Human Growth and Development Final Exam Answers
1. What is one limitation of the ethnographic method?
- A. Investigators' cultural values sometimes lead them to misinterpret what they see.
- B. It provides little information on how children and adults actually behave.
- C. It relies on unobtrusive techniques, such as surveillance cameras and one-way mirrors.
- D. It provides little information about the reasoning behind participants' responses.
Correct answer: A
Rationale: The limitation of the ethnographic method is that investigators' cultural values sometimes lead them to misinterpret what they see. This can introduce bias into the observations and potentially impact the accuracy of the findings. It is important for researchers to be aware of their own biases and strive to minimize their influence when conducting ethnographic studies. Choice B is incorrect because ethnographic methods actually aim to provide rich information on how individuals behave within their cultural contexts. Choice C is incorrect as ethnographic methods typically involve direct observation and participation rather than unobtrusive techniques like surveillance cameras. Choice D is incorrect because one of the strengths of ethnographic research is its ability to uncover the reasoning behind participants' responses by immersing the researcher in the cultural setting.
2. Dr. Wu observes children’s responses to bullying by watching them play in a park. This is an example of a(n) __________.
- A. ethnographic study
- B. naturalistic observation
- C. structured observation
- D. clinical interview Answer: B Page Ref: 28 Skill Level: Apply Topic: Studying Development Difficulty Level: Moderate
Correct answer: B
Rationale: Dr. Wu's observation of children's responses to bullying by watching them play in a park is an example of naturalistic observation. Naturalistic observation involves observing behavior in a natural setting without any manipulation or intervention. Dr. Wu is simply observing the children's behavior in a real-world setting to gain insights into how they respond to bullying, making it a naturalistic observation.
3. The immune response is the combined work of specialized cells that neutralize or destroy __________ in the body.
- A. T cells
- B. B cells
- C. telomeres
- D. antigens
Correct answer: D
Rationale: The correct answer is D, antigens. Antigens are substances recognized by the immune system as foreign, triggering an immune response to neutralize or destroy them. In this context, T cells and B cells are specialized cells of the immune system that respond to antigens, but they are not the substances being neutralized or destroyed. Telomeres, on the other hand, are protective structures at the end of chromosomes and are not targeted for neutralization or destruction by the immune system.
4. Developmental science is __________ because it has grown through the combined efforts of people from many fields of study.
- A. interdisciplinary
- B. empirical
- C. applied
- D. theoretical
Correct answer: A
Rationale: Correct answer: Developmental science is interdisciplinary because it integrates knowledge from multiple fields like psychology, biology, and sociology. The term 'empirical' refers to information gained from observation or experimentation, which is not the focus of this question. 'Applied' and 'theoretical' do not capture the essence of developmental science requiring inputs from various disciplines.
5. Which of the following best describes a sequential design?
- A. Does not address diversity in developmental outcomes.
- B. Permits researchers to check if cohort effects are operating.
- C. Is less efficient than a longitudinal design.
- D. Makes cross-sectional, but not longitudinal, comparisons.
Correct answer: B
Rationale: A sequential design permits researchers to check if cohort effects are operating. This design involves combining cross-sectional and longitudinal research, allowing for the comparison of different cohorts at different ages. By using this approach, researchers can determine if developmental changes observed are due to age or generation-specific factors. Therefore, a sequential design is valuable in addressing the potential influence of cohort effects on developmental outcomes. Choices A, C, and D are incorrect because a sequential design does not neglect diversity in developmental outcomes, is not necessarily less efficient than a longitudinal design, and can make both cross-sectional and longitudinal comparisons.
