Human Growth and Development Final Exam Answers
1. Which mother is most likely to have had inadequate prenatal care?
- A. Lupe, age 25
- B. Marissa, age 32
- C. Rotunda, age 16
- D. Janette, age 40
Correct answer: C
Rationale: Rotunda, age 16, is the most likely to have had inadequate prenatal care due to her young age and possibly limited access to healthcare resources and support. Adolescents are at higher risk for inadequate prenatal care compared to older mothers due to various factors such as lack of awareness, financial constraints, and inconsistent health behaviors. Young mothers may face challenges in seeking proper prenatal care due to reasons like lack of knowledge, fear of judgment, or limited financial means. Older mothers like Lupe, Marissa, and Janette are less likely to have inadequate prenatal care compared to a younger mother like Rotunda, as they may have more access to resources, experience, and support systems.
2. Like longitudinal research, cross-sectional studies can be threatened by __________.
- A. practice effects
- B. participant dropout
- C. sequential timing
- D. cohort effects
Correct answer: D
Rationale: Cross-sectional studies can be threatened by cohort effects because different age groups may have experienced different historical or social contexts, influencing the results. This disparity can lead to invalid comparisons between age groups, confounding the study's findings. Option A, practice effects, refer to changes in participants' behavior due to repeated testing, not a specific threat to cross-sectional studies. Participant dropout (Option B) is a threat related to attrition in longitudinal studies, not cross-sectional studies. Sequential timing (Option C) does not pose a threat to cross-sectional studies; instead, it refers to the order of tasks in a study design.
3. Which statement provides an example of an age-graded influence?
- A. Paul learned to play the violin at a young age.
- B. Jack enjoys hiking in the mountains.
- C. Sarah prefers reading mystery novels.
- D. Alex excels in mathematics.
Correct answer: A
Rationale: The corrected statement 'Paul learned to play the violin at a young age' provides an example of an age-graded influence. This is because learning to play the violin is a behavior that is typical or expected at a certain age, reflecting how age influences individuals' experiences and development. In contrast, choices B, C, and D do not directly relate to age-graded influences. Jack's enjoyment of hiking, Sarah's preference for reading mystery novels, and Alex's proficiency in mathematics are not inherently tied to age-related developmental influences.
4. What is strongly associated with healthy eating in teenagers?
- A. Vitamin supplementation
- B. Number of hours of sleep
- C. Dieting in adolescence
- D. Frequency of family meals
Correct answer: D
Rationale: The frequency of family meals is strongly associated with healthy eating in teenagers. Research indicates that regular family meals provide structure, promote positive eating behaviors, and offer opportunities for modeling healthy food choices. Vitamin supplementation (Choice A) may be beneficial but is not as strongly linked to healthy eating habits as family meal frequency. The number of hours of sleep (Choice B) is important for overall health but is not as directly associated with healthy eating behaviors in teenagers. Dieting in adolescence (Choice C) can sometimes lead to unhealthy eating patterns and is not necessarily linked to consistently healthy food choices.
5. Under ethical standards, when is deception permitted in research studies?
- A. if the participants are young enough that they would not understand the deception
- B. if investigators satisfy institutional review boards that such practices are necessary
- C. if researchers can observe participants from behind one-way mirrors
- D. if the participants give informed consent and the researchers never reveal the real purpose of the study
Correct answer: B
Rationale: Ethical standards permit deception in research studies if investigators satisfy institutional review boards that such practices are necessary. Institutional review boards are responsible for ensuring that research studies comply with ethical guidelines and protect the welfare of study participants. Deception should only be used when necessary, and the board's approval indicates that safeguards are in place to minimize harm to participants. Choices A, C, and D are incorrect because ethical deception in research studies is not based on the age of participants, observing from behind mirrors, or obtaining informed consent without revealing the study's real purpose.
