International audience; Appropriate reactions to erroneous actions are es-sential to keeping behavior adaptive. Erring, however, is notan all-or-none process: electromyographic (EMG) recordingsof the responding muscles have revealed that covert incorrectresponse activations (termed “partial errors”) occur on a pro-portion of overtly correct trials. The occurrence of such “par-tial errors” shows that incorrect response activations could becorrected online, before turning into overt errors. In the pres-ent study, we showed that, unlike overt errors, such “partialerrors” are poorly consciously detected by participants, whocould report only one third of their partial errors. Two param-eters of the partial errors were found to predict detection: thesurface of the incorrect EMG burst (larger for detected) andthe correction time (between the incorrect and correct EMGonsets; longer for detected). These two parameters providedindependent information. The correct(ive) responses associat-ed with detected partial errors were larger than the “pure-correct” ones, and this increase was likely a consequence,rather than a cause, of the detection. The respective impactsof the two parameters predicting detection (incorrect surfaceand correction time), along with the underlying physiologicalprocesses subtending partial-error detection, are discussed.
