12. Starting Position:	Put your hand in front of you about shoulder height as if you are about to push open a swinging door. Your fingers should be pointing upwards.
Action:	Extend your arm fully as if you are pushing open the door, keeping your fingers pointing upwards. Now let the swinging door close by returning your hand and arm to the starting position.
Mental task:	Assume the starting position. Attempt to feel yourself making the movement just performed without actually doing it. Now rate the ease/difficulty with which you were able to do this mental task.
