modify dysfunctional thoughts and behaviors. Explanation: Cognitive-behavioral therapy (CBT) is a type of psychotherapy that aims to modify dysfunctional emotions, thoughts, and behaviors through a goal-oriented, systematic process. It is based on the cognitive model, which asserts that thoughts, feelings, and behaviors are interconnected, and that changing negative thoughts and maladaptive behaviors can lead to changes in affect and functioning.
- During synaptic transmission, what is the immediate trigger that causes synaptic vesicles in the presynaptic terminal to release neurotransmitter into the synaptic cleft?
- The influx of calcium ions into the presynaptic terminal when the action potential arrives
- The binding of neurotransmitter to postsynaptic receptors
- The breakdown of neurotransmitter by enzymes in the cleft
- The reuptake of neurotransmitter by transporter proteins
Correct answer: The influx of calcium ions into the presynaptic terminal when the action potential arrives
The influx of calcium ions into the presynaptic terminal is the immediate trigger for vesicle release. When the action potential reaches the axon terminal, voltage-gated calcium channels open, and the resulting calcium influx causes synaptic vesicles to fuse with the membrane and release neurotransmitter by exocytosis. Receptor binding occurs afterward on the postsynaptic side, and reuptake and enzymatic breakdown are mechanisms that terminate signaling, not initiate release.
- A neuron at rest has a membrane potential of about negative 70 millivolts. Which factor is most responsible for maintaining this negative resting potential?
- The sodium-potassium pump and the membrane's selective permeability to potassium
- A continuous influx of sodium ions through open channels
- The active release of neurotransmitters from the dendrites
- The presence of the myelin sheath around the axon
Correct answer: The sodium-potassium pump and the membrane's selective permeability to potassium
The sodium-potassium pump combined with the membrane's selective permeability to potassium maintains the resting potential of roughly negative 70 millivolts. The pump moves three sodium ions out for every two potassium ions in, and at rest the membrane is far more permeable to potassium, leaving the inside relatively negative. The myelin sheath speeds conduction but does not establish the resting charge, and neurotransmitter release is unrelated to maintaining rest.
- An action potential is described as following the all-or-none principle. What does this principle mean?
- Either all neurons in a circuit fire together or none of them fire
- Once threshold is reached, the action potential fires at a fixed, full magnitude regardless of how far the stimulus exceeded threshold
- The action potential travels in both directions along the axon at once
- A neuron fires more strongly when the stimulus is stronger
Correct answer: Once threshold is reached, the action potential fires at a fixed, full magnitude regardless of how far the stimulus exceeded threshold
The all-or-none principle means that once a neuron reaches its threshold, the action potential fires at a fixed full magnitude regardless of how strongly threshold was exceeded. A stronger stimulus does not produce a larger action potential; instead it produces more frequent firing. The principle refers to a single neuron's response, not to whole circuits firing together.
- How does the myelin sheath affect the way signals travel along a neuron's axon?
- It increases the speed of neural transmission by allowing the impulse to jump between nodes of Ranvier
- It slows transmission so signals can be carefully processed
- It produces the neurotransmitters released at the synapse
- It prevents the neuron from ever reaching threshold
Correct answer: It increases the speed of neural transmission by allowing the impulse to jump between nodes of Ranvier
The myelin sheath increases the speed of neural transmission by enabling saltatory conduction, in which the action potential jumps from one node of Ranvier to the next. This fatty insulating layer reduces signal loss along the axon. Demyelinating conditions such as multiple sclerosis slow or disrupt conduction, illustrating myelin's role in fast signaling rather than neurotransmitter production.
- Acetylcholine plays many roles in the nervous system. At the neuromuscular junction, what is its primary function?
- To trigger skeletal muscle contraction
- To inhibit muscle contraction and promote relaxation
- To regulate the sleep-wake cycle in the brainstem
- To serve as the main inhibitory transmitter of the central nervous system
Correct answer: To trigger skeletal muscle contraction
At the neuromuscular junction, acetylcholine triggers skeletal muscle contraction by binding receptors on muscle fibers. Acetylcholine also contributes to attention, learning, and memory in the brain, and its loss is associated with Alzheimer's disease. It is excitatory at the muscle rather than inhibitory, distinguishing it from GABA, the main inhibitory central transmitter.
- GABA is the most widespread inhibitory neurotransmitter in the central nervous system. What is the typical effect of GABA on a postsynaptic neuron?
- It hyperpolarizes the neuron, making it less likely to fire
- It converts the neuron's signal into a hormone
- It makes the neuron more likely to fire an action potential
- It speeds reuptake of dopamine at the synapse
Correct answer: It hyperpolarizes the neuron, making it less likely to fire
GABA hyperpolarizes the postsynaptic neuron, making it less likely to reach threshold and fire. As the main inhibitory transmitter, it dampens neural excitability, and many anti-anxiety drugs and sedatives enhance GABA activity. This contrasts with glutamate, the principal excitatory transmitter that increases the likelihood of firing.
- Serotonin is implicated in many psychological processes. Which cluster of functions is serotonin most associated with?
- Voluntary muscle movement and reflexes
- Color vision and visual acuity
- Calcium-triggered vesicle fusion
- Mood, sleep, and appetite regulation
Correct answer: Mood, sleep, and appetite regulation
Serotonin is most associated with the regulation of mood, sleep, and appetite. Low serotonin activity is linked to depression, and many antidepressants act by increasing serotonin availability in the synapse. It is not primarily a motor transmitter, distinguishing its role from acetylcholine at the neuromuscular junction.
- According to the classic dopamine hypothesis of schizophrenia, the positive symptoms such as hallucinations and delusions are best explained by which neurochemical pattern?
- Reduced serotonin activity throughout the cortex
- Excessive dopamine activity in mesolimbic pathways
- Overproduction of acetylcholine at the neuromuscular junction
- A complete absence of GABA in the limbic system
Correct answer: Excessive dopamine activity in mesolimbic pathways
The dopamine hypothesis attributes the positive symptoms of schizophrenia to excessive dopamine activity in mesolimbic pathways. Support comes from antipsychotic drugs that block D2 dopamine receptors and reduce these symptoms, and from dopamine agonists that can produce psychotic-like states. The hypothesis specifically links overactive subcortical dopamine to delusions and hallucinations.
- A researcher stimulates a patient's amygdala during a procedure and the patient reports a sudden surge of fear. This is consistent with the amygdala's primary role in:
- Forming and storing semantic vocabulary
- Coordinating fine motor movements
- Processing emotions, especially fear and threat detection
- Regulating body temperature
Correct answer: Processing emotions, especially fear and threat detection
The amygdala's primary role is processing emotions, especially fear and the detection of threat. It rapidly evaluates emotional significance of stimuli and triggers physiological fear responses. Motor coordination belongs to the cerebellum, and temperature regulation belongs to the hypothalamus, so the function of the amygdala is distinct from these.
- Patient H.M. underwent removal of much of his hippocampus and was afterward unable to form new long-term memories. This case illustrates that the hippocampus is essential for:
- Forming new explicit long-term memories
- Controlling heart rate and breathing
- Retrieving childhood memories already stored before surgery
- Maintaining balance while walking
Correct answer: Forming new explicit long-term memories
The case of H.M. demonstrates that the hippocampus is essential for forming new explicit long-term memories. After surgery he retained older memories and could learn some motor skills, but could no longer convert new experiences into lasting declarative memories. This dissociation pinpoints the function of the hippocampus in memory consolidation rather than in vital functions or balance.
- The hypothalamus is a small structure with large influence over basic drives. Which set of functions does it most directly regulate?
- Conscious decision-making and planning
- Storage of procedural motor skills
- Hunger, thirst, body temperature, and hormonal control via the pituitary
- Visual processing of edges and motion
Correct answer: Hunger, thirst, body temperature, and hormonal control via the pituitary
The hypothalamus most directly regulates hunger, thirst, body temperature, and hormonal control through its links to the pituitary gland. It is a master regulator of homeostasis and many basic biological drives. Visual processing occurs in the occipital lobe and planning in the frontal lobe, so the function of the hypothalamus is distinct from those regions.
- A person suffers damage to the occipital lobe in a car accident. Which deficit is most likely to result?
- Loss of fine motor control in the hands
- Impaired visual perception
- Difficulty understanding spoken language
- Inability to feel touch on the skin
Correct answer: Impaired visual perception
Damage to the occipital lobe most likely produces impaired visual perception, because this lobe houses the primary visual cortex. Each lobe of the brain has characteristic functions: the temporal lobe supports hearing and language comprehension, the frontal lobe supports movement and planning, and the parietal lobe processes touch. Mapping these lobes of the brain and their functions is core to physiological psychology.
- Research on split-brain patients revealed that, in most right-handed people, language production is primarily controlled by which hemisphere?
- Neither hemisphere; language is subcortical
- The right hemisphere
- Both hemispheres equally
- The left hemisphere
Correct answer: The left hemisphere
In most right-handed people, language production is primarily controlled by the left hemisphere. Split-brain research showed that information presented only to the right hemisphere often could not be verbally named, because the speaking left hemisphere lacked access to it. The popular left brain versus right brain framing oversimplifies, but lateralization of language to the left is well established.
- When a sudden threat appears, the sympathetic branch of the autonomic nervous system produces which set of bodily changes?
- Increased salivation and decreased blood pressure
- Increased heart rate, dilated pupils, and release of glucose for energy
- Complete muscle paralysis and loss of consciousness
- Slowed heart rate, increased digestion, and constricted pupils
Correct answer: Increased heart rate, dilated pupils, and release of glucose for energy
The sympathetic nervous system produces increased heart rate, dilated pupils, and glucose release to fuel the fight-or-flight response. The parasympathetic branch does the opposite, slowing the heart and promoting digestion and rest. Understanding sympathetic versus parasympathetic functions clarifies how the body mobilizes for or recovers from stress.
- After a stressful event has passed, which division of the autonomic nervous system returns the body to a calm, resting state by slowing the heart and promoting digestion?
- The parasympathetic nervous system
- The peripheral sensory system
- The somatic nervous system
- The sympathetic nervous system
Correct answer: The parasympathetic nervous system
The parasympathetic nervous system returns the body to a calm resting state, slowing the heart rate and promoting digestion, often summarized as rest-and-digest. It counterbalances the sympathetic fight-or-flight response. The somatic system controls voluntary muscle movement and is not part of this automatic rest-and-recovery regulation.
- Which stage of sleep is characterized by vivid dreaming, rapid eye movements, brain activity resembling wakefulness, and near-paralysis of the skeletal muscles?
- Stage N3 slow-wave sleep
- Stage N1 light sleep
- REM sleep
- The hypnagogic transition before sleep onset
Correct answer: REM sleep
REM sleep is characterized by vivid dreaming, rapid eye movements, wake-like brain activity, and muscle atonia that prevents acting out dreams. It contrasts sharply with deep N3 slow-wave sleep, which features large slow delta waves and minimal dreaming. These distinctive REM sleep characteristics make it physiologically unique among the sleep stages.
- A sleep researcher records large, slow delta waves and finds the sleeper very difficult to awaken. Which stage of sleep is the person most likely in?
- REM sleep
- Stage N2
- Stage N3 slow-wave sleep
- Stage N1
Correct answer: Stage N3 slow-wave sleep
Large slow delta waves and difficulty awakening characterize Stage N3 slow-wave sleep, the deepest non-REM stage. Stage N1 is the brief transition into sleep, Stage N2 shows sleep spindles and K-complexes, and REM features fast wake-like activity. Recognizing the progression through these stages of sleep is standard physiological psychology content.
- The endocrine system influences behavior more slowly than the nervous system. Which statement best captures how the endocrine system communicates?
- It relies solely on neurotransmitters crossing synapses
- It releases hormones into the bloodstream that act on distant target tissues
- It functions only during sleep
- It sends rapid electrical impulses directly along nerves
Correct answer: It releases hormones into the bloodstream that act on distant target tissues
The endocrine system communicates by releasing hormones into the bloodstream, which then travel to distant target tissues and influence behavior and physiology more slowly and diffusely than neural signals. This contrasts with the fast, point-to-point electrical and synaptic signaling of the nervous system. Hormones such as cortisol and adrenaline shape stress, mood, and growth-related behavior.
- A neuron has just fired an action potential and briefly cannot fire again no matter how strong the stimulus. This period is called the:
- Resting potential
- Depolarization phase
- Threshold of excitation
- Absolute refractory period
Correct answer: Absolute refractory period
The absolute refractory period is the brief interval right after an action potential during which the neuron cannot fire again regardless of stimulus strength, because sodium channels are temporarily inactivated. This ensures action potentials travel in one direction and limits maximum firing rate. It is distinct from the resting potential, the neuron's stable charge between signals.
