High Quality Content by WIKIPEDIA articles! Theme-centered interaction (TCI) is a concept and a method for working in groups. Its aim is social learning and development of the person. Since the nineteen fifties, TCI has been developed in the United States by the psychoanalyst and psychologist Ruth Cohn, by the therapists Norman Liberman, Isaac Zieman and by other representatives of humanistic psychology. Under the deep impression of the Nazi regime from which Cohn had to flee as a Jew, her overall aim was to assist in creating humane environments which make possible personal growth and living learning as a key to improving society. Later, TCI was developed further in Europe and in India. TCI arose from the theoretical background of psychoanalysis, of group therapy and of humanistic psychology; it takes experiences from Gestalt therapy and from group dynamics into account. Ruth Cohn`s original purpose was to "enable a healthy person to remain healthy". Here "health" not only refers to individual well-being, but also to political responsibility in the world.
