I would highly recommend reading "Human Givens" by Joe Griffin & Ivan Tyrrell. It is an excellent way to gain an understanding about why psychosis happens and given an introduction to the human givens based therapy which is claimed to be effective.
In the de Bono Super Mind Pack he has a cooperation game in which players build hexagons from smaller triangle pieces. They can exchange pieces as well as get pieces from the central heap. It is possible to win by building the most hexagons, but if the ratio of used & free pieces is low then everyone loses. This has been called a zero-sum game.
