Fig. 4: Impact of perceptual and semantic features on ISC.

a,b, Model-mediated ISC across TD and SD participants in the A versus V condition for the low-level model, based on the movie acoustic and visual properties (P < 0.05, one-tailed, FWEc, minimum cluster size of 20 adjacent voxels). c,d, Model-mediated ISC across TD and SD individuals in the A versus V condition for the high-level model, based on semantic features (that is, categorical information and GPT-3 features, P < 0.05, one-tailed FWEc, minimum cluster size of 20 adjacent voxels). e,f, Results of a Wilcoxon signed rank test comparing the low- and high-level models in TD and SD participants separately (P < 0.05, two-tailed, FWEc). g,h, ISC for the groups of TD and SD individuals in the A versus V condition during the processing of the scrambled movie (P < 0.05, one-tailed, FWEc, minimum cluster size of 20 adjacent voxels). Note that only the temporo-parietal cortex is mapped, since we do not find any significant results in frontal areas for the SD group in any of the explored conditions.
