1. In field experiments, researchers __________.

• A. selectively assign participants to treatment conditions in natural settings
• B. cannot use random assignment or manipulate treatment conditions
• C. randomly assign participants to treatment conditions in natural settings
• D. have stronger control over the treatment than in the laboratory

Correct answer: C

Rationale: In field experiments, researchers randomly assign participants to treatment conditions in natural settings. This method allows for a higher level of control over potential confounding variables compared to non-random assignment. Random assignment helps ensure that the groups being compared are comparable at the beginning of the study, which strengthens the internal validity of the research findings. Choice A is incorrect because selective assignment may introduce bias. Choice B is incorrect as researchers can use random assignment in field experiments. Choice D is incorrect because field experiments typically have less control over the treatment compared to laboratory experiments.

2. Which statement provides an example of an age-graded influence?

• A. Paul learned to play the violin at a young age.
• B. Jack enjoys hiking in the mountains.
• C. Sarah prefers reading mystery novels.
• D. Alex excels in mathematics.

Correct answer: A

Rationale: The corrected statement 'Paul learned to play the violin at a young age' provides an example of an age-graded influence. This is because learning to play the violin is a behavior that is typical or expected at a certain age, reflecting how age influences individuals' experiences and development. In contrast, choices B, C, and D do not directly relate to age-graded influences. Jack's enjoyment of hiking, Sarah's preference for reading mystery novels, and Alex's proficiency in mathematics are not inherently tied to age-related developmental influences.

3. The immune response is the combined work of specialized cells that neutralize or destroy __________ in the body.

• A. T cells
• B. B cells
• C. telomeres
• D. antigens

Correct answer: D

Rationale: The correct answer is D, antigens. Antigens are substances recognized by the immune system as foreign, triggering an immune response to neutralize or destroy them. In this context, T cells and B cells are specialized cells of the immune system that respond to antigens, but they are not the substances being neutralized or destroyed. Telomeres, on the other hand, are protective structures at the end of chromosomes and are not targeted for neutralization or destruction by the immune system.

4. Dr. Torrez believes that how conflicts between biological drives and social expectations are resolved determines the person's ability to learn, to get along with others, and to cope with anxiety. Dr. Torrez accepts the __________.

• A. psychoanalytic perspective
• B. psychosocial theory
• C. cognitive-developmental theory
• D. social learning theory

Correct answer: A

Rationale: Dr. Torrez's belief about conflicts between biological drives and social expectations influencing a person's ability to learn, get along with others, and cope with anxiety aligns with the psychoanalytic perspective. This perspective, developed by Sigmund Freud, focuses on the unconscious mind, early childhood experiences, and the resolution of inner conflicts as important factors in shaping personality and behavior. The other choices are incorrect because psychosocial theory, cognitive-developmental theory, and social learning theory do not specifically focus on conflicts between biological drives and social expectations as central to understanding human behavior and development.

5. 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.
