Attentional modulation of ISC depends on narrative coherence and differs by component. Top, For the auditory stimuli with no narrative (PMsc and Jpn), the first component dominates the overall ISC. Strongest attentional modulation of ISC is observed for the second component, in particular for the narrative stimulus (PM) (solid and dashed correspond to attend and count conditions). For the non-narrative stimuli, ISC is at chance levels (marked by dark-shaded bars) for the third component. Bottom, Scalp topographies (“forward model”) indicate that each component captures a different neural process. These topographies for audio-only stimuli are similar to those found previously in audiovisual stimuli (Dmochowski et al., 2012, 2014).
