Hello,

I am trying to create an experiment consisting of two images side-by-side on the screen, with the hposition of the images randomized for all trials (20% or 80%), and participants will press either the right or left arrow to select the correct image. There are a total of 18 trials randomized in order, and we want to program it so that the correct response is never on the same side for more than three trials in a row (e.g. the correct answer will never be on the left for more than three trials in a row). We also want there to be an even number of left and right correct answers. Is it possible to do this?

Thanks in advance!
Dave

Yes, all of that is perfectly possible to do.
