Two Succeeding Stages in Acquisition Process of a Rehearsed Drama: Applying System Dynamics to Human Collaborative Behavior

摘要

The study of system dynamics is mainly treated in physics and engineering. However, our study adopted a system dynamic viewpoint to reveal the collective behavior of human beings based on a creative process of drama. This study examined the structure of utterance timing by conducing recurrence quantification analysis (RQA) and discussing an entire system. At the beginning of the trials, utterance rhythms were constructed; however, they were broken in the actual performances before an audience. Therefore, we assume that there are two stages concerning actor performance sophistication. First, actors try to construct utterance timing as group rhythm. Then, after constructing the group rhythm, actors purposely change their utterance timing based on the group rhythm. Based on these results that revealed system construction, we can derive a dynamical model of interaction with dual structure among autonomous agents composed of people such as a teacher and students.
