Is Conversation Built for Two? The Partitioning of Social Interaction

ABSTRACT Conversation is flexible enough to be conducted with varying numbers of individuals, but most conversation is dyadic. Is the prevalence of dyadic focal participation frameworks facilitated by structures of conversation? Using video recordings of spontaneous naturally occurring conversations, I explore multiperson interactions focusing on how structures of turn taking, sequence organization, storytelling, and speaker gaze facilitate or inhibit the inclusion of multiple individuals in conversation. As I show, because our system favors dyadic participation through turn allocation and sequence organization, sustaining focal triadic or multiparty participation frameworks requires more interactional work than sustaining a dyadic focal participation framework. However, serially dyadic participation, which keeps dyads shifting, and story- and joke telling facilitate the participation of multiple individuals. Although conversational structures can be adapted to partition focal participation as dyadic or multiparty on a moment-by-moment basis, the structures generally facilitate dyadic focal participation.
