hello!
in my current experiment, I am trying to sample two types of stimuli throughout the block. The trial itself is split up into three phases, where I need one type of trial-unique picture (e.g. indoor or outdoor pictures) to appear during the cue and outcome portion of the trial. Right now, I just have "stim1" at cue and "stim2" at outcome, but I want these items to both be an indoor or outdoor picture given a sequence. Previously, in javascript, I had a set sequence where an indoor picture would be sampled if the randomized array was a 1 (versus a 0) at trial. Ideally, I would want indoor and outdoor pictures to be sampled randomly, without allowing the same type of stimulus to appear in more than two trials in a row. Additionally, I want to set a particular type of reward stimulus (highVal or lowVal at outcome) given the type of stimulus picture sampled at trial.
thank you so much in advance!
