Human Growth and Development Final Exam
1. Theorists who contend that powerful negative events in the first few years cannot be fully overcome by later, more positive ones emphasize __________.
- A. plasticity
- B. stability
- C. nurture
- D. discontinuity
Correct answer: B
Rationale: Theorists who emphasize stability argue that powerful negative events early in life cannot be completely overcome by later, more positive experiences. They believe that early experiences have a lasting impact on development and are not easily erased or reversed by subsequent events. This perspective contrasts with the idea of plasticity, which suggests that development can be influenced by experiences at any point in life, and that individuals have the capacity for change and growth throughout the lifespan. 'Nurture' does not directly address the concept of overcoming negative events, while 'discontinuity' refers to developmental stages being separate and distinct, not the idea that negative events early in life persist despite later positive experiences.
2. __________, a strong type of painkiller used in labor and delivery, blocks sensation.
- A. Anesthetics
- B. Analgesics
- C. Anti-inflammatories
- D. Folic acids
Correct answer: A
Rationale: Anesthetics, such as epidurals, are a strong type of painkiller used in labor and delivery that block sensation. They work by numbing the nerves in the lower part of the spine, providing pain relief during childbirth. Choice B, Analgesics, are pain relievers that reduce pain without causing loss of consciousness, but they are not as strong as anesthetics for labor pain. Choice C, Anti-inflammatories, are medications that reduce inflammation and do not directly block sensation like anesthetics. Choice D, Folic acids, are a type of B vitamin crucial for cell growth and metabolism, not used as painkillers in labor and delivery.
3. What is one strength of the cross-sectional design?
- A. It provides evidence about individual trends.
- B. It cannot be threatened by cohort effects.
- C. It is not plagued with dropout or practice effects.
- D. It permits longitudinal comparisons. Answer: C Page Ref: 34 Skill Level: Understand Topic: Studying Development Difficulty Level: Moderate
Correct answer: C
Rationale: One strength of the cross-sectional design is that it is not plagued with dropout or practice effects. This is because cross-sectional studies assess different individuals at the same point in time, eliminating the risk of participants dropping out or improving due to repeated measures.
4. 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.
5. During prenatal development, the ectoderm becomes the __________.
- A. muscles and skeleton
- B. nervous system and skin
- C. circulatory system and other internal organs
- D. digestive system, lungs, urinary tract, and glands
Correct answer: B
Rationale: The correct answer is B: nervous system and skin. The nervous system, which includes the brain, spinal cord, and nerves, as well as the skin, develop from the ectoderm layer of cells during prenatal development. Choice A is incorrect because muscles and skeleton develop from mesoderm. Choice C is incorrect because the circulatory system and other internal organs develop from mesoderm and endoderm. Choice D is incorrect because the digestive system, lungs, urinary tract, and glands develop from endoderm.
