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. When examining heredity, mental disorders are almost always ________.

A. influenced by one particular gene.
B. influenced by multiple genes.
C. influenced by recessive genes.
D. not influenced by genes.

Correct answer: B

Rationale: When examining heredity and mental disorders, it is important to note that these conditions are influenced by multiple genes working together. Mental disorders are complex traits that arise from the interplay of various genetic and environmental factors. Therefore, choice B, 'influenced by multiple genes,' is the correct answer. Choice A, 'influenced by one particular gene,' is incorrect because mental disorders typically do not result from the action of a single gene. Choice C, 'influenced by recessive genes,' is incorrect as it oversimplifies the genetic basis of mental disorders. Choice D, 'not influenced by genes,' is also incorrect as genes play a significant role in the development of mental disorders.

3. One key issue in the study of human development is the continuity-discontinuity issue. The discontinuity side posits that development is characterized by change in type or kind. These are known as ____.

A. Qualitative change
B. Quantitative change
C. Maturation
D. Multidirectional development

Correct answer: A

Rationale: The correct answer is A: Qualitative change. Qualitative change aligns with the discontinuity view by involving changes in type or kind. This contrasts with quantitative change (B), which is about changes in amount or quantity. Maturation (C) refers to the process of becoming fully developed in a particular way, and multidirectional development (D) emphasizes that development involves both gains and losses, not specifically focusing on changes in type or kind.

4. What does ethnography refer to?

A. A detailed description of a single culture or context
B. Corrupted by original sin
C. The product of evolution
D. A blank slate

Correct answer: A

Rationale: Ethnography refers to a detailed description of a single culture or context. It involves the systematic study and recording of human cultures, including customs, behaviors, and social structures. Choice B, 'Corrupted by original sin,' is incorrect as it does not relate to ethnography. Choice C, 'The product of evolution,' is incorrect as it does not define ethnography. Choice D, 'A blank slate,' is incorrect as it does not describe the practice of ethnography.

5. If a pair of monozygotic twins raised in the same environment end up being different from one another (e.g., interests, hobbies, etc.), it is highly likely due to:

A. Cephalocaudal pattern
B. Proximodistal pattern
C. Cephamodistal pattern
D. Gene-environment correlation

Correct answer: B

Rationale: The correct answer is B: Proximodistal pattern. Differences between monozygotic twins raised in the same environment are likely due to non-shared environmental influences, which lead to differences in interests, hobbies, and other individual characteristics. Choices A, C, and D are incorrect. Cephalocaudal pattern refers to the principle of development from head to toe, not relevant in explaining differences between twins. Cephamodistal pattern is not a recognized developmental term. Gene-environment correlation does not directly explain the differences between identical twins raised in the same environment.