- Phineas Gage survived an iron rod passing through his frontal lobe but showed marked changes in personality, planning, and impulse control. This classic case is most often cited to illustrate the role of the frontal lobe in:
- Encoding new spatial memories
- Maintaining heart rate and respiration
- Processing incoming visual information
- Executive functions such as planning, judgment, and impulse control
Correct answer: Executive functions such as planning, judgment, and impulse control
The case of Phineas Gage is cited to illustrate the frontal lobe's role in executive functions such as planning, judgment, and impulse control. After his frontal injury his intellect and movement were largely intact, but his personality and self-regulation changed dramatically. This helped establish links between frontal regions and higher-order behavioral control.
- Neurotransmitters bind to receptors in a way often compared to a lock and key. What does this lock-and-key analogy describe?
- The electrical charge moving down the axon
- The specific fit between a neurotransmitter and a receptor shaped to receive it
- The breakdown of receptors after each use
- The random diffusion of any chemical to any receptor
Correct answer: The specific fit between a neurotransmitter and a receptor shaped to receive it
The lock-and-key analogy describes the specific fit between a neurotransmitter and a receptor shaped to receive it, so each transmitter activates only its matching receptors. This specificity explains why neurotransmitters and their functions are distinct and why drugs that mimic or block particular transmitters have targeted effects. Random binding would make precise signaling impossible.
- During an action potential, the rapid depolarization of the neuron's membrane is caused mainly by the movement of which ions?
- Potassium ions rushing into the cell
- Sodium ions rushing into the cell
- Calcium ions leaving the cell
- Chloride ions leaving the cell
Correct answer: Sodium ions rushing into the cell
Rapid depolarization during an action potential is caused mainly by sodium ions rushing into the cell when voltage-gated sodium channels open. This reverses the membrane's polarity from negative toward positive. Repolarization then follows as potassium ions flow out, restoring the negative resting state and defining the shape of the action potential.
- A neuroscientist measures the speed of an action potential traveling along an axon. Which feature would most increase that conduction velocity?
- A thinner, unmyelinated axon
- A heavily myelinated axon with widely spaced nodes of Ranvier
- A lower number of dendrites
- A higher concentration of neurotransmitter in the vesicles
Correct answer: A heavily myelinated axon with widely spaced nodes of Ranvier
A heavily myelinated axon with nodes of Ranvier most increases conduction velocity, because the impulse jumps rapidly between nodes in saltatory conduction. Larger axon diameter also helps, but unmyelinated thin fibers conduct slowly. Neurotransmitter concentration and dendrite number affect signaling at synapses and input, not the speed of the action potential along the axon.
- The brain's two hemispheres communicate primarily through which structure?
- The medulla
- The corpus callosum
- The cerebellum
- The pineal gland
Correct answer: The corpus callosum
The corpus callosum, a thick band of nerve fibers, is the primary pathway connecting the brain's two hemispheres and allowing them to share information. Severing it, as in split-brain surgery, disrupts communication between left and right hemispheres. The cerebellum coordinates movement and the medulla controls vital functions, so neither serves this interhemispheric role.
- In Hubel and Wiesel's research on the visual cortex, certain neurons responded best to bars of light at specific orientations. These cells are known as:
- Feature detectors
- Interneurons of the spinal cord
- Bipolar cells
- Hair cells
Correct answer: Feature detectors
Hubel and Wiesel identified feature detectors, neurons in the visual cortex that respond selectively to specific stimulus features such as the orientation of edges or bars. Their work showed that the visual system breaks scenes into elementary features early in processing. Hair cells, by contrast, are auditory receptors, not visual cortical neurons.
- A person describes recognizing a friend in a crowd partly because their expectations and prior knowledge guided how they interpreted the scene. This influence of prior knowledge on perception is an example of:
- Bottom-up processing
- Transduction
- Top-down processing
- Sensory adaptation
Correct answer: Top-down processing
Using prior knowledge and expectations to guide interpretation reflects top-down processing, in which higher-level concepts shape perception. Bottom-up processing, by contrast, builds perception from raw sensory features without prior context. The interplay of top-down versus bottom-up processing explains how both incoming data and expectations contribute to what we perceive.
- A baby assembles a perception of a novel object purely from its incoming sensory features, with no prior expectations about what it should be. This data-driven analysis is best described as:
- Perceptual constancy
- The opponent-process mechanism
- Bottom-up processing
- Top-down processing
Correct answer: Bottom-up processing
Building perception directly from incoming sensory features, with no prior expectations, is bottom-up processing, a data-driven analysis that starts at the sensory receptors. Top-down processing instead applies stored knowledge and expectations to interpret stimuli. Most real-world perception combines both, but this purely data-driven case highlights the bottom-up direction.
- Sensory receptors convert physical energy such as light or sound waves into neural signals the brain can use. This conversion process is called:
- Accommodation
- Habituation
- Transduction
- Lateralization
Correct answer: Transduction
Transduction is the process by which sensory receptors convert physical energy such as light or sound into neural signals. For example, photoreceptors in the retina transduce light into electrical activity. Without transduction the brain could not interpret environmental stimuli, making it a foundational concept in sensation and perception.
- The cones in the human retina are specialized primarily for which aspect of vision?
- Color vision and fine detail in bright light
- Detecting motion in peripheral vision only
- Regulating the size of the pupil
- Vision in very dim light
Correct answer: Color vision and fine detail in bright light
Cones are specialized primarily for color vision and fine detail in bright, well-lit conditions, and they are concentrated in the fovea. Rods, by contrast, support vision in dim light but do not detect color. This division of labor between rods and cones is central to understanding human vision in sensation and perception.
- Which neurotransmitter is the most abundant excitatory transmitter in the central nervous system and plays a key role in learning and long-term potentiation?
- GABA
- Serotonin
- Dopamine
- Glutamate
Correct answer: Glutamate
Glutamate is the most abundant excitatory neurotransmitter in the central nervous system and is central to learning and long-term potentiation, the strengthening of synapses underlying memory. GABA is its inhibitory counterpart. Distinguishing the excitatory role of glutamate from the inhibitory role of GABA is essential for understanding neurotransmitters and their functions.
- Damage to the cerebellum at the back of the brain would most likely impair a person's:
- Regulation of blood sugar
- Capacity to understand written words
- Long-term storage of factual knowledge
- Ability to coordinate smooth, balanced movements
Correct answer: Ability to coordinate smooth, balanced movements
Damage to the cerebellum most likely impairs the coordination of smooth, balanced movements, producing unsteady gait and clumsy motion. The cerebellum fine-tunes motor activity and supports balance and motor learning. Reading comprehension, factual memory, and blood sugar regulation depend on other systems, distinguishing the cerebellum's specialized motor role.
- The thalamus is often described as the brain's sensory relay station. What does this description mean?
- It generates the electrical resting potential of every neuron
- It stores all long-term memories
- It directs nearly all incoming sensory information, except smell, to the appropriate cortical areas
- It produces the hormones that control growth
Correct answer: It directs nearly all incoming sensory information, except smell, to the appropriate cortical areas
Calling the thalamus a sensory relay station means it directs nearly all incoming sensory information, except smell, to the appropriate areas of the cortex for processing. It acts as a hub routing sensory signals to their destinations. Hormone production belongs to glands, and memory storage involves the hippocampus and cortex, so the thalamus has a distinct routing role.
- During a frightening event, the adrenal glands release adrenaline (epinephrine) into the bloodstream. What is the main behavioral and physiological effect of this hormone?
- It slows neural conduction along myelinated axons
- It improves color discrimination in the retina
- It induces deep relaxation and sleep
- It heightens arousal by increasing heart rate, respiration, and energy availability
Correct answer: It heightens arousal by increasing heart rate, respiration, and energy availability
Adrenaline (epinephrine) from the adrenal glands heightens arousal by increasing heart rate, respiration, and the availability of energy, supporting the body's response to threat. As part of the endocrine system's influence on behavior, this hormonal surge complements the faster sympathetic nervous system response. It promotes mobilization, not relaxation or sleep.
- A problem-solving procedure that guarantees a correct solution if followed step by step, but may be slow, differs from a mental shortcut that produces a fast answer without guaranteeing accuracy. Which pairing correctly labels these two approaches?
- Both algorithm and heuristic guarantee a solution
- Heuristic guarantees a solution; algorithm is a fast shortcut that may err
- Both algorithm and heuristic are shortcuts that may err
- Algorithm guarantees a solution; heuristic is a fast shortcut that may err
Correct answer: Algorithm guarantees a solution; heuristic is a fast shortcut that may err
An algorithm is a systematic, exhaustive procedure (such as trying every combination of a lock) that will reach the correct answer if executed fully, though it can be slow. A heuristic trades guaranteed accuracy for speed by using rules of thumb, so it can produce errors but conserves cognitive effort. The two are distinguished by guaranteed correctness versus processing efficiency.
- A juror estimates that a defendant is likely guilty because the defendant fits her mental image of a typical criminal, ignoring base-rate information about how rare the crime actually is. Which heuristic best describes her reasoning?
- Anchoring heuristic
- Availability heuristic
- Representativeness heuristic
- Recognition heuristic
Correct answer: Representativeness heuristic
The representativeness heuristic, described by Tversky and Kahneman, leads people to judge probability by how closely something matches a prototype or stereotype, often neglecting base rates. The availability heuristic, by contrast, judges likelihood by how easily examples come to mind, not by similarity to a prototype. The juror is matching the defendant to a mental image, which is a representativeness judgment.
- Noam Chomsky proposed an innate biological mechanism that allows children to acquire grammar rapidly from limited and imperfect input. What did he call this proposed mechanism?
- Phonological loop
- Articulatory rehearsal system
- Telegraphic processor
- Language acquisition device
Correct answer: Language acquisition device
Chomsky called it the language acquisition device (LAD). He argued that the speed and uniformity of grammar acquisition, despite the poverty of the stimulus children receive, implies an innate, species-specific capacity for language. The phonological loop is a component of Baddeley's working memory model, not Chomsky's theory.
- A dog learns to salivate to a bell that has been repeatedly paired with food, whereas a rat learns to press a lever because pressing produces food pellets. What is the key conceptual difference between these two forms of learning?
- Classical conditioning associates two stimuli; operant conditioning associates behavior with its consequences
- Both are identical and the terms are interchangeable
- Classical conditioning involves voluntary behavior; operant conditioning involves reflexes
- Classical conditioning requires reinforcement schedules; operant conditioning does not
Correct answer: Classical conditioning associates two stimuli; operant conditioning associates behavior with its consequences
Classical conditioning associates two stimuli, whereas operant conditioning associates a behavior with its consequences. In Pavlov's classical conditioning, a neutral stimulus (bell) comes to elicit a reflexive response after pairing with an unconditioned stimulus (food). In Skinner's operant conditioning, voluntary behavior is shaped by its outcomes, such as reinforcement or punishment.
- A parent gives a child a sticker for finishing homework, which increases homework completion. A different parent stops a child's nagging chore reminder once the chore is done, which also increases chore completion. Which labels correctly distinguish these two operant procedures?
- The sticker is positive reinforcement; removing the reminder is negative reinforcement
- Both are punishment because they control behavior
- The sticker is punishment; removing the reminder is reinforcement
- The sticker is negative reinforcement; removing the reminder is positive reinforcement
Correct answer: The sticker is positive reinforcement; removing the reminder is negative reinforcement
Adding the sticker is positive reinforcement, and removing the aversive reminder is negative reinforcement. In both cases the behavior increases, so both are reinforcement. Positive means a stimulus is added; negative means an aversive stimulus is removed. Neither is punishment, which would decrease the behavior.
- A student studies French in the morning and Spanish in the afternoon. When trying to recall Spanish words that evening, French vocabulary keeps intruding. What memory phenomenon is occurring?
- Proactive interference
- Retroactive interference
- Decay
- Encoding failure
Correct answer: Proactive interference
This is proactive interference, in which older learning (French) disrupts the recall of newer learning (Spanish). Retroactive interference is the opposite pattern, where newly learned material disrupts memory for older material. The distinguishing cue is that the interfering information (French) was learned before the material being recalled (Spanish).
- Slot machines pay out after an unpredictable number of plays, producing high, steady rates of gambling that are very hard to extinguish. Which reinforcement schedule does this illustrate?
