title: Regulation of cognitive activity and early communication development in young autistic, mentally retarded, and young normal children.
abstract: Based on the Piagetian framework, this study examined regulation of cognitive activity and developmental communication profiles and their interrelationship in groups of autistic, mentally retarded, and normal children of comparable overall, verbal, and oculo-manual developmental ages (from 6 to 24 months). Regulation of activity was assessed with both an object permanence test and an original behavior grid, and development of communication skills with the Guidetti-Tourrette scales (French adaptation of the Seibert-Hogan scales). The results showed evidence of certain types of dysregulation of cognitive activity and a general delay in communication ability in autistic children compared to the other two groups. Moreover, although the intensity of some of these disorders decreased in relation to the developmental levels of social interaction and joint attention in normal children, they were related to both high and low levels of development of social interaction only in autistic children. These findings raise the hypothesis of a relationship between a disorder of disengaging from an activity and developmental levels of social interaction noted at two transitory periods of early development (12 and 24 months) only in children with autism. Developmental and neuropsychological interpretations of this particular pattern are proposed.
