This study examined the effects of adult “recasting” in sign language on the acquisition of specific syntactic-semantic structures by six deaf children between 9 and 76 months who were primarily at the one-sign utterance stage of development. In “recast” replies in conversation, the child's utterance is redisplayed in an altered sentence structure that still refers to the central meanings of the first sentence. Syntactic-semantic structures targeted for input intervention by teachers and parents using recasts included subject–verb relations, attribution, negation, subject–verb–object relations, conjunction, and conditionality. Recasting triggered the acquisition of new syntactic-semantic structures in American Sign Language and English which were evident in the spontaneous production of previously non-used sign utterances.
