Abstract

Objective: The present study was aimed at clarifying the effect of stimulus-response compatibility (SRC) interference on the ERN. Methods: We compared ERNs in two tasks differing in the level of interference, an arrow (AR) task classified as a Simon task and a more complex arrow-orientation (AO) task classified as a spatial-Stroop task. We also compared ERNs between partial errors (with initial incorrect movement corrected by a proper full response) and overt (uncorrected) errors. Results: Behavioral response time and error rate indicated that both interference and ERN amplitude were larger for the AO task than for the AR task. There was no significant difference in the ERN amplitude between the partial and overt errors. Conclusions: The ERN becomes larger as a function of the SRC interference. Significance: Our study presented evidence that the ERN may represent response-monitoring associated with the SRC interference.
