Literature in the area of play was surveyed, summarized, and organized. The historical approach was used for the collection of data for this study. Materials gathered were acquired through the sources provided by library services as well as current authorities in the field of play therapy. As the material was collected, the focus areas or sections began to naturally develop because of the commonality of the articles. The material found was divided into theory, approach, position, and research. The material found on theory and approach was organized into Chapter II. The material found on position and research was organized into Chapter III. Body movements of both child and therapist offer much research possibility. Since most of the child's language is nonverbal, it is critical that persons develop ways of evaluating and identifying his body signals. Research is needed on the potential use of every toy which is included in the playroom. Research is needed on the potential potency and effect of every type limit set within the play therapy process. Research is needed on the effect of the therapist on the process. Research is needed in reference to training models for the development of play therapy skills in professionals, paraprofessionals, and parents.
