I want to present two images simultaneously, and then let them disappear after 3 seconds, or as soon as an answer is given.
After an answer I want to go on to the next trial, regardless when the answer was given. So, if it takes participants more than 3 seconds to give their answer, then the images should disappear and the programme should wait for an answer. If, however, a participant answers after 1 second, I want the images to disappear and the next trial to begin.
I have managed to present 2 stimuli simultaneously, and it works when either I insert a blank “answer” event (as long as participants don’t answer until the images disappeared), or, when I don’t insert an “answer” event, but participants answer before the images disappear.
But the combination of the two seems tricky…
Seems to me like a coomon thing to do, but haven’t managed to create an experiment file that does that…
I am very grateful for any kind of help!
