Down syndrome is caused by ________
- A. a chemical imbalance.
- B. a gene on the X chromosome.
- C. possessing an extra X chromosome.
- D. possessing an extra chromosome in chromosome 21.
Correct Answer: D
Rationale: Down syndrome is caused by possessing an extra chromosome in chromosome 21, not a chemical imbalance (choice A), a gene on the X chromosome (choice B), or possessing an extra X chromosome (choice C). The presence of an extra copy of chromosome 21, also known as trisomy 21, leads to the characteristic features and health problems associated with Down syndrome.

What is the significance of the diathesis-stress model in understanding mental disorders?
- A. The diathesis-stress model suggests that stress alone causes mental disorders.
- B. The diathesis-stress model suggests that both genetic predisposition and environmental stress are necessary for the development of mental disorders.
- C. The diathesis-stress model is outdated and irrelevant.
- D. The diathesis-stress model focuses only on environmental factors.
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.
Defense mechanisms ________.
- A. make a person feel more anxious and have more problems, as they begin to act defensively.
- B. are strategies the id uses to try to achieve its desires.
- C. are conscious, intentional attempts to cope effectively with an anxiety-producing event.
- D. help a person feel less anxious, but because they usually work by distorting reality, they are not always adaptive.
Correct Answer: D
Rationale: The correct answer is D because defense mechanisms aim to reduce anxiety but can lead to distortion of reality, making them not always beneficial. Choice A is incorrect as defense mechanisms are meant to reduce anxiety, not increase it. Choice B is incorrect because defense mechanisms are not strategies of the id specifically. Choice C is incorrect as defense mechanisms are often unconscious and not always intentional.
What is the relationship between socioeconomic status and the prevalence of abnormal behavior?
- A. Socioeconomic status does not affect the prevalence of abnormal behavior.
- B. There is a positive correlation between low socioeconomic status and a higher prevalence of abnormal behavior.
- C. Higher socioeconomic status is associated with a lower prevalence of abnormal behavior.
- D. Socioeconomic status and the prevalence of abnormal behavior are unrelated.
Correct Answer: B
Rationale: The correct answer is B. There is a positive correlation between low socioeconomic status and a higher prevalence of abnormal behavior. Individuals with lower socioeconomic status may face more stressors, reduced access to mental health resources, and other challenges that can contribute to a higher prevalence of abnormal behavior. Choice A is incorrect because socioeconomic status does affect the prevalence of abnormal behavior. Choice C is incorrect because higher socioeconomic status is not associated with a lower prevalence of abnormal behavior. Choice D is incorrect as there is a clear relationship between socioeconomic status and the prevalence of abnormal behavior.
While having a gene for Parkinson's disease guarantees that Parkinson's disease will develop, this is not the only factor that can lead to Parkinson's disease. In other words, the presence of the gene is a ________, but not a ________.
- A. risk factor; sufficient cause
- B. sufficient cause; necessary cause
- C. necessary cause; risk factor
- D. contributory cause; sufficient cause
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.
What are protective factors? Give an example of one and explain how it can impact a person's later functioning.
- A. Protective factors are influences that modify a person's response to environmental stressors, making adverse consequences less likely.
- B. An example of a protective factor is having a warm and caring parent, which may lead to resilience.
- C. Protective factors usually lead to resilience, the ability to adapt successfully to stressful circumstances.
- D. Protective factors always prevent the development of psychopathology.
Correct Answer: B
Rationale: Protective factors are influences that modify a person's response to environmental stressors, reducing the likelihood of adverse outcomes. An example of a protective factor is having a warm and caring parent, which can foster resilience in individuals. Resilience allows individuals to adapt successfully to stressful situations. Choice A is incorrect as protective factors do not always prevent adverse consequences but reduce their likelihood. Choice C is incorrect as resilience is the outcome of protective factors, not the other way around. Choice D is incorrect as while protective factors can reduce the risk of psychopathology, they do not always prevent its development.
