Abstract: | Ten different studies comparing children with autism and receptive dysphasia are reviewed. Most of the studies aimed to characterize autism as a language disorder. The representativity of the samples are discussed according to heterogeneity of the autistic and dysphatic populations, and sex and social class distributions. Group differences and similarities are listed and discussed according to sample selection and matching procedures, age and sex distribution, social class membership, and the defining criteria of the two illnesses. It is concluded that the studies do not fullfill their aim, and that the project of comparing dysphatic and autistic children seems unfruitful. Group differences which seem unconnected with methodological difficulties, selection procedure, or group defining criteria, were found in parental background, use of gestures, articulation, and reading. |
