On the other hand, what I call gestural mimicry requires consideration of factors outside such speaker-internal coupling of gesture and speech. Through detailed analysis of a joint narration task and casual conversation in a dyad, I will show that, once perceived and decoded by a partner, the form–meaning relationship of a speaker’s gesture can become part of the common ground of understanding between the participants. In gestural mimicry, communicativity is observed in the way a speaker’s spontaneous gesture shapes the subsequent gestural move of the interlocutor. With a recurrence of gestural features across speakers, image construal through gesture becomes an interactional phenomenon. That is, gesture as well as speech provides an interactional resource for co-constructing talk. %U https://www.jbe-platform.com/content/journals/10.1075/gest.6.1.03kim
