Psychology 101 Exam 3 Test

1. When examining heredity, mental disorders are almost always ________

A. influenced by one particular gene.
B. influenced by multiple genes.
C. influenced by recessive genes.
D. not influenced by genes.

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.

2. What is the significance of early intervention in preventing mental disorders?

A. Early intervention has no significant impact on preventing mental disorders.
B. Early intervention is critical in reducing the risk of developing mental disorders.
C. Early intervention can sometimes exacerbate mental disorders.
D. Early intervention is only effective in severe cases.

Correct answer: B

Rationale: Early intervention is crucial in preventing or mitigating the development of mental disorders by addressing issues before they fully develop. Choice A is incorrect because early intervention plays a significant role in preventing mental disorders. Choice C is incorrect as early intervention aims to improve mental health outcomes. Choice D is incorrect as early intervention is effective across various stages of mental health conditions, not just in severe cases.

3. What is the biopsychosocial model?

A. A model that integrates biological, psychological, and social factors in understanding mental disorders.
B. A model that emphasizes the interaction between biological and psychological factors, excluding social influences.
C. The biopsychosocial model emphasizes only psychological factors in mental disorders.
D. The biopsychosocial model is a purely biological approach to mental health.

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.

4. How does the concept of neural plasticity relate to recovery from brain injuries?

A. Neural plasticity means the brain cannot recover from injuries.
B. Neural plasticity allows the brain to recover and reorganize after injuries.
C. Neural plasticity refers to the brain's inability to change after injury.
D. Neural plasticity is a myth.

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.

5. Daniel is pretending that one of his blocks is a car. Daniel is exhibiting which function?

A. Abstraction
B. Preoperational
C. Overextension
D. Semiotic

Correct answer: A

Rationale: The correct answer is A: Abstraction. Pretending that a block is a car demonstrates abstraction, where one object is used to represent another. Choice B, Preoperational, refers to Piaget's stage of cognitive development. Choice C, Overextension, involves using a word in a broader context than is appropriate. Choice D, Semiotic, refers to the use of symbols to represent ideas or concepts, which is not directly related to the scenario described in the question.
