Many thanks for all your help with my tasks!
Is there a way to tell Superlab to randomly pick from a stimulus list, but not to pick the same picture more than once during an experiment run? there is an option like this for
My task repeats the same trial several times, and is built off the backend you showed me for this task: http://community.cedrus.com/showthread.php?t=2045
Instead of letters, each trial is associated with an event that has a unique stimulus list (~20 pictures of a particular kind of animal). Each time the trial is presented, I would like Superlab to show a picture that it has not shown already this experiment run.
Thanks in advance!
