According to Erikson, when parents are over- or undercontrolling, the outcome is a child who __________.

Correct Answer: A

Rationale: According to Erikson, when parents are over- or undercontrolling, the outcome is a child who feels forced and shamed. This is because overly controlling parents can make the child feel inadequate, leading to a sense of shame and doubt. Choice B, 'acts competently on his own,' is incorrect because overcontrolling parents hinder the child's ability to act independently. Choice C, 'asserts his independence,' is incorrect because overcontrolling parents can actually suppress the child's independence. Choice D, 'feels self-confident,' is incorrect because overcontrolling parenting can undermine the child's confidence and lead to feelings of inadequacy.

Correct Answer: C

Rationale: In females, the twenty-third pair of chromosomes is indeed labeled as XX. This pair of chromosomes determines the biological sex of females. Choice A, 'an autosome,' is incorrect as autosomes refer to the non-sex chromosomes. Choice B, 'dizygotic,' is incorrect as it relates to twins. Choice D, 'XY,' is incorrect as it represents the chromosome pair found in males.

Correct Answer: D

Rationale: The correct answer is 'social referencing.' Social referencing is a behavior where infants seek emotional information from a trusted person, usually a caregiver, to determine how to respond in uncertain situations. This process helps infants regulate their emotions and behaviors based on the cues they receive from the trusted individual. Choices A, B, and C are incorrect because self-control, give-and-take, and emotional self-regulation do not specifically involve seeking emotional information from others in uncertain situations, as social referencing does.

Correct Answer: A

Rationale: Correct answer: Developmental science is interdisciplinary because it integrates knowledge from multiple fields like psychology, biology, and sociology. The term 'empirical' refers to information gained from observation or experimentation, which is not the focus of this question. 'Applied' and 'theoretical' do not capture the essence of developmental science requiring inputs from various disciplines.

Correct Answer: D

Rationale: Breastfeeding for even a short period offers infants protection against respiratory and intestinal infections. Choice A is incorrect because breastfeeding is not a rare practice among American women. Choice B is incorrect as there is no direct link between breastfeeding for a few weeks and later obesity. Choice C is incorrect as breastfeeding does not cause constipation in infants; in fact, it can help prevent constipation.
