Beyond the Input Given: The Child's Role in the Acquisition of Language

The child's creative contribution to the language-acquisition process is potentially most apparent in situations where the linguistic input available to the child is degraded, providing the child with ample opportunity to elaborate upon that input. The children described in this paper are deaf, with hearing losses so severe that they cannot naturally acquire spoken language, and their hearing parents have chosen not to expose them to sign language. Despite their lack of usable linguistic input, these children develop gestural communication systems which share many structural properties with early linguistic systems of young children learning from established language models. This paper reviews our findings on the structural properties of the deaf children's gesture 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.
