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. There is experimental evidence showing that consistently being discriminated against may cause a person to ________.

Correct answer: C

Rationale: The correct answer is C: 'have cardiovascular reactivity.' Consistent discrimination can lead to increased cardiovascular reactivity, impacting heart health. Choice A ('be happy') is incorrect because discrimination typically causes distress and negative emotions. Choice B ('be more conscious') is not directly related to the impact of discrimination. Choice D ('have greater intelligence and wisdom') is also unrelated to the physiological response of cardiovascular reactivity caused by discrimination.

3. Skinner would agree with all the following statements except:

Correct answer: B

Rationale: Skinner's behaviorist perspective emphasized that behavior is influenced by external factors and reinforcement, rather than individual free will. Therefore, Skinner would not agree with the statement that individuals have free will. Choices A, C, and D align with Skinner's beliefs as he believed that behavior is shaped by external consequences, organisms tend to repeat behaviors leading to positive outcomes, and organisms tend to avoid behaviors leading to neutral or negative outcomes.

4. How does genetic predisposition influence mental health?

Correct answer: B

Rationale: Genetic predisposition indeed plays a significant role in influencing mental health by increasing the risk of developing certain disorders. However, it is crucial to note that it is not the sole determinant. Mental health is also influenced by various environmental factors, lifestyle choices, and individual experiences. Option A is incorrect because genetic predisposition does not guarantee the development of mental disorders; it only predisposes individuals to a higher risk. Option C is incorrect as genetic predisposition does have an influence on mental health. Option D is incorrect because mental health is a complex interplay of genetic, environmental, and other factors.

5. Cortisol is a hormone that ________.

Correct answer: C

Rationale: Cortisol is a hormone produced by the adrenal gland that mobilizes the body to deal with stress. Therefore, choice C is the correct answer. Choices A and B are incorrect as they inaccurately describe the origin and function of cortisol. Choice D is also incorrect as it describes the action of a different type of substance, not cortisol.
