The additional assumption that is applied to Repeated-measures factorial design is sphericity, which means that the variances of the differences between all possible pairs of treatment conditions are equal. This assumption is necessary for accurate statistical analysis, and violation of sphericity can lead to incorrect inferences and false conclusions. Therefore, choice C (sphericity) is the correct answer.
