Workaround is to do it at the <block>-level instead: <block myblock> / trials = [1-4=mytrial] / response = correct </block> <trial mytrial> / stimulusframes = [1=mytext] / validresponse = (anyresponse) / correctresponse = ("Y", "N") / errormessage = true(x,500) </trial> <text mytext> / items = ("Stimulus") </text> <text x> / items = ("X") / color = (red) / position = (50%, 60%) </text>

If you wanted to allow participants to press any key, you would have to define / validresponse = (anyresponse) / correctresponse = ("Y", "N") / response = correct Edited 11 Years Ago by Dave

Group: Forum Members Posts: 45, Visits: 249	Hi everyone, I am creating a task where words are shown and Pps have to indicate whether the word describes them by pressing 'Y' or 'N'. I'm just struggling with the error message. I want a text element to appear if they click any key that isn't a 'Y' or a 'N' to remind them of the task instructions basically. Here is this script at the moment: <trial positive> /stimulustimes = [150=positive; 2500=describes] /inputdevice = keyboard /validresponse = ("Y", "N") /errormessage = true(errortext, 1000) /pretrialpause = 500 </trial> However this script causes the errormessage to appear only when a valid response was made, which is exactly the opposite of what I want it to do. Any hep would be much appreciated! Thanks, Charlottte
