| summary | After having briefly presented the coordination dynamics framework, I will present an intriguing setup for studying interpersonal coordination dynamics: boxing. Since the boxers do their best to simultaneously reach and avoid each other, this very complex system may departs from usual experimental paradigm studied in the lab. For practical reasons, we focused on the gross interactions between boxers, measuring head's motion in the horizontal plane. Despite the seemingly erratic motion of each individual, which resembled a random walk, the analysis of head motion showed an ordering of the interactions. A symbolic coding scheme was used to capture the main configurations of the interaction and revealed preferred modes and preferred transitions between these modes. The system studied proved highly degenerate, that is, a particular configuration of interaction between the boxers, or changes between configurations, could be realized by various combinations of individual actions. This situation will offer a playground to open a discussion on the role symmetry plays in general in coordination dynamics. A basic toy model is proposed, inspired by the essential features of the experimental data. |
