Graphs of amplitude (mean fit coefficient) (A) and extent (volume in µl of active voxels with t > 2.0) (B) of brain response within the cluster of significant group difference in brain response to all speech in the left hemisphere superior temporal gyrus. Values are shown for all speech (used to identify the significant cluster) and separately for the component conditions. Mean values for the autism spectrum disorder (ASD) group are shown in red and those for the typically developing group are shown in blue. Error bars indicate the standard error of the mean.
