Drift correction: using alternative button instead of spacebar?
we are using a custom built response box that has 3 buttons on it. These buttons produce number-keypresses as if it came from a keyboard: "1", "2", and "3". We are using the left and right button as answer buttons and have everything set to use "1"=no and "3"=yes.
However, we'd like to use the middle button that gives a "2" to trigger the successful drift correction in between trials.
I could not find a way to change the button that is the trigger to move on from the drift correction. Is there a way to do this or a workaround for the input "2" to be translated into a spacebar press?
