Bar plots of looming bias for mean dominance time (s, top) and % cumulative dominance time (bottom, across subjects mean+SE).

<p>Left: Visual Shepard stimulus; Right: Visual starfield. The type of auditory stimulation is colour coded (see legend). Please note that the looming bias differs for mean dominance times (in seconds) and % cumulative dominance times (i.e. fraction of total dominance duration for looming or receding percept and the total duration of presentation time) because of additional piecemeal periods.
