Which tasks induce the strongest error-related negativity? I'm trying to build a classifier that measures EEG signals to detect when a subject observes an error being committed by another subject. It seems to me that the strength of the ERN may vary depending on the task, so I would like to create an experiment that evokes a signal that is as strong as possible. Has such a comparison between the strengths of the ERN elicited by various tasks been studied?

Edit: Table 1 of this paper seems relevant.

    $\begingroup$ I think this is more of a question for a literature review rather than something you are likely to find a paper on specifically. I'd also suggest that what you may not want is the "strongest" ERN but a task that is easily able to evoke ERNs. $\endgroup$ – Bryan Krause Jun 21 '18 at 20:43
  • $\begingroup$ @BryanKrause What task do you think most easily evokes ERNs? I've tried the Flanker Task and the Stroop Task, for instance. $\endgroup$ – user76284 Jul 11 '18 at 21:11
  • $\begingroup$ I don't have much reason to suggest others. I think most importantly you need an above-chance task with a reasonable number of errors. If you aren't seeing a signal it probably has more to do with your recording configuration than the task. $\endgroup$ – Bryan Krause Jul 11 '18 at 21:47
