Human Growth and Development Exam Questions
1. Liz is 36 weeks pregnant. A rise in her baby's heart rate is probably followed within five seconds by __________.
- A. a burst of motor activity
- B. a period of sleep
- C. a rise in Liz's heart rate
- D. a drop in Liz's body temperature
Correct answer: A
Rationale: A rise in the baby's heart rate during pregnancy is usually followed within five seconds by a burst of motor activity. This indicates that the baby is responding to stimuli and is an important sign of healthy fetal development. A period of sleep, a rise in Liz's heart rate, or a drop in Liz's body temperature are not typically immediate responses to changes in the baby's heart rate. Sleep is less likely to be a direct response to changes in heart rate, Liz's heart rate is independent of the baby's heart rate changes, and a drop in Liz's body temperature is not a common immediate response to fetal heart rate changes.
2. 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.
3. Today, research that combines an experimental strategy with __________ approach is becoming increasingly common.
- A. both a correlational and a sequential
- B. either a correlational or a sequential
- C. either a longitudinal or a cross-sectional
- D. both a correlational and a longitudinal
Correct answer: C
Rationale: The blank in the statement refers to an approach that can be used in combination with an experimental strategy. Longitudinal and cross-sectional approaches are two common research methods in developmental psychology. Longitudinal studies involve following the same group of individuals over an extended period, while cross-sectional studies compare different groups of individuals of different ages at the same time. By combining an experimental strategy with either a longitudinal or a cross-sectional approach, researchers can gain a deeper understanding of developmental processes and changes over time. Choices A, B, and D are incorrect because correlational and sequential are not the most relevant approaches when studying developmental changes over time in research.
4. Fraternal twins are ____________.
- A. genetically identical
- B. no more alike than ordinary siblings
- C. less common than other types of multiple offspring
- D. less likely with each additional birth
Correct answer: B
Rationale: The correct answer is B. Fraternal twins are no more alike than ordinary siblings because they share about 50% of their genes, just like other siblings. Choice A is incorrect as fraternal twins are not genetically identical. Choice C is incorrect as fraternal twins are actually the most common type of multiple offspring. Choice D is incorrect as the likelihood of fraternal twins is not affected by the number of births a mother has had.
5. The __________ reflex helps a newborn find the nipple.
- A. rooting
- B. Moro
- C. Babinski
- D. tonic neck Answer: A Page Ref: 101 Skill Level: Understand Topic: The Newborn Baby’s Capacities Difficulty Level: Moderate
Correct answer: A
Rationale: The rooting reflex is the correct answer. This reflex helps a newborn baby find the nipple by turning their head and opening their mouth when their cheek is stroked or touched. This is crucial for the baby to locate and latch onto the mother's breast for feeding. The rooting reflex typically disappears around 4 months of age.
