Triggers discriminating errors or correct responses
By using Open Sesame, I am implementing my EEG experiment with participants seeing faces and trying to discrimante the emotional expressions displayed. Before and after my response prompt is displayed in the experiment, triggers with a predefined value (i.e., 27 or 28) have been set. I would really like that the triggers could disentangle whether participants give the correct response or not, by presenting a different value accordingly. In such a way, I can easily remove all the epochs in which the participants gave the wrong responses from my analyses.
In this regard, I would really appreciate your help.
