I'm attempting to create a task where the subject is given a pair of pictures and then must respond with the correct answer that is paired to that pair of pictures. For example, if shown A and B, the answer is 1. If shown A and C, the answer is 2. I've setup the pairings in Stim 1 and Stim 2 attributes and the answer tokens in its own attribute (see picture below).
The portion I am stuck on, is I want to provide the correct answer (answer token), and then a random incorrect answer from all possible attribute tokens (attribute1). However, I'm not sure how to reference the all possible answer token responses in the attribute1 field, and further, if it does choose from this list, to not have it potentially select the correct answer token. I'd also like the side for correct answer and incorrect answer to change randomly (see slide below).