- Variable-interval schedule
- Fixed-ratio schedule
- Variable-ratio schedule
- Fixed-interval schedule
Correct answer: Variable-ratio schedule
This is a variable-ratio schedule, in which reinforcement follows an unpredictable number of responses. It produces the highest, steadiest response rates and is the most resistant to extinction because the next response could always be the rewarded one. A fixed-ratio schedule reinforces after a set number of responses and produces a brief post-reinforcement pause.
- Remembering the meaning of the word photosynthesis is to one memory system as remembering your own high school graduation ceremony is to another. Which pairing correctly names these two systems?
- Both are forms of procedural memory
- Photosynthesis = episodic; graduation = semantic
- Photosynthesis = procedural; graduation = semantic
- Photosynthesis = semantic; graduation = episodic
Correct answer: Photosynthesis = semantic; graduation = episodic
General knowledge of word meanings is semantic memory, and the recollection of a personally experienced event is episodic memory. Tulving distinguished these two types of explicit (declarative) long-term memory. Episodic memories are tied to a specific time and place in one's own life, whereas semantic memories are context-free facts.
- A researcher reports that participants can hold information in one store for only about 500 milliseconds before it fades, while another store holds roughly seven items for about 20 to 30 seconds without rehearsal. Which two memory stores are being described, in order?
- Short-term memory, then long-term memory
- Sensory memory, then short-term memory
- Long-term memory, then sensory memory
- Working memory, then sensory memory
Correct answer: Sensory memory, then short-term memory
The first store is sensory memory and the second is short-term memory. Sperling's partial-report work showed that iconic (visual) sensory memory holds a large amount of information briefly — on the order of about half a second. Short-term memory holds roughly seven plus or minus two items for about 20 to 30 seconds unless maintained by rehearsal.
- According to the information-processing framework, what are the three core processes that information must undergo to be successfully remembered over the long term?
- Acquisition, extinction, recovery
- Encoding, storage, retrieval
- Priming, rehearsal, recognition
- Sensation, perception, attention
Correct answer: Encoding, storage, retrieval
The three core processes are encoding, storage, and retrieval. Encoding converts information into a usable form, storage maintains it over time, and retrieval brings it back into awareness when needed. A failure at any one of these stages can result in forgetting.
- A student who reviews material in five short sessions across a week remembers it far better at test time than a classmate who crammed the same total minutes the night before. Which learning principle best explains this advantage?
- The spacing effect
- State-dependent recall
- The von Restorff effect
- The serial position effect
Correct answer: The spacing effect
This illustrates the spacing effect, the finding that learning distributed over time produces better long-term retention than the same amount of study massed together. First documented by Ebbinghaus, it is one of the most robust findings in memory research and underlies the value of distributed practice over cramming.
- In Collins and Loftus's model of semantic memory, hearing the word doctor speeds recognition of the related word nurse because activation flows along the links connecting concepts. What is this process called?
- Parallel distributed coding
- Spreading activation
- Proactive priming
- Cascaded retrieval
Correct answer: Spreading activation
This is spreading activation. In the model, concepts are represented as nodes connected by associative links, and activating one node automatically activates closely related nodes, making them easier to retrieve. This explains semantic priming, in which a related prime word speeds recognition of a target word.
- A linguist argues that speakers of a language with many distinct words for shades of blue can perceive and discriminate those shades more readily than speakers whose language has only one blue term. Which hypothesis does this claim reflect?
- The critical period hypothesis
- Chomsky's universal grammar
- The Whorfian hypothesis of linguistic relativity
- The phonemic restoration effect
Correct answer: The Whorfian hypothesis of linguistic relativity
This reflects the Whorfian hypothesis, also called linguistic relativity, which proposes that the structure and vocabulary of one's language shape or influence thought and perception. It is associated with Benjamin Lee Whorf. The strong version (language determines thought) is largely rejected, but weaker influences of language on cognition are still studied.
- In Baddeley and Hitch's working memory model, which component is specialized for temporarily storing and rehearsing verbal and acoustic information, such as a phone number repeated silently?
- The phonological loop
- The central executive
- The episodic buffer
- The visuospatial sketchpad
Correct answer: The phonological loop
The phonological loop handles verbal and acoustic information. It consists of a brief phonological store and an articulatory rehearsal process that refreshes the store by subvocal repetition. The visuospatial sketchpad, by contrast, manages visual and spatial information rather than sound.
- A car shopper sees a sticker price of 35,000 dollars first, then judges a 32,000 dollar counteroffer as a good deal, even though comparable cars sell for 28,000. Which cognitive tendency is most directly at work?
- Confirmation bias
- The framing effect
- Anchoring and adjustment
- Hindsight bias
Correct answer: Anchoring and adjustment
This is anchoring and adjustment, in which an initial value (the 35,000 dollar sticker) serves as a reference point that biases later judgments. People adjust insufficiently away from the anchor, so the 32,000 offer seems favorable relative to it rather than to the true market value of 28,000.
- After learning a phone number by grouping the ten digits into three familiar pieces such as an area code and two shorter blocks, a person recalls it far more easily. Beyond simple grouping, what does this demonstrate about the effective capacity of short-term memory?
- Chunking reduces capacity by adding processing load
- Capacity is measured in meaningful units, so chunking effectively expands it
- Capacity is unlimited once rehearsal begins
- Capacity is fixed at exactly seven digits regardless of organization
Correct answer: Capacity is measured in meaningful units, so chunking effectively expands it
Short-term memory capacity is measured in meaningful units, so chunking effectively expands it. Miller's classic estimate of about seven plus or minus two items refers to chunks, not individual elements. By packing more information into each chunk, a person can hold more raw data within the same limited number of slots.
- A chess master glances at a mid-game board for five seconds and reconstructs the positions of all pieces almost perfectly, but performs no better than a novice when the same pieces are placed randomly. What best explains the master's advantage on real game positions?
- Chunking based on familiar, meaningful patterns stored in long-term memory
- Faster sensory memory decay than novices
- Superior iconic memory resolution
- A larger raw short-term memory capacity than novices
Correct answer: Chunking based on familiar, meaningful patterns stored in long-term memory
The master relies on chunking based on familiar patterns stored in long-term memory. Expert chess players recognize meaningful configurations from experience and encode them as single chunks. When pieces are arranged randomly, those patterns are meaningless, so the expert's advantage disappears, showing the benefit comes from organized knowledge rather than greater raw capacity.
- When people recall a list of 20 words immediately after hearing it, they tend to remember the first few and the last few words best. Which part of the serial position curve is attributed to information still active in short-term memory?
- The generation effect
- The recency effect
- The von Restorff effect
- The primacy effect
Correct answer: The recency effect
The recency effect, the superior recall of the final items, is attributed to those words still being active in short-term memory at the moment of recall. The primacy effect, the superior recall of the first items, is instead attributed to those words having received more rehearsal and been transferred to long-term memory. A delay before recall eliminates the recency effect but not the primacy effect.
- A detective who already suspects one person interprets every ambiguous clue as evidence of that person's guilt while dismissing facts that point elsewhere. Which cognitive bias does this illustrate?
- Confirmation bias
- The availability heuristic
- Functional fixedness
- Belief in small numbers
Correct answer: Confirmation bias
This is confirmation bias, the tendency to seek, interpret, and remember information in ways that support one's preexisting beliefs while discounting contradictory evidence. It differs from the availability heuristic, which concerns judging frequency by ease of recall rather than selectively favoring belief-consistent evidence.
- A person needs to fasten two papers together and has a paperclip on the desk but does not think to bend it into a hook because they only conceive of it as a clip. This difficulty best illustrates which obstacle to problem solving?
- Confirmation bias
- Mental set
- The framing effect
- Functional fixedness
Correct answer: Functional fixedness
This is functional fixedness, the tendency to perceive an object only in terms of its most familiar use, which blocks recognizing alternative functions. It is related to but narrower than a general mental set; functional fixedness specifically concerns the fixed function attributed to a particular object.
- After repeatedly solving water-jar problems with one multi-step formula, participants continue using that long method even when a simpler one-step solution becomes available. Which concept best names this rigidity?
- Means-end analysis
- Insight
- Incubation
- Mental set
Correct answer: Mental set
This is a mental set, the tendency to approach new problems using strategies that worked in the past, even when they are no longer the most efficient. The classic Luchins water-jar studies demonstrated how prior successful methods can blind people to simpler solutions, a broader phenomenon than functional fixedness.
- A researcher distinguishes implicit memory for how to ride a bicycle from explicit memory for the rules of the road. The bicycle-riding skill is best classified as which kind of long-term memory?
- Procedural memory
- Semantic memory
- Episodic memory
- Prospective memory
Correct answer: Procedural memory
Knowing how to ride a bicycle is procedural memory, a form of implicit (nondeclarative) memory for skills and actions performed without conscious recollection. Semantic and episodic memory are both explicit (declarative) systems involving conscious knowledge of facts and personal events, respectively.
- A witness who later hears a false detail about a car accident from another bystander comes to incorporate that detail into their own memory of the event. Elizabeth Loftus studied this distortion under what name?
- Proactive interference
- Source amnesia
- The spacing effect
- The misinformation effect
Correct answer: The misinformation effect
This is the misinformation effect, in which exposure to misleading post-event information alters or contaminates a person's memory of the original event. Loftus's research showed how easily eyewitness memory can be reshaped by suggestion, with major implications for the reliability of testimony.
- In Tversky and Kahneman's research, telling people that a description matches a librarian rather than a farmer leads them to ignore that there are far more farmers than librarians in the population. Which error are they committing?
- Anchoring
- Loss aversion
- Base-rate neglect driven by representativeness
- The recency effect
Correct answer: Base-rate neglect driven by representativeness
They are committing base-rate neglect driven by the representativeness heuristic, judging probability by how well the description fits a stereotype while ignoring the actual frequency of each category. This shows how representativeness can override statistically relevant base-rate information.
- A patient with damage to the hippocampus can still learn new motor skills through practice but cannot form new conscious memories of facts or recent events. This dissociation best supports the distinction between which two memory systems?
- Proactive and retroactive interference
- Implicit (procedural) memory and explicit (declarative) memory
- Iconic memory and echoic memory
- Primacy and recency
Correct answer: Implicit (procedural) memory and explicit (declarative) memory
This dissociation supports the distinction between implicit (procedural) memory and explicit (declarative) memory. Hippocampal damage typically spares the ability to acquire new skills (procedural learning) while impairing the formation of new conscious memories for facts and events, indicating these systems rely on different neural substrates.
- A teacher who wants students to retain information longest should, according to memory research, favor which combination of study techniques?
- Highlighting followed by one long review
- Distributed practice combined with self-testing (retrieval practice)
- Reading aloud once without testing
- Massed cramming with rereading
Correct answer: Distributed practice combined with self-testing (retrieval practice)
Distributed practice combined with retrieval practice produces the strongest long-term retention. The spacing effect shows that study sessions separated over time beat cramming, and the testing effect shows that actively retrieving information strengthens memory more than passive rereading or highlighting.
- A person reads a list, then is interrupted before finishing a task, and later recalls the unfinished task better than completed ones. Separately, generating an answer yourself rather than reading it improves later recall. Which term names that second, generation-related advantage?
- Encoding specificity
- The generation effect
- The spacing effect
- The Zeigarnik effect
Correct answer: The generation effect
Producing information yourself rather than passively reading it improves retention through the generation effect. The Zeigarnik effect, by contrast, refers to better memory for interrupted or incomplete tasks. The question pairs them to highlight that the generation effect specifically concerns self-produced versus presented material.
- A student remembers chemistry facts much better when tested in the same classroom where they studied than in an unfamiliar room. Which memory principle best accounts for this?
- Proactive interference
- Context-dependent (encoding specificity) effects
- Functional fixedness
- The serial position effect
Correct answer: Context-dependent (encoding specificity) effects
This reflects context-dependent memory, an instance of the encoding specificity principle: retrieval improves when cues present at encoding (such as the physical environment) are also present at retrieval. The match between study and test context provides additional retrieval cues that aid recall.
- To solve a maze, a computer program could exhaustively try every path until it reaches the exit, guaranteeing success but consuming much time. A person instead generally heads toward the exit, sometimes hitting dead ends. Which describes the person's strategy?
- Trial-and-error reinforcement
- An algorithmic approach
- Functional fixedness
- A heuristic (means-end) approach
Correct answer: A heuristic (means-end) approach
The person is using a heuristic, specifically a means-end style approach that reduces the distance to the goal at each step. Unlike the exhaustive algorithm that guarantees a solution, a heuristic is faster but can lead to dead ends because it does not systematically test every possibility.
