1. 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.

2. Which of the following characteristics best describes differences between bulimia nervosa and anorexia nervosa?

• A. Individuals with anorexia nervosa do not have as severe health risks as individuals with bulimia nervosa have.
• B. Individuals with bulimia nervosa may have a normal body weight.
• C. Individuals with anorexia nervosa have been known to binge like those with bulimia nervosa on occasion.
• D. Only those with bulimia nervosa display compensatory behaviors.

Correct answer: B

Rationale: The correct answer is B. Individuals with bulimia nervosa may maintain a normal body weight, while anorexia nervosa is often associated with severe underweight. Choice A is incorrect because individuals with anorexia nervosa actually face severe health risks due to malnutrition, electrolyte imbalances, and other complications. Choice C is incorrect as anorexia nervosa is characterized by restriction of food intake rather than binge eating. Choice D is incorrect as individuals with anorexia nervosa can also display compensatory behaviors such as excessive exercise or fasting.

3. Which of the following explanations for the relationship between SES and abnormal behavior is not supported by the existing data?

• A. Low SES may cause abnormal behavior.
• B. Abnormal behavior is more likely to go untreated in those of low SES.
• C. Recovery from loss of a job may be more difficult for those exhibiting signs of mental illness.
• D. High SES may cause abnormal behavior.

Correct answer: D

Rationale: The correct answer is D because high SES as a cause for abnormal behavior is not supported by existing data. Abnormal behavior is often associated with factors like stress, trauma, genetics, or environmental influences. High SES is not a known cause of abnormal behavior. Choices A, B, and C are more plausible explanations: Low SES may lead to limited access to mental health care, untreated abnormal behavior due to financial constraints, and difficulties in coping with mental health issues after job loss, respectively.

4. Latresha is not hungry, is extremely tired, and doesn't feel like doing much of anything. She often feels that life is just hopeless. These symptoms have been going on for 2 months now. She probably is suffering from which mood disorder?

• A. Generalized anxiety disorder
• B. Bipolar disorder
• C. Major depressive disorder
• D. Obsessive-compulsive disorder

Correct answer: C

Rationale: The correct answer is C, Major Depressive Disorder. Latresha's symptoms of prolonged sadness, fatigue, and lack of interest in activities lasting for 2 months indicate a major depressive episode. Generalized anxiety disorder (A) is characterized by excessive worry and anxiety, not necessarily prolonged sadness. Bipolar disorder (B) involves episodes of both mania and depression, not solely prolonged sadness. Obsessive-compulsive disorder (D) is characterized by obsessions and compulsions, not the symptoms described in the scenario.

5. During which span of months or years is a child particularly responsive to specific forms of experience or influenced by their absence?

• A. Nonnormative influences
• B. Normative age-graded influence
• C. Normative history-graded influence
• D. Sensitive period

Correct answer: D

Rationale: The correct answer is 'Sensitive period.' A sensitive period refers to a specific span of time during development when a child is especially responsive to certain experiences. This period allows for optimal development in specific areas. Nonnormative influences (Choice A) are events that are irregular and unpredictable, while normative age-graded influences (Choice B) are typical events that occur in a similar manner for most people in a specific age group. Normative history-graded influences (Choice C) are events that most people in a specific culture or cohort experience at the same time.
