Human Growth and Development Exam Questions
1. What reflex protects an infant from strong stimulation?
- A. Moro
- B. eye-blink
- C. sucking
- D. palmar grasp
Correct answer: B
Rationale: The correct answer is B: eye-blink. The eye-blink reflex is the one that protects an infant from strong stimulation by causing them to quickly shut their eyes in response to sudden bright light or a loud noise. This reflex helps to safeguard the infant's sensitive eyes from potential harm. The Moro reflex (choice A) is the startle reflex, the sucking reflex (choice C) helps with feeding, and the palmar grasp reflex (choice D) is when the infant's fingers close around an object placed in their hand; none of these reflexes specifically protect the infant from strong stimulation.
2. 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.
3. In healthy, physically fit women, regular moderate to vigorous exercise during pregnancy is related to __________.
- A. lower birth weight and higher risk of premature birth
- B. suppressed development of the immune system
- C. serious damage to the central nervous system
- D. improved fetal cardiovascular functioning
Correct answer: D
Rationale: In healthy, physically fit women, regular moderate to vigorous exercise during pregnancy is related to improved fetal cardiovascular functioning. Regular exercise has been shown to benefit both the mother and baby by promoting better cardiovascular health and overall well-being during pregnancy. Choices A, B, and C are incorrect as exercise during pregnancy, when done appropriately, does not lead to lower birth weight, higher risk of premature birth, suppressed immune system development, or serious damage to the central nervous system. Instead, it is known to have positive effects on fetal development and maternal health.
4. Adolescent children of mothers who were home-visited as part of the Nurse-Family Partnership __________ than comparison-group agemates.
- A. scored lower in impulsivity and overactivity
- B. had lower academic achievement scores
- C. showed more aggressive behavior
- D. reported less alcohol and drug use
Correct answer: D
Rationale: Adolescent children of mothers who were home-visited as part of the Nurse-Family Partnership reported less alcohol and drug use compared to their comparison-group agemates. This indicates that the program may have a positive impact in reducing risky behaviors among adolescents whose mothers received home visits. Choices A, B, and C are incorrect because the extract specifically mentions that the children reported less alcohol and drug use, and there is no mention of impulsivity, overactivity, academic achievement scores, or aggressive behavior in this context.
5. The harm done by teratogens __________.
- A. is straightforward and predictable
- B. is usually apparent at birth
- C. rarely goes beyond physical damage
- D. depends on age at the time of exposure
Correct answer: D
Rationale: The harm done by teratogens depends on the age at the time of exposure. This means that the effects may vary depending on the developmental stage of the fetus when exposed to the teratogen. Teratogens can have different impacts at different stages of pregnancy, leading to a range of potential outcomes in terms of physical and/or cognitive development. Choices A, B, and C are incorrect because the harm caused by teratogens is not straightforward, may not be apparent at birth, and can go beyond physical damage, affecting cognitive development as well.