- A child who once called all four-legged animals doggie learns to apply dog only to dogs after exposure to many examples. This narrowing of an initially broad word meaning is an example of correcting which early language error?
- Telegraphic speech
- Overregularization
- Overextension
- Fast mapping
Correct answer: Overextension
The child is correcting overextension, the early tendency to apply a word too broadly to many similar referents. Overregularization is a different error, in which children apply grammatical rules too broadly (for example, saying goed instead of went). Both reflect rule-learning during language acquisition.
- In operant conditioning, a behavior that has been reinforced on a variable-ratio schedule is reintroduced after extinction and quickly returns at full strength. What does this resistance to extinction primarily demonstrate?
- That continuous reinforcement is most resistant to extinction
- That unpredictable reinforcement makes behavior persistent
- That negative reinforcement weakens behavior
- That punishment increases response rate
Correct answer: That unpredictable reinforcement makes behavior persistent
It demonstrates that unpredictable (intermittent) reinforcement makes behavior persistent and resistant to extinction. Because the organism cannot tell whether the next response will be rewarded, it keeps responding. Continuous reinforcement, by contrast, extinguishes quickly once reinforcement stops because the absence of reward is immediately obvious.
- A dieter who removes a daily latte to lose weight is most clearly using which operant principle if the goal is to make a behavior less likely, versus a manager who removes a tedious report requirement to encourage more sales calls?
- The dieter uses negative reinforcement; the manager uses positive punishment
- The dieter uses negative punishment; the manager uses negative reinforcement
- Both use positive reinforcement
- The dieter uses extinction; the manager uses punishment
Correct answer: The dieter uses negative punishment; the manager uses negative reinforcement
Removing the latte to decrease a behavior is negative punishment (removal of a desired stimulus reduces behavior), while removing the tedious report to increase sales calls is negative reinforcement (removal of an aversive stimulus increases behavior). Both involve removing a stimulus, so they are distinguished by their effect on behavior frequency.
- After studying a new list of phone contacts, a person finds it harder to recall the contacts they memorized last week. Which interference process is responsible?
- Encoding failure
- Retroactive interference
- Source confusion
- Proactive interference
Correct answer: Retroactive interference
This is retroactive interference, in which newly learned material (the new contacts) disrupts memory for previously learned material (last week's contacts). It is the mirror image of proactive interference, where older learning blocks newer learning. Here the disruption flows backward in time from new to old.
- In Tulving's encoding specificity framework, recall is best when the cues available at retrieval match those present during encoding. A diver who learns word lists underwater recalls them best underwater rather than on land. This study by Godden and Baddeley most directly supports which idea?
- Context-dependent memory
- Spreading activation
- Levels-of-processing depth
- The phonological loop's capacity
Correct answer: Context-dependent memory
The diving study supports context-dependent memory, an application of encoding specificity. Recall improved when the external environment at retrieval (underwater versus on land) matched the environment at encoding, because contextual cues from learning aided retrieval when reinstated.
- According to the levels-of-processing framework, which type of encoding should produce the most durable memory for a list of words?
- Noting whether each word rhymes with cat
- Counting the vowels in each word
- Deciding whether each word fits meaningfully into a sentence
- Judging whether each word is printed in capital letters
Correct answer: Deciding whether each word fits meaningfully into a sentence
Deciding whether a word fits meaningfully into a sentence requires semantic (deep) processing, which Craik and Lockhart's levels-of-processing framework shows yields the most durable memory. Judging letter case is shallow visual processing and rhyming is intermediate acoustic processing, both producing weaker retention than meaning-based encoding.
- A researcher primes participants with the word bread and finds they recognize the word butter faster than an unrelated word. Within a semantic network model, why does this occur?
- Butter is encoded more deeply than unrelated words
- Activation spreads from the bread node to closely linked nodes like butter
- The recency effect boosts the second word
- Bread and butter are stored in the same short-term memory slot
Correct answer: Activation spreads from the bread node to closely linked nodes like butter
Activation spreads from the bread node to closely linked nodes such as butter, pre-activating them and speeding recognition. This semantic priming is a direct prediction of the spreading activation model of semantic memory, in which related concepts are connected by strong associative links that transmit activation automatically.
- In Solomon Asch's classic line-judgment studies, participants compared a standard line to three comparison lines while seated among confederates who unanimously gave an obviously wrong answer. Across the critical trials, roughly what proportion of judgments showed conformity to the incorrect majority?
- About 37 percent
- About 99 percent
- About 5 percent
- About 75 percent
Correct answer: About 37 percent
Asch found conformity to the wrong majority on roughly 37 percent of the critical trials, even though the correct line was visually obvious. About 75 percent of participants conformed at least once, while in a control condition without group pressure people answered correctly over 99 percent of the time. The 75 percent figure describes the share of people who ever conformed, not the rate of conforming responses.
- A high school teacher is told (falsely) that certain randomly selected students are 'intellectual bloomers' poised for rapid growth. By year's end, those students show greater gains than their peers, largely because the teacher gave them more warmth, attention, and challenging work. This outcome best illustrates:
- The just-world hypothesis
- The mere exposure effect
- A self-fulfilling prophecy
- Cognitive dissonance
Correct answer: A self-fulfilling prophecy
This is a self-fulfilling prophecy, in which an initially false expectation evokes behavior that causes the expectation to come true. The teacher's belief altered how they treated the students, which in turn produced the predicted gains. This was demonstrated in Rosenthal and Jacobson's 'Pygmalion in the classroom' research.
- Three roommates are asked to pull on a rope as hard as they can, first alone and then together as a group. Each person exerts noticeably less force when pulling in the group than when pulling alone. This reduction in individual effort on a pooled task is known as:
- Social loafing
- Social facilitation
- Group polarization
- Deindividuation
Correct answer: Social loafing
This is social loafing, the tendency to exert less effort when individual contributions are pooled and not identifiable, as in a group rope-pull. It contrasts with social facilitation, where the mere presence of others boosts performance on simple, individually evaluated tasks. The difference hinges on whether one person's output can be singled out.
- In Philip Zimbardo's 1971 Stanford Prison Experiment, college students were randomly assigned to be guards or prisoners in a simulated prison. The study is most often cited to illustrate:
- The accuracy of eyewitness memory
- The power of situational forces and assigned roles to shape behavior
- The stages of moral reasoning
- The biological basis of aggression
Correct answer: The power of situational forces and assigned roles to shape behavior
The Stanford Prison Experiment is cited to show how powerfully situational forces and assigned social roles can shape behavior, as ordinary students adopted abusive or submissive conduct based on their assigned role. The study was halted early due to the guards' escalating cruelty. Critics note methodological flaws, but its standard textbook lesson concerns the influence of situation over disposition.
- A consumer who has no strong opinion about a brand sees its logo repeatedly while scrolling social media. Without ever evaluating any product claims, she later reports liking the brand more than unfamiliar ones. This increase in liking from repeated exposure alone is the:
- Halo effect
- Mere exposure effect
- Bystander effect
- Foot-in-the-door technique
Correct answer: Mere exposure effect
This is the mere exposure effect, identified by Robert Zajonc, in which repeated exposure to a stimulus increases liking for it even without conscious evaluation or new information. Familiarity itself breeds preference. It differs from persuasion techniques because no argument or request is involved.
- According to the elaboration likelihood model of persuasion, a viewer who is highly motivated and able to think carefully about an ad is most likely to be persuaded through the:
- Peripheral route, by counting the number of arguments
- Peripheral route, by reacting to the speaker's attractiveness
- Central route, by responding to background music
- Central route, by scrutinizing the quality of the arguments
Correct answer: Central route, by scrutinizing the quality of the arguments
Under the central route, persuasion depends on careful scrutiny of argument quality and occurs when the audience is both motivated and able to process the message. The peripheral route relies instead on surface cues such as a speaker's attractiveness or the sheer number of arguments, and is used when motivation or ability is low. Petty and Cacioppo developed this dual-process model.
- After waiting in a long line for a notoriously difficult and unrewarding club initiation, new members rate the club as far more enjoyable and worthwhile than members who joined with no effort. This 'effort justification' pattern is best explained by:
- Cognitive dissonance theory
- The fundamental attribution error
- The just-world hypothesis
- Social comparison theory
Correct answer: Cognitive dissonance theory
This effort-justification effect follows from cognitive dissonance theory: the discomfort of 'I suffered for something dull' is reduced by inflating the group's value. Aronson and Mills demonstrated that members who underwent a severe initiation rated their group more positively. The drive to keep beliefs and behavior consistent resolves the dissonance.
- A single person collapsing on a busy subway platform is, paradoxically, less likely to receive help than if only one or two onlookers were present. The diminished individual sense of obligation as the number of witnesses grows is termed:
- Normative conformity
- Social facilitation
- Reactance
- Diffusion of responsibility
Correct answer: Diffusion of responsibility
This is diffusion of responsibility, in which the felt obligation to act is spread across all witnesses, so each person assumes someone else will intervene. It is a key mechanism behind the bystander effect documented by Latané and Darley. More bystanders means less personal responsibility, not more help.
- Which of the following is the most accurate definition of the bystander effect?
- People help only those who belong to their own social group
- People imitate the helping behavior of the first responder
- People are less likely to help a victim when other bystanders are present than when alone
- People help more readily in groups because of shared courage
Correct answer: People are less likely to help a victim when other bystanders are present than when alone
The bystander effect is the finding that an individual is less likely to help a person in need when other bystanders are present than when alone. Latané and Darley attributed it to diffusion of responsibility and pluralistic ignorance. The presence of others inhibits, rather than encourages, helping.
- In Stanley Milgram's obedience studies, which experimental variation produced the LOWEST rate of full obedience (delivering the maximum shock)?
- When the experimenter wore a lab coat
- When the learner was in a separate room and only heard
- When the experimenter gave orders by telephone from another room
- When two confederate 'teachers' also obeyed first
Correct answer: When the experimenter gave orders by telephone from another room
Obedience dropped sharply when the experimenter issued orders by telephone from a distance rather than in person, because the authority's physical presence strongly sustains obedience. In this telephone condition, full obedience fell to roughly 20 percent, far below the baseline ~65 percent. Among the listed options, the telephone condition produced the lowest obedience rate; the lab-coat and voice-only conditions both yielded near-baseline compliance.
- A charity volunteer first asks neighbors to sign a harmless petition supporting clean water. A week later she returns and asks the same people to donate, and they agree at much higher rates than neighbors approached cold. The escalation from a small request to a larger one defines:
- The foot-in-the-door technique
- The door-in-the-face technique
- The that's-not-all technique
- Lowballing
Correct answer: The foot-in-the-door technique
This is the foot-in-the-door technique, in which agreeing to a small initial request increases compliance with a later, larger request. The earlier commitment shifts self-perception toward being a helpful, involved person. The door-in-the-face technique works in the opposite direction, starting with a large refused request.
- A juror concludes that an assault victim 'must have done something to provoke it,' reasoning that bad things happen to people who deserve them. This tendency to assume the world is fair and people get what they deserve is the:
- Self-serving bias
- Just-world hypothesis
- False consensus effect
- Actor-observer bias
Correct answer: Just-world hypothesis
This is the just-world hypothesis, the belief that the world is fundamentally fair so people get what they deserve and deserve what they get. Melvin Lerner showed it can lead observers to derogate or blame innocent victims to preserve the belief in a just world. It is a motivated bias, not an accurate appraisal of fairness.
- During a group brainstorming meeting, members suppress their doubts about a risky plan because they sense the leader favors it and they value group harmony. No one voices dissent and the flawed plan proceeds. Irving Janis labeled this faulty group decision process:
- Social loafing
- Risky shift
- Groupthink
- Group polarization
Correct answer: Groupthink
This is groupthink, in which a cohesive group's desire for harmony and unanimity overrides realistic appraisal of alternatives, suppressing dissent. Janis identified symptoms such as illusions of invulnerability and self-censorship. It is distinct from group polarization, which describes attitudes becoming more extreme after discussion.
- A commuter sees a stranger trip and drop her bags and immediately thinks 'what a clumsy person,' giving no thought to the icy sidewalk or the rushing crowd. Overweighting personal disposition while underweighting situation when judging others reflects the:
- Mere exposure effect
- Fundamental attribution error
- Bystander effect
- Self-serving bias
Correct answer: Fundamental attribution error
This is the fundamental attribution error, the tendency to overestimate dispositional (personality) causes and underestimate situational causes when explaining others' behavior. The observer ignored the icy pavement and credited the person's character instead. It applies most strongly to judgments of others rather than oneself.
