Human Growth and Development Final Exam Quizlet

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.

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: D

Rationale: The correct answer is D. Development is best understood as a series of complex exchanges between nature (genetic factors) and nurture (environmental influences). This perspective emphasizes the interaction and interplay between genetic predispositions and environmental experiences in shaping an individual's development. Choices A and B are too extreme as they suggest that development is solely determined by genetics or solely influenced by the environment, which is not the case. Choice C is incorrect as development is not viewed as an unsolvable puzzle but rather as a dynamic process influenced by multiple factors.

Correct Answer: C

Rationale: Free radicals may contribute to oxidative stress, increasing the risk of conditions associated with a high-fat diet. When consuming a high-fat diet, the body may produce more free radicals, leading to oxidative damage. Sex hormones, over-the-counter medications, and low body weight do not directly heighten the effects of a high-fat diet like free radicals do.

Correct Answer: C

Rationale: The correct answer is C: concrete operational. During the concrete operational stage, children start to engage in logical thinking about concrete events. This stage typically occurs between the ages of 7 to 11 years. Choices A, B, and D are incorrect. The sensorimotor stage (choice A) is the first stage in Piaget's theory, occurring from birth to about 2 years old. The preoperational stage (choice B) follows the sensorimotor stage and occurs roughly from ages 2 to 7 years. The formal operational stage (choice D) is the final stage in Piaget's theory, where abstract thinking and hypothetical reasoning develop, usually beginning around age 11.
