Section One: Questions 1–100
,1. In a study on the impact of sleep deprivation on cognitive performance,
researchers manipulate the number of hours participants are allowed to sleep.
In this experiment, what is the independent variable?
A. The cognitive performance of the participants
B. The number of hours of sleep
C. The age of the participants
D. The time of day the test is administered
🟢B
🔴 Explanation: The independent variable is the factor that the researcher
manipulates to observe its effect. In this study, the researchers are directly
manipulating the number of hours of sleep. Cognitive performance (A) is the
dependent variable, the outcome being measured. Age (C) and time of day (D)
are potential confounding variables that would ideally be controlled.
2. The somatic nervous system is responsible for which of the following
actions?
A. Regulating heart rate and digestion
B. Dilating the pupils in low light
C. Controlling voluntary muscle movements
D. Activating the "fight-or-flight" response
🟢C
🔴 Explanation: The somatic nervous system is the division of the peripheral
nervous system that controls voluntary movements by innervating skeletal
muscles. Regulating heart rate (A), pupil dilation (B), and the fight-or-flight
response (D) are all functions of the autonomic nervous system, which operates
involuntarily.
3. According to Erikson's theory of psychosocial development, what is the
primary crisis faced by young adults?
A. Trust vs. Mistrust
B. Identity vs. Role Confusion
,C. Generativity vs. Stagnation
D. Intimacy vs. Isolation
🟢D
🔴 Explanation: Erikson's stage for young adulthood (roughly ages 19-40) is
Intimacy vs. Isolation, where the major challenge is forming intimate, loving
relationships with others. Trust vs. Mistrust (A) is the first stage of infancy. Identity
vs. Role Confusion (B) is the crisis of adolescence. Generativity vs. Stagnation (C) is
the crisis of middle adulthood.
4. Which of the following is a key characteristic of a true experiment?
A. In-depth interviews and case studies
B. Random assignment of participants to conditions
C. Observation of behavior in a natural setting
D. The use of self-report questionnaires
🟢B
🔴 Explanation: Random assignment to different conditions is the hallmark of a
true experiment, allowing researchers to infer cause-and-effect relationships by
controlling for confounding variables. In-depth interviews (A) and naturalistic
observation (C) are methods used in correlational or descriptive research. Self-
report questionnaires (D) can be used in experiments but are not the defining
characteristic.
5. Damage to Broca's area in the brain would most likely result in:
A. Difficulty understanding spoken language
B. An inability to produce fluent speech
C. A loss of visual perception
D. Impaired long-term memory formation
🟢B
🔴 Explanation: Broca's area, typically located in the left frontal lobe, is crucial for
speech production. Damage to this area results in Broca's aphasia, characterized
by halting, effortful speech. Difficulty understanding language (A) is associated
, with Wernicke's area. Visual perception loss (C) is linked to the occipital lobe, and
memory formation impairment (D) is associated with the hippocampus.
6. In classical conditioning, an organism learns to associate:
A. A behavior with a consequence
B. A neutral stimulus with an unconditioned stimulus
C. A response with a reinforcement schedule
D. A behavior with its environmental context
🟢B
🔴 Explanation: Classical conditioning is the process of learning through
association where a previously neutral stimulus (like a bell) is paired with an
unconditioned stimulus (like food) to produce a conditioned response.
Associating behavior with consequence (A) describes operant conditioning.
Response with a reinforcement schedule (C) is a component of operant
conditioning.
7. According to Maslow's hierarchy of needs, which need must be met first
before an individual can focus on self-actualization?
A. Esteem needs
B. Love and belonging needs
C. Safety and security needs
D. Physiological needs
🟢D
🔴 Explanation: Maslow's hierarchy is often depicted as a pyramid, with the most
basic needs at the bottom. Physiological needs (food, water, shelter) are the most
fundamental and must be satisfied before an individual can be motivated by
higher-level needs like safety (C), belonging (B), or self-actualization.
8. A therapist who uses active listening, unconditional positive regard, and
empathy is most likely practicing which type of therapy?
A. Psychoanalysis
B. Cognitive-behavioral therapy (CBT)
