I'm curious if there is a way to make it so that when participants click on where the deck used to be it does not count as a response. As it is now, the image of the deck goes away once the threshold is reached but click in the place where it was results in a selection from that deck.

Group: Administrators Posts: 13K, Visits: 108K	That's because those functions do not exist in Inquisit 3.

Group: Awaiting Activation Posts: 5, Visits: 22	This works perfectly in Inquisit 4. Thank you so much! The only downside is it does not seem to work in Inquisit 3. When I try to run it I get this error message: <trial igt> Expression 'if (values.deckeselected>=60){trial.igt.removestimulusframe(5);}' is invalid. Item not found.

Group: Administrators Posts: 13K, Visits: 108K	> I also tried using the validreponse attribute but I do not know how to set it to allow for some responses to be valid but not others. You cannot do that with the /validresponse attribute. You need to use /isvalidresponse instead to invalidate a given repsonse option if a certain condition is met: <trial igt> ... / validresponse = (deck1, deck2, deck3, deck4) / isvalidresponse = [values.deckEselected<2 && trial.igt.response=="deck1"] / isvalidresponse = [values.deckFselected<2 && trial.igt.response=="deck2"] / isvalidresponse = [values.deckGselected<2 && trial.igt.response=="deck3"] / isvalidresponse = [values.deckHselected<2 && trial.igt.response=="deck4"] ... </trial> > I've tried using the removestimulusframes attribute but it doesn't appear to be working when I set it to remove one of the deck pictures It is working just fine, but since the stimuli in question are set to not be erased <picture deck1> / items = ("deck.jpg") / position = (20%, 50%) / valign = bottom / erase = false / size = (20%, 20%) </picture> they won't magically disappear from the screen. The removal of the respective stimulusframe <trial igt> / stimulusframes = [1=deck1; 2=deck2; 3=deck3; 4=deck4; 5=deck1label; 6=deck2label; 7=deck3label; 8=deck4label; 9=selectinstructions] / ontrialbegin = [if (values.deckEselected>=2){trial.igt.removestimulusframe(1);}] / ontrialbegin = [if (values.deckFselected>=2){trial.igt.removestimulusframe(2);}] / ontrialbegin = [if (values.deckGselected>=2){trial.igt.removestimulusframe(3);}] / ontrialbegin = [if (values.deckHselected>=2){trial.igt.removestimulusframe(4);}] ... </trial> merely means that the next instance of the <trial> will not (re-)draw that frame anymore. The removal of the labels only "works" because they get overwritten by <text gain> and <text loss> at some point. Thus you are able to notice that they are not re-drawn. My personal opinion is that you should ditch the removestimulusframe() approach. Instead create a blank white jpg the size of the other card images and set the deck picture to that blank image when your card selection threshold is met (just like you set a deck to "deckon.jpg" in case of a selection of that deck).
