Group: Forum Members Posts: 27, Visits: 115	hi dave! thanks a lot! erase does the trick. Now I only have the problem, that my pretrialpause is being ignored. The stimuli are displayed the whole time, without pauses between them. Do you have a quick fix for that?

Group: Administrators Posts: 13K, Visits: 104K	As per the documentation, /responseinterrupt=trial means "Any remaining frames in the trial are presented before the stimuli are erased. Any media stimuli (sound or video) are played to completion before Inquisit advances to the next trial." Since your trial only presents a single frame at the very start /stimulusframes = [1=eegvovax] there is nothing /responseinterrupt=trial could have any effect on -- there are no more frames that could or should be displayed. If you want the stimulus "eegvovax" to remain on-screen after receiving a response, set its /erase attribute to false. Also note that a timeout merely determines a trial's maximum duration -- it will terminate immediately once a response has been received. If you want your trial to have a fixed duration, you ought to use /trialduration. Edited 10 Years Ago by Dave

Group: Forum Members Posts: 27, Visits: 115	Hi! I want to present Stimuli, and get the user's response. I also want to show an errormessage, if the answer is wrong. But: I want the duration for the stimuli to be the same, no matter after how many milliseconds the user answers. Here is my code: <trial eegvovax> /stimulusframes = [1=eegvovax] /pretrialpause = values.pretrialeeg /responseinterrupt = trial /response = timeout(1250) /validresponse = (" ") /correctresponse = (" ") /errormessage = (eegerror, 500) </trial> No matter if i set the responseinterrupt value to immediate, trial or frames, the response always cancels the trial. Could you help me please? :) Thanks for the great support so far!
