N1 - 38 N2 - We worked out a six by six months reading of typical conventional gestures and their precursors out from home videotapes of 7 autistics boys from 12 to 36 months old before they had been diagnosed as autistic. The films were analysed using a devised gestures analysis scale (ANAGESTE). Results indicated that conventional gestures appeared between 12 and 23 months old and then disappeared between 24 and 36 months. In addition, we pointed out a direct relation between the mental development degree and the total number of symbolic gestures for each child.These results do not fit with the psycholinguistics theories and they show up a relational and symbolic gesturing capacity in autism the disappearance of which would be a pathological sign UR - https://shs.cairn.info/journal-devenir-2002-3-page-265?lang=en ER -
