Moderators of the internal consistency of error‐related negativity scores: A meta‐analysis of internal consistency estimates

To ensure adequate reliability (i.e., internal consistency), it is common in studies using event‐related brain potentials (ERPs) to exclude participants for having too few trials. This practice is particularly relevant for error‐related ERPs, such as error‐related negativity (ERN), where the number of recorded ERN trials is not entirely under the researcher's control. Furthermore, there is a widespread practice of inferring reliability based on...
