I have a trial that is made up of 5 events. Each event is a stimulus list from a folder - 4 of the lists have 10 pictures and 1 list has 40 pictures. Therefore, 80 images should be shown in total. We have the block randomized.
When we went to run the experiment, we found that superlab is showing some of the images more than once. On a practice run, it had 200 events (instead of 80).
Please let us know what is happening? We have never had this problem before.
