1. The ______________ perspective in psychology takes into account biological, sociological, and psychological factors associated with a person's behaviors.

• A. Behavioral
• B. Cognitive-behavioral
• C. Psychodynamic
• D. Biopsychosocial

Correct answer: D

Rationale: The biopsychosocial perspective is the correct answer as it considers biological, sociological, and psychological factors associated with a person's behaviors. This perspective emphasizes the interconnection between these factors in understanding human behavior. Choice A, Behavioral perspective, focuses primarily on observable behaviors and how they are influenced by the environment. Choice B, Cognitive-behavioral perspective, combines elements of cognitive and behavioral theories to understand behavior but does not encompass sociological factors. Choice C, Psychodynamic perspective, emphasizes unconscious processes and early childhood experiences as determinants of behavior, neglecting the sociological aspect.

2. 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.

3. How does stress impact brain function?

• A. Stress has no effect on brain function.
• B. Stress can lead to changes in brain structure and function.
• C. Stress can improve brain function.
• D. Stress has no long-term impact on brain function.

Correct answer: B

Rationale: Stress can lead to changes in brain structure and function, affecting mental health and increasing the risk of disorders. Choice A is incorrect as stress does affect brain function. Choice C is incorrect as stress generally has negative impacts on brain function rather than improving it. Choice D is incorrect because stress can have long-term impacts on brain function through structural and functional changes.

4. Why is it particularly useful to study identical twins who were raised in different environments?

• A. Differences in brain function can be easily identified.
• B. Concordance rates tend to be higher.
• C. It is possible that the genetics of twins who have been separated have changed in ways to explain any differences found.
• D. It is possible that high concordance rates between identical twins reared together are due to their being treated more similarly than nonidentical twins.

Correct answer: D

Rationale: Studying identical twins raised in different environments allows researchers to understand the impact of genetics versus environmental factors on traits. Choice A is incorrect because differences in brain function can be influenced by a variety of factors and not solely by environmental differences. Choice B is incorrect as concordance rates tend to be higher in identical twins reared together due to shared genetics and environment. Choice C is incorrect because genetics do not change due to being raised in different environments.

5. How does genetic predisposition influence mental health?

• A. Genetic predisposition guarantees the development of mental disorders.
• B. Genetic predisposition plays a role but is not the sole determinant of mental health.
• C. Genetic predisposition does not influence mental health.
• D. Genetic predisposition determines mental health without exception.

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.
