We observe the schizophrenia process through specific structural terms - specific models and shapes of the internalisation deficit and consequental structural variability.

We describe the specific influence of the developmental deficit on the schizophrenic process by presenting the case of a 17 year old female patient diagnosed with schizophrenic psychosis hebefrenic form. By observing the patient's life history, we interpreted her psychological development throug early introjective configurations, identification process, the phase of forming realistic images of the self and the outher world and the forming of the Ego identity. The current state is explained throug deficit Ego functions.

The bringing up of the patient in an unstable and disturbing primary family group, with the mother suffering from Sch psychosis and a grandmother addicted to alchocol, caused pathological modifications in the introjective process and forming of a confused Ego identity. Fragility, non-differentiality and polar exclusiveness of mental representations, which is dependant on the characteristics of the primary object relationschipts, form an insecure mental structure which the patient uses to schape her perception of herself and the world, which can be phenomenologically recognised in the direct and inner presentation of the devil and god as clear and utterly scharp opposites.

The schizophrenic process is connected to the developmental deficit which is conditioned by the failure to organize and integrate the inherent structures forming the core of individual self organization. This essentialy directs development toward the schizophrenic process.
