1. In an experiment, the independent variable __________.

Correct answer: B

Rationale: In an experiment, the independent variable is the one that the investigator expects to cause changes in another variable. It is the factor that is deliberately manipulated or changed by the researcher to observe its effects on the dependent variable. The purpose of manipulating the independent variable is to study its impact on the outcome, allowing researchers to establish cause-and-effect relationships in their investigations. Choice A is incorrect because the independent variable is not influenced but rather influences another variable. Choice C is incorrect as the independent variable is intentionally manipulated by the researcher. Choice D is incorrect as it refers to a different concept unrelated to the independent variable in an experiment.

2. What did John Bowlby believe?

Correct answer: B

Rationale: John Bowlby believed that the infant-caregiver bond has lifelong consequences for human relationships. This is supported by his theory of attachment, where he emphasized the importance of early attachment experiences in shaping individuals' future relationships. Choice A is incorrect as it does not reflect Bowlby's main focus on attachment theory. Choice C is incorrect as Bowlby's theory suggests that attachment is more than just instinctual. Choice D is also incorrect as Bowlby's work actually paved the way for the study of attachment patterns in humans.

3. Pregnant women are wise to avoid eating __________, which are heavily contaminated with __________.

Correct answer: A

Rationale: Pregnant women are wise to avoid eating long-lived predatory fish, which are heavily contaminated with mercury. Mercury is a known teratogen, meaning it can negatively impact the development of the fetus and lead to birth defects. It is recommended that pregnant women choose fish with lower levels of mercury to reduce potential risks to the baby's health. Choices B, C, and D are incorrect because lead, polychlorinated biphenyls, and radiation are not typically found in fish at levels that pose significant risks to pregnant women and the developing fetus.

4. Cindy tells her daughter, “I know you can do a good job on that homework” because she believes that if she encourages persistence, her daughter will start to view herself as hardworking and high-achieving. Cindy is applying the __________ approach.

Correct answer: D

Rationale: Cindy is applying the social-cognitive approach by encouraging her daughter to believe in her own abilities and persist in her efforts. This approach emphasizes the importance of social influences and cognitive processes in shaping behavior. By providing positive reinforcement and fostering a belief in her daughter's capabilities, Cindy is helping to shape her daughter's self-perception and motivation to achieve success.

5. Which expectant mother has the greatest risk of a baby born with fetal alcohol syndrome?

Correct answer: C

Rationale: According to research, Native American populations have the highest prevalence of fetal alcohol syndrome (FAS) in the United States. This increased risk is due to various social, cultural, and environmental factors within Native American communities.
