For the two-way MANOVA on θ power with group (NAC vs. LTAA) and condition (resting vs. task) as the independent variables, Levene’s test showed that the assumption of homogeneity of variance was violated for the between-subjects group variable. Therefore, separate one-way between-subject MANOVAs were carried out for each level of the condition variable, and a one-way repeated-measure MANOVA was performed for comparing conditions for the combined groups. The results are shown in Table 3.
