A) Main effect of categorization > listening (red) and Effect 2 of interaction of presentation rate and word processing (blue) overlaid on coronal slices of the group's mean brain (neurological convention). Statistical maps thresholded at p < 0.05 (see Table 3). B) Post-hoc test for interactioneffect within significant clusters (Blue cluster in Fig. 4A). Effect of increased response for semantic categorization with increased presentation rate (red) and overlap (green) with areas also showing an effect of decreased response with increased presentation rate during passive listening (see Table 5).
