Across a diverse range of languages, children proceed through similar stages in their production of causal language: their initial verbs lack internal causal structure, followed by a period during which they produce causative overgeneralizations, indicating knowledge of a productive causative rule. We asked in this study whether a child not…

Handshape works differently in nouns versus a class of verbs in American Sign Language (ASL) and thus can serve as a cue to distinguish between these two word classes. Handshapes representing characteristics of the object itself ("object" handshapes) and handshapes representing how the object is handled ("handling" handshapes)…

The gesture systems developed by 10 deaf children, each incapable of acquiring a conventional spoken language naturally and not exposed to a conventional manual language by their hearing parents, were compared and contrasted to both the speech and the gesture systems developed by three hearing children learning English. (Author/BE)

The study examined whether deaf children's gesture systems are structured at the morpheme level of analysis. A 3-year-old deaf child from the authors' previous study was selected and all of his characterizing signs produced during a 2-hour naturalistic play session in his home were videotaped. Each sign was coded in terms of its handshape, motion,…

Reports that four deaf children of hearing parents, who lacked usable conventional linguistic input, developed a gestural communication system that showed some of the structural regularities characteristic of early child language. Suggests that communication with a number of language-like properties can develop in an atypical language-learning…

Spontaneous gestures of a deaf child unexposed to sign language were studied to determine whether regularities existing within gestures were akin to morphological structure. The child's gestures, handshape/motion combinations forming a matrix for communication, suggest that structural regularity at the intraword level is a resilient property of…

This paper reviews research findings on the structural properties of deaf childrens' gestural communication systems and evaluates those properties in the context of data gained from other approaches to the question of the young child's language-making capacity. (over 100 references) (JL)
