Correct Answer: C

Rationale: The correct answer is C: 'high in warmth and moderately high in control.' The authoritative parenting style, associated with the most positive developmental outcomes, is characterized by high levels of warmth and support coupled with moderately high levels of control. This balance allows children to develop independence while feeling secure and valued. Choices A, B, and D are incorrect because the authoritative style is not characterized by low warmth or low control, but rather high warmth and moderate control.

Correct Answer: C

Rationale: The correct answer is C: 'Interaction between genetics and environment.' The genetic study of identical twins reared apart helps in understanding how both genetics and environment play a role in shaping an individual's traits and behaviors. This type of study allows researchers to tease apart the effects of genetic inheritance from those of environmental influences. Choices A, B, and D are incorrect because the study of identical twins reared apart specifically focuses on the interplay between genetics and environment, rather than solely on differences in brain function, genetic influence on behavior, or the role of environmental factors alone.

Correct Answer: C

Rationale: Newer psychodynamic perspectives do not view the libido as a primary determinant of behavior. While Freud's theories focused heavily on the libido as a driving force, newer perspectives have evolved to consider a broader range of factors influencing behavior. Choice A is incorrect as newer perspectives still build upon some elements of Freud's theories. Choice B is incorrect as newer perspectives may not solely emphasize the role of the id. Choice D is incorrect as while intrapsychic conflicts are considered important, they are not always viewed as the sole primary determinant of behavior in newer psychodynamic perspectives.

Correct Answer: D

Rationale: Children from lower-SES families are less likely to show ill effects of SES status if they possess a high IQ and develop healthy attachments. Choice A is incorrect because children from lower-SES families typically face more challenges and are not inherently more resilient. Choice B is incorrect as an increase in SES may not erase the effects of early socioeconomic disadvantages. Choice C is incorrect as SES status can impact children from lower-SES families regardless of the reason for economic hardships.

Correct Answer: B

Rationale: A psychologist who studies the relationship between sociocultural factors and mental disorders would focus on factors like poverty and racial discrimination. These factors have a significant impact on mental health outcomes within different populations. Choices A, C, and D are less directly related to sociocultural factors like poverty and racial discrimination and their influence on mental disorders, making them incorrect.
