Brief report: Some remarks about the response relatedness of the error negativity.

The error negativity (Ne) is a prominent response-related potential reflecting error processing or response monitoring processes. Despite the huge amount of literature dealing with the Ne, only few studies investigated how close the Ne is related to the kind of response collected by the experimental setup. The present study investigated whether the Ne differs between force locked and force level related (aka button press) data. Indeed, the Ne was more pronounced for force onset compared to level trigger and appeared to be related to the steepness of the raise of force. These results implicate that the parameterization of the Ne has to be treated with caution under certain circumstances and it appears to be advisable to use force onset or the electromyogram to detect response onset if timing or latency is relevant.
