Hi there,
I am currently trying to design a free-choice cognitive dissonance task and am having some trouble figuring out how to best design it. In the first task, participants rate a series of images one at a time on a 1-7 desirability scale. In the second task they are asked to choose between two similarly rated images (two 5's, a 4 and a 5, etc). Is it possible to present participants with a pair of stimuli a second time that are dependent on their original ratings using Direct RT and Medialab? I should also mention this is an EEG study so I would still need to send TTL codes simultaneously.
Thanks,
Eric
