Reliability of the ERN across multiple tasks as a function of increasing errors

Event‐related potential ( ERP ) studies of error‐processing have characterized the error‐related negativity ( ERN ) as a negative deflection occurring after the commission of an error at frontocentral sites. The ERN has frequently been examined in the context of individual differences and has been proposed as a neurobehavioral risk marker. Given this, it is important to characterize the psychometric properties of the ERN across multiple tasks as...
