Distribution of (a) individual audiovisual PSS in split-attention condition (PSSAV, orange) in the four experimental sessions (shades of grey). The within-individual variance across all sessions is reported with box plots with the bar as the median PSS value. Participants were sorted as a function of increasing PSS i.e. from requiring the sound to be presented first (negative PSS) to requiring the visual event to be presented first (positive PSS) to perceive audiovisual simultaneity. A significant Intra-Class Correlation (ICC) of .69 signified that, over the four experimental sessions, the within-individual PSS variance was smaller than the inter-individual variance. Distribution of (b) individual audiovisual PSS free of attentional bias (PSSfree, purple) in the four experimental sessions (shades of grey). Box plots of individual PSSfree were sorted as a function of PSSAV. As previously, the ICC of .77 signified that, over the four experimental sessions, the within-individual PSSfree variance was smaller than the inter-individual variance. The sorting of PSSAV (orange) and PSSfree (purple) showed nearly (c) the same individual ranking to the exception of individual 7. Bottom right inset: PSSAV and PSSfree were significantly correlated (R= .92, p <.001); shaded area is 95% CI *** p< .001; bars are 2 s.e.m.
