Growth and Development Exam

1. The yolk sac __________.

Correct answer: C

Rationale: The yolk sac is an extraembryonic membrane that plays a significant role in the early development of the embryo. One of its functions is to produce blood cells until the organs are mature enough to take over this function. This process occurs during the early stages of prenatal development to support the growing embryo before it can sustain itself independently.

2. According to operant conditioning theory, __________.

Correct answer: D

Rationale: According to operant conditioning theory, the frequency of a behavior can be increased by following it with a wide variety of reinforcers. In operant conditioning, behaviors are shaped through reinforcement, which can be positive (rewarding) or negative (removal of something unpleasant). By providing reinforcement following a behavior, the likelihood of that behavior occurring again in the future is increased. This supports the notion that the frequency of a behavior can be increased by using reinforcers in operant conditioning. Choices A, B, and C are incorrect because operant conditioning focuses on the relationship between behavior and its consequences through reinforcement (positive or negative) to increase the likelihood of the behavior recurring, rather than punishment, cultural influences, or the development of the id based on societal values.

3. What is largely responsible for the worldwide rise in cesarean deliveries?

Correct answer: C

Rationale: Medical control over childbirth is largely responsible for the worldwide rise in cesarean deliveries. Cesarean deliveries are often performed due to various medical interventions such as monitoring the progress of labor, fetal distress, and other complications that may arise during childbirth. The increasing use of medical interventions and technology has contributed to the higher rate of cesarean deliveries globally. Choices A, B, and D are incorrect because they do not directly involve the decision-making and interventions typically carried out by medical professionals during childbirth, which are major factors leading to the rise in cesarean deliveries.

4. Regarding a baby’s adaptation to labor and delivery, stress hormones __________. Copyright © 2018 Laura E. Berk. All Rights Reserved. 21 Test Bank for Berk, Development Through the Lifespan, 7e

Correct answer: B

Rationale: Stress hormones during labor and delivery actually help arouse the infant into alertness. These hormones can promote the infant's readiness to adapt to the new environment outside the womb.

5. Although Justin spent his first 18 months in an orphanage, his adoptive mother believes that sensitive caregiving will help Justin overcome his early experiences. Justin's mother emphasizes the role of __________ in development.

Correct answer: A

Rationale: The correct answer is A, nurture. Nurture refers to the environmental influences that shape behavior and development. In this scenario, Justin's adoptive mother believes that providing sensitive caregiving will override the negative effects of his early experiences in the orphanage, highlighting the importance of nurture in promoting healthy development. Choice B, stages, is incorrect as it refers to the sequence of developmental milestones individuals pass through. Choice C, stability, is incorrect as it pertains to the consistency of behavior or development over time. Choice D, nature, is incorrect as it relates to genetic and biological factors influencing development, which is not the focus of Justin's mother's beliefs.
