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.

What is the diathesis-stress model of psychopathology?
- A. The idea that stress is the primary cause of psychopathology.
- B. A model that focuses solely on genetic predispositions.
- C. A theory that involves only environmental factors in the development of disorders.
- D. A person must have both a vulnerability for a disorder and exposure to stressors to develop the disorder.
Correct Answer: D
Rationale: The diathesis-stress model of psychopathology posits that individuals must have a vulnerability or predisposition to a disorder (diathesis) and be exposed to stressful environmental factors for the disorder to manifest. This model emphasizes the interaction between genetic or biological vulnerabilities (diathesis) and environmental stressors. Choice A is incorrect because the model does not suggest that stress is the sole cause of psychopathology. Choice B is incorrect as the model considers both genetic predispositions and environmental stressors. Choice C is incorrect because the diathesis-stress model acknowledges the role of both genetic and environmental factors in the development of disorders.
How does the biopsychosocial model differ from the biomedical model?
- A. The biopsychosocial model focuses solely on the biological aspects of disease.
- B. The biopsychosocial model includes biological, psychological, and social factors, whereas the biomedical model focuses on only biological factors.
- C. The biopsychosocial model is outdated and has been replaced by the biomedical model.
- D. The biopsychosocial model is identical to the biomedical model.
Correct Answer: B
Rationale: The biopsychosocial model differs from the biomedical model by considering biological, psychological, and social factors in understanding health and illness. Choice A is incorrect because the biopsychosocial model does not solely focus on biological aspects. Choice C is incorrect as the biopsychosocial model is not outdated but rather offers a more comprehensive approach. Choice D is incorrect as the two models are distinct in their considerations of factors beyond biology.
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 role does genetic predisposition play in the development of mental disorders?
- A. Genetic predisposition guarantees the development of mental disorders.
- B. Genetic predisposition plays a significant role but is not the only factor in developing mental disorders.
- C. Genetic predisposition is irrelevant in mental health.
- D. Genetic predisposition can be completely overridden by environmental factors.
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.
According to Freud, a person who does not appropriately resolve each psychosexual stage would be _________ at that stage.
- A. defended
- B. fixated
- C. repressed
- D. displaced
Correct Answer: B
Rationale: According to Freud's theory of psychosexual development, if a person does not resolve a particular stage successfully, they become fixated at that stage. This fixation can lead to behavior patterns characteristic of that stage in later life. In this context, 'defended' is incorrect because it does not align with Freud's theory of fixation. 'Repressed' is not the correct choice as it refers to the unconscious suppression of thoughts or desires. 'Displaced' involves redirecting emotions from their original source to a substitute target, which is not the concept Freud associated with unresolved psychosexual stages.
