I am trying to create an interleaved task where participants will need to complete the task with stimuli from two categories (A or B), the order for them to complete it is going to be interleaved (e.g.ABABAB or BABABABA). Right now, my experiment setup looks like this.
I am trying to figure out how I can randomly select the stimuli such that a stimulus will be randomly selected from category A, followed by a random stimulus from category B, and repeat the process until all the stimuli were selected. I cannot use blocking because I don’t want the stimulus to appear in blocks, but I am not sure if it can be done.
Thank you in advance for your help
