a Predicted benefits versus empirical benefits for NT (left panel) and ASD (right panel) participants. Each datapoint represents the AUC of an individual participant and age group is indicated by colour. Solid lines represent linear fits to the data by age group. b Pearson correlation coefficient (r) of the regression fits in a. Asterisks indicate significant correlations (p < 0.05, two-tailed permutation tests). c, d Hypothetical models of multisensory competition were tested. Model 1A was biased towards the auditory modality and Model 1V towards the visual modality (Eq. 6). Model 2A was biased towards the preceding modality and the A modality when preceded by an AV trial, and Model 2V was biased towards the preceding modality and the V modality when preceded by an AV trial (Eq. 7). The probability p of multisensory processing being facilitative (race model) or competitive (bias model) was parametrically varied between 0 and 1 in increments of 0.25 (Eq. 8). The ability of the models to predict empirical benefits was assessed within each age group based on the Pearson correlation coefficient. Data presented are the two younger age groups. See Supplementary Fig. 4 for the two older age groups.