- After a national sports rivalry, fans rate fans of their own team as friendly and diverse but dismiss rival fans as uniformly obnoxious. Favoring one's own group while derogating and over-generalizing about another group illustrates:
- The endowment effect
- Social facilitation
- Diffusion of responsibility
- In-group favoritism and out-group bias
Correct answer: In-group favoritism and out-group bias
This reflects in-group favoritism paired with out-group bias, in which people view their own group more positively and perceive out-group members as more similar to one another (the out-group homogeneity effect). Tajfel's social identity theory links this to deriving self-esteem from group membership. Even minimal, arbitrary group assignments can trigger it.
- A psychologist studies how the presence of an audience affects a skilled pianist performing a well-rehearsed piece versus an unfamiliar one. Based on social facilitation research, the audience is most likely to:
- Improve both performances equally
- Have no measurable effect on either
- Improve the rehearsed performance and impair the unfamiliar one
- Impair both performances equally
Correct answer: Improve the rehearsed performance and impair the unfamiliar one
Social facilitation predicts that the presence of others enhances performance on well-learned or simple tasks (the dominant, correct response) but impairs performance on novel or complex tasks. Zajonc explained this through heightened arousal strengthening the dominant response. So the rehearsed piece improves while the unfamiliar one suffers.
- In a smoke-filled-room study, a lone participant who notices smoke seeping in usually reports it quickly, but participants seated with calm, unreactive confederates often sit passively and say nothing. The confederates' non-reaction leads each person to misread the situation as non-threatening, an effect called:
- The just-world hypothesis
- Pluralistic ignorance
- Reactance
- Group polarization
Correct answer: Pluralistic ignorance
This is pluralistic ignorance, in which each individual privately senses a problem but, seeing others stay calm, wrongly concludes there is no emergency. Latané and Darley showed this contributes to bystander inaction. People take others' inaction as evidence that nothing is wrong, suppressing their own response.
- A study finds that group discussion among already cautious investors makes the group's final risk tolerance even lower than its members' individual pre-discussion averages. This intensification of a group's prevailing tendency after discussion is known as:
- Deindividuation
- Group polarization
- Groupthink
- Social loafing
Correct answer: Group polarization
This is group polarization, the tendency for group discussion to strengthen members' initial leanings, producing a more extreme group position than the average individual held beforehand. A cautious group becomes more cautious, just as a risk-tolerant one becomes riskier (the risky shift). It differs from groupthink, which centers on suppressing dissent to preserve harmony.
- A toddler who has learned to call all four-legged furry animals 'doggie' encounters a cat and says 'doggie.' When corrected, the child gradually revises the mental category to distinguish cats from dogs. In Piaget's terms, fitting the cat into the existing 'doggie' category illustrates one process and revising the category illustrates another. Which pair correctly labels them, in that order?
- Assimilation, then accommodation
- Accommodation, then assimilation
- Equilibration, then decentration
- Conservation, then centration
Correct answer: Assimilation, then accommodation
Assimilation, then accommodation is correct. Assimilation means interpreting new information using existing schemas, so labeling the cat 'doggie' fits the cat into the current schema. Accommodation means modifying schemas to fit new information, so revising the category to separate cats from dogs adjusts the schema. The reverse ordering reverses the two definitions.
- In Ainsworth's Strange Situation, an infant explores the room freely while the caregiver is present, becomes visibly upset when the caregiver leaves, and is quickly soothed and resumes play upon reunion. Which attachment classification does this pattern best represent?
- Insecure-avoidant attachment
- Disorganized attachment
- Secure attachment
- Insecure-resistant (ambivalent) attachment
Correct answer: Secure attachment
Secure attachment is correct. Securely attached infants use the caregiver as a secure base for exploration, show distress at separation, and are readily comforted and re-engage with play at reunion. Avoidant infants show little distress and ignore the caregiver, while resistant infants are distressed but cannot be soothed and may resist contact.
- In the Strange Situation, one infant shows little distress when the caregiver departs and actively avoids or ignores the caregiver upon return, appearing indifferent. According to Ainsworth's research, this avoidant pattern is most commonly associated with which style of caregiving?
- Consistently unresponsive or rejecting caregiving
- Inconsistent, unpredictably responsive caregiving
- Consistently sensitive and responsive caregiving
- Frightening or frightened caregiving
Correct answer: Consistently unresponsive or rejecting caregiving
Consistently unresponsive or rejecting caregiving is correct. Avoidant attachment develops when caregivers reliably rebuff or ignore the infant's bids for comfort, so the infant learns to minimize attachment behavior. Sensitive caregiving produces secure attachment, inconsistent caregiving produces resistant attachment, and frightening caregiving is linked to disorganized attachment.
- A researcher argues that there is a limited window early in life during which a songbird must hear its species' song to develop normal singing, and that exposure later cannot fully compensate. This claim is an application of which developmental concept?
- Reciprocal determinism
- A critical (sensitive) period
- Habituation
- Conservation
Correct answer: A critical (sensitive) period
A critical (sensitive) period is correct. A critical period is a specific developmental window during which an organism is biologically primed to acquire a particular skill or characteristic and after which acquisition is far harder or impossible. Habituation refers to declining response to a repeated stimulus, unrelated to a time window.
- According to Erik Erikson, the central psychosocial conflict of infancy (roughly the first year), shaped largely by the consistency and reliability of caregiving, is best described as:
- Trust versus mistrust
- Initiative versus guilt
- Industry versus inferiority
- Autonomy versus shame and doubt
Correct answer: Trust versus mistrust
Trust versus mistrust is correct. Erikson's first psychosocial stage spans roughly the first year, when responsive, dependable caregiving leads the infant to develop basic trust in the world. Autonomy versus shame and doubt is the toddler stage, while initiative versus guilt and industry versus inferiority occur in early and middle childhood respectively.
- A school-aged child between roughly ages 6 and 12 who masters academic and social skills and earns recognition for competence is, in Erikson's framework, successfully resolving which psychosocial crisis?
- Intimacy versus isolation
- Industry versus inferiority
- Generativity versus stagnation
- Identity versus role confusion
Correct answer: Industry versus inferiority
Industry versus inferiority is correct. Erikson placed this crisis in middle childhood, when children develop a sense of competence by succeeding at school, tasks, and peer activities; failure breeds feelings of inferiority. Identity versus role confusion is the adolescent stage, and intimacy and generativity belong to adulthood.
- In Harry Harlow's experiments, infant rhesus monkeys were given access to a wire mother that dispensed milk and a cloth-covered mother that provided no food. Which outcome did Harlow observe, and what did it demonstrate?
- The monkeys ignored both surrogates equally, showing attachment requires a living caregiver
- The monkeys alternated equally between the two, showing feeding and comfort are equally weighted
- The monkeys clung to the cloth mother for comfort and used her as a base when frightened, showing contact comfort matters more than feeding
- The monkeys preferred the wire mother, showing attachment is driven mainly by feeding
Correct answer: The monkeys clung to the cloth mother for comfort and used her as a base when frightened, showing contact comfort matters more than feeding
The monkeys preferring the cloth mother for comfort is correct. Harlow found infant monkeys spent most time clinging to the soft cloth surrogate and ran to it when frightened, going to the wire mother only to feed. This challenged the prevailing 'cupboard' view that attachment forms simply because the caregiver provides food, highlighting contact comfort.
- A child reasons that stealing a drug to save a dying spouse is acceptable because human life is worth more than the druggist's profit, appealing to broad ethical principles rather than to laws or rewards. In Kohlberg's theory, this reasoning best reflects which level?
- Premoral reasoning
- Conventional morality
- Preconventional morality
- Postconventional morality
Correct answer: Postconventional morality
Postconventional morality is correct. At Kohlberg's highest level, moral judgments rest on abstract, self-chosen ethical principles such as the value of human life, which can override specific laws. Preconventional reasoning focuses on punishment and self-interest, while conventional reasoning emphasizes social approval and maintaining law and order.
- A child says it is wrong to cross the street against the light 'because a police officer might catch you and you'd get in trouble.' In Kohlberg's stages of moral development, this focus on avoiding punishment places the reasoning at which level?
- Autonomous morality
- Preconventional morality
- Conventional morality
- Postconventional morality
Correct answer: Preconventional morality
Preconventional morality is correct. Kohlberg's preconventional level bases moral judgments on direct consequences to the self, such as avoiding punishment or gaining rewards. Reasoning that emphasizes social rules and approval would be conventional, and reasoning based on universal principles would be postconventional.
- Twin studies that compare identical twins raised apart with fraternal twins are most directly designed to address which long-standing question in developmental psychology?
- Whether development proceeds in continuous or discontinuous stages
- Whether early experience has a critical period
- The relative contributions of heredity and environment to a trait (the nature versus nurture debate)
- The order in which language milestones emerge
Correct answer: The relative contributions of heredity and environment to a trait (the nature versus nurture debate)
The relative contributions of heredity and environment is correct. Twin and adoption studies estimate how much variation in a trait is attributable to genetic versus environmental factors, which is the core of the nature versus nurture debate. The continuity question and the critical-period question are separate developmental issues.
- A 6-month-old watches a toy being hidden under a blanket and immediately loses interest, acting as if the toy no longer exists. According to Piaget, the infant's failure to search reflects the not-yet-developed ability known as:
- Conservation
- Theory of mind
- Reversibility
- Object permanence
Correct answer: Object permanence
Object permanence is correct. Object permanence is the understanding that objects continue to exist even when they cannot be seen, heard, or touched; Piaget held it develops during the sensorimotor stage. Conservation concerns quantity remaining constant despite shape changes, and theory of mind concerns understanding others' mental states.
- A 4-year-old in Piaget's preoperational stage watches water poured from a short, wide glass into a tall, thin glass and insists the tall glass now holds more water. This error most directly reflects which feature of preoperational thought?
- Deferred imitation
- Centration on a single dimension (height)
- Hypothetico-deductive reasoning
- Object permanence
Correct answer: Centration on a single dimension (height)
Centration on a single dimension is correct. Preoperational children focus on one salient feature, here the height of the water, and ignore compensating changes such as the narrower width, which is why they fail conservation tasks. The ability to consider multiple dimensions and reversibility emerges in the concrete operational stage.
- Which sequence correctly orders Piaget's four stages of cognitive development from earliest to latest?
- Sensorimotor, concrete operational, preoperational, formal operational
- Preoperational, sensorimotor, concrete operational, formal operational
- Sensorimotor, preoperational, concrete operational, formal operational
- Preoperational, sensorimotor, formal operational, concrete operational
Correct answer: Sensorimotor, preoperational, concrete operational, formal operational
Sensorimotor, preoperational, concrete operational, formal operational is correct. Piaget proposed development moves from the sensorimotor stage (birth to about age 2), through preoperational (about 2 to 7), to concrete operational (about 7 to 11), and finally formal operational (about 12 and up). The other orderings misplace one or more stages.
- A toddler is given a series of standardized separation-and-reunion episodes and shows highly contradictory behavior at reunion, such as approaching the caregiver while looking away, freezing, or appearing dazed. Which attachment classification, added after Ainsworth's original three, best describes this pattern?
- Secure attachment
- Insecure-avoidant attachment
- Insecure-resistant attachment
- Disorganized attachment
Correct answer: Disorganized attachment
Disorganized attachment is correct. Main and Solomon added the disorganized category for infants who lack a coherent strategy, showing contradictory, frozen, or disoriented behaviors at reunion, often linked to frightening or frightened caregiving. Secure, avoidant, and resistant each involve organized, predictable patterns of behavior.
- A typically developing child produces single words around 12 months, two-word combinations such as 'more milk' around 18 to 24 months, and longer telegraphic phrases thereafter. The two-word stage that omits function words like articles and prepositions is commonly called:
- Babbling
- Telegraphic speech
- Overregularization
- Holophrastic speech
Correct answer: Telegraphic speech
Telegraphic speech is correct. Telegraphic speech describes early two-word and short utterances that contain mostly content words and omit grammatical morphemes, much like a telegram. Babbling precedes real words, holophrastic speech is the single-word stage, and overregularization is misapplying grammatical rules such as saying 'goed.'
