Growth and Development Exam Questions
Question 1 of 5
The two main types of designs used in all research on human behavior are __________ and __________.
Correct Answer: B
Rationale: The two main types of designs used in all research on human behavior are correlational and experimental. Correlational research examines the relationship between two or more variables without establishing causation, while experimental research involves manipulating one variable to observe the effect on another variable. These two types of designs are fundamental in understanding and studying human behavior.
Question 2 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 3 of 5
What is one strength of the cross-sectional design?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
Bernadette, a participant in a longitudinal study, became quite familiar with the test over time and, as a result, her performance improved. This limitation of longitudinal research is known as __________.
Correct Answer: B
Rationale: Practice effects refer to the phenomenon where participants in a longitudinal study show improvement in test performance over time due to becoming familiar with the tasks or test materials. This can be considered a limitation as it may distort the results by showing an artificial improvement rather than a true developmental change.
Question 5 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.
