Interactive communication between children: learning how to make language work in dialogue

In this paper we investigate the development of interactive communication skills in 170 children aged seven to thirteen. Using a communication task that allows extended dialogues between pairs of young speakers, we are able to assess both the overall communicative success achieved by any pair; and from an analysis of the dialogues we can identify several interactive strategies that characterize older and more successful communicators. Successful communication involves the active involvement of both participants: asking and answering questions, volunteering information and responding sensitively to contributions from their partners. In contrast to the process of language acquisition, the development of these interactive skills takes place over an extended time period and subjects vary greatly in their ability to communicate effectively. For many analyses differences in the communicative success achieved by subjects differ more within than between age groups. For example, a substantial minority of our oldest subjects communicate no better than children six years younger.
