How does the diathesis-stress model explain the onset of mental disorders?

Correct Answer: B

Rationale: The diathesis-stress model explains that the onset of mental disorders results from the interaction of genetic vulnerability (diathesis) and environmental stress. Choice A is incorrect because stress alone is not sufficient, according to the model. Choice C is incorrect as it oversimplifies by attributing mental disorders solely to genetic factors. Choice D is incorrect because the model emphasizes the joint contribution of genetic predisposition and environmental stress.

Correct Answer: B

Rationale: Genetic predisposition plays a significant role in the development of mental disorders, interacting with environmental factors. While genetics can predispose individuals to certain mental disorders, it is not a guarantee that the disorders will develop. Environmental factors, such as lifestyle, upbringing, and traumatic experiences, also play a crucial role in the manifestation of mental health conditions. Choice C is incorrect as genetic predisposition does have relevance in mental health. Choice D is incorrect as genetic predisposition and environmental factors both contribute to the development of mental disorders, neither completely overriding the other.

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: 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.
