1. In an experimental study examining whether children who are read to more often score higher on vocabulary tests in first grade, the independent variable would be the __________.

• A. frequency of read-alouds
• B. type of books parents read
• C. child’s vocabulary score Copyright © 2018 Laura E. Berk. All Rights Reserved. 31 Test Bank for Berk, Development Through the Lifespan, 7e
• D. difficulty of vocabulary words Answer: A Page Ref: 33 Skill Level: Apply and limitations of each. Topic: Studying Development Difficulty Level: Difficult

Correct answer: A

Rationale: In an experimental study, the independent variable is the factor being manipulated or controlled by the researcher. In this case, the frequency of read-alouds is the variable that researchers would intentionally change or vary to see its effect on the dependent variable, which is the children's vocabulary scores. The other options (B. type of books parents read, C. child's vocabulary score, and D. difficulty of vocabulary words) are not the independent variable in this study as they are either irrelevant or are the outcome being measured.

2. Which factor disrupts the brain's regulation of hunger and metabolism?

• A. Self-regulation
• B. Frequent eating out
• C. Reduced sleep
• D. Using screen media

Correct answer: C

Rationale: Reduced sleep is the correct answer as it affects hormones that regulate hunger and metabolism, leading to increased appetite and weight gain. Self-regulation is not directly related to the brain's regulation of hunger and metabolism. Frequent eating out may impact food choices and portion sizes but is not specifically linked to disrupting the brain's regulation. Using screen media can affect sleep patterns but is not as directly related to the brain's regulation of hunger and metabolism as reduced sleep.

3. 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.

4. Konrad Lorenz and Niko Tinbergen laid the modern foundations for __________.

• A. ethology
• B. social learning theory
• C. psychoanalytic theory
• D. cognitive-developmental theory

Correct answer: A

Rationale: Konrad Lorenz and Niko Tinbergen are considered the founders of ethology, a branch of biology and psychology that focuses on the study of animal behavior in natural environments. Their work laid the modern foundations for ethology, which examines the behavior of animals in relation to their natural habitats and evolutionary history. Choice B, social learning theory, is incorrect as it pertains to a different area of psychology that focuses on how people learn through observing others. Choice C, psychoanalytic theory, is also incorrect as it is a psychological theory developed by Sigmund Freud that emphasizes the role of unconscious conflicts in determining behavior. Choice D, cognitive-developmental theory, is incorrect as it refers to the work of Jean Piaget in understanding the development of human cognition in children.

5. Most cognitive aging research has focused on intellectual ________.

• A. stability
• B. gains
• C. competence
• D. deficits

Correct answer: D

Rationale: The correct answer is 'D: deficits.' Most cognitive aging research has indeed focused on deficits rather than stability, gains, or competence. Studies have consistently shown that deficits in processing speed and memory are common in aging individuals, making it a primary area of interest in research. Choices A, B, and C are incorrect because cognitive aging research primarily aims to understand and address deficits associated with aging rather than focusing on stability, gains, or overall competence.
