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. How is binge-eating disorder different from bulimia?

A. Typically eat much smaller portions before purging the food.
B. Do not typically purge the food they eat.
C. Only purge their food after several binge sessions.
D. Often resort to anorexic methods to rid themselves of the food they have eaten.

Correct answer: B

Rationale: The correct answer is B because individuals with binge-eating disorder do not typically engage in purging behavior, unlike those with bulimia. Choice A is incorrect as individuals with binge-eating disorder do not purge the food they eat, so they do not eat smaller portions before doing so. Choice C is incorrect as they do not purge their food after several binge sessions. Choice D is incorrect as individuals with binge-eating disorder do not resort to anorexic methods to rid themselves of the food they have eaten.

3. How does genetic predisposition influence mental health?

A. Genetic predisposition guarantees the development of mental disorders.
B. Genetic predisposition plays a role but is not the sole determinant of mental health.
C. Genetic predisposition does not influence mental health.
D. Genetic predisposition determines mental health without exception.

Correct answer: B

Rationale: Genetic predisposition indeed plays a significant role in influencing mental health by increasing the risk of developing certain disorders. However, it is crucial to note that it is not the sole determinant. Mental health is also influenced by various environmental factors, lifestyle choices, and individual experiences. Option A is incorrect because genetic predisposition does not guarantee the development of mental disorders; it only predisposes individuals to a higher risk. Option C is incorrect as genetic predisposition does have an influence on mental health. Option D is incorrect because mental health is a complex interplay of genetic, environmental, and other factors.

4. Skinner would agree with all the following statements except:

A. All behavior is governed by external consequences.
B. Individuals have free will.
C. Organisms tend to repeat responses that lead to positive outcomes.
D. Organisms tend not to repeat responses that lead to neutral or negative outcomes.

Correct answer: B

Rationale: Skinner's behaviorist perspective emphasized that behavior is influenced by external factors and reinforcement, rather than individual free will. Therefore, Skinner would not agree with the statement that individuals have free will. Choices A, C, and D align with Skinner's beliefs as he believed that behavior is shaped by external consequences, organisms tend to repeat behaviors leading to positive outcomes, and organisms tend to avoid behaviors leading to neutral or negative outcomes.

5. Distinguish between assimilation and accommodation.

A. Assimilation refers to adjusting our mental frameworks to incorporate new information.
B. Assimilation is when new experiences are interpreted in terms of existing schemas.
C. Assimilation is adapting our behaviors to match societal norms.
D. Assimilation and accommodation are unrelated to cognitive development.

Correct answer: B

Rationale: The correct answer is B. Assimilation is when new experiences are interpreted in terms of existing schemas, meaning individuals try to fit new information into their pre-existing understanding of the world. Accommodation, on the other hand, involves adjusting our schemas to fit new information, which means changing our existing mental frameworks when new information doesn't fit. Choice A is incorrect because it describes accommodation rather than assimilation. Choice C is incorrect as it confuses assimilation with social adaptation. Choice D is incorrect as assimilation and accommodation are fundamental processes in cognitive development, as described by Piaget.
