Psychology 2301 Exam 1

Correct Answer: B

Rationale: The correct answer is B: 'Genes play a role in most mental disorders.' This statement is true as genes do play a significant role in the development of various mental disorders. Choice A is incorrect because most behavioral disorders are influenced by a combination of genetic, environmental, and other factors, not exclusively genes. Choice C is incorrect as genes do affect biochemical processes. Choice D is incorrect because the expression of genes in an individual can be influenced by experiences and environmental factors, a concept known as gene-environment interaction.

Correct Answer: B

Rationale: A culture-bound disorder is a condition that is specific to a particular culture or group of cultures and is not universally recognized or experienced across different cultures. Choice A is incorrect because a culture-bound disorder is not seen universally across all cultures. Choice C is incorrect because it does not necessarily have to only affect children. Choice D is incorrect as a culture-bound disorder is not exclusively found within certain age groups, but rather tied to specific cultures.

Correct Answer: A

Rationale: A diathesis is indeed the correct term for a predisposition toward developing a disorder. A diathesis refers to an underlying vulnerability or predisposition to a particular condition. Choice B, 'comorbidity,' refers to the presence of two or more disorders in the same individual. Choice C, 'genotype,' relates to an individual's genetic makeup. Choice D, 'phenotype,' refers to the observable characteristics of an organism resulting from the interaction of its genotype with the environment. Therefore, A is the most appropriate term for describing a predisposition toward developing a disorder.

Correct Answer: B

Rationale: The correct answer is B because most behaviors are influenced by the interaction of multiple genes and the environment. Choice A is incorrect because it suggests that researching the effects of the environment and genes is easy, which is not the case. Choice C is incorrect as it focuses on a specific method (twin studies) rather than the broader concept of gene-environment interaction. Choice D is incorrect as the statement implies a high level of understanding that contradicts the idea that genetic influences on behavior may never be fully understood.
