What are two advantages of 2 x 2 within-subjects multifactorial designs relative to 2 x 2 between-subjects multifactorial designs?

In the within-subjects designs, participants serve as their own controls, thus minimizing individual differences. Within-subjects designs are also more economical between they require fewer participants than between-subjects designs.
