Prolegomena of a theory of between-person coordination of speech and gesture

This paper describes some examples of what is here called between-person coordination of speech and gesture. It attempts to explain the phenomenon in terms of the principles set forth in Growth Point theory (GP theory). McNeill has proposed this to explain what is here contrastively called within-person coordination of speech and gesture. In due course, the advantages of GP theory over the other existing theories of speech-gesture coordination will be discussed, and some implications for interactional graphical communication will be noted
