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 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.

3. Why is it difficult to determine the nature of the relationship between divorce and the psychological functioning of family members?

• A. Cause and effect cannot be determined as preexisting behavioral abnormalities in either the parents or the children may make divorce more likely.
• B. The findings have been too inconsistent to draw any conclusions.
• C. While the effects of divorce are negative on children, the effects on the spouses are generally positive.
• D. Due to modern acceptance of divorce, there has been an ongoing decrease in the negative effects of divorce.

Correct answer: A

Rationale: The correct answer is A because it highlights a crucial factor that makes it challenging to establish a clear cause and effect relationship between divorce and the psychological functioning of family members. Preexisting behavioral abnormalities in either the parents or the children may influence both the likelihood of divorce and the psychological functioning of family members. Choice B is incorrect as it generalizes the findings without specifying the key issue of preexisting conditions. Choice C is incorrect as it oversimplifies the effects of divorce on family members. Choice D is incorrect as it presents a broad statement without addressing the complexities involved in determining the effects of divorce.

4. What neurotransmitter was first believed to be the cause of schizophrenia?

• A. GABA
• B. Serotonin
• C. Epinephrine
• D. Dopamine

Correct answer: D

Rationale: The correct answer is Dopamine. Dopamine was initially thought to be the primary cause of schizophrenia. This neurotransmitter hypothesis was based on the observation that drugs that increase dopamine activity can worsen symptoms of schizophrenia, while drugs that decrease dopamine activity can improve symptoms. Choices A, B, and C are incorrect because GABA, serotonin, and epinephrine were not the neurotransmitters initially believed to be the cause of schizophrenia.

5. 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.
