Human Growth and Development Final Exam Answers

1. How were baby boomers generally perceived by popular culture and media?

Correct answer: D

Rationale: The statement that baby boomers were labeled a narcissistic, indulged, 'me' generation aligns with the common perception of this generation in popular culture and media. Baby boomers, who were born between 1946 and 1964, have often been characterized in this way due to their reputation for self-centeredness and individualism. Choices A, B, and C are incorrect because they do not accurately reflect the typical perception of baby boomers in popular culture and media.

2. Which factor disrupts the brain's regulation of hunger and metabolism?

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.

3. Today, research that combines an experimental strategy with __________ approach is becoming increasingly common.

Correct answer: C

Rationale: The blank in the statement refers to an approach that can be used in combination with an experimental strategy. Longitudinal and cross-sectional approaches are two common research methods in developmental psychology. Longitudinal studies involve following the same group of individuals over an extended period, while cross-sectional studies compare different groups of individuals of different ages at the same time. By combining an experimental strategy with either a longitudinal or a cross-sectional approach, researchers can gain a deeper understanding of developmental processes and changes over time. Choices A, B, and D are incorrect because correlational and sequential are not the most relevant approaches when studying developmental changes over time in research.

4. What did Ivan Pavlov discover?

Correct answer: B

Rationale: Ivan Pavlov discovered classical conditioning. This is a form of learning in which a neutral stimulus becomes associated with a meaningful stimulus and acquires the capacity to elicit a similar response. Pavlov's famous experiment with dogs, where he conditioned them to salivate at the sound of a bell, demonstrated this principle. Choices A, C, and D are incorrect because Pavlov's work primarily focused on classical conditioning, not observational learning, ego contributions to development, or the clinical method.

5. The more a mental ability depends on __________ intelligence, the earlier it starts to decline.

Correct answer: A

Rationale: The correct answer is A: fluid. Fluid intelligence, which involves problem-solving and reasoning, tends to decline earlier than crystallized intelligence. Crystallized intelligence, on the other hand, involves knowledge and skills acquired over time and is more stable with age. Emotional intelligence and cultural intelligence are not directly related to the decline of mental abilities mentioned in the question, making them incorrect choices.
