This article is a comment on A. Fuchs and J. A. S. Kelso's (1994) theoretical note on models of interlimb coordination. The generality of the order parameter equation derived by H. Haken, J. A. S. Kelso, and H. Bunz (HKB; 1985) for correlated limb movements is underscored through the correct and nonintuitive predictions it makes about steady state behavior. Local and global dynamical models are contrasted, and experimental situations in which local models are pragmatic alternatives to global models, like the HKB equation, are described. Questions are raised about the basis for interpreting detuning in HKB as a simple frequency difference and about the ability of the system of coupled nonlinear oscillators proposed by A. Fuchs and J. A. S. Kelso (1994) to model fully the experimental findings on the spectrum of relative phase.
本文是对A. 富克斯和J. A. S. 凯尔索（1994年）关于肢体间协调模型的理论注释的评论。H. 哈肯、J. A. S. 凯尔索和H. 布恩茨（HKB；1985年）推导的用于相关肢体运动的序参量方程的通用性，通过其对稳态行为所做出的正确且非直观的预测得到了强调。对比了局部和全局动力学模型，并描述了在哪些实验情形中，局部模型是诸如HKB方程这类全局模型的实用替代方案。文中还对将HKB中的失谐解释为简单频率差的依据，以及A. 富克斯和J. A. S. 凯尔索（1994年）提出的耦合非线性振荡器系统对相对相位谱实验结果进行全面建模的能力提出了质疑。
