Dear Dave,
I'm designing an experiment where participants first see four pairs of individuals, presented sequentially, where for each pair we indicate which individual is socially dominant. Next, we ask participants to recall, for each pair, which individual is dominant. I would like to repeat this sequence (i.e., first presenting all four pairs, next asking participants to recall) until a criterion is reached; specifically, until participants accurately recall who is dominant in all four pairs in a row, twice. Then I would like to move on the an inferential question (as opposed to recall).
I'm new to Inquisit but I think I will need the branching attribute (which I have been reading about in the documentation the Inquisit website provides). Below you can see I made some progress, but now I'm stuck. I'm not sure (a) how to make branching work without obtaining errors, and (b) whether it would be wiser for me to code the inferential question as a new trial or as new block. If possible, I would appreciate your help.
With regards,
Willem

^^^^In this task, you will see four pairs of individuals. For each pair, we indicate which individual is dominant.^^We ask you to memorize, AS BEST YOU CAN, which individual is dominant in each pair.^^Once you have correctly recalled who is dominant in each pair, twice in a row, we ask you who is dominant is a new pair.^^The survey takes about XX MINUTES. If you choose to participate, you will be free to stop at any time (by notifying the experimenter).</page>
