In this study, it was shown that shared communication systems can be formed from scratch through interactions by designing a language evolution experiment utilizing a coordination game with symbolic message exchange. We show that three scaffolding stages exist in the process of formation of symbolic communication systems in which connotations are communicated as well as denotations. The three stages are building common ground, sharing a symbol system, and forming a role division. At the third stage, communicating connotations is realized by arranging an appropriate turn-taking. Analysis using simulated experiment with ACT-R, a cognitive architecture for simulating and understanding human cognition, suggests that role-reversal imitation is important for achieving shared communication systems.
