1. School-age children master concrete operational tasks ________.

• A. all at once
• B. gradually, in a continuum of acquisition
• C. much later than Piaget believed
• D. after they master abstract thinking

Correct answer: B

Rationale: Correct answer: School-age children master concrete operational tasks gradually, in a continuum of acquisition. Piaget's theory suggests that children develop cognitive abilities in stages, with concrete operational tasks being acquired gradually as part of this process. Choices A, C, and D are incorrect because concrete operational tasks are not typically mastered all at once, much later than Piaget believed, or necessarily after mastering abstract thinking.

2. In his research study, Dr. Johnson gives participants false feedback about their performance. Consequently, Dr. Johnson should use __________ after the research session is over. Copyright © 2018 Laura E. Berk. All Rights Reserved. 37 Test Bank for Berk, Development Through the Lifespan, 7e

• A. informed consent
• B. a privacy statement
• C. debriefing
• D. a placebo Answer: C Page Ref: 39 Skill Level: Apply Topic: Ethics in Lifespan Research Difficulty Level: Moderate

Correct answer: C

Rationale: Dr. Johnson should use debriefing after the research session is over because giving participants false feedback may have affected them psychologically. Debriefing involves explaining the true nature of the study, including any deception that occurred, to the participants in order to protect their well-being and address any lingering concerns or misconceptions they may have. It is an important ethical practice in research to ensure participants are fully informed about the study they were involved in.

3. Like longitudinal research, cross-sectional studies can be threatened by __________.

• A. practice effects
• B. participant dropout
• C. sequential timing
• D. cohort effects

Correct answer: D

Rationale: Cross-sectional studies can be threatened by cohort effects because different age groups may have experienced different historical or social contexts, influencing the results. This disparity can lead to invalid comparisons between age groups, confounding the study's findings. Option A, practice effects, refer to changes in participants' behavior due to repeated testing, not a specific threat to cross-sectional studies. Participant dropout (Option B) is a threat related to attrition in longitudinal studies, not cross-sectional studies. Sequential timing (Option C) does not pose a threat to cross-sectional studies; instead, it refers to the order of tasks in a study design.

4. Dr. Anodyne found a correlation of +.49 between illegal drug use and levels of adolescent delinquency. This correlation is __________ and __________.

• A. moderate; positive
• B. low; positive
• C. high; negative
• D. low; negative Answer: A Page Ref: 33 Skill Level: Apply and limitations of each. Topic: Studying Development Difficulty Level: Easy

Correct answer: A

Rationale: The correlation of +.49 indicates a moderate strength of relationship between illegal drug use and levels of adolescent delinquency. The positive correlation indicates that as one variable (illegal drug use) increases, the other variable (adolescent delinquency) also tends to increase.

5. Maternal high blood glucose _________.

• A. can cause Rh factor incompatibility
• B. is linked to poorer memory in early childhood
• C. is linked to low birth weight
• D. can cause the mother's blood pressure to increase sharply

Correct answer: B

Rationale: Maternal high blood glucose is linked to poorer memory in early childhood. Research has shown that exposure to high levels of maternal blood glucose during pregnancy may negatively impact a child's memory development in early childhood. This highlights the importance of managing blood glucose levels during pregnancy for the health and development of the child. Choices A, C, and D are incorrect because they do not reflect the established link between maternal high blood glucose and poorer memory in early childhood. Rh factor incompatibility is related to blood type differences between the mother and the fetus, low birth weight can be linked to various factors other than maternal blood glucose, and sharp increases in the mother's blood pressure are not directly associated with maternal high blood glucose.
