A within-subjects methodology involves the same subjects being exposed to all conditions or treatments of the experiment. A two-group design typically involves different subjects in each group (making it a between-subjects design), whereas repeated measures, mixed designs, and pretest-posttest designs all involve measuring the same subjects under different conditions or at different times, fitting the within-subjects methodology.
