This article reports the results of a study of the effects of a training program designed to facilitate moral development in four specific areas: independence of sanctions, immanent justice, rules in games, and understanding punishment. Included were 58 kindergarten and 60 first-grade children of both sexes, divided equally into treatment and control groups. Children in the treatment groups were read stories designed to stimulate discussion concerning the solution to moral issues presented in the stories. All children were individually pre-and posttested with questions following the presentation of stories. The children in the experimental groups, compared with those in the control groups, improved significantly (p < .01) following the brief training program in three of the four areas: immanent justice, rules in games, and understanding punishment.
