Within and between group contrast (coherent > scrambled biological motion) for HbO. A(i). NAI children (n = 21) unthresholded t-map. Red regions indicate a greater response to coherent biological motion, while blue regions indicate a greater response to scrambled motion. Cluster correction revealed six regions of significant activity, visualized on the cortical A(ii) surface and within the A(iii) volume. B(i). Autistic children (n = 23) unthresholded t-map. Cluster correction results in four significant regions of contrast activity, shown on the B(ii) cortical surface and B(iii) volumetric maps. C(i). Welch-Satterthwaite corrected t-map showing NAI contrast greater than ASD. Red regions indicate greater NAI contrast activity ASD. Cluster correction revealed six significant regions visualized on the C(ii) surface and within the C(iii) volume. Cluster-corrected maps are thresholded at voxel-wise p < 0.0075 and FDR-corrected at a cluster significance of p < 0.0125)
