Impaired response inhibition in juvenile delinquents with antisocial personality characteristics: A preliminary ERP study in a Go/Nogo task

•We investigated the response inhibition in JDAP.•Both N2nogo and P3nogo showed reduction in JDAP.•JDAP exhibited impaired response inhibition function. The present study explored the time course of response inhibition function in juvenile delinquents with antisocial personality characteristics (JDAP) by recording the event-related potentials in a Go/Nogo task. Compared to healthy participants, JDAP participants showed similar performance to controls for the Go trails, but worse performance for the Nogo trails. Both N2nogo and P3nogo components showed reduction of the amplitudes in JDAP participants, reflecting the early stage of associated with conflict monitoring and the late stage of inhibition processing, respectively. These data suggest that JDAP participants exhibited impaired response inhibition function.
