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. Albert has brown eyes, even though one of his biological parents has blue eyes. Genes for blue eyes are part of Albert's ___.

• A. Phenotype
• B. Zygote
• C. Genotype
• D. Environment

Correct answer: C

Rationale: Albert's genotype refers to the genetic makeup inherited from his parents, which includes the genes for blue eyes. The phenotype, on the other hand, is the observable trait, in this case, brown eyes. Therefore, the correct answer is C. Choice A (Phenotype) is incorrect as it refers to the observable characteristics, not the genetic information. Choice B (Zygote) is incorrect as it refers to the initial stage of a developing organism. Choice D (Environment) is incorrect as it does not directly determine eye color.

3. 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.

4. Scientific research has demonstrated the __________ parenting style is most likely to lead to healthy psychological development in children.

• A. Authoritarian
• B. Permissive
• C. Authoritative
• D. Neglectful

Correct answer: C

Rationale: Scientific research has demonstrated that the authoritative parenting style is most likely to lead to healthy psychological development in children. Authoritative parents are responsive to their children's emotional needs, set clear boundaries, and encourage independence. This balance fosters a positive environment for children to thrive emotionally and psychologically. Authoritarian parenting (choice A) focuses on strict rules without much warmth, which can lead to obedience but may hinder emotional development. Permissive parenting (choice B) lacks structure and rules, potentially resulting in children feeling insecure. Neglectful parenting (choice D) is characterized by a lack of responsiveness and involvement, leading to various negative outcomes for the child's development.

5. Deferred imitation of a caregiver's behavior shows that toddlers have the capacity to form?

• A. Short-term memory
• B. Working memory
• C. Core memories
• D. Long-term memory

Correct answer: D

Rationale: Deferred imitation refers to the ability of toddlers to observe and replicate behaviors after a period of time, indicating the formation of long-term memories. This process involves storing information for an extended period and recalling it at a later time. This capacity is not attributed to short-term memory (choice A), which is more temporary in nature and has limited storage capacity. Working memory (choice B) involves the temporary storage and manipulation of information for cognitive tasks, not necessarily the long-term retention of behaviors. Core memories (choice C) are typically associated with emotional or significant events rather than the replication of observed behaviors. Therefore, the correct answer is choice D, as deferred imitation demonstrates toddlers' capability to form long-term memories by replicating behaviors observed earlier.
