Note. Descriptive statistics and results from logistic regressions predicting the log odds probability of an error response per one standard deviation positive change in voltages of standard ERP (top) or overlap-corrected regression ERP measures (rERP, bottom). Negative-valued BERROR and ORs smaller than 1 reflect greater odds of an error given lesser positivity (smaller amplitudes) of Frontocentral P3 (mean value within 340 to 440 ms in stimulus-locked waveforms) or PMP (−160 to −60 ms in response-locked waveforms). We used asterisks to highlight uncorrected p-values that survived correction for multiple comparisons at pFDR < .01. Confidence intervals enable comparison of odds ratios at the p < .05 level. Other abbreviations: MLM = multi-level model; SE = standard error; PMP = Pre-Movement Positivity
