Violations of the assumption of sphericity lead to increased Type I error. Sphericity refers to the assumption that the variances of the differences between all possible combinations of conditions are equal. When this assumption is violated, the Type I error rate can be inflated, meaning that the probability of falsely rejecting the null hypothesis increases. Violations of normality assumptions can lead to Type II errors, which refer to the probability of failing to reject the null hypothesis when it is actually false.
