Correct Answer: B

Rationale: The correct answer is B, Id. In psychodynamic theory, the Id is the component driven by basic, primal instincts, seeking instant gratification without consideration for consequences. It operates on the pleasure principle, aiming to fulfill desires immediately. The Superego, on the other hand, represents the internalized moral standards and ideals, while the Ego mediates between the Id and Superego, balancing impulses with societal norms. The 'Ideal self' is a concept from humanistic psychology related to one's aspirations and goals, not a component in psychodynamic theory. Therefore, choices A, C, and D are incorrect.

Correct Answer: A

Rationale: The correct answer is A, 'etiology.' Etiology specifically deals with the causes or origins of diseases like depression. Choice B, 'epidemiology,' focuses on the patterns, causes, and effects of health and disease conditions in defined populations. Choice C, 'prevalence,' refers to the proportion of a population found to have a condition. Choice D, 'resiliency,' relates to the ability to recover from or adjust to challenges.

Correct Answer: C

Rationale: The correct answer is C: 'Undercontrolled behavior tends to be seen in American children, whereas overcontrolled behavior is seen in Thai children.' This statement is supported by cultural studies and observations. American children are often described as exhibiting undercontrolled behavior, which includes impulsivity and lack of inhibition. On the other hand, Thai children are often described as showing overcontrolled behavior, characterized by restraint and adherence to social norms. Choice A is incorrect because calm behavior is not typically associated with American children. Choice B is incorrect as overcontrolled behavior is not commonly associated with American children. Choice D is incorrect as there are observed differences in behavioral traits between American and Thai children.

Correct Answer: B

Rationale: The diathesis-stress model suggests that both genetic predisposition and environmental stress are necessary for the development of mental disorders, highlighting the interaction between nature and nurture. Choice A is incorrect because the model emphasizes the combined influence of genetic vulnerability and environmental stressors. Choice C is incorrect as the diathesis-stress model remains a valuable framework in understanding mental health. Choice D is incorrect because the model considers both genetic and environmental factors, not solely environmental factors.

Correct Answer: B

Rationale: The correct answer is B. There is a positive correlation between low socioeconomic status and a higher prevalence of abnormal behavior. Individuals with lower socioeconomic status may face more stressors, reduced access to mental health resources, and other challenges that can contribute to a higher prevalence of abnormal behavior. Choice A is incorrect because socioeconomic status does affect the prevalence of abnormal behavior. Choice C is incorrect because higher socioeconomic status is not associated with a lower prevalence of abnormal behavior. Choice D is incorrect as there is a clear relationship between socioeconomic status and the prevalence of abnormal behavior.
