The estimated marginal means of amplitude variability over trials of HRs for the two diagnostic groups from the univariate tests of variance.

Note. * = p < 0.05. Standard errors of the mean are presented in the error bars. In all the univariate analyses age was included as a covariate, where the two significant group effects on IC 1 and IC 2 where further tested for the influence of IQ, target mean RT, and social anxiety subscores. (*) = the significant difference between the diagnostic groups on IC 2 were dependent on which covariates were included in the univariate tests of variance. It appeared significant when only age was included as a covariate, though this significant effect did not remain when including IQ and target mean RT as additional covariates to age, and thereafter appeared significant when the social anxiety subscores were included as a covariate in addition to age, IQ, and target mean RT.
