This film is a demonstration of how social situations pattern behavior in rats. The film shows a competitive food-obtaining situation in which rats develop sharing or altruistic behavior. It also shows a situation in which competitive behavior becomes increasingly severe instead of developing into sharing. Displaced aggression, hoarding, and other socially significant behavior are shown.
