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. Erikson believed that successful resolution of intimacy versus isolation prepares the individual for the middle adulthood stage, which focuses on __________.

• A. initiative
• B. autonomy
• C. generativity
• D. industry

Correct answer: C

Rationale: Erikson's theory of psychosocial development highlights generativity as the central focus of middle adulthood. Generativity involves being productive, caring for others, and contributing to society. This stage is characterized by a desire to leave a lasting impact on future generations. Choices A, B, and D are incorrect. Initiative is associated with the preschool years, autonomy with early childhood, and industry with middle childhood according to Erikson's stages of development.

3. What is a major disadvantage of cross-sectional research?

• A. Age-related changes cannot be examined.
• B. Participants often drop out before the study is over.
• C. Factors affecting individual development cannot be explored.
• D. Practice effects often cause biased findings.

Correct answer: C

Rationale: One major disadvantage of cross-sectional research is that factors affecting individual development cannot be explored thoroughly. Cross-sectional research involves comparing different groups of people at one specific point in time, and does not allow for tracking individual changes over time. This limitation means that the unique influences and trajectories of individual development may be overlooked in cross-sectional studies. Choices A, B, and D are incorrect. Choice A is not a major disadvantage of cross-sectional research as age-related changes can still be compared across different groups in this type of study. Choice B, while a potential issue in any study, is not specific to cross-sectional research. Choice D refers to a different type of bias caused by repeated testing rather than a major disadvantage of cross-sectional research.

4. What did John Bowlby believe?

• A. Adults and more expert peers help children master culturally meaningful activities.
• B. The infant-caregiver bond has lifelong consequences for human relationships.
• C. Parents and infants are both instinctively attached to each other.
• D. Attachment patterns are difficult to study in humans.

Correct answer: B

Rationale: John Bowlby believed that the infant-caregiver bond has lifelong consequences for human relationships. This is supported by his theory of attachment, where he emphasized the importance of early attachment experiences in shaping individuals' future relationships. Choice A is incorrect as it does not reflect Bowlby's main focus on attachment theory. Choice C is incorrect as Bowlby's theory suggests that attachment is more than just instinctual. Choice D is also incorrect as Bowlby's work actually paved the way for the study of attachment patterns in humans.

5. The most rapid prenatal changes take place in the period of the __________.

• A. zygote
• B. blastocyst
• C. embryo
• D. fetus

Correct answer: C

Rationale: The correct answer is C: embryo. The most rapid prenatal changes occur during the embryo stage, which spans from approximately 2 to 8 weeks after conception. This period is crucial as major organs and systems of the body develop rapidly, laying the foundation for future growth and development. The zygote stage is the initial single-celled entity formed by the union of sperm and egg, while the blastocyst stage involves the cluster of cells resulting from the zygote dividing and growing. The fetus stage follows the embryo stage and focuses on refining and growing existing structures rather than rapid development. Therefore, the embryo stage is where the most significant and rapid changes take place in prenatal development.
