I have a flicker paradigm set up (sequence of pictures that flash on the screen for 240 ms each). I am trying to it set up so that I have 2 possible response keys, one of which will continue on with the picture sequence and the other that will end the sequence. I've tried using the !meta function, but the pictures won't forward unless I hit one of the response keys. Is there another way to have the picture sequence continue on a set time until a participant hits the 2nd response key? I've looked into min-max functions, and I'd rather not use that. I'm running the drt file through medialab, unless that doesn't make a difference.
