This sequential analysis tested the relative extent to which several adult utterance types elicited conversational replies from developmentally delayed children. Eight developmentally delayed children in Brown's stages I and II and their primary parents were the subjects. Parent-child pairs were video and audio taped during their interactions with experimenter-provided toys in a lab setting. Transcripts of the interactions were coded for adult topic relatedness and obligation level and for child topic relatedness, length, and intelligibility. The results indicated that child replies of any length were elicited by adult topic continuations more than by any other adult utterance type. If a new topic was initiated, explicit prompts for child talk elicited child replies more than other adult utterance types. Multiword child replies were most likely to be elicited by explicit prompts that continued the child's topic. Child effects on the presence and effectiveness of adult conversational recruiting strategies were also tested.
