Human Growth and Development Final Exam Answers

1. Three-month-old Jefferson will probably listen longer to __________ than to __________.

Correct answer: C

Rationale: Three-month-old Jefferson will likely listen longer to human speech compared to nonspeech sounds because infants have a natural preference for speech sounds. This preference is believed to be attributed to their biological readiness to learn language and communicate with others. Choice A is incorrect because voices are a form of human speech, which is preferred over pure tones. Choice B is incorrect as noises do not necessarily engage infants' attention as effectively as human speech. Choice D is incorrect because Jefferson is more likely to listen longer to his native language rather than a foreign language at this early age.

2. People born during the baby boom between 1946 and 1964 tend to be alike in ways that set them apart from people born at other times due to __________ influences.

Correct answer: B

Rationale: People born during the baby boom between 1946 and 1964 tend to be alike in ways that set them apart from people born at other times due to history-graded influences. These influences refer to the events and conditions that are common to a particular historical era and can significantly shape the development and experiences of individuals who live through them. The post-World War II era, economic prosperity, and social changes during the baby boom period are examples of historical events that have had a lasting impact on this generation.

3. Dr. George predicted that positive reinforcement would increase prosocial behavior in preschoolers. Dr. George's prediction is an example of a __________.

Correct answer: C

Rationale: Dr. George's prediction that positive reinforcement would increase prosocial behavior in preschoolers is an example of a hypothesis. A hypothesis is a specific, testable prediction about the relationship between variables based on existing knowledge or theories. In this case, Dr. George is making a prediction about the effect of positive reinforcement on prosocial behavior, which can be tested through research. Choice A, 'theory,' is incorrect because a theory is a broader explanation that integrates a range of findings and observations. Choice B, 'research question,' is incorrect as it refers to an inquiry that asks about the relationship between variables but lacks the specificity and testability of a hypothesis. Choice D, 'research design,' is incorrect as it pertains to the overall strategy or plan for conducting a research study, not the specific prediction Dr. George made.

4. School-age children master concrete operational tasks ________.

Correct answer: B

Rationale: Correct answer: School-age children master concrete operational tasks gradually, in a continuum of acquisition. Piaget's theory suggests that children develop cognitive abilities in stages, with concrete operational tasks being acquired gradually as part of this process. Choices A, C, and D are incorrect because concrete operational tasks are not typically mastered all at once, much later than Piaget believed, or necessarily after mastering abstract thinking.

5. According to the lifespan perspective, _______ is supreme in its impact on the life course.

Correct answer: D

Rationale: According to the lifespan perspective, no single period is considered supreme in its impact on the life course. Each stage of life, from prenatal period through adulthood, plays a significant role in shaping an individual's development. Therefore, the correct answer is 'D: no age period.' Choices A, B, and C are incorrect because the lifespan perspective emphasizes that all stages are important and contribute uniquely to an individual's life course.
