Today, social changes question individual and collective identities, or the sense we have of our selves and our relation to others. Based on a crossed methodology, this thesis thinks the problem of identity construction depending on the social link, by comparing the drawings of children from Quebec and Ivory Cost (four drawings projective method: free drawing, human figure, family and ideal family). Eight cases studies, and a statistical comparison with international data (France, Russia, Vietnam), bring to light cultural differences. Priority of self-representation,specific to Quebec, and the subject’s absence in the drawing, particular to Ivory Cost, are studied more precisely. Since drawings testify of identifications at the subjective and social junction, the results synthesis reveals the possibility of a relation between the modern solipsist subject and identification to Same figures, or similar figures, involving regressive aspects. Identification (secondary identification) to Other figures, necessary for the construction of ideals and for an identity that can be projected in the future, seems facilitated in a social link where a symbolic tradition works. In general, we can think identity as an equilibrium between sameness and otherness,witch is influenced by the social link.
