Error-processing is increasingly examined using the error-related negativity (ERN) and error positivity (Pe) - event-related potentials (ERPs) that demonstrate trait-like properties and excellent reliability. The current study focuses on construct validity by applying a multitrait-multimethod approach, treating error-related ERPs (i.e., ERN, Pe and the difference between error minus correct, referred to as ERN and Delta Pe, respectively) as traits measured across multiple tasks (i.e., Flanker, Stroop, and Go/NoGo). Results suggest convergent validity of these ERPs ranging between .62 and .64 for Delta ERN. Values were somewhat smaller for ERN (range.33-.43), Delta Pe (range.37-.49) and Delta Pe (range.30-.37). Further, the correlations for ERN and Pe are higher within components across tasks than between different components suggesting discriminant validity. In conclusion, the present study revealed evidence for convergent and discriminant validity of error-related ERPs, further supporting the use of these components as psychophysiological trait markers.
