1. 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.

2. 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.

3. The more a mental ability depends on __________ intelligence, the earlier it starts to decline.

• A. fluid
• B. crystallized
• C. emotional
• D. cultural

Correct answer: A

Rationale: The correct answer is A: fluid. Fluid intelligence, which involves problem-solving and reasoning, tends to decline earlier than crystallized intelligence. Crystallized intelligence, on the other hand, involves knowledge and skills acquired over time and is more stable with age. Emotional intelligence and cultural intelligence are not directly related to the decline of mental abilities mentioned in the question, making them incorrect choices.

4. Most cognitive aging research has focused on intellectual ________.

• A. stability
• B. gains
• C. competence
• D. deficits

Correct answer: D

Rationale: The correct answer is 'D: deficits.' Most cognitive aging research has indeed focused on deficits rather than stability, gains, or competence. Studies have consistently shown that deficits in processing speed and memory are common in aging individuals, making it a primary area of interest in research. Choices A, B, and C are incorrect because cognitive aging research primarily aims to understand and address deficits associated with aging rather than focusing on stability, gains, or overall competence.

5. Dr. O'Connor wants 90-year-old Mr. Takashi to participate in a research study that involves moderate risks. Mr. Takashi is incapable of consenting. Which statement best expresses your advice regarding Mr. Takashi's participation in the study?

• A. He should not be allowed to participate in the study under any circumstances.
• B. He should be allowed to participate in the study regardless of the benefit.
• C. He should be allowed to participate in the study only if his participation will benefit others.
• D. He should be allowed to participate in the study only if it is likely to benefit him directly.

Correct answer: D

Rationale: Mr. Takashi should be allowed to participate in the study only if it is likely to benefit him directly. This decision aligns with the principle of beneficence in research ethics, which emphasizes maximizing benefits and minimizing risks for research participants. Since Mr. Takashi is incapable of giving consent, his participation should be based on the likelihood of direct benefits to him rather than solely for the benefit of others or solely for research purposes. Option A is too restrictive and does not consider potential benefits to Mr. Takashi. Option B is flawed as it disregards the need for the study to benefit Mr. Takashi. Option C focuses on benefiting others, which is not the primary consideration when the participant cannot give consent.
