Fig. 5

The differences in alpha PSD between the ASD and TD groups. (A) The alpha PSD of children in three groups. (B) Correlations between verbal IQ and PSD. (C) Correlations between verbal IQ and PSD residuals following partial SIC (i.e., correlation between residuals). (D) Correlation between the SIC and alpha band’s PSD. (E) Correlation between the residuals for the SIC and alpha PSD following the partial elimination of verbal IQ (i.e., correlation between residuals). Within each diagnostic group and for the whole sample, correlation lines are displayed. For test statistics, see Table 3. The standard error of the mean is displayed as error bars. Significant changes between conditions are indicated by horizontal bars and * (*, p < 0.05; **, p < 0.01; ***, p < 0.001. The p values weren’t adjusted for multiple comparison (Bonferroni)). ASD with DD, Autism disorder spectrum children with development delay group; ASD without DD, Autism disorder spectrum children without development delay group; TD, typical development children group
