Coordination Dynamics

Coordination dynamics is the interdisciplinary study of how components of a system — neurons, muscles, limbs, organisms, or agents — spontaneously organize their behavior into stable, functional patterns. Founded by J.A. Scott Kelso, the field applies the mathematical tools of dynamical systems theory and synergetics to understand how coordination emerges, stabilizes, and transitions between modes.

The paradigm example is the phase transition in bimanual finger movements: when subjects oscillate both index fingers, increasing movement speed causes an abrupt switch from mirror-symmetric to parallel motion. This phase transition is governed by a dynamical law — the Haken-Kelso-Bunz (HKB) model — that describes how coupled oscillators self-organize. The same principles have been extended to social coordination, where two people coordinate their movements, gaze, or speech rhythms, generating interactional patterns that neither individual controls.

Coordination dynamics challenges the assumption that behavior is centrally programmed, emphasizing instead the spontaneous emergence of order in complex, coupled systems.
