Effect of age and MPI IQ on the mean spectral slope. (A) Difference in the mean spectral slope between the three groups of participants. Vertical bars denote 0.95 confidence intervals. The p values (planned comparisons, two-sided t test) are given for between group comparisons. (Eyes-open and eyes-closed conditions were pooled.) (B) Age-related changes in the mean spectral slope in the three groups of participants. R’s denote the Spearman correlation coefficients. The group differences between correlation coefficients (TD/ASD<85, TD/ASD>85, ASD>85/ASD<85) are not significant (all p’s > 0.073). (C) The relationship between MPI IQ and mean spectral slope in TD children and ASD children. R’s denote the partial Spearman correlation coefficients, adjusting for age. TD, typically developing children; ASD, autism spectrum disorder; MPI, Mental Processing Index; ASD>85, children with ASD and MPI above 85; and ASD<85, children with ASD and MPI below 85
