In a one-factor within-subjects ANOVA, MSA reflects variation in scores due to the effect of the independent variable (IV) itself, MSB reflects variation due to between-subject differences, and MSS reflects variation due to error. However, in a within-subjects design, the IV is the same for all participants, so there are no between-subject differences to account for. Therefore, the variation in scores is due to the interaction of the IV with subjects, which is captured by the term MSA × S (MSA multiplied by the mean square for subjects).
