1. In an experimental study examining whether the way angry encounters end affects children's emotional reactions, the dependent variable would be the __________.

• A. way the angry encounters end
• B. amount of unresolved anger
• C. frequency of angry encounters
• D. children's emotional reactions

Correct answer: D

Rationale: In an experimental study examining whether the way angry encounters end affects children's emotional reactions, the dependent variable would be the children's emotional reactions. The dependent variable is the outcome being measured or tested in an experiment. In this study, the researchers are trying to understand how the way angry encounters end influences children's emotions. Therefore, the emotional reactions of the children would be the dependent variable that is being studied and measured in relation to the way angry encounters end. Choices A, B, and C are not the dependent variable in this scenario. While they may be related factors, the main focus of the study is on how the way angry encounters end impacts children's emotional reactions, making children's emotional reactions the dependent variable.

2. Dr. Faulkner believes that directly observable events, such as stimuli and responses, are the appropriate focus of the study of development. Dr. Faulkner probably follows the __________ perspective of development.

• A. psychosexual
• B. psychosocial
• C. behaviorist
• D. cognitive-developmental

Correct answer: C

Rationale: Dr. Faulkner's focus on directly observable events, such as stimuli and responses, aligns with the behaviorist perspective of development. Behaviorism emphasizes the influence of the environment on individual behavior and learning, with a strong emphasis on observable actions rather than internal mental processes or stages of development. Choice A, psychosexual, is associated with Freud's theory focusing on stages of psychosexual development. Choice B, psychosocial, is linked to Erikson's theory of psychosocial development. Choice D, cognitive-developmental, is related to Piaget's theory emphasizing cognitive development stages.

3. In an experiment, the independent variable __________.

• A. is the one the investigator expects to be influenced by another variable
• B. is the one the investigator expects to cause changes in another variable
• C. cannot be manipulated or controlled by the researcher
• D. is the number that describes how two measures are associated with each other

Correct answer: B

Rationale: In an experiment, the independent variable is the one that the investigator expects to cause changes in another variable. It is the factor that is deliberately manipulated or changed by the researcher to observe its effects on the dependent variable. The purpose of manipulating the independent variable is to study its impact on the outcome, allowing researchers to establish cause-and-effect relationships in their investigations. Choice A is incorrect because the independent variable is not influenced but rather influences another variable. Choice C is incorrect as the independent variable is intentionally manipulated by the researcher. Choice D is incorrect as it refers to a different concept unrelated to the independent variable in an experiment.

4. Which statement about prenatal rubella is true?

• A. The greatest damage occurs when rubella strikes during the fetal period.
• B. The organ damage inflicted by prenatal rubella can lead to lifelong health problems. Copyright © 2018 Laura E. Berk. All Rights Reserved. 15 Test Bank for Berk, Development Through the Lifespan, 7e
• C. Routine vaccination has made new rubella outbreaks extremely rare worldwide.
• D. Infection during the embryonic period is less harmful than during other prenatal periods. Answer: B Page Ref: 86‒87 Skill Level: Understand known or suspected teratogens. Topic: Prenatal Environmental Influences Difficulty Level: Moderate

Correct answer: B

Rationale: The statement that the organ damage inflicted by prenatal rubella can lead to lifelong health problems is true. Rubella infection during pregnancy can cause serious harm to the developing fetus, including organ damage, deafness, heart defects, and intellectual disabilities. This highlights the importance of prevention and vaccination to protect both pregnant women and their unborn babies from the harmful effects of rubella.

5. Lanugo ________.

• A. permits food and oxygen to reach the organism
• B. provides the fetus a cushion against jolts caused by the mother's movements
• C. helps regulate the fetus's body temperature
• D. helps the vernix stick to the skin

Correct answer: D

Rationale: Lanugo helps the vernix stick to the skin. Vernix is a waxy substance that covers the fetus's skin during pregnancy. Lanugo is a fine, downy hair that helps to anchor the vernix to the skin, providing protection and nourishment to the developing fetus. Choices A, B, and C are incorrect as they do not accurately describe the role of lanugo in prenatal development.
