1. Dr. Anodyne found a correlation of +.49 between illegal drug use and levels of adolescent delinquency. This correlation is __________ and __________.
- A. moderate; positive
- B. low; positive
- C. high; negative
- D. low; negative Answer: A Page Ref: 33 Skill Level: Apply and limitations of each. Topic: Studying Development Difficulty Level: Easy
Correct answer: A
Rationale: The correlation of +.49 indicates a moderate strength of relationship between illegal drug use and levels of adolescent delinquency. The positive correlation indicates that as one variable (illegal drug use) increases, the other variable (adolescent delinquency) also tends to increase.
2. 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.
3. By age 2, children __________.
- A. take turns in face-to-face interaction
- B. can infer a speaker's indirectly expressed intention
- C. adjust their speech to fit the age of their listeners
- D. adjust their speech to fit the social status of their listeners
Correct answer: C
Rationale: By age 2, children are capable of adjusting their speech to fit the age of their listeners, showing early social cognition. Choice A is incorrect because taking turns in face-to-face interaction typically develops later in childhood. Choice B is incorrect as the ability to infer a speaker's indirectly expressed intention is a more advanced skill not typically seen at age 2. Choice D is also incorrect as children at age 2 are not developmentally ready to adjust their speech based on the social status of their listeners.
4. Dr. McBride wants to know if the teacher's use of encouragement in the classroom affects the children's self-esteem. To assign children to treatment conditions, Dr. McBride should __________.
- A. carefully distribute the children according to their test scores
- B. divide the children so each group has an equal number of boys and girls
- C. draw the children's names out of a hat
- D. assign the quieter children to the same treatment condition
Correct answer: C
Rationale: Drawing the children's names out of a hat is a way to randomly assign them to treatment conditions. Random assignment helps to ensure that any differences in self-esteem that may be observed in the study are not due to pre-existing characteristics of the children. This method helps to establish a cause-and-effect relationship between the teacher's use of encouragement and the children's self-esteem. Choice A is incorrect because assigning children based on test scores may introduce bias into the study. Choice B is incorrect as balancing gender is not relevant to the research question. Choice D is incorrect as it introduces a bias by selecting a specific group of children based on a characteristic unrelated to the study objective.
5. 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.
