F(1, 134) = 14.5, p < 0.001), with the effects accounting for 3.6% and 9.8% of variance, respectively. The amplitudes of the N2a and P3a did not differ between groups. There were no significant gender, or group × gender, effects for effects in either the target or the rare non-target conditions. The group comparisons were repeated with total ASPD symptoms as a covariate and with total MDD (Major Depressive Disorder) as a covariate. A higher ASPD symptom count was associated with reduced P3b amplitude (accounting for 3.1 % of the variance), and this covariate effect accounted for the group difference in P3b amplitude. None of the other variables were affected by either covariate.
