I’m building an experiment which requires presentation of two images within a routine, side-by-side. One image is a target (i.e. correct response) and the other is a foil. I have an excel stimuli sheet with all the necessary picture files, target stimuli in one column and foil stimuli in another, however I would like the appearance of foil pictures to be fully random. At present, PsychoPy reads out each row such that the same target image is always paired with the same foil. Is there any way around this? Perhaps with the use of a code component?
