Human Growth and Development Exam 1
1. In a longitudinal design, participants are studied repeatedly at different ages, and changes are noted as they get older.
- A. cross-sectional
- B. experimental
- C. longitudinal
- D. correlational
Correct answer: C
Rationale: The correct answer is C: longitudinal. In a longitudinal design, participants are followed and studied over an extended period, allowing researchers to observe changes and continuity in development as individuals age. This design is crucial for understanding how individuals grow and change over time. Cross-sectional studies (Choice A) involve comparing different groups at the same time point, while experimental studies (Choice B) involve manipulating variables to observe their effects. Correlational studies (Choice D) examine relationships between variables but do not involve studying participants over time.
2. According to the lifespan perspective, _______ is supreme in its impact on the life course.
- A. the prenatal period
- B. early childhood
- C. adolescence
- D. no age period
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.
3. To study the impact of biological aging on motor skills, researchers focus on __________.
- A. sedentary adults
- B. competitive athletes
- C. men in their mid- to late thirties
- D. women in their childbearing years
Correct answer: B
Rationale: The correct answer is B: competitive athletes. Competitive athletes are often studied by researchers to investigate the impact of biological aging on motor skills because their performance is closely linked to physical abilities. Sedentary adults (choice A) may not provide a clear understanding of the relationship between biological aging and motor skills as they may not engage in consistent physical activity. Men in their mid- to late thirties (choice C) and women in their childbearing years (choice D) may not represent a group where motor skills are as finely tuned and critical to performance as in competitive athletes.
4. How were baby boomers generally perceived by popular culture and media?
- A. They were more economically underprivileged than their counterparts in the previous generation
- B. They adopted their parents' family- and marriage-centered lifestyles in early adulthood
- C. They embraced growing old far more than their predecessors
- D. They were labeled a narcissistic, indulged, 'me' generation
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.
5. Low-level radiation, resulting from industrial leakage or medical X-rays, __________.
- A. is harmful only when combined with other teratogens
- B. can increase the risk of childhood cancer
- C. rarely causes lasting damage
- D. is safe during the last trimester
Correct answer: B
Rationale: Low-level radiation, whether from industrial leakage or medical X-rays, can increase the risk of childhood cancer by potentially damaging the developing fetus's cells. Even though the risk is relatively low, it is still a significant concern that should be acknowledged and monitored closely, especially during prenatal development. Choice A is incorrect as low-level radiation can still be harmful on its own without the need to be combined with other teratogens. Choice C is incorrect because low-level radiation exposure can indeed cause lasting damage, especially in the context of childhood cancer risk. Choice D is incorrect because low-level radiation exposure, even during the last trimester, can pose risks to the developing fetus and is not considered entirely safe.
