Hello!
For my study, I am testing whether people have a preference for the Republican or the Democratic political party. I am running political honestly scores across the screen, for both parties. My plan is to have 80 trials for each participant where on 1/2 of trials the democrat candidate is more honest (Demplus) and the other 1/2 the republican candidate is more honest (Repplus). I want these to be fully randomized across trials such that each participant essentially has a different order of trials where Dem is more honest and Rep is more honest.
However, currently, my script doesn't accomplish this as I instead have 40 trails with Republicans scores and then 40 Democratic scores. Is there a way that I can randomize how each trial appears on the screen within a block?
