Select a random sequential order out of a number of fixed orders
I have an experiment in which I have the same set of items, but I have defined 12 different sequential orders in which they will appear (these are fixed orders for balancing and priming reasons). I want one random sequence out of these 12 to be assigned to my participants. To illustrate, here are some (downsized) examples:
Order 1: apple, orange, lemon, cherry, raspberry, kiwi
Order 2: orange, lemon, cherry, apple, kiwi, raspberry
Order 3: raspberry, apple, kiwi, orange, lemon, cherry
Then Participant 1 will randomly be assigned Order 3, Participant 2 Order 1, Participant 3 Order 3, Participant 4 Order 2, etc...
How can I realize this with OpenSesame?
