在本研究中，作者研究了人体站立姿势协调模式之间的转换。该分析的动机是模式形成的动力学理论，其中协调模式和模式之间的转换是动物-环境系统动力学的自组织特性。在两个实验中，站立的参与者用头部跟踪移动的目标。结果是一致的假设，身体协调的变化遵循典型的非平衡相变，表现出多稳态，分叉，临界波动，滞后，和临界减速。研究结果表明，姿势可能是有组织的动力学原则，有利于存在的一般和共同的原则，在复杂的系统模式的形成和灵活性。
In the present study, the authors examined transitions between postural coordination modes involved in human stance. The analysis was motivated by dynamical theories of pattern formation, in which coordination modes and transitions between modes are emergent, self-organized properties of the dynamics of animal-environment systems. In 2 experiments, standing participants tracked a moving target with the head. Results are consistent with the hypothesis that changes in body coordination follow typical nonequilibrium phase transitions, exhibiting multistability, bifurcation, critical fluctuations, hysteresis, and critical slowing down. The findings suggest that posture may be organized in terms of dynamical principles and favor the existence of general and common principles governing pattern formation and flexibility in complex systems.
