Zusammenfassung:
The Error-Related Negativity (ERN) is a component of the event-related brain potential (ERP)
that is associated with action monitoring and error detection. The present study addressed
the question whether or not an ERN occurs after verbal error detection, e.g., during phoneme
monitoring.We obtained an ERN following verbal errors which showed a typical decrease in
amplitude under severe time pressure. This result demonstrates that the functioning of the
verbal self-monitoring system is comparable to other performance monitoring, such as
action monitoring. Furthermore, we found that participants made more errors in phoneme
monitoring under time pressure than in a control condition. This may suggest that time
pressure decreases the amount of resources available to a capacity-limited self-monitor
thereby leading to more errors.
