AimsThis research aims to demonstrate that, in psychosis, addressing the Other allows the subject to differentiate him/herself and to resort to perverse defense mechanisms in order to tune the therapy. The work sets out to highlight the way in which the body articulates with psychic movements as a result of the transfer. MethodThis study is based on an analysis of the effects of an application by a psychotic patient for hospital admission in a psychiatric ward. We explore the succession of subjective alterations occurring in the patient's discourse and in his acting out, whether addressed to the clinician in the psychotherapeutic setting or to the institution. ResultsThe request for care allows the patient to differentiate, at the cost of a masochistic defensive position. Subsequently, annihilation anxiety triggers an exhibitionist process which can be considered as providing leverage turning masochism into sadism. The violence of this relationship is to be found in the transfer to the institution, where transgression of this framework “stages” what would otherwise have been experienced as real: the fantasy of the beaten child. DiscussionThe psychic impasse in psychosis can have quite specific coordinates: either the patient relinquishes his phallic position towards the Other and it is then exposed to destructive aggression, or he may risk mortifying incest. The patient can work this out in the transfer by identifying with parental aggressors. Making the patient responsible for this scenario gives him the opportunity to appropriate new therapeutic efforts. ConclusionDrive enables the psychotic subject to deploy skills and know-how. The process of subjectivation is backed up by the complementary actions of transfer to the clinician and transfer to the institution. If the institution lays the way for a dynamic of acting out, this will have a stimulant effect in the transfer and will replace self-destruction by the fantasy production that reinforces the trajectory of desire.
