Human Growth and Development Final Exam Answers
1. What is one challenge associated with longitudinal research?
- A. It does not allow for inferences about cause-and-effect relationships.
- B. Participants may relocate or drop out of the study.
- C. Findings may not be applicable to real-world scenarios.
- D. It does not allow for the examination of individual developmental patterns.
Correct answer: B
Rationale: One challenge associated with longitudinal research is that participants may relocate or drop out of the study over time. This can result in missing data and potential biases in the findings, impacting the study's overall validity and reliability. Furthermore, it can present difficulties for researchers in accurately monitoring and analyzing changes in individuals over an extended period. Options A, C, and D are incorrect because longitudinal research can indeed allow for inferences about cause-and-effect relationships, findings can be generalized to the real world with appropriate design and sampling, and it is suitable for studying individual developmental patterns.
2. Dr. Rizvi studies the relationship between changes in the brain and the developing person's cognitive processing and behavior patterns. She is part of a group of researchers from the fields of psychology, biology, neuroscience, and medicine. This approach to development is known as __________.
- A. behaviorism
- B. cognitive-development theory
- C. the information-processing approach
- D. developmental cognitive neuroscience
Correct answer: D
Rationale: Dr. Rizvi's approach to development, involving studying the relationship between changes in the brain and cognitive processing and behavior patterns, aligns with developmental cognitive neuroscience. This field combines research from various disciplines to understand how brain development influences cognitive processes and behaviors. Choice A, behaviorism, focuses on observable behaviors influenced by external stimuli. Choice B, cognitive-development theory, emphasizes cognitive growth stages. Choice C, the information-processing approach, centers on how individuals perceive, store, and retrieve information.
3. Lanugo ________.
- A. permits food and oxygen to reach the organism
- B. provides the fetus a cushion against jolts caused by the mother's movements
- C. helps regulate the fetus's body temperature
- D. helps the vernix stick to the skin
Correct answer: D
Rationale: Lanugo helps the vernix stick to the skin. Vernix is a waxy substance that covers the fetus's skin during pregnancy. Lanugo is a fine, downy hair that helps to anchor the vernix to the skin, providing protection and nourishment to the developing fetus. Choices A, B, and C are incorrect as they do not accurately describe the role of lanugo in prenatal development.
4. How can families prevent escalating demands that lead to chaos?
- A. Parental multitasking
- B. Eating separate meals
- C. Compression of family routines
- D. High-quality child care that is affordable and reliable
Correct answer: D
Rationale: High-quality child care that is affordable and reliable can help prevent escalating demands on families that lead to chaos. This is achieved by providing a stable and supportive environment for children, enabling parents to balance work and family responsibilities effectively. Access to reliable child care reduces stress and helps in preventing chaos within the family, ultimately leading to improved well-being for both parents and children. Choices A, B, and C are incorrect as they do not directly address the need for external support to manage family demands and prevent chaos. Parental multitasking, eating separate meals, and compressing family routines may not provide the necessary stability and support required to prevent escalating demands on families.
5. During which period does the germinal period occur?
- A. Occurs during the second trimester of pregnancy
- B. Lasts about six weeks
- C. Lasts about two weeks
- D. Is the final period of a 38-week pregnancy
Correct answer: C
Rationale: The germinal period lasts about two weeks and occurs during the first two weeks of pregnancy. This is the time when the fertilized egg implants into the uterus and begins to divide rapidly. It is followed by the embryonic period, which lasts from about week 3 to week 8 of pregnancy. Choice A is incorrect because the germinal period happens in the early stages of pregnancy, not the second trimester. Choice B is incorrect because the germinal period typically lasts about two weeks, not six. Choice D is incorrect because the germinal period is an early stage of pregnancy and not the final period of a 38-week pregnancy.
