Hi,
there has finally emerged a version worth a little experiment which I made yesterday. It requires two players. The first one starts by raising either left or right, or both hands. The response of the other person consists of giving the right name for the first player’s movement, accompanied simultaneously by own independent choice of any of these three possible movements (and then player one does the same). As an example: the first player raises the right hand, the second one answers saying ‘right’ and raises independently both hands at the same time, then player one says ‘both’ and raises for instance both hands, player two says ‘both’ and raises left hand, player one answers saying ‘left’ and raising something and so on… All the movements are independent, all the names depend on the movement of the partner. Players take care for the irregularity in the succession of movements.
Both poeple I played several steps of the above game with exhibited certain confusion and delay in giving response.
