Description: EMG activity over the corrugator supercilii (cEMG), the primary facial muscle involved in negative emotions, is increased during the commission of errors on speeded reaction-time tasks. In the present paper, data from two previously published studies were re-analyzed to investigate the reliability and stability of error-related, correct-related, and difference cEMG across increasing numbers of trials. We found that for a modified go/no-go and a flanker task, error-related cEMG was highly stable and reliable in 14 trials, and correct-related cEMG between 56 and 82 trials, respectively. Given the typical number of trials used in studies of cognitive control, these findings suggest that many investigations of error monitoring are already sufficient to obtain acceptable error- and correct-related cEMG signals. Error-related cEMG activity is relatively easy to measure, and as such, it shows great promise for future research investigating in the cognitive and affective mechanisms of error monitoring.
