Intra- and interpersonal interlimb coordination of pendulums swung from the wrist was investigated. For both kinds of coordination, the steady state and breakdown of bimanual rhythmic coordination as indexed by the time series of the relative phase angle phi were studied under the manipulation of coordination mode, frequency of oscillation, and the difference in the eigenfrequencies (preferred tempos) of the individual oscillating limbs. The properties observed for both intra- and interpersonal coordination were those predicted by a dynamical model of rhythmic coordination that considers the coordinated limbs coupled to be nonlinear oscillators. Using a regression method, the coupling strengths of the coupled system were recovered. As predicted by the dynamical model, the strength of the dynamic was generally greater for the in-phase than the anti-phase mode and decreased with increasing frequency. Further, the strength of the interpersonal interlimb coupling was weaker than that of intrapersonal interlimb coupling.
研究了从手腕摆动的钟摆的肢体内部和人际间的肢体协调。对于这两种协调，在协调模式、振荡频率以及各个摆动肢体的本征频率（偏好节奏）差异的操作下，研究了以相对相位角φ的时间序列为指标的双手节律性协调的稳态和崩溃情况。观察到的肢体内部和人际间协调的特性是由一个节律性协调的动力学模型预测的，该模型将耦合的协调肢体视为非线性振荡器。使用回归方法，恢复了耦合系统的耦合强度。正如动力学模型所预测的，同相模式下的动力学强度通常比反相模式下的更大，并且随着频率的增加而降低。此外，人际间肢体耦合的强度比肢体内部耦合的强度弱。
