Question

Quizplus · Accepted Answer

Maturation is the threat to internal validity in research conducted on children because they are still growing and developing, which can lead to changes in their behavior and abilities over time, independent of any treatment or intervention being tested. Regression to the mean refers to the phenomenon in which extreme scores on a variable tend to move closer to the average score when measured again at a later time, but this is not specific to children or research on children. History refers to external events that may occur during the course of the study that could impact the results, and placebo refers to the use of an inactive treatment to control for the effects of expectations and beliefs on outcomes, but neither of these are specifically related to children.
