1. What is the result when a single zygote separates into two parts, each developing into a separate individual?

• A. Dizygotic twin
• B. Monozygotic twin
• C. Fraternal twin
• D. Nonidentical twin

Correct answer: B

Rationale: The correct answer is B, Monozygotic twin. A monozygotic twin, also known as an identical twin, is the result when a single zygote splits into two parts, leading to the development of two genetically identical individuals. Choices A, C, and D are incorrect because they do not accurately describe the scenario where a single zygote splits into two parts to form identical twins. Dizygotic twin (Choice A) refers to fraternal twins, which result from two separate eggs fertilized by two different sperm cells. Fraternal twin (Choice C) is another term for dizygotic twins, arising from two separate zygotes. Nonidentical twin (Choice D) is a synonymous term for dizygotic or fraternal twins, indicating that they are not genetically identical.

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. 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.

4. A newspaper article reported a study by a psychologist in which the attitudes of men and women toward traditional sex roles were studied. Most likely, the researcher was?

• A. A cognitive psychologist.
• B. A counseling psychologist.
• C. A developmental psychologist.
• D. A social psychologist.

Correct answer: D

Rationale: The correct answer is D, a social psychologist. Social psychologists focus on how societal factors, including norms and expectations, influence behaviors and attitudes. In this case, studying the attitudes of men and women toward traditional sex roles aligns with the research domain of social psychology. Choices A, B, and C are incorrect because cognitive psychologists focus on mental processes, counseling psychologists on helping individuals with personal and interpersonal issues, and developmental psychologists on human growth and development, respectively, which are not directly related to studying attitudes towards traditional sex roles influenced by societal factors.

5. How did philosopher John Locke characterize the mind of a child?

• A. Innately good
• B. Conscientiousness
• C. Superego-ideal
• D. A blank slate

Correct answer: D

Rationale: Philosopher John Locke characterized the mind of a child as a 'blank slate,' indicating that it is devoid of innate ideas or characteristics. This concept suggests that a child's mind is shaped and developed through experiences and learning rather than having inherent qualities. Choices A, B, and C are incorrect as Locke did not view the mind of a child as innately good, conscientious, or associated with the superego-ideal. Instead, he believed that individuals are born without built-in mental content, emphasizing the importance of environmental influences on cognitive development.
