From Psychological- disciplinary Knowledge to a Transdisciplinary One

The article highlights the relation of congruence and complementarity between disciplinary knowledge and the transdisciplinary one. Without being a new discipline, transdisciplinary emerges from disciplinary research, which in turn is clarified by the transdisciplinary knowledge. First mention of transdisciplinary concept was made in 1970 at the international workshop “L’interdisciplinarité - Problemes d’enseignement et de recherch dans les universités” organized by OCDE in Nisa; the concept was mentioned during the talks among Jean Piaget, Erich Jantsch and André Lichnerowicz. Psychology, as a form of disciplinary knowledge, could benefit from the revitalization and enrichment of its field by approaching a transdisciplinary perspective. This would help achieve a subjective objectivity and an objective subjectivity, by constantly questioning and always check understanding.
