Hi Becca,
thanks for the quick reply.
I did everything you said, but unfortunately I still have the same problem. My problem is that when the first subject finishes its trial sooner than the second subject and hits the key(‘y’). This key does not record for the second subject, which is still in the previous trial, and practically when the second subject finishes its own trial and he hits ‘n’, the next trial starts for the first subject but not for the second subject! How can I call the answer of the first subject that was given before the end of the second subject trial for the next trial of the second subject ?
This image shows my experiment design, I run two tasks(same task) at the same time and subjects do the their own task(task A, task B).
Thanks,
Fazel
