Psychology 101 Final Exam

1. How does the diathesis-stress model explain the onset of mental disorders?

A. Stress alone is sufficient to cause mental disorders.
B. Both genetic vulnerability and environmental stress are needed to trigger a disorder.
C. Only genetic factors cause mental disorders.
D. Environmental stressors alone can cause mental disorders.

Correct answer: B

Rationale: The diathesis-stress model explains that the onset of mental disorders results from the interaction of genetic vulnerability (diathesis) and environmental stress. Choice A is incorrect because stress alone is not sufficient, according to the model. Choice C is incorrect as it oversimplifies by attributing mental disorders solely to genetic factors. Choice D is incorrect because the model emphasizes the joint contribution of genetic predisposition and environmental stress.

2. In an experiment, the investigators manipulate variables to learn how one affects another.?

A. A data-collection method in which participants respond to questions
B. The entire group that is of interest to a researcher
C. A detailed description of a single culture or context
D. A study that tests a causal hypothesis

Correct answer: D

Rationale: The correct answer is D because in an experimental design, investigators manipulate variables to determine the effect of one on another. This process allows researchers to test causal hypotheses by manipulating one variable while keeping others constant. Choices A, B, and C are incorrect as they do not directly relate to manipulating variables in an experiment.

3. How do defense mechanisms contribute to psychopathology?

A. They do not contribute to psychopathology as they are healthy coping mechanisms.
B. They contribute to psychopathology by allowing individuals to avoid confronting painful realities.
C. Defense mechanisms have no connection to psychopathology.
D. Defense mechanisms are unconscious strategies that can lead to the development of psychopathology.

Correct answer: B

Rationale: The correct answer is B. Defense mechanisms contribute to psychopathology by allowing individuals to avoid confronting painful realities. This avoidance can prevent individuals from dealing with underlying issues, leading to the development or exacerbation of psychopathological conditions. Choice A is incorrect because while defense mechanisms may serve as coping mechanisms, they can also contribute to psychopathology when used excessively or inappropriately. Choice C is incorrect as defense mechanisms are indeed connected to psychopathology. Choice D is incorrect because defense mechanisms, when maladaptive, can contribute to psychopathology rather than being considered healthy coping strategies.

4. Professor Immel believes that behaviors that are predominant in certain species probably serve some adaptive function. Professor Immel's beliefs are most consistent with which perspective?

A. Behavioral perspective.
B. Cognitive perspective.
C. Humanistic perspective.
D. Evolutionary perspective.

Correct answer: D

Rationale: Professor Immel's belief that behaviors in certain species serve an adaptive function aligns with the evolutionary perspective. The evolutionary perspective posits that behaviors have developed over time because they provide an advantage for survival and reproduction. This perspective emphasizes the role of natural selection in shaping behaviors based on their adaptive value. Choices A, B, and C do not specifically address the idea that behaviors have evolved to serve specific functions for survival, making them inconsistent with Professor Immel's beliefs.

5. Who took the position that organisms tend to repeat responses that lead to positive outcomes and tend not to repeat responses that lead to neutral or negative outcomes?

A. Sigmund Freud
B. B.F. Skinner
C. Carl Rogers
D. Abraham Maslow

Correct answer: B

Rationale: The correct answer is B.F. Skinner. Skinner proposed the theory of operant conditioning, where behavior is shaped by its consequences. Positive outcomes increase the likelihood of a behavior being repeated, while neutral or negative outcomes decrease it. Sigmund Freud (choice A) is known for his psychoanalytic theory, Carl Rogers (choice C) for person-centered therapy, and Abraham Maslow (choice D) for the hierarchy of needs.
