Psychology 2301 Exam 1

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.

Correct Answer: B

Rationale: Neural plasticity refers to the brain's flexibility to change existing neural circuits or create new ones. Choice A is incorrect as it describes neurotransmitter breakdown, not neural plasticity. Choice C is incorrect because neural plasticity does not necessarily indicate brain damage leading to mental disorders. Choice D is incorrect because neural plasticity is not specifically related to temperament or personality development in children.

Correct Answer: A

Rationale: Overly aggressive behavior is often a major factor in a child's rejection by peers. Children who display overly aggressive behavior may intimidate or harm their peers, leading to social rejection. Being too intelligent or having a different socioeconomic background are not typically primary reasons for peer rejection. While empathy is important for healthy social interactions, a lack of empathy, on its own, is less likely to be a primary factor in peer rejection compared to overly aggressive behavior.

Correct Answer: B

Rationale: The correct answer is B because most behaviors are influenced by a complex interaction of many genes and the environment. Choice A is incorrect because it states that it is easy to differentiate between the effects of the environment and genes, which is not the case. Choice C is incorrect because although twin studies are commonly used in genetic research, this alone does not hinder the full understanding of genetic influences on behavior. Choice D is incorrect because even though we have some understanding of how genes impact brain chemistry, this does not mean that we fully understand the genetic influences on behavior.

Correct Answer: C

Rationale: The authoritative parenting style is associated with the most positive developmental outcomes. Authoritative parents are responsive to their children's needs while also setting clear expectations and boundaries. This balance fosters a supportive environment that allows children to develop autonomy, self-confidence, and social skills. Authoritarian parenting (choice A) is characterized by strict rules and harsh discipline, leading to less favorable outcomes. Permissive/indulgent parenting (choice B) involves being lenient and overly responsive, which can result in children lacking self-discipline. Neglectful/uninvolved parenting (choice D) is marked by a lack of responsiveness and involvement, resulting in negative developmental outcomes.
