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. What does the genetic study of identical twins reared apart help to clarify?

A. Differences in brain function
B. Genetic influence on behavior
C. Interaction between genetics and environment
D. The role of environmental factors alone

Correct answer: C

Rationale: The correct answer is C: 'Interaction between genetics and environment.' The genetic study of identical twins reared apart helps in understanding how both genetics and environment play a role in shaping an individual's traits and behaviors. This type of study allows researchers to tease apart the effects of genetic inheritance from those of environmental influences. Choices A, B, and D are incorrect because the study of identical twins reared apart specifically focuses on the interplay between genetics and environment, rather than solely on differences in brain function, genetic influence on behavior, or the role of environmental factors alone.

3. William James, who was a pioneer in the development of functionalism, was most heavily influenced by?

A. Charles Darwin.
B. Sigmund Freud.
C. John Watson.
D. B.F. Skinner.

Correct answer: A

Rationale: William James was heavily influenced by Charles Darwin's theory of evolution, which shaped his functionalist views on psychology. This influence is evident in James's emphasis on adaptation, survival, and the functional purposes of behavior. Choice B, Sigmund Freud, is incorrect because Freud's psychoanalytic theory focused on unconscious processes and childhood experiences, which differ significantly from James's functionalism. Choice C, John Watson, is incorrect as Watson was a behaviorist who emphasized observable behavior and rejected mental processes, which contrasts with James's focus on mental processes. Choice D, B.F. Skinner, is also incorrect as Skinner was a behaviorist known for his work on operant conditioning, which is not directly aligned with James's functionalist perspective.

4. What does the diathesis-stress model entail?

A. The diathesis-stress model suggests that stress alone is sufficient to cause a mental disorder.
B. The diathesis-stress model involves a combination of genetic vulnerability and environmental stressors.
C. The diathesis-stress model suggests that genetic factors alone cause mental disorders.
D. The diathesis-stress model suggests that stressors in the environment do not affect the onset of mental disorders.

Correct answer: B

Rationale: The diathesis-stress model proposes that mental disorders develop from a combination of genetic vulnerability (the diathesis) and environmental stressors. Choice A is incorrect because it states that stress alone can cause mental disorders, which is not in line with the model. Choice C is incorrect as it simplifies the model to genetic factors alone causing mental disorders. Choice D is incorrect as it suggests that environmental stressors do not play a role in the onset of mental disorders, which contradicts the essence of the diathesis-stress model.

5. Which theoretical viewpoint is most closely associated with Carl Rogers and Abraham Maslow?

A. Cognitive approach.
B. Humanism.
C. Structuralism.
D. Biological approach.

Correct answer: B

Rationale: The correct answer is B: Humanism. Humanism, associated with Carl Rogers and Abraham Maslow, emphasizes personal growth and self-actualization. The cognitive approach (choice A) focuses on mental processes such as thinking and memory, not specifically associated with Rogers and Maslow. Structuralism (choice C) is a historical school of psychology that aimed to identify the structures of consciousness, not linked to Rogers and Maslow. The biological approach (choice D) emphasizes the influence of biology on behavior, also not directly associated with Rogers and Maslow.
