Human Growth and Development Final Exam Answers
1. __________ emerges early prenatally and is well-developed at birth.
- A. Visual acuity
- B. Color vision
- C. Depth perception
- D. Sensitivity to touch
Correct answer: D
Rationale: Sensitivity to touch emerges early prenatally and is well-developed at birth. Newborn babies have a well-developed sense of touch, which is crucial for bonding with their caregivers and exploring their environment. This sensitivity to touch helps babies respond to comforting sensations such as gentle strokes and cuddles. Visual acuity, color vision, and depth perception are sensory capabilities that develop and mature after birth, not prenatally. While important for interacting with the environment, they are not as well-developed at birth as sensitivity to touch.
2. Development is best understood as __________.
- A. genetically determined
- B. environmentally influenced
- C. an unsolvable puzzle
- D. a series of complex exchanges between nature and nurture
Correct answer: D
Rationale: The correct answer is D. Development is best understood as a series of complex exchanges between nature (genetic factors) and nurture (environmental influences). This perspective emphasizes the interaction and interplay between genetic predispositions and environmental experiences in shaping an individual's development. Choices A and B are too extreme as they suggest that development is solely determined by genetics or solely influenced by the environment, which is not the case. Choice C is incorrect as development is not viewed as an unsolvable puzzle but rather as a dynamic process influenced by multiple factors.
3. In the __________ period, teratogens rarely have any impact.
- A. germinal
- B. embryonic
- C. fetal
- D. prenatal
Correct answer: A
Rationale: In the germinal period of prenatal development, which lasts for about the first two weeks after fertilization, the developing organism is a zygote that has not yet implanted in the uterus. During this period, teratogens rarely have any impact because essential implantation and early cellular division processes are occurring. Teratogens are more likely to have significant effects during the later embryonic and fetal periods of development. Therefore, the correct answer is A. Choice B, embryonic period, is incorrect because teratogens have a higher likelihood of impacting development during this period. Choice C, fetal period, is also incorrect as teratogens can impact development during this stage as well. Choice D, prenatal, is a broad term encompassing the entire period of development from conception to birth and is not a specific developmental stage where teratogens have a minimal impact.
4. 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.
5. Cindy tells her daughter, “I know you can do a good job on that homework†because she believes that if she encourages persistence, her daughter will start to view herself as hardworking and high-achieving. Cindy is applying the __________ approach.
- A. behavior modification
- B. psychosocial
- C. cognitive-developmental
- D. social-cognitive Answer: D Page Ref: 17 Skill Level: Apply Topic: Mid-Twentieth-Century Theories Difficulty Level: Difficult
Correct answer: D
Rationale: Cindy is applying the social-cognitive approach by encouraging her daughter to believe in her own abilities and persist in her efforts. This approach emphasizes the importance of social influences and cognitive processes in shaping behavior. By providing positive reinforcement and fostering a belief in her daughter's capabilities, Cindy is helping to shape her daughter's self-perception and motivation to achieve success.
