Videotaped samples of interaction were collected from seven deaf mothers and deaf children, 14 hearing mothers and deaf children using oral-only communication, 14 hearing mothers and deaf children using simultaneous (oral + sign language) communication, and 14 hearing mothers and hearing children. Transcripts were coded for dyadic interaction and for functional communication. Deaf children and hearing mothers using oral-only communication spent significantly less time engaged in interaction than did mothers and children in the other three groups. These dyads also had the least numbers of child-initiated bouts and the highest proportion of nonelaborated bouts. Deaf mothers and deaf children were similar to hearing mothers and hearing children; hearing mothers and deaf children using simultaneous communication were intermediate in interactional complexity. The major finding is that which affirms the similarities between the deaf-mother/deaf-child pairs and the hearing-mother/hearing-child pairs. The children in these two groups share an ability to carry on conversations about themselves, their mothers, and nonpresent objects and events.
The basic impoverishment of deafness is not lack of hearing but lack of language. To illustrate this, we have only to compare a 4-year-old hearing child, with a working vocabulary of between 2,000 and 3,000 words, to a child of the same age, profoundly deaf since infancy, who may have only a few words at his command. Even more important than vocabulary level, however, is the child's ability to use his language for expressing ideas, needs, and feelings. By the age of 4 years, the hearing child in all cultures has already grasped the rules of grammar syntax that enable him or her to combine words in meaningful ways.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
