The behavior modification literature dealing with parent-child interaction has focused on training parents to modify their children's behavior. However, there is ample data which demonstrates that in ongoing social interactions between parents and children, children and parents control the behavior of one another. The viewpoint is offered that a reciprocal relationship between parent and child behavior exists and that behavior intervention strategies should recognize this fact. The present paper focuses on the child's role in determining parent behavior. Available data concerning attempts to train children to modify parent behavior are summarized. (Author)
