I have a question about randomization and stimulus lists.
I know that if I do not present stimuli randomly (that is, if I don’t randomize in the block), I can pair two items from two different stimulus lists, and that pairing will always be the same. If I do randomize in the block, I get a randomization of each stimulus list, but lose the consistent pairings.
What I want to do is always have the same sound and same picture paired, but randomize the order of presentation of the sounds and pictures.
That is, I want to pair (P1,S1), (P2,S2), etc. and then randomize the order of those pairings. Does this make any sense? Can SuperLab handle this or do I need to randomize by hand?
