1. Dr. McBride wants to know if the teacher's use of encouragement in the classroom affects the children's self-esteem. To assign children to treatment conditions, Dr. McBride should __________.

• A. carefully distribute the children according to their test scores
• B. divide the children so each group has an equal number of boys and girls
• C. draw the children's names out of a hat
• D. assign the quieter children to the same treatment condition

Correct answer: C

Rationale: Drawing the children's names out of a hat is a way to randomly assign them to treatment conditions. Random assignment helps to ensure that any differences in self-esteem that may be observed in the study are not due to pre-existing characteristics of the children. This method helps to establish a cause-and-effect relationship between the teacher's use of encouragement and the children's self-esteem. Choice A is incorrect because assigning children based on test scores may introduce bias into the study. Choice B is incorrect as balancing gender is not relevant to the research question. Choice D is incorrect as it introduces a bias by selecting a specific group of children based on a characteristic unrelated to the study objective.

2. Katie wonders when she will first be able to hear her fetus's heartbeat through a stethoscope. You tell her that this should happen by the __________.

• A. fourth week of pregnancy
• B. third month of pregnancy
• C. end of the second trimester
• D. beginning of the third trimester

Correct answer: B

Rationale: The correct answer is the third month of pregnancy (choice B). During the third month of pregnancy, which is around 9-12 weeks, a fetal heartbeat can typically be heard using a stethoscope. This is an exciting milestone for expectant parents as it provides reassurance about the baby's well-being. Choices A, C, and D are incorrect because by the fourth week of pregnancy, the fetal heartbeat is not usually detectable with a stethoscope. The end of the second trimester and the beginning of the third trimester are too late in the pregnancy timeline for this milestone.

3. In the United States, the second leading cause of neonatal mortality is __________, which is largely preventable.

• A. malnutrition
• B. physical abnormality
• C. low birth weight
• D. sudden infant death syndrome

Correct answer: C

Rationale: The second leading cause of neonatal mortality in the United States is low birth weight, which is largely preventable through proper prenatal care, nutrition, and health interventions. Low birth weight infants are at higher risk for various health complications and mortality, making it an important issue to address in maternal and child health programs. Malnutrition (choice A) can contribute to low birth weight but is not the direct cause of neonatal mortality. Physical abnormality (choice B) can be a factor in some cases but is not the second leading cause overall. Sudden infant death syndrome (choice D) refers to unexplained deaths of seemingly healthy babies and is not related to low birth weight as a leading cause of neonatal mortality.

4. Increasingly, researchers __________.

• A. assume that development stops at adolescence
• B. view old age as a period of decline
• C. view heredity as more influential than the environment
• D. see development as a perpetually ongoing process Answer: D Page Ref: 7 Skill Level: Understand Topic: The Lifespan Perspective: A Balanced Point of View Difficulty Level: Moderate Copyright © 2018 Laura E. Berk. All Rights Reserved. 4 Test Bank for Berk, Development Through the Lifespan, 7e

Correct answer: D

Rationale: Increasingly, researchers see development as a perpetually ongoing process. This perspective emphasizes that development continues throughout the lifespan, rather than stopping at a particular age like adolescence. Researchers now focus on understanding how individuals change and grow over time, recognizing that development is a lifelong journey influenced by both biological and environmental factors.

5. The harm done by teratogens __________.

• A. is straightforward and predictable
• B. is usually apparent at birth
• C. rarely goes beyond physical damage
• D. depends on age at the time of exposure

Correct answer: D

Rationale: The harm done by teratogens depends on the age at the time of exposure. This means that the effects may vary depending on the developmental stage of the fetus when exposed to the teratogen. Teratogens can have different impacts at different stages of pregnancy, leading to a range of potential outcomes in terms of physical and/or cognitive development. Choices A, B, and C are incorrect because the harm caused by teratogens is not straightforward, may not be apparent at birth, and can go beyond physical damage, affecting cognitive development as well.
