Correct Answer: C

Rationale: The correct statement is C: 'Changes in brain function appear to play a role in many psychiatric disorders.' This statement is accurate as research suggests that alterations in brain function are associated with various psychiatric disorders. Option A is incorrect because while brain damage can contribute to some psychiatric conditions, it is not always the primary cause. Option B is incorrect as brain damage typically increases the risk of developing psychiatric disorders. Option D is incorrect because while brain development can be influenced by experiences, it does not always decrease the risk of psychiatric conditions.

Correct Answer: C

Rationale: Cross-cultural research on stress demonstrates that responses to stress vary cross-culturally. Choice A is incorrect because depression being a common response in all countries studied is not supported by cross-cultural research findings. Choice B is incorrect as it generalizes that stress rarely leads to illness in non-Western cultures, which is not universally true. Choice D is incorrect as culture-specific reactions can indeed respond to alterations in the environment, as observed in various cross-cultural studies.

Correct Answer: B

Rationale: The correct answer is B: 'sufficient cause; necessary cause.' A sufficient cause will inevitably produce the disorder, but it is not the only factor. In this case, having the gene for Parkinson's disease is a sufficient cause, meaning it alone can lead to the development of the disease. However, it is not a necessary cause because Parkinson's disease can still develop without the presence of this gene. Choices A, C, and D are incorrect because they do not accurately describe the relationship between the gene and the development of Parkinson's disease as depicted in the question.

Correct Answer: B

Rationale: Neural plasticity allows the brain to recover and reorganize after injuries. It is the brain's ability to adapt and change, forming new connections or reorganizing existing ones to compensate for damage. Choice A is incorrect as neural plasticity enables recovery. Choice C is incorrect as neural plasticity involves the brain's capacity to change. Choice D is incorrect as neural plasticity is a well-established phenomenon in neuroscience.

Correct Answer: A

Rationale: In Japanese culture, a securely attached child is described as dependent and emotionally restrained. This means that the child relies on their caregiver for support and is able to control their emotions, expressing their feelings in a more subtle and indirect manner. Choice B is incorrect as it describes independence, which is not characteristic of a securely attached child in Japanese culture. Choice C is also incorrect as it describes emotional lability and expressing feelings aggressively, which are not typical of securely attached children. Choice D is incorrect as it combines independence with emotional restraint, which does not align with the characteristics of a securely attached child in Japanese culture.
