Hello,
I created a loop so that the same 5 questions can be asked over and over again about my stimuli. I have packed my stimuli into a list that the loop iterates through. The list contains 40 pairs of elements (so a total of 80 list elements [[A1,A1′],[A2,A2′],…,[A40,A40′]]).
I want only one list element to be displayed per pair at a time, randomly, but equally distributed overall (the participant should see 20 A and 20 A’). I also want the order of the items to be random.
I’m sure this must be solvable with “triggers” or recording conditions, but can’t figure out how with the documentation.
Ideas:
(i) Is there a way to remember which list items have already been shown, to use this as a condition (on “include in list if…” or “include in random if…”)?
(ii) Is there a way to edit the questionnaire code directly? Then you could shuffle an array with [[0,1],[1,0′],…,[1,A0]]) and use it as condition or similar.
(iii) Is it solvable with quotas?
Th solution should satisfy (a) an equal distribution (50% A/ 50% A’), (b) random selection of item from pair (A/ A’), (c) random ordering of items (1-40) and (d) no duplicates of items.
I would be very grateful for ideas!
