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

• A. Sammy, a preschool child
• B. Jake, a full-term newborn
• C. Sarah, a teenager
• D. Cheryl, a preterm newborn Answer: D Page Ref: 104 Copyright © 2018 Laura E. Berk. All Rights Reserved. 32 Test Bank for Berk, Development Through the Lifespan, 7e Skill Level: Apply Topic: The Newborn Baby’s Capacities Difficulty Level: Moderate

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.

2. Which sense is the least-developed in newborn babies?

• A. Taste
• B. Sound
• C. Vision
• D. Touch

Correct answer: C

Rationale: Vision is the least-developed sense in newborn babies. While newborns can see, their vision is not as developed as their other senses at birth. Taste, sound, and touch are more developed senses in newborns compared to vision. Over time, through visual stimulation and experiences, a baby's vision gradually improves and develops.

3. 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.

4. A combined Apgar score of __________ indicates that the infant is in good physical condition.

• A. less than 3
• B. 3 or 4
• C. 5 or 6
• D. 7 or better

Correct answer: D

Rationale: A combined Apgar score of 7 or better indicates that the infant is in good physical condition. The Apgar score is a quick assessment of a newborn's overall health shortly after birth. It evaluates the baby's heart rate, respiratory effort, muscle tone, reflexes, and color. A score of 7 or higher indicates that the baby is adjusting well to life outside the womb. Choices A, B, and C are incorrect as they represent scores that indicate the infant may need medical attention or assistance as they are below the threshold of 7 which signifies good physical condition.

5. Researchers randomly assigned adolescents to either a single-grade classroom or a mixed-age classroom. This is an example of a __________.

• A. naturalistic observation
• B. case study
• C. natural experiment
• D. field experiment

Correct answer: D

Rationale: In this scenario, the researchers randomly assigned adolescents to either a single-grade classroom or a mixed-age classroom, which is an example of a field experiment. A field experiment involves manipulating independent variables in a natural setting to observe the effects on participants. This design allows for more control over variables compared to naturalistic observation, case studies, or natural experiments. Naturalistic observation involves observing subjects in their natural environment without manipulating any variables. A case study focuses on in-depth analysis of a single individual or a small group. A natural experiment involves observing naturally occurring events without intervention or manipulation by the researcher.
