Within-subjects design uses each participant as his or her own control by comparing the participant's performance or responses in different conditions or at different times. This design allows for the control of individual differences because the same individuals participate in all conditions.  This research design allows researchers to study the behavior of each participant in the study before getting the treatment and after.
