Growth and Development Exam

1. A 20-week-old fetus can __________.

Correct answer: A

Rationale: A 20-week-old fetus is able to be stimulated as well as irritated by sounds because by this stage of prenatal development, the fetus's auditory system is already well-developed. It can respond to external sounds and may even startle or move in reaction to loud noises.

2. What did Ivan Pavlov discover?

Correct answer: B

Rationale: Ivan Pavlov discovered classical conditioning. This is a form of learning in which a neutral stimulus becomes associated with a meaningful stimulus and acquires the capacity to elicit a similar response. Pavlov's famous experiment with dogs, where he conditioned them to salivate at the sound of a bell, demonstrated this principle. Choices A, C, and D are incorrect because Pavlov's work primarily focused on classical conditioning, not observational learning, ego contributions to development, or the clinical method.

3. Although great diversity characterizes the interests and concerns of investigators who study development, they share a single goal: to identify __________.

Correct answer: D

Rationale: The correct answer is D because investigators who study development aim to identify the factors that influence consistencies and transformations in people from conception to death. This goal encompasses various domains such as physical, cognitive, emotional, and social development, highlighting the comprehensive nature of developmental research. Choices A, B, and C are incorrect as they do not align with the overarching goal of developmental researchers, which is to understand the factors influencing individuals throughout their lifespan, rather than focusing solely on genetic factors, environmental factors related to disease, or abnormal development in specific age groups.

4. To overcome some of the limitations of traditional developmental designs, investigators sometimes use __________ designs, in which they conduct several similar cross-sectional or longitudinal studies.

Correct answer: A

Rationale: Sequential designs involve conducting multiple similar cross-sectional or longitudinal studies to overcome limitations of traditional developmental designs. By combining different types of study designs, researchers can gain a more comprehensive understanding of development over time. This approach allows for more robust conclusions and can help address potential confounding variables that may impact the results.

5. Which individual is most likely to experience the greatest percentage of REM sleep?

Correct answer: D

Rationale: Preterm newborns, like Cheryl, experience a higher percentage of REM sleep compared to full-term newborns. This is because REM sleep plays a critical role in brain development, and preterm infants have an increased need for brain development due to their early arrival. Therefore, Cheryl, as a preterm newborn, is most likely to experience the greatest percentage of REM sleep among the individuals listed.
