Correct Answer: A

Rationale: In understanding abnormal behavior, it is crucial to differentiate between necessary, sufficient, and contributory causes. Necessary causes are those that are required for a disorder to develop, meaning that without them, the disorder would not occur. However, their presence does not guarantee the occurrence of the disorder. Sufficient causes, on the other hand, are those that alone can guarantee the development of a disorder, but they are not the only factors that can lead to it. Contributory causes are factors that increase the likelihood of a disorder but are not essential on their own nor do they guarantee the disorder. Therefore, choice A is the correct answer as it accurately describes the role of necessary causes in the development of abnormal behavior. Choices B, C, and D are incorrect as they misrepresent the definitions and roles of sufficient and contributory causes in causing abnormal behavior.

Correct Answer: B

Rationale: When examining heredity, mental disorders are influenced by multiple genes. Mental disorders are complex conditions that typically result from a combination of genetic, environmental, and other factors. While genetics play a significant role in predisposing individuals to mental disorders, it is rare for a single gene to be solely responsible for a mental disorder. Therefore, choice B is correct. Choices A, C, and D are incorrect because mental disorders are not usually influenced by one particular gene, recessive genes specifically, or not influenced by genes at all.

Correct Answer: A

Rationale: Freud believed that anxiety was a primary causal factor in the development of most forms of psychopathology. Anxiety, according to Freud, arises from conflicts within the mind, particularly conflicts between the id, ego, and superego. This unresolved conflict can lead to various psychological issues. While depression can be a symptom of psychopathology, Freud emphasized anxiety as a more foundational element. Unresolved conflicts between the ego and the superego are related to Freud's structural model of the mind but are not the primary causal factor in psychopathology. Fixation in the oral stage is a concept from Freud's psychosexual stages of development and is not directly linked to the causal role in the development of most forms of psychopathology.

Correct Answer: A

Rationale: The biopsychosocial model is a comprehensive approach that considers biological, psychological, and social factors in understanding mental disorders. Choice A is correct because it accurately describes how this model integrates these three factors. Choice B is incorrect as it excludes social influences from the model. Choice C is incorrect because it states that the model only emphasizes psychological factors, which is not true. Choice D is incorrect as it suggests that the model is purely biological, which is also inaccurate.

Correct Answer: B

Rationale: Culture is crucial in understanding the development of psychopathology. It influences beliefs, norms, values, and behaviors, which can significantly impact the manifestation and understanding of psychopathological conditions. Choice A is incorrect because culture does have a substantial impact on psychopathology. Choice C is not as strong as choice B in emphasizing the significance of culture. Choice D is incorrect as culture is one of many factors influencing the onset of psychopathology, not the sole determinant.
