Abstract

The purpose of the study was fourfold: (a) to document the hand preferences of nonspeaking individuals with autism as they produced signs and nonsignactions; (b) to find out if sign-language proficiency in such individuals is associated with directionality or consistency of signing hand preference; (c) to explore the link between hand preference for signing and standardised measures of cognitive and motor development; (d) to compare the hand preferences (sign and nonsign actions) of such individuals to sign-learning children with normal cognitive functioning. In this study, the hand preferences of 14 nonspeaking students with autistic disorder were determined from videotape records of their sign production and nonsign actions. In their sign production, four students strongly favoured their right hands, four had a distinct left-hand preference, and six did not significantly favour either hand. There was little evidence linking sign-language proficiency, cognitive maturity, or motor development to strongly lateralised signing or handedness in general in these students. Compared with the hand preferences of the children in the two comparison groups, the autistic students were markedly less lateralised with respect to signing, but not nonsign actions.
