Note. N = 61 except for correlations with ΔPEA, where N = 60. PES: Post-error slowing; ΔPEA: Post-error accuracy minus post-correct accuracy; Flanker RT: RT on incongruent correct trials minus RT on congruent correct trials; Flanker Accuracy: accuracy on congruent trials minus accuracy on incongruent trials; ΔERN: error-related negativity minus correct response negativity; ΔPe: Pe on error minus Pe on correct trials.
