Effects of the age structure of the kindergarten on altruistic behavior

It was hypothesized that children in age-heterogeneous kindergartens would be more prone to behave altuistically than would children in age-homogeneous kindergartens. One hundred and nineteen children from both age structures who lived in kibbutzim and cities in Israel were measured on verbal and behavioral altruism. On all of the measures it was found that children who were studying in heterogeneous classes were more altruistic than were children from homogeneous classes. There was no difference between city and Kibbutz children.