- A preschooler who has correctly said 'went' begins saying 'goed' and 'foots,' applying grammatical rules too broadly. In language development this phenomenon is known as overregularization, and it is generally interpreted as evidence that the child:
- Lacks any grammatical knowledge
- Is regressing in language ability
- Has learned abstract grammatical rules and is applying them, even to irregular forms
- Is simply imitating adult speech word for word
Correct answer: Has learned abstract grammatical rules and is applying them, even to irregular forms
Has learned grammatical rules and is applying them broadly is correct. Overregularization, such as 'goed' for 'went,' shows the child has internalized productive rules like adding '-ed' for past tense and applies them even to irregular words, which signals rule learning rather than mere imitation or regression.
- In a false-belief task, a child watches Sally place a marble in a basket and leave; Anne then moves it to a box. Asked where Sally will look for the marble upon return, a 3-year-old typically says 'the box,' while most 4- to 5-year-olds say 'the basket.' Passing this task is taken as evidence the child has developed:
- Object permanence
- Theory of mind
- Conservation
- Egocentric speech
Correct answer: Theory of mind
Theory of mind is correct. Theory of mind is the understanding that others hold mental states, including beliefs that can differ from reality and from one's own knowledge. Saying Sally will look in the basket shows the child can represent Sally's false belief. Object permanence and conservation concern physical objects, not mental states.
- A teacher gives a student math problems that the student cannot yet solve alone but can solve with hints and prompts from the teacher. Vygotsky would describe the gap between what the student can do independently and what the student can do with such guidance as the:
- Preoperational gap
- Zone of proximal development
- Concrete operational stage
- Critical period
Correct answer: Zone of proximal development
Zone of proximal development is correct. For Vygotsky, the zone of proximal development is the range between what a learner can accomplish independently and what the learner can accomplish with assistance from a more knowledgeable other. Teaching that targets this zone, often through temporary support called scaffolding, is most effective.
- Diana Baumrind classified parenting styles along the dimensions of warmth (responsiveness) and control (demandingness). The style that combines high warmth with high but reasonable control, and that is associated with the most favorable child outcomes such as self-reliance and social competence, is termed:
- Permissive
- Authoritarian
- Authoritative
- Uninvolved (neglectful)
Correct answer: Authoritative
Authoritative is correct. Authoritative parenting pairs high responsiveness with firm, reasonable demands and is linked to high self-esteem, social competence, and academic success. Authoritarian parenting is high control but low warmth, permissive is high warmth but low control, and uninvolved is low on both.
- A parent enforces strict rules and expects unquestioned obedience, offering little warmth and rarely explaining the reasons behind demands. In Baumrind's framework this describes authoritarian parenting, which research associates with child outcomes such as:
- High self-reliance and strong social skills
- Obedience paired with lower self-esteem and weaker social competence
- Detachment stemming from a lack of any rules
- Impulsivity and difficulty respecting any authority
Correct answer: Obedience paired with lower self-esteem and weaker social competence
Obedience paired with lower self-esteem and weaker social competence is correct. Authoritarian parenting, high in control but low in warmth, tends to produce children who are obedient but more anxious, with lower self-esteem and poorer social skills. The impulsivity pattern is more typical of permissive parenting, and detachment is associated with uninvolved parenting.
- A developmental researcher studies whether early temperament predicts later sociability and notes that a child's inborn dispositions and the parenting environment continually shape each other over time. This emphasis on the ongoing interplay of biology and experience is best characterized as:
- A purely behaviorist (blank-slate) position
- Evidence for a single critical period
- An interactionist view of nature and nurture
- A strict nativist position
Correct answer: An interactionist view of nature and nurture
An interactionist view of nature and nurture is correct. The modern consensus is that heredity and environment continuously interact, with genetic predispositions and experiences mutually influencing development rather than one acting alone. A strict nativist position credits biology almost entirely, while a blank-slate position credits experience almost entirely.
- A clinician diagnoses major depressive disorder. According to DSM-5-TR, a major depressive episode requires at least five symptoms present during the same two-week period, and at least one of those symptoms must be either depressed mood or which of the following?
- Recurrent thoughts of death
- Loss of interest or pleasure in nearly all activities
- Significant change in weight or appetite
- Diminished ability to concentrate
Correct answer: Loss of interest or pleasure in nearly all activities
Loss of interest or pleasure (anhedonia) in nearly all activities is the required core symptom. Under DSM-5-TR, a major depressive episode requires five or more symptoms in a two-week window, and at least one must be either depressed mood or markedly diminished interest/pleasure. Weight change, death thoughts, and concentration problems are also diagnostic symptoms, but they are not the mandatory core anchors and cannot satisfy the criterion on their own.
- A 28-year-old reports excessive worry about work, finances, and family occurring more days than not for the past eight months, accompanied by restlessness, muscle tension, and difficulty controlling the worry. This presentation best matches the DSM-5-TR criteria for which disorder?
- Adjustment disorder
- Generalized anxiety disorder
- Panic disorder
- Specific phobia
Correct answer: Generalized anxiety disorder
Generalized anxiety disorder is defined by excessive, hard-to-control worry about multiple domains occurring more days than not for at least six months, with associated symptoms such as restlessness, fatigue, muscle tension, and concentration problems. Panic disorder centers on recurrent unexpected panic attacks rather than chronic worry, and the duration here exceeds the brief, stressor-linked course of adjustment disorder.
- A person experiences distinct periods of elevated, expansive mood with decreased need for sleep, grandiosity, and pressured speech that last about a week and impair work functioning, alternating over time with major depressive episodes. This pattern is most consistent with which disorder?
- Persistent depressive disorder
- Bipolar I disorder
- Bipolar II disorder
- Cyclothymic disorder
Correct answer: Bipolar I disorder
Bipolar I disorder is defined by the presence of at least one full manic episode, marked by elevated or irritable mood with symptoms such as decreased need for sleep, grandiosity, and pressured speech causing marked impairment. Bipolar II requires hypomanic (not manic) episodes plus major depression, and cyclothymia involves milder, subthreshold fluctuations that never meet full episode criteria.
- Borderline personality disorder is characterized in DSM-5-TR by a pervasive pattern of instability. Which cluster of features is most central to this diagnosis?
- Detachment from social relationships and restricted emotion
- Preoccupation with orderliness, perfectionism, and control
- Instability of relationships, self-image, and affect with marked impulsivity
- Excessive emotionality and attention-seeking
Correct answer: Instability of relationships, self-image, and affect with marked impulsivity
Instability of interpersonal relationships, self-image, and affect together with marked impulsivity is the defining feature of borderline personality disorder, often including frantic efforts to avoid abandonment and recurrent self-harm. Excessive emotionality describes histrionic personality, social detachment describes schizoid personality, and rigid preoccupation with order describes obsessive-compulsive personality disorder.
- A student develops an intense fear of dogs after being bitten, and now experiences fear even at the sight of a leash. From a learning-theory perspective on phobia acquisition, the previously neutral dog became a feared stimulus through which process?
- Observational learning
- Systematic desensitization
- Classical conditioning
- Operant conditioning
Correct answer: Classical conditioning
Classical conditioning explains how phobias form when a neutral stimulus (the dog) is paired with an aversive unconditioned stimulus (the bite), so the dog becomes a conditioned stimulus that elicits fear. This is the mechanism in Watson and Rayner's Little Albert demonstration. Operant conditioning involves consequences shaping behavior, and systematic desensitization is a treatment, not an acquisition process.
- A cognitive-behavioral therapist helps a client identify the thought "If I make one mistake, everyone will think I am worthless" and then examine evidence for and against it. This specific CBT technique is best described as:
- Cognitive restructuring
- Flooding
- Free association
- Token economy
Correct answer: Cognitive restructuring
Cognitive restructuring is the CBT technique of identifying, evaluating, and challenging distorted automatic thoughts and replacing them with more balanced appraisals. Free association is psychoanalytic, flooding is an exposure-based behavioral method, and a token economy is an operant reinforcement system, none of which involve directly examining the evidence for a maladaptive belief.
- In the DSM-5-TR, disorders are organized into broad diagnostic categories. Conditions such as schizophrenia, schizoaffective disorder, and delusional disorder are grouped under which category?
- Anxiety disorders
- Schizophrenia spectrum and other psychotic disorders
- Neurodevelopmental disorders
- Dissociative disorders
Correct answer: Schizophrenia spectrum and other psychotic disorders
Schizophrenia spectrum and other psychotic disorders is the DSM-5-TR category that includes schizophrenia, schizoaffective disorder, schizophreniform disorder, brief psychotic disorder, and delusional disorder, all unified by abnormalities in domains such as delusions, hallucinations, and disorganized thinking. Anxiety, dissociative, and neurodevelopmental disorders are separate chapters with distinct defining features.
- According to Freud, the defense mechanism in which a person attributes their own unacceptable impulses to another person, such as an angry individual insisting that others are hostile toward them, is called:
- Projection
- Reaction formation
- Sublimation
- Displacement
Correct answer: Projection
Projection is the defense mechanism of attributing one's own unacceptable thoughts, feelings, or impulses to someone else. Sublimation channels unacceptable impulses into socially valued activities, reaction formation expresses the opposite of an impulse, and displacement redirects an impulse onto a safer target rather than assigning it to another person.
- In Freud's theory of psychosexual development, fixation during the stage in which the child's pleasure centers on bowel and bladder control, roughly ages one to three, is classically linked to traits such as orderliness or messiness. This is which stage?
- Anal stage
- Oral stage
- Latency stage
- Phallic stage
Correct answer: Anal stage
The anal stage (about ages one to three) centers on toilet training and control of elimination, and Freud linked fixation here to anal-retentive (orderly, stubborn) or anal-expulsive (messy) traits. The oral stage focuses on the mouth, the phallic stage on the genitals and the Oedipal conflict, and the latency stage on dormant sexual interests during middle childhood.
- A client reports recurrent, intrusive, unwanted thoughts about contamination that cause significant anxiety, which they attempt to neutralize through repeated, ritualized handwashing. In DSM-5-TR terms, the intrusive thoughts and the repetitive handwashing represent, respectively:
- Delusions and hallucinations
- Phobias and avoidance
- Obsessions and compulsions
- Manic ideation and impulsivity
Correct answer: Obsessions and compulsions
In obsessive-compulsive disorder, obsessions are recurrent, intrusive, unwanted thoughts, urges, or images that provoke anxiety, while compulsions are repetitive behaviors or mental acts performed to reduce that distress. The contamination thoughts are the obsessions and the ritualized handwashing is the compulsion. Delusions and hallucinations are psychotic features, not the hallmark of OCD.
- In Maslow's hierarchy of needs, which need must generally be satisfied before a person is fully motivated to pursue self-actualization?
- Self-transcendence needs
- Aesthetic needs alone
- Cognitive needs alone
- Physiological and safety needs
Correct answer: Physiological and safety needs
Maslow's hierarchy proposes that lower-level deficiency needs, beginning with physiological and safety needs and then belongingness and esteem, must be largely met before a person can pursue self-actualization at the top. Self-actualization is the growth need to realize one's full potential, and it cannot be the dominant motive while basic survival and security needs remain unmet.
- The Five-Factor Model (Big Five) of personality describes individual differences along five broad dimensions. Which set correctly lists those five traits?
- Sensing, intuition, thinking, feeling, judging
- Oral, anal, phallic, latency, genital
- Openness, conscientiousness, extraversion, agreeableness, neuroticism
- Id, ego, superego, libido, fixation
Correct answer: Openness, conscientiousness, extraversion, agreeableness, neuroticism
The Big Five traits are openness, conscientiousness, extraversion, agreeableness, and neuroticism, often remembered by the acronym OCEAN. The Freudian structures and psychosexual stages are not personality trait dimensions, and sensing, intuition, thinking, feeling, and judging are components of the Myers-Briggs typology, not the Five-Factor Model.
- A clinician distinguishes the symptoms of schizophrenia into two groups. Hallucinations and delusions, which represent additions to normal experience, are classified as which type of symptom?
- Prodromal symptoms
- Positive symptoms
- Negative symptoms
- Cognitive symptoms
Correct answer: Positive symptoms
Positive symptoms of schizophrenia are excesses or distortions added to normal functioning, such as hallucinations, delusions, and disorganized speech. Negative symptoms reflect a loss or reduction of normal functions, such as flat affect, avolition, and social withdrawal. Cognitive symptoms involve impaired attention and working memory, and the prodrome refers to an early phase, not a symptom class.
- A therapist describes their orientation as helping the client achieve self-actualization through unconditional positive regard, empathy, and genuineness, focusing on present growth rather than uncovering repressed unconscious conflicts. This contrast best illustrates which distinction?
