I tried to make a Serial Reaction Time Task. And I have a RB-620 Response Pad.
My problem is: It does not work with the keys of response pad. If I use normal keyboard keys, it works…
It only works with response pad, if I choose : the correct response is any key…But if I choose : the correct response is button 1 etc., it does not work!
What can be the reason?
I would be very happy, if someone can help me,
