Heaven was born several weeks before her due date. Although she was small, her birth weight was appropriate, based on time spent in the uterus. Heaven is a __________ infant.

Correct Answer: D

Rationale: Heaven is a preterm infant because she was born early, but her weight is appropriate for the time she spent in the womb. Choice A, 'small-for-date,' is incorrect as it does not specifically indicate that the infant was born before the due date. Choice B, 'small-for-weight,' is incorrect because the infant's weight is appropriate for the gestational age. Choice C, 'mature,' is incorrect as it does not reflect the early birth of the infant.

Correct Answer: C

Rationale: Reduced sleep is the correct answer as it affects hormones that regulate hunger and metabolism, leading to increased appetite and weight gain. Self-regulation is not directly related to the brain's regulation of hunger and metabolism. Frequent eating out may impact food choices and portion sizes but is not specifically linked to disrupting the brain's regulation. Using screen media can affect sleep patterns but is not as directly related to the brain's regulation of hunger and metabolism as reduced sleep.

Correct Answer: D

Rationale: The formal operational stage in Piaget's theory is characterized by abstract reasoning, hypothetical thinking, and logical reasoning. This stage represents the most complex period of cognitive development according to Piaget. Choices A, B, and C refer to earlier stages in Piaget's theory and do not involve the level of abstract thinking and logical reasoning seen in the formal operational stage.

Correct Answer: A

Rationale: Brain growth is especially dramatic during the first year of life when the brain more than doubles in size. This period is characterized by rapid neural development and growth. The brain doesn't double in size during the second year, making choice B incorrect. Middle childhood and adolescence do not represent periods where the brain more than doubles in size, making choices C and D incorrect, respectively.

Correct Answer: A

Rationale: The correct answer is A: 'any environmental agent that causes damage during the prenatal period.' A teratogen is any substance or factor that can cause harm to the developing fetus during pregnancy. Choice B is incorrect because it describes a critical period, not a teratogen. Choice C is incorrect as it refers to a specific period of development, not a teratogen. Choice D is incorrect because it describes a synthetic hormone, not a teratogen.

Correct Answer: B

Rationale: A warm, sensitive parent-child relationship is crucial in fostering a positive and coherent early self-concept in children. This type of relationship provides support, security, and emotional guidance, helping children develop a strong sense of self-worth and self-identity. Permissive parenting (Choice A) may lead to confusion and inconsistency in discipline, impacting the child's self-concept negatively. Authoritarian parenting (Choice C), characterized by strict rules and a lack of warmth, can result in a child feeling insecure and having a negative self-concept. Strong identification with an other-sex parent (Choice D) may influence gender identity development but may not directly impact the early self-concept in the same way a warm and sensitive parent-child relationship does.

Correct Answer: C

Rationale: Erikson's theory of psychosocial development highlights generativity as the central focus of middle adulthood. Generativity involves being productive, caring for others, and contributing to society. This stage is characterized by a desire to leave a lasting impact on future generations. Choices A, B, and D are incorrect. Initiative is associated with the preschool years, autonomy with early childhood, and industry with middle childhood according to Erikson's stages of development.

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: The correct answer is C: 'competition.' Parents often give boys toys that promote competition and physical activity, aligning with traditional gender roles. This emphasis on competition can help boys develop skills such as leadership, strategy, and resilience. Choice A, 'cooperation,' is incorrect because while cooperation is valuable, it is not typically emphasized through toys given to boys. Choice B, 'nurturance,' is also incorrect as nurturing qualities are not commonly associated with toys given to boys. Choice D, 'physical attractiveness,' is unrelated to the toys parents usually give their sons.