- Behavioral therapy versus cognitive therapy
- Group therapy versus individual therapy
- Pharmacotherapy versus psychotherapy
- Humanistic therapy versus psychodynamic therapy
Correct answer: Humanistic therapy versus psychodynamic therapy
This contrast captures humanistic therapy versus psychodynamic therapy. Humanistic approaches, exemplified by Carl Rogers's person-centered therapy, emphasize growth, the present, and the therapeutic conditions of empathy, genuineness, and unconditional positive regard. Psychodynamic therapy instead focuses on insight into unconscious conflicts and early experiences, often through techniques like free association and interpretation of transference.
- A psychologist uses a behavioral treatment that pairs deep muscle relaxation with a gradually ascending hierarchy of feared situations so that the client can no longer feel anxious and relaxed at the same time. This counterconditioning approach was developed by whom?
- Albert Bandura
- B. F. Skinner
- Carl Rogers
- Joseph Wolpe
Correct answer: Joseph Wolpe
Joseph Wolpe developed systematic desensitization, which uses reciprocal inhibition by pairing relaxation with a graded hierarchy of feared stimuli so that relaxation displaces the anxiety response. Skinner is associated with operant conditioning, Bandura with observational learning and modeling, and Rogers with person-centered humanistic therapy.
- A 7-year-old shows persistent deficits in social communication and reciprocity along with restricted, repetitive patterns of behavior and interests, with onset in the early developmental period. In DSM-5-TR, this presentation is captured under which single diagnostic label?
- Attention-deficit/hyperactivity disorder
- Autism spectrum disorder
- Conduct disorder
- Specific learning disorder
Correct answer: Autism spectrum disorder
Autism spectrum disorder is the DSM-5-TR diagnosis that combines persistent deficits in social communication and social interaction with restricted, repetitive behaviors, interests, or activities, with symptoms present from early development. DSM-5 merged earlier categories such as autistic disorder and Asperger's into this single spectrum diagnosis with severity specifiers.
- Antipsychotic medications that primarily block dopamine D2 receptors are most effective at reducing which feature of schizophrenia?
- Cognitive deficits in working memory
- Negative symptoms such as flat affect
- Positive symptoms such as delusions and hallucinations
- Depressive comorbidity
Correct answer: Positive symptoms such as delusions and hallucinations
Typical (first-generation) antipsychotics that block dopamine D2 receptors are most effective against positive symptoms such as delusions and hallucinations, consistent with the dopamine hypothesis of schizophrenia. They are generally far less effective for the negative symptoms (such as flat affect and avolition) and the cognitive deficits, which is one reason these symptom domains are harder to treat.
- An individual with antisocial personality disorder, beginning in conduct-disorder behaviors before age 15, most characteristically displays which pattern in adulthood?
- Grandiose fantasies and need for excessive admiration
- A pervasive disregard for and violation of the rights of others
- Excessive need to be taken care of and difficulty making decisions
- An intense fear of social evaluation and avoidance of relationships
Correct answer: A pervasive disregard for and violation of the rights of others
Antisocial personality disorder is defined by a pervasive pattern of disregard for and violation of the rights of others, often including deceitfulness, impulsivity, irritability, and lack of remorse, with evidence of conduct disorder before age 15. Fear of evaluation describes avoidant personality, dependency describes dependent personality, and grandiose need for admiration describes narcissistic personality disorder.
- In Albert Ellis's rational emotive behavior therapy, the ABC model holds that emotional consequences are driven not directly by activating events but primarily by which intervening factor?
- Unconscious childhood conflicts
- Reinforcement contingencies
- Neurotransmitter imbalances
- Irrational beliefs about the event
Correct answer: Irrational beliefs about the event
In Ellis's ABC model, the activating event (A) does not directly cause the emotional consequence (C); rather, it is the person's beliefs (B), especially irrational beliefs, that drive the emotional response. Therapy targets disputing those irrational beliefs. This cognitive emphasis distinguishes REBT from psychodynamic, behavioral, and biological explanations.
- A clinician must rule out medical and substance causes before assigning a primary mental disorder diagnosis. This requirement reflects which general principle in the DSM-5-TR diagnostic process?
- Diagnoses are assigned only after one year of symptoms
- Differential diagnosis requires excluding other plausible explanations
- Self-report is sufficient for any diagnosis
- A symptom can never appear in more than one disorder
Correct answer: Differential diagnosis requires excluding other plausible explanations
Requiring the clinician to rule out medical conditions and substance effects reflects the principle of differential diagnosis: a diagnosis is assigned only after other plausible explanations for the symptoms have been excluded. DSM-5-TR criteria routinely include exclusion clauses (for example, symptoms not attributable to a substance or another medical condition) precisely to support this reasoning.
- A person experiences recurrent, unexpected surges of intense fear that peak within minutes, accompanied by heart palpitations, shortness of breath, and a fear of dying, followed by persistent worry about having additional attacks. This is most consistent with which DSM-5-TR diagnosis?
- Panic disorder
- Agoraphobia alone
- Specific phobia
- Social anxiety disorder
Correct answer: Panic disorder
Panic disorder involves recurrent, unexpected panic attacks (abrupt surges of intense fear peaking within minutes with symptoms such as palpitations and shortness of breath) plus persistent concern about further attacks or maladaptive behavior change. Specific phobia and social anxiety disorder involve fear cued by identifiable objects or social situations rather than unexpected attacks.
- Electroconvulsive therapy (ECT) is most commonly indicated as a treatment for which clinical situation?
- Severe major depression that has not responded to medication, especially with high suicide risk
- Specific phobias of animals
- Obsessive-compulsive personality disorder
- Mild, first-episode generalized anxiety
Correct answer: Severe major depression that has not responded to medication, especially with high suicide risk
ECT is most commonly used for severe major depression that is treatment-resistant or that requires rapid response, such as when suicide risk is high or the patient is not eating. It is not a first-line treatment for mild anxiety or specific phobias, and it is not a treatment for personality disorders, which are addressed primarily through psychotherapy.
- A therapist asks a client to gradually and repeatedly approach a feared situation in real life while preventing avoidance and escape, allowing anxiety to decline naturally over time. This core behavioral technique is best labeled:
- Exposure therapy
- Biofeedback
- Dream analysis
- Reflective listening
Correct answer: Exposure therapy
Exposure therapy is the behavioral technique in which clients confront feared stimuli or situations, in vivo or imaginally, while resisting avoidance, so that anxiety habituates and the feared outcome is disconfirmed. It is a cornerstone of treatment for phobias, panic disorder, and OCD. Dream analysis and reflective listening come from other orientations, and biofeedback targets physiological control rather than direct confrontation of fears.
- In DSM-5-TR, a chronic, low-grade depressed mood that is present more days than not for at least two years in adults, never absent for more than two months at a time, best matches which diagnosis?
- Bipolar II disorder
- Major depressive disorder
- Persistent depressive disorder (dysthymia)
- Disruptive mood dysregulation disorder
Correct answer: Persistent depressive disorder (dysthymia)
Persistent depressive disorder, formerly called dysthymia, is defined by depressed mood for most of the day, more days than not, for at least two years in adults, without a symptom-free interval longer than two months. Major depressive disorder requires a more acute episode of at least two weeks with five symptoms, while bipolar II requires hypomania and major depression.
- A client with borderline personality disorder tends to view a caregiver as entirely wonderful one day and entirely worthless the next. This rapid alternation between idealization and devaluation reflects which characteristic defense?
- Regression
- Sublimation
- Splitting
- Intellectualization
Correct answer: Splitting
Splitting is the defense, central to borderline personality disorder, in which a person fails to integrate positive and negative qualities into a coherent whole, so others are seen as all-good or all-bad in alternation. Sublimation channels impulses into productive activity, intellectualization avoids emotion through abstraction, and regression involves reverting to earlier developmental behaviors.
- A therapist who deliberately answers a client's anxiety with calm acceptance and helps the client tolerate distressing emotions through mindfulness, distress tolerance, and emotion regulation skills is using an approach originally designed primarily for which population?
- People with specific phobias
- Patients in acute manic episodes
- Individuals with borderline personality disorder and chronic suicidality
- Children with autism spectrum disorder
Correct answer: Individuals with borderline personality disorder and chronic suicidality
Dialectical behavior therapy, developed by Marsha Linehan, was originally designed for individuals with borderline personality disorder and chronic suicidal or self-harm behavior, combining mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness skills with acceptance and change strategies. It was not created for autism, acute mania, or simple phobias.
- A man experiences a sudden, severe depressive episode only weeks after a manic episode that included reckless spending and psychotic grandiosity. The presence of at least one full manic episode means his overall diagnosis is which of the following, regardless of the depressive episodes?
- Major depressive disorder with anxious distress
- Bipolar I disorder
- Cyclothymic disorder
- Bipolar II disorder
Correct answer: Bipolar I disorder
Bipolar I disorder is diagnosed when a person has had at least one full manic episode, even if depressive or hypomanic episodes also occur; the manic episode here, with psychotic features and marked impairment, establishes the diagnosis. Bipolar II requires hypomania without a full manic episode, and major depressive disorder is excluded once a manic episode has occurred.
- A researcher reports that hours of sleep and exam scores have a Pearson correlation coefficient of r = +0.80. What does this value indicate?
- A weak relationship that is unlikely to be statistically significant
- That more sleep causes higher exam scores
- That 80 percent of the variation in scores is explained by sleep
- A strong positive linear relationship between the two variables
Correct answer: A strong positive linear relationship between the two variables
A strong positive linear relationship is correct. A correlation coefficient ranges from -1 to +1, where the sign shows direction and the absolute value shows strength; +0.80 is close to +1, so as one variable increases the other tends to increase strongly. The coefficient alone cannot establish causation, and the proportion of variance explained is r squared (0.64), not 0.80.
- A news report states that children who eat breakfast score higher on standardized tests, concluding that breakfast boosts test performance. A methodologist objects that this is an overreach. What principle supports the objection?
- A Type I error has been committed
- The empirical rule applies only to normal distributions
- Random assignment guarantees external validity
- Correlation does not imply causation
Correct answer: Correlation does not imply causation
Correlation does not imply causation is correct. A correlational finding cannot establish that one variable produces changes in another because a third (confounding) variable, such as family income or home stability, could drive both breakfast habits and test scores, and the direction of any effect is undetermined. Only a controlled experiment with manipulation and random assignment can support a causal claim.
- In a study testing whether a new drug reduces anxiety, neither the participants nor the researchers administering the pills know who receives the drug versus the placebo. What is this design called?
- A double-blind study
- A naturalistic observation
- A single-blind study
- A matched-pairs design
Correct answer: A double-blind study
A double-blind study is correct. In a double-blind design, both the participants and the experimenters interacting with them are unaware of group assignments, which controls for participant expectancy effects and experimenter bias simultaneously. A single-blind study conceals the assignment only from participants, leaving experimenter bias uncontrolled.
- An experimenter manipulates the amount of caffeine participants consume and then measures their reaction time. In this study, reaction time is which type of variable?
- A confounding variable
- The independent variable
- The dependent variable
- An extraneous control variable
Correct answer: The dependent variable
The dependent variable is correct. The dependent variable is the outcome that is measured and is expected to depend on, or change in response to, the manipulation. The independent variable is the factor the experimenter deliberately manipulates, which here is the amount of caffeine consumed.
- A study finds a strong effect under tightly controlled lab conditions but a researcher worries the results may not generalize to real-world settings. Which two concepts is the researcher weighing against each other?
- Random sampling versus random assignment
- Type I error versus Type II error
- Reliability versus validity
- Internal validity versus external validity
Correct answer: Internal validity versus external validity
Internal validity versus external validity is correct. Internal validity is the degree to which a study establishes a true cause-and-effect relationship free of confounds, often maximized by tight control, whereas external validity is the extent to which findings generalize to other people, settings, and times. Tight laboratory control can boost internal validity while limiting external validity.
- A psychologist records the following set of reaction times in milliseconds: 200, 210, 210, 220, 900. Which measure of central tendency is most distorted by the value of 900 and would overstate the typical score?
- The mean
- The range
- The median
- The mode
Correct answer: The mean
The mean is correct. The mean is the arithmetic average and is pulled toward extreme values (outliers), so the score of 900 inflates it well above the typical reaction time. The median (the middle value, 210) and the mode (the most frequent value, 210) are resistant to outliers, making them more representative here.
- Scores on a well-normed intelligence test are normally distributed with a mean of 100 and a standard deviation of 15. Approximately what percentage of people score between 85 and 115?
