This work proposes to make a raising of studies that conceive the autism as a disturbance of affective contact. To become it possible, the developmental perspective will be used because it conceives that every psychological development is the result of a social construction and not just a determinist biological maturation. The affective engagement is what makes possible the development of the child s social interaction. When failures occur in the affective relation between mother and baby, shortages can occur in the primary and secondary intersubjectivities. Damages in the communication and in the speech occur, as consequence. By the study of the typical development, we ll see what didn t occur in the autism. To illustrate the research, autobiographical narratives of people with autistic spectrum will be presented. These fragments help in the comprehension of how autistics live the affective matter.
