Temporal development of pragmatics and dynamics in conversation for building consensus

We studied the process of information integration through observing pragmatics and dynamics of conversations toward a consensus between two persons. From the pragmatic perspective, the temporal development of pragmatics regarding their consensus was analyzed with conversational analysis and subjective evaluation. From the dynamical perspective, the temporal development of response time of utterance was analyzed with correlation analysis. As results, their typical developments were clarified. Pragmatic stages regarding consensus were taking turns alternately toward a consensus. The subjective evaluated values on their consensus increased toward the end of the conversation. The temporal variation of response times were synchronized interpersonally toward the end of the conversation. These results show that temporal development of pragmatics and dynamics are mutually related. Furthermore, it is suggested that synchronization dynamics of utterance plays an important role for information integration of consensus building.
