is Carl Hollander. Hollander was the 37th director certified by Moreno in psychodrama. He is known primarily for his creation of the Hollander Psychodrama Curve, which may be utilized as a way to understand how a psychodrama session is structured. Hollander uses the image of a curve to explain the three parts of a psychodrama session: the warm-up, the activity, and the integration. The warm-up exists to put patients into a place of spontaneity and creativity in order to be open in the act of psychodrama. The "activity" is the actual enactment of the psychodrama process. Finally, the "curve" moves to integration. It serves as closure and discussion of the session, and considers how the session can be brought into real life – a sort of debriefing. Although psychodrama is not widely practiced, the work done by practitioners of psychodrama has opened the doors to research possibilities for other psychological concepts such as group therapy and expansion of the work of Sigmund Freud. The growing field of drama therapy utilizes psychodrama as one of its main elements. The methods of psychodrama are also used by group therapy organizations and also find a place in other types of therapy, such as post-divorce counseling for children.
