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. Baby Azeez's limb movements are gentle. He stirs occasionally, and facial grimacing occurs. Although his eyelids are closed, occasional rapid eye movements can be seen beneath them. Azeez is most likely in which state?
- A. regular sleep
- B. drowsiness
- C. irregular sleep
- D. quiet alertness
Correct answer: C
Rationale: The description of Baby Azeez's behavior matches the characteristics of irregular sleep in a newborn. During irregular sleep, limb movements are gentle, occasional facial grimacing occurs, and rapid eye movements can be seen beneath closed eyelids. This state is also known as active sleep and is associated with dreaming in newborns. Choice A, regular sleep, is incorrect as the described behaviors are not typical of this state. Choice B, drowsiness, does not match the active movements and facial grimacing observed in Azeez. Choice D, quiet alertness, is also incorrect as it does not align with the described behaviors of limb movements, facial grimacing, and rapid eye movements.
3. The effects of stress on the developing organism can be greatly reduced if the expectant mother __________.
- A. has access to social support during stressful periods
- B. takes a low dose of anti-anxiety medication
- C. takes a folic acid supplement early in pregnancy
- D. is placed on bed rest during the last trimester
Correct answer: A
Rationale: Having access to social support during stressful periods can greatly reduce the effects of stress on the developing organism. Social support can provide emotional comfort, practical assistance, and a sense of belonging, which can help the expectant mother cope with stress more effectively. This support system can also help mitigate the negative impact of stress on the developing baby during pregnancy. Choices B, C, and D are incorrect because while folic acid is important for prenatal health, it does not directly address the effects of stress. Taking anti-anxiety medication should be done under medical supervision and as a last resort due to potential risks to the developing baby. Bed rest during the last trimester is not a solution to reduce the effects of stress and may not address the underlying causes of stress.
4. Vygotsky saw __________ as the foundation for all higher cognitive processes.
- A. egocentrism
- B. language
- C. sensorimotor activity
- D. self-reflection
Correct answer: B
Rationale: Corrected Rationale: Vygotsky believed that language plays a crucial role in the development of higher cognitive functions. Language enables individuals to communicate, think abstractly, and engage in complex problem-solving, forming the foundation for higher cognitive processes. Egocentrism (Choice A) refers to a stage in Piaget's theory of cognitive development, not Vygotsky's. Sensorimotor activity (Choice C) is part of Piaget's stages of cognitive development, focusing on how infants understand the world through sensory experiences and physical actions. Self-reflection (Choice D) involves introspection and examination of one's thoughts and feelings, which is not the central concept in Vygotsky's theory.
5. What is a major disadvantage of cross-sectional research?
- A. Age-related changes cannot be examined.
- B. Participants often drop out before the study is over.
- C. Factors affecting individual development cannot be explored.
- D. Practice effects often cause biased findings.
Correct answer: C
Rationale: One major disadvantage of cross-sectional research is that factors affecting individual development cannot be explored thoroughly. Cross-sectional research involves comparing different groups of people at one specific point in time, and does not allow for tracking individual changes over time. This limitation means that the unique influences and trajectories of individual development may be overlooked in cross-sectional studies. Choices A, B, and D are incorrect. Choice A is not a major disadvantage of cross-sectional research as age-related changes can still be compared across different groups in this type of study. Choice B, while a potential issue in any study, is not specific to cross-sectional research. Choice D refers to a different type of bias caused by repeated testing rather than a major disadvantage of cross-sectional research.
