Human Growth and Development Exam 1
1. In a longitudinal design, participants are studied repeatedly at different ages, and changes are noted as they get older.
- A. cross-sectional
- B. experimental
- C. longitudinal
- D. correlational
Correct answer: C
Rationale: The correct answer is C: longitudinal. In a longitudinal design, participants are followed and studied over an extended period, allowing researchers to observe changes and continuity in development as individuals age. This design is crucial for understanding how individuals grow and change over time. Cross-sectional studies (Choice A) involve comparing different groups at the same time point, while experimental studies (Choice B) involve manipulating variables to observe their effects. Correlational studies (Choice D) examine relationships between variables but do not involve studying participants over time.
2. 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.
3. 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.
4. Newborns of smoking mothers __________.
- A. are more attentive to sounds
- B. display more muscle tension
- C. less often have colic
- D. are less excitable when visually stimulated Answer: B Page Ref: 84 Skill Level: Understand known or suspected teratogens. Copyright © 2018 Laura E. Berk. All Rights Reserved. 12 Test Bank for Berk, Development Through the Lifespan, 7e Topic: Prenatal Environmental Influences Difficulty Level: Moderate
Correct answer: B
Rationale: Newborns of smoking mothers display more muscle tension. This is because nicotine in cigarettes can lead to increased muscle tension in babies, which can affect their physical development and potentially lead to future health issues. This is one of the negative effects of smoking during pregnancy on the developing fetus.
5. The embryonic disk __________.
- A. becomes the new organism
- B. is the outer ring of cells on a blastocyst
- C. has a good chance of survival outside the womb
- D. is a protective membrane that surrounds the amnion Answer: A Page Ref: 77 Skill Level: Understand Topic: Prenatal Development Difficulty Level: Moderate
Correct answer: A
Rationale: The embryonic disk becomes the new organism. It is a cluster of cells within the blastocyst that will develop into the fetus during the early stages of prenatal development. This cluster of cells is responsible for giving rise to all the tissues and organs of the developing organism.
