1. Maryann is pregnant and works in a smoke-filled environment. What can you tell her about passive smoking?

A. The negative effects of smoking are only evident in children born to heavy smokers.
B. Passive smoking is related to low birth weight, infant death, and childhood respiratory illnesses.
C. Smoke-filled environments are harmful to expectant mothers, but not to their unborn children.
D. The effects of passive smoking are not yet known.

Correct answer: B

Rationale: Passive smoking, also known as secondhand smoke, can have harmful effects on pregnancies. Research has shown that exposure to smoke-filled environments during pregnancy is linked to low birth weight, infant death, and childhood respiratory illnesses. Pregnant women should avoid exposure to secondhand smoke to protect the health of their unborn babies. Choice A is incorrect because passive smoking affects both the mother and the unborn child, not just children born to heavy smokers. Choice C is incorrect as it underestimates the risks of smoke-filled environments on unborn children. Choice D is incorrect as research has already established the harmful effects of passive smoking on pregnancies.

2. What is one limitation of the ethnographic method?

A. Investigators' cultural values sometimes lead them to misinterpret what they see.
B. It provides little information on how children and adults actually behave.
C. It relies on unobtrusive techniques, such as surveillance cameras and one-way mirrors.
D. It provides little information about the reasoning behind participants' responses.

Correct answer: A

Rationale: The limitation of the ethnographic method is that investigators' cultural values sometimes lead them to misinterpret what they see. This can introduce bias into the observations and potentially impact the accuracy of the findings. It is important for researchers to be aware of their own biases and strive to minimize their influence when conducting ethnographic studies. Choice B is incorrect because ethnographic methods actually aim to provide rich information on how individuals behave within their cultural contexts. Choice C is incorrect as ethnographic methods typically involve direct observation and participation rather than unobtrusive techniques like surveillance cameras. Choice D is incorrect because one of the strengths of ethnographic research is its ability to uncover the reasoning behind participants' responses by immersing the researcher in the cultural setting.

3. Adolescent children of mothers who were home-visited as part of the Nurse-Family Partnership __________ than comparison-group agemates.

A. scored lower in impulsivity and overactivity
B. had lower academic achievement scores
C. showed more aggressive behavior
D. reported less alcohol and drug use

Correct answer: D

Rationale: Adolescent children of mothers who were home-visited as part of the Nurse-Family Partnership reported less alcohol and drug use compared to their comparison-group agemates. This indicates that the program may have a positive impact in reducing risky behaviors among adolescents whose mothers received home visits. Choices A, B, and C are incorrect because the extract specifically mentions that the children reported less alcohol and drug use, and there is no mention of impulsivity, overactivity, academic achievement scores, or aggressive behavior in this context.

4. In an experimental study examining whether the way angry encounters end affects children's emotional reactions, the dependent variable would be the __________.

A. way the angry encounters end
B. amount of unresolved anger
C. frequency of angry encounters
D. children's emotional reactions

Correct answer: D

Rationale: In an experimental study examining whether the way angry encounters end affects children's emotional reactions, the dependent variable would be the children's emotional reactions. The dependent variable is the outcome being measured or tested in an experiment. In this study, the researchers are trying to understand how the way angry encounters end influences children's emotions. Therefore, the emotional reactions of the children would be the dependent variable that is being studied and measured in relation to the way angry encounters end. Choices A, B, and C are not the dependent variable in this scenario. While they may be related factors, the main focus of the study is on how the way angry encounters end impacts children's emotional reactions, making children's emotional reactions the dependent variable.

5. What did Ivan Pavlov discover?

A. observational learning
B. classical conditioning
C. the ego's positive contributions to development
D. the clinical method

Correct answer: B

Rationale: Ivan Pavlov discovered classical conditioning. This is a form of learning in which a neutral stimulus becomes associated with a meaningful stimulus and acquires the capacity to elicit a similar response. Pavlov's famous experiment with dogs, where he conditioned them to salivate at the sound of a bell, demonstrated this principle. Choices A, C, and D are incorrect because Pavlov's work primarily focused on classical conditioning, not observational learning, ego contributions to development, or the clinical method.
