I met such error when running the experiment. What should I do to deal with it?
Any responses are appreciated.

Try looking at the keyboard component called resp_prac_final2.

Make sure the field “Allowed Keys” is either empty or something like “left, right, a, b” depending which keys you want to monitor.

Hope this helps.
