1. Which of the following is not a common method for studying genetic influences?

• A. The study of specific gene defects
• B. Twin studies
• C. Adoption studies
• D. Family history (pedigree) studies

Correct answer: A

Rationale: The correct answer is A. Studying specific gene defects is not a common method for investigating genetic influences. Choices B, C, and D are common methods used in genetic research. Twin studies help determine the heritability of traits, adoption studies compare similarities between adopted individuals and their adoptive families versus biological families, and family history studies track the inheritance patterns of traits within families.

2. What role do genetic predispositions play in the development of mental disorders?

• A. Genetic predispositions solely determine the development of mental disorders.
• B. Genetic predispositions play a role but are not solely responsible for the development of mental disorders.
• C. Genetic predispositions have no influence on mental disorders.
• D. Genetic predispositions guarantee the development of mental disorders.

Correct answer: B

Rationale: Genetic predispositions are indeed a factor in the development of mental disorders, but they are not the sole determining factor. While genetics can predispose individuals to certain conditions, environmental factors, lifestyle choices, and life experiences also play a significant role. Choice A is incorrect because mental disorders are influenced by a combination of genetic and environmental factors. Choice C is incorrect as genetic predispositions do have an impact on mental health. Choice D is incorrect as genetic predispositions do not guarantee the development of mental disorders, as other factors also contribute to their onset.

3. School phobia among kids may be a form of?

• A. Occurs every time when one is in a certain situation
• B. Occurs most of the time when one is in a specific situation
• C. Be unexpected
• D. Expected

Correct answer: C

Rationale: The correct answer is C: 'Be unexpected.' School phobia in children is often associated with separation anxiety disorder, leading to unexpected and intense fear or anxiety about attending school. Choices A and B are incorrect because school phobia does not necessarily occur every time or most of the time when in a specific situation; it is more about the unexpected fear related to attending school. Choice D is also incorrect because school phobia is characterized by an unexpected and overwhelming fear of school, not an expected or anticipated reaction.

4. An inborn trait that is relatively permanent and differentiates one person from another is known as ________.

• A. genotype
• B. phenotype
• C. temperament
• D. characteristic

Correct answer: C

Rationale: Temperament is the correct answer because it refers to an individual's inborn, relatively permanent trait that distinguishes one person from another. Genotype (choice A) refers to the genetic makeup of an organism, not necessarily a behavioral trait. Phenotype (choice B) is the observable characteristics of an organism resulting from the interaction between its genotype and the environment. Characteristic (choice D) is a broad term that can encompass various traits and features, but it does not specifically denote an inborn and relatively permanent trait that sets individuals apart.

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

• A. Differences in brain function can be easily identified.
• B. Concordance rates tend to be higher.
• C. It is possible that the genetics of twins who have been separated have changed in ways to explain any differences found.
• D. It is possible that high concordance rates between identical twins reared together are due to their being treated more similarly than nonidentical twins.

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.
