Which research design controls for maturation as a threat to internal validity?

Question

Quizplus · Accepted Answer

The comparison group design controls for maturation as a threat to internal validity by comparing changes in a group receiving an intervention to changes in a group not receiving the intervention, thus allowing researchers to distinguish between effects due to the intervention and effects due to maturation. The one-group pretest-posttest design does not control for maturation because it does not include a comparison group to differentiate between the effects of maturation and the intervention.
