I am trying to present two different clips to my participants in two separate events, and have the videos randomized each experiment to account for order effects.
I have inserted video clips into my experiment in a stimulus list, and have selected an event to select “A file chosen from…”. When I try to run the experiment to test it, the event presents both the clips instead of just “A file.” How do I get the event to just select one video to view?
In addition, I want to randomize the videos that are being presented between both events. How do I do this? (let me know if I need to make this question more clear).
