Growth and Development Exam Questions

Question 1 of 5

To overcome some of the limitations of traditional developmental designs, investigators sometimes use __________ designs, in which they conduct several similar cross-sectional or longitudinal studies.

Correct Answer: A

Rationale: Sequential designs involve conducting multiple similar cross-sectional or longitudinal studies to overcome limitations of traditional developmental designs. By combining different types of study designs, researchers can gain a more comprehensive understanding of development over time. This approach allows for more robust conclusions and can help address potential confounding variables that may impact the results.

Question 2 of 5

Which statement about interventions that support parents and preterm infants is true?

Correct Answer: B

Rationale: Babies who are both preterm and economically disadvantaged typically require long-term, intensive intervention. This is because the combination of being born preterm and being economically disadvantaged can pose significant challenges for the infant's development. Providing ongoing support and interventions can help address these challenges and promote healthy development in these infants.

Question 3 of 5

In an experimental study examining whether children who are read to more often score higher on vocabulary tests in first grade, the independent variable would be the __________.

Correct Answer: A

Rationale: In an experimental study, the independent variable is the factor being manipulated or controlled by the researcher. In this case, the frequency of read-alouds is the variable that researchers would intentionally change or vary to see its effect on the dependent variable, which is the children's vocabulary scores. The other options (B. type of books parents read, C. child's vocabulary score, and D. difficulty of vocabulary words) are not the independent variable in this study as they are either irrelevant or are the outcome being measured.

Question 4 of 5

__________ doubles the risk of SIDS.

Correct Answer: D

Rationale: Cigarette smoking by a caregiver doubles the risk of SIDS. Secondhand smoke exposure can increase the likelihood of SIDS due to the toxins and chemicals present in cigarette smoke. It is important to have a smoke-free environment for infants to reduce the risk of SIDS.

Question 5 of 5

Dr. Wu observes children's responses to bullying by watching them play in a park. This is an example of a(n) __________.

Correct Answer: B

Rationale: Dr. Wu's observation of children's responses to bullying by watching them play in a park is an example of naturalistic observation. Naturalistic observation involves observing behavior in a natural setting without any manipulation or intervention. Dr. Wu is simply observing the children's behavior in a real-world setting to gain insights into how they respond to bullying, making it a naturalistic observation.
