The purpose of this study was to examine the processes and patterns of communicative interaction which preschool and elementary school-aged deaf and hearing siblings utilized to initiate, maintain and terminate dialogs during play. Specifically, the focus was to determine if the processes and patterns of communication differed when a deaf sibling interacted with an older hearing sibling who has been exposed primarily to a simultaneous visual-auditory (SimVA) pattern of communication, as compared to when a deaf sibling interacted with a younger hearing sibling who has been exposed to both a SimVA and a sequential visual (Seq V) pattern of communication. Video-taped playbouts were observed between each of two sibling dyads at play within a single family: (a) an older dyad composed of a seven-year-old hearing child and her five-year-old deaf sister, and (b) a younger dyad with the second-born deaf sister and her three-year-old hearing brother. The video-tapes were coded to determine: the kinds of play siblings engaged in; the use and expression of behavioral and communicative elements of attention-getting, exchange of information, and termination processes of dialogs; who initiated and terminated dialogs; the occurrence of turn-taking during message delivery; and the expression of patterns of communication used by siblings during dialogs. Only three of five possible kinds of play were actually noted, of which social play was the most frequently observed kind of play taking place between siblings within both dyads. In the older hearing and deaf sibling dyad, it was found that the older hearing sister predominately used visual processes and patterns of communicative interaction when conversing with her deaf sister, whereas the deaf sibling relied extensively on visual-auditory processes and patterns of communication when conversing with her hearing sister. In the younger dyad, visual-auditory patterns of communication predominated both hearing and deaf siblings' expression of processes and patterns of communication with each other. New terminology reflecting siblings' behavioral and communicative patterns of communication are introduced. This study represents the first known research examining the processes and patterns of deaf and hearing siblings' behavioral and communicative interactions of dialog. The findings are discussed in relation to potential applications to early intervention programs for hearing families with deaf and hearing siblings and to future research directions. Overall, the findings from this study appear to indicate that deaf and hearing siblings communicate in ways largely influenced by developmental maturation and the communicative environments to which each child has been exposed during language acquisition processes. The findings are also consistent with Vygotsky's theory of a sociocultural origin of language development.
