ERN, error-related negativity; CRN, correct related negativity; ERNresid, residualized difference score for error-related brain activity. Maternal/paternal acceptance, control, and firmness are scales from the Children’s Report of Parental Behavior Inventory (CRPBI). Concern over mistakes and Personal standards are scales from the Frost Multidimensional Perfectionism Scale (FMPS).
