Psychoanalysis is a life-long study and a personal experience: Peter Kutter received a first psychotherapeutic training in Stuttgart at the Institute of Psychotherapy. Later he obtained a second qualification in psychoanalysis at the Sigmund-Freud-Institute in Frankfurt am Main; with Wolfgang Loch as training analyst, Clemens de Boor and Margarete Mitscherlich as supervisors.
Four phases of professional development can be differentiated:
- a rather psychotherapeutic approach (Stuttgart),
- a rather theoretical approach (Tübingen),
- the so-called "scenic understanding" (Sigmund-Freud-Institut), and finally
- the psychoanalytic self-psychology.
Kutter was at first stimulated by the so-called synoptic approach at the Stuttgart institute: Hermann Gundert, Bertha Sommer, Jutta von Graevenitz.
Major personal models on an international level were Jeanne Lampl-de Groot and Piet Kuiper, with whom he was also in supervision, and later Joseph Sandler, Horacio Etchegoyen, Otto F. Kernberg and Joe D. Lichtenberg, Anna and Paul Ornstein as well as Ernest S. Wolf.
Kutter is a member of the DGPT (since 1965), of the German and International Psychoanaltical Association (since 1968). He belongs to the "Frankfurt Psychoanalytical Institute".
