1. What is one limitation of the ethnographic method?

• A. Investigators' cultural values sometimes lead them to misinterpret what they see.
• B. It provides little information on how children and adults actually behave.
• C. It relies on unobtrusive techniques, such as surveillance cameras and one-way mirrors.
• D. It provides little information about the reasoning behind participants' responses.

Correct answer: A

Rationale: The limitation of the ethnographic method is that investigators' cultural values sometimes lead them to misinterpret what they see. This can introduce bias into the observations and potentially impact the accuracy of the findings. It is important for researchers to be aware of their own biases and strive to minimize their influence when conducting ethnographic studies. Choice B is incorrect because ethnographic methods actually aim to provide rich information on how individuals behave within their cultural contexts. Choice C is incorrect as ethnographic methods typically involve direct observation and participation rather than unobtrusive techniques like surveillance cameras. Choice D is incorrect because one of the strengths of ethnographic research is its ability to uncover the reasoning behind participants' responses by immersing the researcher in the cultural setting.

2. Today, research that combines an experimental strategy with __________ approach is becoming increasingly common.

• A. both a correlational and a sequential
• B. either a correlational or a sequential
• C. either a longitudinal or a cross-sectional
• D. both a correlational and a longitudinal

Correct answer: C

Rationale: The blank in the statement refers to an approach that can be used in combination with an experimental strategy. Longitudinal and cross-sectional approaches are two common research methods in developmental psychology. Longitudinal studies involve following the same group of individuals over an extended period, while cross-sectional studies compare different groups of individuals of different ages at the same time. By combining an experimental strategy with either a longitudinal or a cross-sectional approach, researchers can gain a deeper understanding of developmental processes and changes over time. Choices A, B, and D are incorrect because correlational and sequential are not the most relevant approaches when studying developmental changes over time in research.

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. Which individual is most likely to experience the greatest percentage of REM sleep?

• A. Sammy, a preschool child
• B. Jake, a full-term newborn
• C. Sarah, a teenager
• D. Cheryl, a preterm newborn Answer: D Page Ref: 104 Copyright © 2018 Laura E. Berk. All Rights Reserved. 32 Test Bank for Berk, Development Through the Lifespan, 7e Skill Level: Apply Topic: The Newborn Baby’s Capacities Difficulty Level: Moderate

Correct answer: D

Rationale: Preterm newborns, like Cheryl, experience a higher percentage of REM sleep compared to full-term newborns. This is because REM sleep plays a critical role in brain development, and preterm infants have an increased need for brain development due to their early arrival. Therefore, Cheryl, as a preterm newborn, is most likely to experience the greatest percentage of REM sleep among the individuals listed.

5. Who believed that complex mental activities have their origins in social interaction?

• A. Jean Piaget
• B. Renée Baillargeon
• C. Noam Chomsky
• D. Lev Vygotsky

Correct answer: D

Rationale: The correct answer is Lev Vygotsky. Vygotsky emphasized the role of social interaction and cultural tools in the development of higher cognitive functions. Jean Piaget focused more on individual cognitive development stages, Renée Baillargeon is known for her work in infant cognition and object permanence, and Noam Chomsky is renowned for his theories in linguistics and the study of language.
