Single-trial test for correlations between ERN/Pe amplitude and posterror RT adjustments. A, Correlations between maximum ERN/Pe amplitude and ΔRT (RT on no-stop trial n + 1 minus RT on noncanceled trial n) for a representative session. Neither the correlation between maximum ERN amplitude and ΔRT nor the correlation between maximum Pe amplitude and ΔRT reached significance. B, Distribution of correlation coefficients (ρs) between maximum ERN amplitude and ΔRT across all sessions. C, Distribution of ρs between maximum Pe amplitude and ΔRT across all sessions.
