I'm new to OpenSesame and need some help. I have an experiment where I want to show two stimuli at the same time. One of them is always a positive stimulus and the other one is one of the five negative stimulus. The stimuli appear in a random order and also the sides are randomised. Here is where the problem comes in, I want the positive stimulus appear on the same side maximum 3 times in a row and not more. I am not quite sure how to program it. Can someone help me?
