Using an integrative approach, we address the mechanisms inherent to a child's imitative play with peers. From a psychoanalytic perspective, in a study of the fraternal bond, we see that these exchanges in which the discovery linked to the other and itself originate from the experience of a game, in the name of intimate connection, in the heart of the being, uniting the intrapsychic and the intersubjective. Then, from a cognitive perspective, this intersubjective dynamic will reveal changes in points of view made from successive reversals of position, both self- and heterocentering, testing the visuospatial relations and motor skills of the child. From these descriptions, we propose a developmental model of empathy in thought of the intimate process closely related to the very structure of the subject. A return to clinical child and adolescent medicine will be an opportunity for us to question the place of such mechanisms with the idea that they can offer an original psychopathological approach.
