1. Which of the following is a common criticism against Piaget's theory of cognitive development?

• A. The sequence of stages is not fixed.
• B. Research has not supported the existence of the preoperational stage.
• C. Piaget put a heavy emphasis on the environment, ignoring the importance of mental processes.
• D. Children develop abilities earlier than Piaget theorized.

Correct answer: D

Rationale: The correct answer is D because one common criticism of Piaget's theory is that children often acquire cognitive abilities earlier than Piaget proposed. This criticism suggests that Piaget's stages might not be as fixed or rigid as he believed. Choices A, B, and C are incorrect: A is a characteristic of Piaget's theory; B is not a common criticism, as research generally supports the existence of Piaget's stages; and C is inaccurate, as Piaget actually emphasized the importance of mental processes in cognitive development.

2. What are some common methods used to study genetic influences on behavior?

• A. Genetic influences are studied only through twin studies.
• B. Common methods include twin studies, adoption studies, and gene mapping.
• C. Genetic influences on behavior are only studied through family history.
• D. Genetic influences on behavior are not well understood.

Correct answer: B

Rationale: Common methods used to study genetic influences on behavior include twin studies, adoption studies, and gene mapping. Twin studies help to compare the similarities between identical and fraternal twins to estimate the heritability of a trait. Adoption studies look at the similarities between adopted children and their biological and adoptive parents to determine genetic influences. Gene mapping involves identifying specific genes associated with certain behaviors. Choices A, C, and D are incorrect because genetic influences on behavior are not solely studied through twin studies or family history, and while the understanding of genetic influences may vary, there are established methods to study them.

3. An elementary school principal wants to know the best predictors of juvenile delinquency and dropping out of school in high school so she can provide preventive interventions. Your best advice is ________.

• A. Look for kids who are very popular because they are class clowns.
• B. Silent, depressed, loners tend to be dropouts because they are often depressed.
• C. There is no way to predict juvenile delinquency as early as elementary school.
• D. The best predictor is aggression toward peers, which leads to peer rejection.

Correct answer: D

Rationale: The best advice is to look for aggression toward peers as the best predictor of juvenile delinquency and dropping out of school. Option A is incorrect because being popular or a class clown doesn't necessarily indicate delinquency. Option B is incorrect as not all silent, depressed loners end up as dropouts. Option C is incorrect as research shows that early signs of aggression can predict future delinquent behavior and school dropout rates, making it feasible to intervene early.

4. How does the concept of neural plasticity relate to recovery from brain injuries?

• A. Neural plasticity means the brain cannot recover from injuries.
• B. Neural plasticity allows the brain to recover and reorganize after injuries.
• C. Neural plasticity refers to the brain's inability to change after injury.
• D. Neural plasticity is a myth.

Correct answer: B

Rationale: Neural plasticity allows the brain to recover and reorganize after injuries. It is the brain's ability to adapt and change, forming new connections or reorganizing existing ones to compensate for damage. Choice A is incorrect as neural plasticity enables recovery. Choice C is incorrect as neural plasticity involves the brain's capacity to change. Choice D is incorrect as neural plasticity is a well-established phenomenon in neuroscience.

5. 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, mental disorders are influenced by multiple genes. Mental disorders are complex conditions that typically result from a combination of genetic, environmental, and other factors. While genetics play a significant role in predisposing individuals to mental disorders, it is rare for a single gene to be solely responsible for a mental disorder. Therefore, choice B is correct. Choices A, C, and D are incorrect because mental disorders are not usually influenced by one particular gene, recessive genes specifically, or not influenced by genes at all.
