ABSTRACT
Enrique Pichon Riviere was one of the founders of psychoanalysis in Argentina. His thought unquestionably produced original conceptions of mental illness, therapy, the group, the subject, and creative processes. Pichon Riviere was eighteen years old when he moved to Buenos Aires to study medicine. There, he led a bohemian life, frequented artistic circles, especially painters and writers whose friend he became, and founded with some of them a Surrealist journal. Before leaving Hospicio de las Mercedes, he set up a special ward for adolescents who, hitherto, had been placed with, and treated along with, the adults. In 1950, Pichon Riviere helped to create the Association of Psychology and Group Psychotherapy. In his text “Contributions to the didactics of social psychology”, Pichon Riviere defines conceptual referential and operational schema (CROS) as an organized set of general theoretical notions and concepts referring to a sector of reality, to a universe of discourse, permitting an instrumental approach to the particular concrete object.
