[Structural dynamics and psychoanalysis -- plea for a dialogue]

The present paper argues in favour of a dialogue between the structural dynamics and psychodynamics. This dialogue has not really taken place, but it would yield important benefits for both sides. First of all, like any other psychiatric discipline psychoanalysis needs a psychopathology as a basic science in order to find its proper place within the psychiatric field; this basic theory is granted by the structural dynamic approach. Both theories encompass many areas of clinical practice and psychological-psychiatric theory. It is worthwhile to try to translate the main concepts of the one approach into the other's terminology. Thus, specific advantages and specific shortcomings in each theory can be unveiled. Three examples are presented, the concept of the unconscious, representational theories and the concept of desactualisation. As an example of how psychoanalysis could profit from structural dynamics, the integration of neurobiological basis into a psychological concept is mentioned. The structural dynamic psychopathology may likewise profit from psychoanalysis, mainly in terms of its therapeutic application.
