Autism associates impairments in social relationships and specific competencies linked to restricted interests. These interests usually focus on mathematics, drawings or foreign language learning and are very significant in the autobiographies of persons with autism without intellectual deficiency. It's seem to be a basement of their self-identity. The personal identity relies on both the self representations and the sense of self. This sense of self supports the self continuity through time which links the present feelings, the autobiographical memories and the future personals projects. The personal identity depends on the memory of life events called "autobiographical memory."
