1. Which of the following is not a common method for studying genetic influences?

• A. The study of specific gene defects
• B. Twin studies
• C. Adoption studies
• D. Family history (pedigree) studies

Correct answer: A

Rationale: The correct answer is A. Studying specific gene defects is not a common method for investigating genetic influences. Choices B, C, and D are common methods used in genetic research. Twin studies help determine the heritability of traits, adoption studies compare similarities between adopted individuals and their adoptive families versus biological families, and family history studies track the inheritance patterns of traits within families.

2. What is the significance of early intervention in preventing mental disorders?

• A. Early intervention has no significant impact on preventing mental disorders.
• B. Early intervention is critical in reducing the risk of developing mental disorders.
• C. Early intervention can sometimes exacerbate mental disorders.
• D. Early intervention is only effective in severe cases.

Correct answer: B

Rationale: Early intervention is crucial in preventing or mitigating the development of mental disorders by addressing issues before they fully develop. Choice A is incorrect because early intervention plays a significant role in preventing mental disorders. Choice C is incorrect as early intervention aims to improve mental health outcomes. Choice D is incorrect as early intervention is effective across various stages of mental health conditions, not just in severe cases.

3. What is object-relations theory?

• A. It is the theory that focuses on observable behaviors only.
• B. It is a newer psychodynamic theory focusing on how individuals interact with others and their internalized relationships.
• C. It is the theory that emphasizes the importance of cognitive processes in shaping behavior.
• D. It is a cognitive-behavioral theory focused on changing maladaptive thought patterns.

Correct answer: B

Rationale: Object-relations theory is a psychodynamic theory that focuses on how individuals interact with others and their internalized relationships. Choice A is incorrect because object-relations theory goes beyond observable behaviors to explore internalized relationships. Choice C is incorrect because object-relations theory does not primarily emphasize cognitive processes. Choice D is incorrect because object-relations theory is not a cognitive-behavioral theory focused on changing thought patterns.

4. Which neurotransmitter is reduced in both the manic and depressive phases of bipolar disorder?

• A. Acetylcholine
• B. Dopamine
• C. Norepinephrine
• D. Serotonin

Correct answer: D

Rationale: The correct answer is D, Serotonin. Serotonin levels are reduced during both the manic and depressive phases of bipolar disorder. Acetylcholine (choice A) is not typically linked to bipolar disorder. Dopamine (choice B) and norepinephrine (choice C) are more commonly associated with conditions like schizophrenia and depression, respectively, rather than bipolar disorder. Therefore, they are not the neurotransmitters reduced in both manic and depressive phases of bipolar disorder.

5. Nearly all adults who were children living in Saigon when the U.S. armed forces left Vietnam in 1975 report that their lives were changed by those events. This exemplifies which of the following?

• A. Normative age-graded influence
• B. Social clock
• C. Critical period
• D. Sensitive period

Correct answer: C

Rationale: The correct answer is C. This scenario exemplifies a critical period in development. Critical periods are specific times in an individual's life when certain events have a profound impact on their development. In this case, the events surrounding the departure of the U.S. armed forces from Saigon in 1975 had a lasting influence on the children living there at that time. Choices A, B, and D are incorrect. Normative age-graded influence refers to events that are common to people of a particular age group, the social clock relates to the culturally preferred timing of social events, and a sensitive period is a time when an individual is more susceptible to environmental influences but does not result in lifelong consequences as with critical periods.
