1. Distinguish between necessary, sufficient, and contributory causes of abnormal behavior.

• A. Necessary causes are required for a disorder to develop but do not guarantee it.
• B. Sufficient causes guarantee a disorder will develop, but they are not required.
• C. Contributory causes increase the likelihood of a disorder but are neither necessary nor sufficient.
• D. Contributory causes are conditions that guarantee the occurrence of a disorder.

Correct answer: A

Rationale: In understanding abnormal behavior, it is crucial to differentiate between necessary, sufficient, and contributory causes. Necessary causes are those that are required for a disorder to develop, meaning that without them, the disorder would not occur. However, their presence does not guarantee the occurrence of the disorder. Sufficient causes, on the other hand, are those that alone can guarantee the development of a disorder, but they are not the only factors that can lead to it. Contributory causes are factors that increase the likelihood of a disorder but are not essential on their own nor do they guarantee the disorder. Therefore, choice A is the correct answer as it accurately describes the role of necessary causes in the development of abnormal behavior. Choices B, C, and D are incorrect as they misrepresent the definitions and roles of sufficient and contributory causes in causing abnormal behavior.

2. How do socioeconomic factors influence mental health?

• A. Socioeconomic factors have no impact on mental health.
• B. Socioeconomic factors are the primary determinants of mental health.
• C. Socioeconomic factors are irrelevant to mental health.
• D. Socioeconomic factors can exacerbate but not cause mental health issues.

Correct answer: B

Rationale: Socioeconomic factors are indeed primary determinants of mental health. These factors influence mental health by impacting access to resources, stress levels, and overall well-being. Choice A is incorrect as socioeconomic factors do have a significant impact on mental health. Choice C is incorrect as socioeconomic factors play a crucial role in mental health outcomes. Choice D is incorrect as socioeconomic factors can both exacerbate and cause mental health issues.

3. 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.

4. When examining heredity, mental disorders are almost always ________

• A. influenced by one particular gene.
• B. influenced by multiple genes.
• C. influenced by recessive genes.
• D. not influenced by genes.

Correct answer: B

Rationale: When examining heredity, mental disorders are influenced by multiple genes. Mental disorders are complex conditions that typically result from a combination of genetic, environmental, and other factors. While genetics play a significant role in predisposing individuals to mental disorders, it is rare for a single gene to be solely responsible for a mental disorder. Therefore, choice B is correct. Choices A, C, and D are incorrect because mental disorders are not usually influenced by one particular gene, recessive genes specifically, or not influenced by genes at all.

5. If having a gene for Parkinson's disease guarantees that Parkinson's disease will develop, the gene is a ________.

• A. risk factor
• B. necessary cause
• C. sufficient cause
• D. contributory cause

Correct answer: B

Rationale: The correct answer is B: necessary cause. A necessary cause is an essential factor for the disorder to occur. In this scenario, if having a gene for Parkinson's disease guarantees the development of the disease, then the gene is a necessary cause. Choice A, 'risk factor,' implies an increased likelihood of developing the disease but does not indicate certainty. Choice C, 'sufficient cause,' indicates that the gene alone can bring about the disease, which is not necessarily true in this context. Choice D, 'contributory cause,' suggests that the gene plays a part in causing the disease but is not essential for its development.
