1. Bernadette, a participant in a longitudinal study, became quite familiar with the test over time and, as a result, her performance improved. This limitation of longitudinal research is known as __________. Copyright © 2018 Laura E. Berk. All Rights Reserved. 34 Test Bank for Berk, Development Through the Lifespan, 7e

• A. biased sampling
• B. practice effects
• C. random assignment
• D. cohort effects Answer: B Page Ref: 35 Skill Level: Apply Topic: Studying Development Difficulty Level: Moderate

Correct answer: B

Rationale: Practice effects refer to the phenomenon where participants in a longitudinal study show improvement in test performance over time due to becoming familiar with the tasks or test materials. This can be considered a limitation as it may distort the results by showing an artificial improvement rather than a true developmental change.

2. According to ecological systems theory, interactions between Marina and her child, Tyler, occur in the __________. Copyright © 2018 Laura E. Berk. All Rights Reserved. 20 Test Bank for Berk, Development Through the Lifespan, 7e

• A. microsystem
• B. mesosystem
• C. exosystem
• D. macrosystem Answer: A Page Ref: 23 Skill Level: Apply Topic: Recent Theoretical Perspectives Difficulty Level: Moderate

Correct answer: A

Rationale: According to ecological systems theory, interactions between Marina and her child, Tyler, occur in the microsystem. The microsystem refers to the immediate social context in which an individual lives, such as interactions with family members, friends, and teachers. Marina and Tyler's interactions within their family unit would be considered part of the microsystem.

3. Dr. Bigelow is interested in studying musical prodigies. Which method is best suited for this type of research?

• A. naturalistic observation
• B. clinical interview
• C. case study
• D. structured interview

Correct answer: C

Rationale: A case study would be the best method for Dr. Bigelow to study musical prodigies. In a case study, the researcher can closely examine and analyze the unique characteristics, abilities, and behaviors of individual subjects. This method allows for in-depth exploration of a specific phenomenon, making it ideal for investigating exceptional cases such as musical prodigies. Naturalistic observation involves observing subjects in their natural environment without interference, which may not provide the detailed insights needed for studying musical prodigies. Clinical interviews focus on gathering information through structured questioning, not ideal for studying unique talents. Structured interviews involve asking a set of predetermined questions, which may not allow for the depth of exploration required for studying musical prodigies.

4. Newborn Mariana, who reacts strongly to unpleasant stimuli, is __________.

• A. probably easy to console
• B. susceptible to colic
• C. likely to spend less time in REM sleep
• D. unlikely to respond to swaddling

Correct answer: B

Rationale: Newborn Mariana, who reacts strongly to unpleasant stimuli, is described as susceptible to colic. Colic is often characterized by excessive crying and fussiness in newborn babies, which can be challenging to console. This description suggests that Mariana's strong reactions to unpleasant stimuli may make her more prone to colic. Choices A, C, and D are incorrect because the strong reactions to unpleasant stimuli do not imply being easy to console, affect REM sleep, or responsiveness to swaddling.

5. Which statement about the human immunodeficiency virus (HIV) is true?

• A. About 30 percent of all new HIV infections affect women.
• B. In South Africa, 30 percent of all pregnant women are HIV-positive.
• C. About 30 percent of new HIV infections occur in developing countries.
• D. Untreated HIV-infected mothers pass the virus to the fetus 30 percent of the time.

Correct answer: B

Rationale: The correct answer is B: 'In South Africa, 30 percent of all pregnant women are HIV-positive.' This statement is true as South Africa has a high prevalence of HIV among pregnant women, emphasizing the need for interventions to prevent mother-to-child transmission. Choices A, C, and D are incorrect. Choice A is inaccurate as women account for more than 50% of new HIV infections globally. Choice C is misleading as the majority of new HIV infections actually occur in sub-Saharan Africa, not just developing countries. Choice D is also incorrect as without treatment, the risk of mother-to-child transmission is higher than 30%.
