Hart, Onno van der, 1941-Friedman, Barbara2005-10-032005-10-031989-030896-2863https://hdl.handle.net/1794/1402p. 003-016A century ago there occurred a peak of interest in dissociation and the dissociative disorders, then labeled hysteria. The most important scientific and clinical investigator of this subject was Pierre Janet (1859-1947), whose early body of work is reviewed here. The evolution of his dissociation theory and its major principles are traced throughout his writings. Janet's introduction of the term "subconscious " and his concept of the existence of consciousness outside of personal awareness are explained. The viability and relevance of dissociation as the underlying phenomenon in a wide range of disorders is presented. It is proposed that, Janet's theory and methodology of psychological analysis and dynamic psychotherapy are cogent and relevant for today's students and practitioners.452444 bytesapplication/pdfen-USArticle
