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

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. Freud's psychosexual stage that occurs between the ages of 3 and 5 is the ________ stage.

Correct answer: C

Rationale: Freud's psychosexual stage that occurs between the ages of 3 and 5 is the phallic stage. During this stage, children focus on the genitals and start to identify with the same-sex parent while developing the superego. Choice A, the oral stage, occurs during infancy (0-1 year), where gratification is centered around the mouth. Choice B, the anal stage, occurs between the ages of 1 and 3, focusing on toilet training. Choice D, the genital stage, is the final stage in Freud's theory, occurring from puberty onwards, where the focus is on mature sexual relationships.

3. Why is it particularly useful to study identical twins who were raised in different environments?

Correct answer: D

Rationale: Studying identical twins raised in different environments allows researchers to understand the impact of genetics versus environmental factors on traits. Choice A is incorrect because differences in brain function can be influenced by a variety of factors and not solely by environmental differences. Choice B is incorrect as concordance rates tend to be higher in identical twins reared together due to shared genetics and environment. Choice C is incorrect because genetics do not change due to being raised in different environments.

4. Down syndrome is caused by ________

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.

5. Freud's view of mental disorders was that they were a result of ________.

Correct answer: A

Rationale: Freud believed that mental disorders were a result of unresolved conflicts between the id, ego, and superego. This concept is central to Freud's psychoanalytic theory, where conflicts between these three components of personality lead to psychological distress. Choice B is incorrect because Freud focused more on unconscious conflicts rather than genetic abnormalities. Choice C is incorrect as it refers to later psychodynamic theories rather than Freud's specific view. Choice D is incorrect as Freud's perspective does not emphasize learned behaviors as the primary cause of mental disorders.
