Note: Adjusted values include diagnosis (SZ vs. OP), age, gender, ethnicity, antipsychotic medication status, premorbid IQ, and socioeconomic status as additional predictors. ERN amplitude was converted to a positive number, such that positive regression coefficients indicate a direct association and negative coefficients indicate an inverse association. Post-error slowing is the reaction time difference between correct trials following errors and the average of all correct trials.
