Human Growth and Development Exam Questions
1. Longitudinal research can identify common patterns as well as individual differences in development because the investigator __________.
- A. studies groups of participants differing in age at the same point in time
- B. randomly assigns participants to treatment conditions
- C. tracks the performance of each person over time
- D. conducts quasi-experiments, comparing conditions that already exist
Correct answer: C
Rationale: Longitudinal research involves tracking the performance of each person over time. By doing so, researchers can observe common patterns in development among a group of individuals and also identify individual differences in how each person progresses over time. This methodology allows researchers to gather data on the same individuals repeatedly, offering insights into how development unfolds over the lifespan. Choices A, B, and D are incorrect because longitudinal research focuses on observing individuals over time rather than studying groups at a single point, randomly assigning participants to treatments, or conducting quasi-experiments.
2. The most rapid prenatal changes take place in the period of the __________.
- A. zygote
- B. blastocyst
- C. embryo
- D. fetus
Correct answer: C
Rationale: The correct answer is C: embryo. The most rapid prenatal changes occur during the embryo stage, which spans from approximately 2 to 8 weeks after conception. This period is crucial as major organs and systems of the body develop rapidly, laying the foundation for future growth and development. The zygote stage is the initial single-celled entity formed by the union of sperm and egg, while the blastocyst stage involves the cluster of cells resulting from the zygote dividing and growing. The fetus stage follows the embryo stage and focuses on refining and growing existing structures rather than rapid development. Therefore, the embryo stage is where the most significant and rapid changes take place in prenatal development.
3. Which statement about a blastocyst is true?
- A. It consists of a single cell.
- B. It is a structure that feeds the developing organism.
- C. Between the seventh and ninth days, it burrows deep into the uterine lining.
- D. It is a membrane that helps to keep the temperature of the prenatal world constant.
Correct answer: C
Rationale: The statement that is true about a blastocyst is that between the seventh and ninth days, it burrows deep into the uterine lining. This process, known as implantation, is essential for the blastocyst to establish a connection with the mother's body and receive nutrients for further development. It is a critical stage in prenatal development and sets the foundation for pregnancy. Choices A, B, and D are incorrect. A blastocyst is not a single cell but rather a structure composed of many cells. It is not a structure that feeds the developing organism; instead, it implants in the uterine lining to receive nutrients. It is not a membrane that regulates temperature but plays a crucial role in the initial stages of pregnancy by implanting in the uterus.
4. 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.
5. At Kohlberg's Stage __________, individuals can imagine alternatives to their own social order, and they emphasize fair procedures for interpreting and changing the law.
- A. 3, the 'good boy/good girl' orientation
- B. 4, the social-order-maintaining orientation
- C. 5, the social contract orientation
- D. 6, the universal ethical principle orientation
Correct answer: C
Rationale: The correct answer is C: '5, the social contract orientation.' At Kohlberg's Stage 5, individuals begin to question their own social order and focus on principles of justice and fairness. This stage emphasizes the importance of social contracts and agreements based on mutual benefit. Choice A is incorrect as the 'good boy/good girl' orientation is characteristic of Stage 3. Choice B, the social-order-maintaining orientation, does not align with the description provided in the question. Choice D, the universal ethical principle orientation, is associated with Stage 6, where individuals act based on self-chosen ethical principles.
