1. Dr. Dias's research shows that the death of a spouse in old age is correlated with a decline in the surviving partner's physical health. Which conclusion is supported by this study?

• A. The death of a spouse causes a decline in the surviving partner's physical health.
• B. The death of a spouse is related to a decline in the surviving partner's physical health.
• C. A decline in a surviving partner's physical health can cause the death of a spouse.
• D. A third variable, such as memory loss, causes a surviving partner's decline in physical health following the death of a spouse.

Correct answer: B

Rationale: Dr. Dias's research findings indicate a correlation between the death of a spouse and a decline in the surviving partner's physical health. This correlation suggests a relationship between the two variables, but it does not necessarily imply a direct cause-and-effect relationship. Therefore, the correct conclusion supported by this study is option B - 'The death of a spouse is related to a decline in the surviving partner's physical health.' Option A is too direct in its causation claim, which is not proven by correlation alone. Option C reverses the cause and effect relationship suggested by the research. Option D introduces an unrelated third variable, which is not supported by the study's findings.

2. Longitudinal research can identify common patterns as well as individual differences in development because the investigator __________.

• A. studies groups of participants differing in age at the same point in time
• B. randomly assigns participants to treatment conditions
• C. tracks the performance of each person over time
• D. conducts quasi-experiments, comparing conditions that already exist

Correct answer: C

Rationale: Longitudinal research involves tracking the performance of each person over time. By doing so, researchers can observe common patterns in development among a group of individuals and also identify individual differences in how each person progresses over time. This methodology allows researchers to gather data on the same individuals repeatedly, offering insights into how development unfolds over the lifespan. Choices A, B, and D are incorrect because longitudinal research focuses on observing individuals over time rather than studying groups at a single point, randomly assigning participants to treatments, or conducting quasi-experiments.

3. In a cross-sectional design, researchers study __________.

• A. the same group of participants repeatedly at different ages
• B. groups of participants differing in age at the same point in time
• C. groups of participants of the same age in different years
• D. participants of the same age at the same point in time

Correct answer: B

Rationale: In a cross-sectional design, researchers study groups of participants differing in age at the same point in time. This design allows researchers to compare different age groups simultaneously, providing valuable insight into age-related differences without the need to track the same group over time. Choice A is incorrect because it describes a longitudinal design where the same group is followed over time. Choice C is incorrect as it involves different groups of the same age studied at different times. Choice D is incorrect as it does not capture the essence of a cross-sectional design, which involves studying groups of different ages at the same point in time.

4. Jade spent two years in a Mexican-American community studying communication between parents and children. Jade was using __________.

• A. naturalistic observation
• B. ethnography
• C. self-reports
• D. structured observation

Correct answer: B

Rationale: Jade was using ethnography. Ethnography involves the systematic study of people and cultures through participant observation and interviews. In this case, Jade spent two years in a Mexican-American community studying communication between parents and children, which aligns with the methodology of ethnography. Ethnography allows researchers to gain an in-depth understanding of a particular cultural group's behaviors, practices, and beliefs. Choice A, naturalistic observation, involves observing subjects in their natural environment without interference or manipulation. While similar to ethnography in some aspects, naturalistic observation does not typically involve the same level of cultural immersion and participant interaction as ethnography. Choice C, self-reports, refers to data collected directly from participants about their thoughts, feelings, or behaviors. This method relies on participants' subjective responses and may not provide the same depth of cultural insights as ethnography. Choice D, structured observation, involves observing behavior in a structured and controlled environment. Unlike ethnography, structured observation does not focus on the cultural nuances and immersive study of a specific community.

5. Sigmund Freud constructed his psychosexual theory __________.

• A. on the basis of his adult patients' memories of painful childhood events
• B. by conducting studies of animal behavior
• C. on the basis of interviews with institutionalized children and adolescents
• D. by carefully observing his own children

Correct answer: A

Rationale: Sigmund Freud constructed his psychosexual theory on the basis of his adult patients' memories of painful childhood events. Freud believed that events in early childhood had a significant impact on an individual's development and personality. He used his patients' recollections of childhood experiences to develop his theories on psychosexual development. Choice B is incorrect as Freud did not base his theory on studies of animal behavior. Choice C is incorrect as Freud's theory was not solely based on interviews with institutionalized children and adolescents. Choice D is incorrect as Freud did not construct his theory by observing his own children.
