[Identity and aging: psychosocial approaches].

This review is devoted to the notion of identity with regard to the process of aging from various approaches in social sciences. Continuity or transformation of identity is challenged in advanced age according to the place reserved in the society for the elderly subjects and their social age groups. Study methods are discussed in relation with the theoretical models, and their relevance to address aging people singularity and influence of environment. Changes of identity among elderly subjects appear to proceed in two ways. In the first one, called "rebirth", they establish a new self. In the second way, termed "turning point", better strategy for coping the aging effects is obtained by revealing untapped dimensions of the Self.
