在一个复杂的多组分系统中，特别是在人类SS的手臂和腿中，研究了图案形成和变化的动力学。观察到的新特征包括：肢体在相同和不同方向上运动产生的协调模式的微分稳定性(实验1)；在相对相位缓慢漂移之前的协调模式之间的转变(实验1和2)；从一种四肢模式到另一种模式的分叉或相变(实验2)；除了相对协调的周期之外，自发出现非1：1频率和锁相模式(实验3)。所有观察到的相对相变模式及其动力学(稳定性、失稳性、间歇性)都显示出来自相同的基本非线性动力学结构，其一个重要特征是对称性破坏。(《心理信息数据库记录(C)2016 APA》，版权所有)
The dynamics of pattern formation and change are studied in a complex multicomponent system, specifically the arms and legs of human Ss. Among the novel features observed are differential stability of coordinative modes produced by limbs moving in the same vs different directions (Exp 1); transitions between coordinative modes preceded by a slow drift in relative phase (Exps 1 and 2); bifurcations or phase transitions from one 4-limb pattern to another (Exp 2); and spontaneous emergence of non-1: 1-frequency-and phase-locked patterns, in addition to periods of relative coordination (Exp 3). All observed relative phasing patterns and their dynamics (stability, loss of stability, intermittency) are shown to arise from the same underlying nonlinear dynamical structure, an important feature of which is broken symmetry.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
