I was just wondering if it is possible to randomize the location of certain stimuli?
I have a distractor stimuli and a target stimuli that the participant needs to locate, however the location of these stimuli need to be randomized, but they cannot overlap. Is there any way to do this? Or will I have to create a text file, with a large number of pre-made images (with distractors and targets in new locations for every image) that direct RT can randomly draw from so that the subject sees the distractors and target images in different spots throughout their session?
