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. Which of the following perspectives focuses on social determinants of behavior?

• A. The attachment perspective
• B. The interpersonal perspective
• C. The humanistic perspective
• D. The existential perspective

Correct answer: B

Rationale: The interpersonal perspective focuses on social determinants of behavior, emphasizing the impact of social interactions, relationships, and communication on an individual's behavior. This perspective looks at how people's behavior is influenced by their interactions with others and the social environment. Choices A, C, and D are incorrect because they do not primarily focus on social determinants of behavior. The attachment perspective is concerned with emotional bonds between individuals, the humanistic perspective emphasizes personal growth and self-fulfillment, and the existential perspective focuses on individual freedom and responsibility in creating meaning in life.

3. 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.

4. Normal human cells have ________

• A. twenty-two chromosome pairs and one pair of sex chromosomes.
• B. twenty-one trisomy chromosome pairs, one autosomal pair, and one pair of sex chromosomes.
• C. twenty-one chromosome pairs and two trisomy chromosome pairs.
• D. twenty-three chromosome pairs.

Correct answer: A

Rationale: Normal human cells have twenty-two chromosome pairs and one pair of sex chromosomes. This is the correct answer as it accurately describes the typical chromosome count in human cells. Choice B is incorrect because it mentions 'twenty-one trisomy chromosome pairs,' which is not characteristic of normal cells. Choice C is incorrect as it suggests having 'two trisomy chromosome pairs,' which is abnormal. Choice D is incorrect as it states 'twenty-three chromosome pairs,' which is not the standard count in normal human cells.

5. A predisposition toward developing a disorder is termed a __________ .

• A. Diathesis
• B. Risk factor
• C. Sufficient cause
• D. Diathesis

Correct answer: A

Rationale: A predisposition toward developing a disorder is termed a diathesis. In this context, diathesis refers to an individual's susceptibility or predisposition to developing a disorder. A diathesis is not the same as a risk factor or a sufficient cause. A risk factor is a variable that increases the likelihood of developing a disorder but is not a predisposition itself. A sufficient cause is a factor that can produce the disorder on its own, not just a predisposition.
