Ego of the child under the age of four years (when basic independence is still not founded) experiences separation from the mother as a trauma. We will follow dynamics of this traumatisation, through revew of the cases of three adult patients during psychoanalitical psychotherapy.This study is mainly occupied with correlation between phase (and sub-phase) of ego development and object-relations during the absence of the mother and the echoes of anaclitic depression of that time upon clinical condition in adulthood.
