Human Growth and Development Exam Questions
1. Observations of imprinting led to which major concept in human development?
- A. adaptation
- B. equilibrium
- C. the critical period
- D. classical conditioning
Correct answer: C
Rationale: Observations of imprinting in animals, such as ducklings following the first moving object they see after hatching, led to the major concept of the critical period in human development. The critical period is a specific time frame during which an organism must experience certain stimuli to develop properly. This concept has been influential in understanding various aspects of human development, such as language acquisition and social attachment. Choices A, B, and D are incorrect. Adaptation refers to adjusting to the environment, equilibrium is about balance in cognitive processes, and classical conditioning is a learning process associated with behaviorism, none of which directly relate to the concept derived from imprinting observations.
2. Pregnant women are wise to avoid eating __________, which are heavily contaminated with __________.
- A. long-lived predatory fish; mercury
- B. freshwater fish; lead
- C. long-lived predatory fish; polychlorinated biphenyls
- D. freshwater fish; radiation
Correct answer: A
Rationale: Pregnant women are wise to avoid eating long-lived predatory fish, which are heavily contaminated with mercury. Mercury is a known teratogen, meaning it can negatively impact the development of the fetus and lead to birth defects. It is recommended that pregnant women choose fish with lower levels of mercury to reduce potential risks to the baby's health. Choices B, C, and D are incorrect because lead, polychlorinated biphenyls, and radiation are not typically found in fish at levels that pose significant risks to pregnant women and the developing fetus.
3. Dr. George predicted that positive reinforcement would increase prosocial behavior in preschoolers. Dr. George's prediction is an example of a __________.
- A. theory
- B. research question
- C. hypothesis
- D. research design
Correct answer: C
Rationale: Dr. George's prediction that positive reinforcement would increase prosocial behavior in preschoolers is an example of a hypothesis. A hypothesis is a specific, testable prediction about the relationship between variables based on existing knowledge or theories. In this case, Dr. George is making a prediction about the effect of positive reinforcement on prosocial behavior, which can be tested through research. Choice A, 'theory,' is incorrect because a theory is a broader explanation that integrates a range of findings and observations. Choice B, 'research question,' is incorrect as it refers to an inquiry that asks about the relationship between variables but lacks the specificity and testability of a hypothesis. Choice D, 'research design,' is incorrect as it pertains to the overall strategy or plan for conducting a research study, not the specific prediction Dr. George made.
4. 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.
5. It is difficult to isolate the precise damage caused by illegal drugs during pregnancy because __________.
- A. most drug-using mothers refuse to participate in teratology research
- B. the majority of babies born to drug-using mothers do not survive for more than a few days
- C. most drug-using mothers quit using illegal drugs during the first trimester of pregnancy
- D. drug users often take several drugs, display other high-risk behaviors, and suffer from other stresses
Correct answer: D
Rationale: The difficulty in isolating the precise damage caused by illegal drugs during pregnancy is due to the fact that drug users often take several drugs, display other high-risk behaviors, and suffer from other stresses. This makes it challenging to identify the specific impact of each individual factor on prenatal development. Choices A, B, and C are incorrect because they do not address the complexity of the situation involving drug users during pregnancy. Most drug-using mothers refusing to participate in teratology research, the majority of babies not surviving, or drug-using mothers quitting during the first trimester do not directly explain the difficulty in isolating the precise damage caused by illegal drugs during pregnancy.