- About 95 percent
- About 68 percent
- About 99.7 percent
- About 50 percent
Correct answer: About 68 percent
About 68 percent is correct. By the empirical (68-95-99.7) rule for a normal distribution, roughly 68 percent of values fall within one standard deviation of the mean; here 85 and 115 are exactly one standard deviation (15 points) below and above 100. About 95 percent would fall within two standard deviations (70 to 130).
- In a study testing whether a tutoring program improves grades, which statement correctly expresses the null hypothesis?
- The sample is too small to detect an effect
- The tutoring program has no effect on grades
- The tutoring program significantly improves grades
- The tutoring program worsens grades
Correct answer: The tutoring program has no effect on grades
The tutoring program has no effect on grades is correct. The null hypothesis states that there is no difference, no relationship, or no effect in the population; the goal of significance testing is to gather evidence to reject it. A statement predicting that the program improves grades is the alternative (research) hypothesis.
- A researcher studying aggression decides to measure it as the number of times a participant presses a button to deliver a loud noise to a confederate. This specification is an example of what?
- A confounding variable
- An operational definition
- A construct validity threat
- A demand characteristic
Correct answer: An operational definition
An operational definition is correct. An operational definition specifies a concept in terms of the precise, observable procedures used to measure or manipulate it, turning an abstract construct like aggression into something countable. This allows other researchers to replicate the measurement exactly.
- A researcher draws participants from a population using a lottery so everyone has an equal chance of being selected, then uses a coin flip to place each selected person into the treatment or control group. Which terms correctly label these two procedures?
- Stratified sampling for both procedures
- Random sampling for selection and random assignment for group placement
- Counterbalancing for both procedures
- Random assignment for selection and random sampling for group placement
Correct answer: Random sampling for selection and random assignment for group placement
Random sampling for selection and random assignment for group placement is correct. Random sampling determines who is drawn from the population and supports generalizability (external validity), whereas random assignment determines which condition each participant experiences and equates groups to support causal inference (internal validity). The two serve different purposes and are not interchangeable.
- A bathroom scale that consistently reads 5 pounds too high every time someone steps on it best illustrates which combination of measurement properties?
- Both high reliability and high validity
- High reliability but low validity
- High validity but low reliability
- Both low reliability and low validity
Correct answer: High reliability but low validity
High reliability but low validity is correct. Reliability is consistency of measurement, and the scale is perfectly consistent (always 5 pounds over), but validity is whether it measures the true value, which it does not. A measure can be reliable without being valid, though it cannot be valid without being reliable.
- Two distributions have the same mean, but Distribution A has a standard deviation of 2 and Distribution B has a standard deviation of 10. What does this difference indicate?
- Distribution B has a higher average score
- Distribution A contains more extreme outliers
- Scores in Distribution B are more spread out around the mean
- Scores in Distribution A are more spread out around the mean
Correct answer: Scores in Distribution B are more spread out around the mean
Scores in Distribution B are more spread out around the mean is correct. The standard deviation measures the typical distance of scores from the mean, so a larger value (10) indicates greater variability or dispersion than a smaller value (2). Because both distributions share the same mean, the difference reflects spread, not average level.
- A study comparing two therapies yields a result with p = 0.02, using the conventional alpha level of 0.05. How should this be interpreted?
- The result is statistically significant, so the null hypothesis is rejected
- There is a 2 percent chance the alternative hypothesis is true
- The result proves the null hypothesis is false
- The therapies differ by an amount that is practically large
Correct answer: The result is statistically significant, so the null hypothesis is rejected
The result is statistically significant, so the null hypothesis is rejected is correct. The p value is the probability of obtaining the observed data (or more extreme) if the null hypothesis were true; because 0.02 is below the 0.05 threshold, the result is unlikely under the null and is deemed statistically significant. Statistical significance does not by itself establish that an effect is large or practically important.
- A researcher administers the same depression questionnaire to a group of adults and then again two weeks later, correlating the two sets of scores to see how stable the measure is over time. Which type of reliability is being assessed?
- Parallel-forms reliability
- Inter-rater reliability
- Internal consistency reliability
- Test-retest reliability
Correct answer: Test-retest reliability
Test-retest reliability is correct. Test-retest reliability evaluates the temporal stability of a measure by administering it to the same people on two occasions and correlating the scores. Internal consistency assesses whether items within a single administration measure the same construct, and inter-rater reliability assesses agreement between different observers.
- A researcher rejects the null hypothesis and concludes a treatment works, but in reality the treatment has no effect. This mistake is best described as which kind of error?
- A Type I error (false positive)
- A Type II error (false negative)
- A measurement error
- A sampling error
Correct answer: A Type I error (false positive)
A Type I error (false positive) is correct. A Type I error occurs when a true null hypothesis is rejected, meaning the researcher detects an effect that does not actually exist; its probability equals the alpha level. A Type II error is the opposite, failing to reject a false null hypothesis and missing a real effect.
- A scatterplot of two variables shows points scattered with no discernible pattern and a best-fit line that is essentially flat. What does this most likely indicate about the correlation coefficient?
- It cannot be computed from a scatterplot
- It is close to zero
- It is close to -1.0
- It is close to +1.0
Correct answer: It is close to zero
It is close to zero is correct. A correlation near zero means there is little or no linear relationship between the variables, which appears on a scatterplot as a cloud of points with no upward or downward trend. Values near +1.0 or -1.0 would show points tightly clustered along a rising or falling line.
- A researcher fails to reject the null hypothesis and concludes a new medication is ineffective, but the medication actually does work. Which factor most directly increases the risk of this error?
- Setting alpha at a very high level such as 0.10
- Low statistical power, often from a small sample size
- Increasing the effect size in the population
- Using random assignment to conditions
Correct answer: Low statistical power, often from a small sample size
Low statistical power, often from a small sample size, is correct. Failing to detect a real effect is a Type II error, and the probability of avoiding it is statistical power; small samples reduce power and increase the chance of missing a true effect. Larger effect sizes and larger samples increase power, reducing Type II error risk.
- A psychologist wants to know whether participants who score high on a measure of conscientiousness also tend to score high on a measure of academic motivation, without manipulating anything. Which research method is most appropriate?
- A double-blind clinical trial
- A correlational study
- A true experiment with random assignment
- A case study
Correct answer: A correlational study
A correlational study is correct. When the goal is to assess the strength and direction of a naturally occurring relationship between two measured variables without manipulating them, a correlational method is appropriate. A true experiment requires manipulating an independent variable, which is not being done here.
- In a 2 x 2 study, researchers vary both the difficulty of a task (easy versus hard) and the presence of an audience (alone versus observed) to see whether the effect of an audience depends on task difficulty. The combined influence of the two factors is called what?
- An interaction effect
- A main effect
- A confounding effect
- A ceiling effect
Correct answer: An interaction effect
An interaction effect is correct. An interaction occurs when the effect of one independent variable on the outcome differs depending on the level of another independent variable, which is precisely what a factorial design is built to detect. A main effect, by contrast, is the overall effect of a single factor averaged across the levels of the other.
- A researcher wants to track the same group of individuals from age 5 to age 25 to observe how their vocabulary develops over time. Which research design does this describe?
- A case-control design
- A longitudinal design
- A cross-sectional design
- A correlational survey
Correct answer: A longitudinal design
A longitudinal design is correct. A longitudinal study follows the same participants across an extended period, allowing researchers to observe developmental change within individuals over time. A cross-sectional design instead compares different age groups measured at a single point in time.
- A clinical trial reports a statistically significant difference between two pain treatments with p = 0.001, but the average pain reduction differs by only one-tenth of a point on a 100-point scale. What does this illustrate?
- The result must be due to a Type I error
- The sample size was too small to trust the finding
- The effect size is necessarily very large
- Statistical significance does not guarantee practical or clinical significance
Correct answer: Statistical significance does not guarantee practical or clinical significance
Statistical significance does not guarantee practical or clinical significance is correct. A very small p value indicates the difference is unlikely due to chance, but with large samples even trivial differences can reach significance; a one-tenth-point change has negligible real-world meaning. Researchers therefore report effect sizes alongside p values to convey magnitude.
- A researcher computes a correlation of r = -0.90 between hours spent on social media and self-reported sleep quality. What is the best interpretation of this coefficient?
- No relationship because the value is below zero
- That social media use causes poor sleep
- A strong negative linear relationship: as one variable rises, the other tends to fall
- A weak relationship because the sign is negative
Correct answer: A strong negative linear relationship: as one variable rises, the other tends to fall
A strong negative linear relationship is correct. The negative sign indicates that as one variable increases the other tends to decrease, and the absolute value of 0.90 indicates the relationship is strong. The sign reflects only direction, not weakness, and a correlation cannot establish causation.
- A survey on a sensitive topic asks people whether they recycle, and respondents report recycling far more than landfill data suggest. This discrepancy most likely reflects which threat to validity?
- Social desirability bias
- Inter-rater unreliability
- A ceiling effect
- Random sampling error
Correct answer: Social desirability bias
Social desirability bias is correct. Social desirability bias is the tendency for respondents to answer questions in a way that presents them favorably, overreporting approved behaviors and underreporting disapproved ones. This is especially common with sensitive or socially evaluated topics, distorting self-report data.
- To rule out alternative explanations and isolate the effect of an independent variable, an experimenter ensures that the treatment and comparison groups are treated identically except for the manipulation itself. This practice protects mainly which type of validity?
- External validity
- Internal validity
- Face validity
- Predictive validity
Correct answer: Internal validity
Internal validity is correct. Internal validity concerns whether the study can support a confident cause-and-effect conclusion, which requires eliminating confounds so the only systematic difference between groups is the independent variable. External validity, by contrast, concerns generalizing the findings beyond the study.
- A test developer wants a single number summarizing how consistently a 20-item self-esteem scale's items measure the same underlying trait in one administration. Which statistic is most appropriate?
- Cronbach's alpha
- A Pearson correlation between two raters
- A p value
- A test-retest correlation
Correct answer: Cronbach's alpha
Cronbach's alpha is correct. Cronbach's alpha is a coefficient of internal consistency that estimates how closely related a set of items are as a group within a single test administration. Test-retest correlations index stability over time, and rater correlations index inter-observer agreement, neither of which is internal consistency.
- In an experiment, participants who guess the hypothesis and then alter their behavior to fit what they think the researcher wants are exhibiting what?
- Regression to the mean
- Sampling bias
- Demand characteristics
- The placebo effect
Correct answer: Demand characteristics
Demand characteristics are correct. Demand characteristics are cues in a study that lead participants to infer its purpose and adjust their behavior accordingly, which can bias results independent of the actual manipulation. Researchers minimize them with techniques such as deception, blinding, or unobtrusive measurement.
- A researcher statistically combines effect sizes from 40 separate studies on the same intervention to estimate the overall magnitude of its effect. What is this technique called?
- A double-blind trial
- A factor analysis
- A longitudinal study
- A meta-analysis
Correct answer: A meta-analysis
A meta-analysis is correct. A meta-analysis quantitatively pools the results of many independent studies to produce a more precise and generalizable estimate of an effect than any single study provides. It differs from a narrative literature review by combining the numerical data statistically.
- On an easy quiz where nearly every student scores at or near the maximum, scores cluster at the top and the test cannot distinguish the strongest students from the average ones. What is this measurement problem called?
- Regression to the mean
- A floor effect
- Restriction of range due to attrition
- A ceiling effect
Correct answer: A ceiling effect
A ceiling effect is correct. A ceiling effect occurs when a task or measure is so easy that most scores bunch near the maximum, leaving no room to detect differences among high performers. A floor effect is the mirror image, with scores bunching near the minimum on an overly difficult measure.
- A researcher cannot ethically or practically assign people to smoke versus not smoke, so they compare existing smokers and nonsmokers on lung health. Because group membership was not randomly assigned, what kind of design is this?
- A naturalistic observation
- A quasi-experimental design
- A true experimental design
- A double-blind randomized trial
Correct answer: A quasi-experimental design
A quasi-experimental design is correct. A quasi-experiment compares pre-existing groups when random assignment to conditions is impossible or unethical, so it lacks the control of a true experiment. Without random assignment, confounding variables may differ systematically between groups, weakening causal conclusions.
- A researcher wants to summarize the typical value of a positively skewed income distribution containing a few extremely high earners. Which measure of central tendency best represents the typical case?
- The median
- The standard deviation
- The range
- The mean
Correct answer: The median
The median is correct. The median is the middle value when data are ordered and is unaffected by extreme scores, making it the preferred measure of central tendency for skewed distributions such as income. The mean is dragged toward the high outliers and would overstate the typical income.
