In a repeated measures design, there is the assumption of sphericity - this means that the variances of the differences between all possible pairs of related conditions are equal. This assumption is not a concern in a between subjects design, where the assumption of independence is typically more important. Homogeneity of variance and normality are concerns in both types of designs.
