1. Which of the following statements about brain dysfunction and psychiatric disorders is correct?

A. Identifiable brain damage is often the cause of psychiatric disorders.
B. Brain damage may decrease the risk of developing a psychiatric condition.
C. Changes in brain function appear to play a role in many psychiatric disorders.
D. Brain development can be altered by experience, always leading to changes in the brain that decrease the risk of developing a psychiatric condition.

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.

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

A. Stress alone is sufficient to cause mental disorders.
B. Both genetic vulnerability and environmental stress are needed to trigger a disorder.
C. Only genetic factors cause mental disorders.
D. Environmental stressors alone can cause 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.

3. Genes ________.

A. determine how a person will behave.
B. cause people to develop mental disorders.
C. determine what characteristics a person will have.
D. determine the range of characteristics a person has.

Correct answer: D

Rationale: Genes determine the range of characteristics a person has. This is the correct answer because genes contribute to a variety of traits and characteristics a person may have, influencing physical attributes, predispositions to certain conditions, and more. Choice A is incorrect because behavior is influenced by a combination of genetic and environmental factors. Choice B is incorrect because mental disorders are complex conditions influenced by various factors beyond just genes. Choice C is incorrect because genes do not solely determine all characteristics a person will have, as environmental factors also play a significant role.

4. What is the biopsychosocial model, and why is it important?

A. A model that integrates biological, psychological, and social factors.
B. A model that focuses solely on biological factors.
C. A model that excludes social factors.
D. A model that focuses solely on psychological factors.

Correct answer: A

Rationale: The biopsychosocial model is a model that integrates biological, psychological, and social factors. It is important because it recognizes the interconnectedness of these factors in influencing an individual's mental health. Option B is incorrect because the biopsychosocial model does not focus solely on biological factors. Option C is incorrect as the model does not exclude social factors. Option D is incorrect as the model does not focus solely on psychological factors.

5. ______________ are conditions that increase the probability of a disorder but are neither necessary nor sufficient to cause it.

A. Risk factors
B. Contributory causes
C. Sufficient causes
D. Protective factors

Correct answer: B

Rationale: The correct term for conditions that increase the probability of a disorder but are neither necessary nor sufficient to cause it is 'Contributory causes.' Risk factors (Choice A) are conditions that increase the likelihood of a negative outcome but do not imply causation. Sufficient causes (Choice C) are conditions that guarantee the occurrence of a disorder by themselves. Protective factors (Choice D) decrease the likelihood of a disorder rather than increasing it.
