↵ a A repeated-measures ANOVA was conducted with time (4-10 sec after the target onset) and shift event (shift from audition to vision and shift from vision to audition) as within-subject factors and percentage of signal change as the dependent measure. The ANOVA revealed a significant main effect of time (F(4,40) = 7.82; p < 0.001) and a trend for a significant interaction (F(4,40) = 2.35; p = 0.07). This interaction was primarily driven by the difference evident at the 7 sec time point. The same analysis in the inferior parietal lobe and superior frontal sulcus/precentral gyrus yielded no significant interaction.
