Abstract
As the principal theories of psychosomatic madecine, there are two that should ne mentioned : The Theory of Psychoanalysis by Freud and The Theory of Conditioned Reflex by Pavlov. These two theories, which are often quoted in contrast, have many incompatible elements. Thus, there is the need for developing a third theory which could be commonly acceptable to both of them. Wiener's Cybernetics and Bertalanffy's General System Theory can be considered to comply with this requirement. Although full details on these theories can be not be given here due to space limitations, we will try to explain the theory of psychomatic madicine, with a special emphasis on the rationale for diagnosis of psychodomatic disease, and that for treatment, in the light of the following principles adopted from the Cybernatics the General System Theory : In our daily psychosomatic medicine clinics, we have adopted the following four principles from Wiener's Cybernetics and Bertalanffy's General System Theory. 1. The black box principle 2. The feedback principle 3. The open and closed system principle 4. The information and energy principle Namely, we are using the polygraphic method for the diagnosis of psychosomatic disease, which corresponds to the black box principle. And for control of psychosomatic symptoms, we are using the biofeedback method, which corresponds to the feedback principle. We then use systematic desensitization to relieve the social stressed the psychosomatic disease. This corresponds to the open and closed system principle. Lastly, the Transactional Analysis corresponds to the information and energy principle.
