This study examined children's conflict interactions in an attempt to provide evidence for the evolutionary continuity of the organization of power relations within primate societies and childhood peer groups. A total of 17 children, ages 3 - 5, were observed daily at their preschool over a three month period. Two one-half hour video samples were taken each day and the naturally occurring conflict in these video records was analyzed to assess dominance relations. The results indicated that the data collected from observations in this study correspond very closely to the linear dominance model which applies to the group behavior of primates. (JMB)
