[Mother, father, child--on the theory of dyadic and triadic relationships]

Starting with the observable persistence of dyadic relationship models in the present understanding of the psychodynamic process from partner relationships (man-woman) to threesome relationships (mother-child-father), the theory is maintained that specific interpersonal psychodynamic defense processes, effecting both genders help constellate this situation. These dynamics are seen in the contents of the psychoanalytic theory of development. The inappropriateness of dyadic ideas of relationships can also be seen in neonatological research results. Finally triadic thought models in psychoanalytic theory will be presented and discussed. An emancipatory understanding of the threesome relation father-child-mother requires the elimination of the unconscious in the social process, in psychoanalytical discourse and in both genders.
