Results of ANOVAs computed on midline and lateral electrodes for main effects, 2-way and 3-way interactions. Only significant effects (p<0.05) are shown. Abbreviations: df, degrees of freedom; T, Attentional Task; W, Word; M, Melody; H, Hemisphere; R, Region.

† Pairwise comparisons of interest did not meet the criteria for Bonferroni significance and thus the interaction is not discussed further in the text.
