Psychology 2301 Exam 1

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.

Correct Answer: B

Rationale: Permissive parenting is associated with positive developmental outcomes because it involves warmth and a lack of strict control. Authoritarian parenting, as mentioned in choice A, is characterized by strict rules and harsh discipline, which may not lead to the best developmental outcomes. Neglectful parenting, as in choice C, involves a lack of responsiveness and support, which can have detrimental effects on a child's development. Choice D is incorrect because different parenting styles can have varying impacts on child development.

Correct Answer: B

Rationale: The correct answer is B because most behaviors are influenced by the interaction of multiple genes and the environment. Choice A is incorrect because it suggests that researching the effects of the environment and genes is easy, which is not the case. Choice C is incorrect as it focuses on a specific method (twin studies) rather than the broader concept of gene-environment interaction. Choice D is incorrect as the statement implies a high level of understanding that contradicts the idea that genetic influences on behavior may never be fully understood.

Correct Answer: A

Rationale: A diathesis is indeed the correct term for a predisposition toward developing a disorder. A diathesis refers to an underlying vulnerability or predisposition to a particular condition. Choice B, 'comorbidity,' refers to the presence of two or more disorders in the same individual. Choice C, 'genotype,' relates to an individual's genetic makeup. Choice D, 'phenotype,' refers to the observable characteristics of an organism resulting from the interaction of its genotype with the environment. Therefore, A is the most appropriate term for describing a predisposition toward developing a disorder.

Correct Answer: C

Rationale: The correct answer is C: 'have cardiovascular reactivity.' Consistent discrimination can lead to increased cardiovascular reactivity, impacting heart health. Choice A ('be happy') is incorrect because discrimination typically causes distress and negative emotions. Choice B ('be more conscious') is not directly related to the impact of discrimination. Choice D ('have greater intelligence and wisdom') is also unrelated to the physiological response of cardiovascular reactivity caused by discrimination.
