Clinical variables with no significant correlations to EEG variables are not included. All correlations are Spearman’s rho. All correlations represent the FXS group only. Due to the negative amplitude of the N1 ERP, negative correlations should be viewed as increased N1 amplitude correlating with increased scores on the clinical/behavioral measure. Blank = N.S. ^∗p < 0.05, ^∗∗p < 0.01.
