An evolutionary diagram that takes into account the development of per
sonality and its structuring or restructuring was developed thanks to
a better understanding of autistic disorders from a psychodynamic poin
d of view through long term psychoanalytic treatment of autistic child
ren. This grid is organised around the major stages of the formation o
f the bodily ego which autistic children helped us understand better.
The construction of space and the capacities of cognitive instrumentat
ion are logically within this line of structuring. These major stages
are defined: the first is the <<successful>> autistic state; the secon
d is the stage where the primary skin is recovered (feeling of a circu
lar envelope); the third is the symbiotic phase which includes vertica
l splitting then horizontal splitting of the image of the body; finall
y, the fourth is the phase of individuation/separation into a whole bo
dy. At each stage the following are assessed: state of the image of th
e body, of the gaze, of language, of writing, the autistic symptoms, e
motional-relational manifestations, exploration of space and objects,
recognition in time, the aggressive behaviours, reactivity to pain and
to immune states (somatic and psychosomatic manifestations).
