The majority of existing research has focused on a single marker of error-elicited brain activity—the error-related negativity (ERN), an event-related brain potential (ERP) elicited 50–100ms following an erroneous response. The ERN has accumulated growing interest for its use in clinical contexts as a potential biomarker...
