Q: What is the role of the amygdala in the brain?
A: It is primarily involved in the processing of emotions, particularly fear and pleasure.

authority and submissiveness, demonstrating the impact of situational factors on behavior.
Question 7
Q: What does the term "nature vs. nurture" refer to in psychology?
A: The debate over the relative contributions of genetic inheritance and environmental factors
to human development.
Rationale: This concept explores how much of our behavior, personality, and traits are
shaped by biology (nature) versus our experiences and environment (nurture).
Question 8
Q: What is the primary goal of behaviorism in psychology?
A: To study observable behavior and the ways it can be shaped through reinforcement and

outcomes.

condition due to their expectations of treatment, highlighting the power of the mind in
physical health.
Question 10
Q: Which type of research design allows psychologists to draw conclusions about cause-and-
effect relationships?
A: Experimental research design.
Rationale: Experimental research involves manipulation of variables and control of
extraneous factors, allowing researchers to determine whether changes in one variable cause
changes in another.
Question 11
Q: What is the term for the mental process of organizing and interpreting sensory
information?
A: Perception.
Rationale: Perception involves the brain's interpretation of sensory signals, allowing
individuals to make sense of the world around them.
Question 12
Q: In classical conditioning, what is the unconditioned stimulus (US)?
A: A stimulus that naturally and automatically triggers a response without prior learning.
, Rationale: In Pavlov's experiments, the unconditioned stimulus (e.g., food) elicits an
unconditioned response (e.g., salivation) without any conditioning.

Rationale: Cognitive psychology investigates how people think, learn, remember, and solve
problems, emphasizing the role of mental processes in behavior.
Question 15
Q: What is the difference between intrinsic and extrinsic motivation?
A: Intrinsic motivation comes from within (personal satisfaction), while extrinsic motivation
is driven by external rewards (money, grades).
Rationale: Intrinsic motivation is based on internal satisfaction and interest, while extrinsic
motivation involves external factors that influence behavior.
Question 16
