1. What role does genetic predisposition play in the development of mental disorders?

Correct answer: B

Rationale: Genetic predisposition plays a significant role in the development of mental disorders, interacting with environmental factors. While genetics can predispose individuals to certain mental disorders, it is not a guarantee that the disorders will develop. Environmental factors, such as lifestyle, upbringing, and traumatic experiences, also play a crucial role in the manifestation of mental health conditions. Choice C is incorrect as genetic predisposition does have relevance in mental health. Choice D is incorrect as genetic predisposition and environmental factors both contribute to the development of mental disorders, neither completely overriding the other.

2. What does the diathesis-stress model entail?

Correct answer: B

Rationale: The diathesis-stress model proposes that mental disorders develop from a combination of genetic vulnerability (the diathesis) and environmental stressors. Choice A is incorrect because it states that stress alone can cause mental disorders, which is not in line with the model. Choice C is incorrect as it simplifies the model to genetic factors alone causing mental disorders. Choice D is incorrect as it suggests that environmental stressors do not play a role in the onset of mental disorders, which contradicts the essence of the diathesis-stress model.

3. Which of the following psychologists would be most likely to stress that each person has a drive to grow and fulfill his or her potential?

Correct answer: D

Rationale: The correct answer is D, Abraham Maslow. He was a leading humanist psychologist who introduced the concept of the hierarchy of needs. Maslow emphasized the human drive for self-actualization, which involves fulfilling one's potential and striving for personal growth. Sigmund Freud (choice A) focused on psychoanalysis and the unconscious mind. B.F. Skinner (choice B) was a behaviorist who studied operant conditioning. G. Stanley Hall (choice C) was a pioneering psychologist in the field of child development.

4. You are taking part in a survey that asks about your attitudes toward physical punishment of children. Even though you believe that spanking is sometimes necessary, you answer that you are opposed to any sort of physical punishment. Which of the following terms best describes why you answered the way you did?

Correct answer: D

Rationale: The correct answer is D, social desirability. Social desirability bias occurs when respondents answer questions in a way they think will be viewed favorably by others, rather than according to their true beliefs. In this scenario, the respondent may feel pressured to provide an answer that aligns with societal norms or expectations, even if it contradicts their personal beliefs. Choices A, B, and C are incorrect. Random responding refers to answering survey questions haphazardly, without consideration. Faking bad is intentionally providing extreme or negative responses. The placebo effect is a phenomenon where a person's belief in a treatment's effectiveness produces a positive outcome, unrelated to the treatment's actual effects.

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

Correct answer: B

Rationale: When examining heredity and mental disorders, it is important to note that these conditions are influenced by multiple genes working together. Mental disorders are complex traits that arise from the interplay of various genetic and environmental factors. Therefore, choice B, 'influenced by multiple genes,' is the correct answer. Choice A, 'influenced by one particular gene,' is incorrect because mental disorders typically do not result from the action of a single gene. Choice C, 'influenced by recessive genes,' is incorrect as it oversimplifies the genetic basis of mental disorders. Choice D, 'not influenced by genes,' is also incorrect as genes play a significant role in the development of mental disorders.
