Two studies were undertaken to assess distributive justice development in lower-and middle-class children attending social-class-integrated schools.In Study 1, 28 middle-and 28 lower-class white children from kindergarten and third grade were given the Distributive Justice Scale and a vocabulary test. Results showed that regardless of grade, the lower class lagged behind the middle class in distributive justice development even when vocabulary was controlled. In Study 2, 32 middle-and 32 lower-class black children from kindergarten and third grade were given the same measures plus sociometric peer ratings. The results replicated Study 1. The peer ratings showed that lower-class children were chosen most often for negative sociometric questions. Implications are drawn for both distributive justice development and social class integration.
