I have two experiments I am programming. Both contain a set of five practice frames prior to the actual presentation. I’ve used expressions to program a random 5 from the same list used in the main presentation. However, I would not like those 5 that were randomly presented in the practice trial to present themselves in the main trial. They do use the same lists and the main presentaion is 25 from the same list using expressions as well. Is this possible?
Thankyou so much for your continued help. It is so appreciated.
