The aim of this study was to determine: (a) whether children with visual and additional impairments show any non-verbal behaviors, and if so what were the common behaviors; (b) whether two rehabilitation professionals interpreted the non-verbal behaviors similarly; and (c) whether a speech pathologist and a rehabilitation professional interpreted the behaviors similarly. Twelve children, aged from two to eight years, with visual and additional impairments, were videotaped during their play sessions to observe their non-verbal behavior. A rehabilitation professional observed the tapes and identified and interpreted 131 non-verbal behaviors. The study found that the children showed 33 common behaviors. There was 98.4 per cent agreement between the two rehabilitation professionals, and there was 88.5 per cent agreement between the first rehabilitation professional and the speech therapist. The authors go on to suggest strategies for developing the non-verbal behaviors of children with visual and additional impairments. (Contains 4 tables.)
