Maturation as a threat to internal validity in experiments refers to _____.

Question

Quizplus · Accepted Answer

Maturation refers to changes that occur in the subjects over time, which can impact the results of the experiment. This is a threat to internal validity because it becomes difficult to determine if the changes in the outcome variable were due to the manipulation of the independent variable or simply due to the natural maturation process of the subjects. To minimize this threat, researchers might use a control group that does not receive the intervention to compare the changes seen in the experimental group.
