JAS Kelso 和 JJ Jeka(参见记录 1992-41720-001)证明,对称性是区分具有相似和不同解剖特性的组件之间的协调的有用概念工具。目前的实验研究了人类的手臂-腿部模式,以测试其协调不对称性是否通过操纵单个肢体的惯性特性而改变。结果表明:(1)与模型预测一致,增加手臂或腿部的重量分别最小化或增强了协调不对称性;(2)随着运动频率的增加,对扰动的响应减慢,但反映了潜在的协调不对称性。观察到的协调效应表明神经相位关系的影响,并强调对称性在理解系统中的协调方面发挥着重要作用,在系统中,控制不能明确地追溯到单个末端效应器或神经生理学基质。(PsycINFO 数据库记录 (c) 2016 APA,保留所有权利)
JAS Kelso and JJ Jeka (see record 1992-41720-001) demonstrated that symmetry is a useful conceptual tool to distinguish the coordination between components with similar vs different anatomical properties. The present experiments studied human arm–leg patterns to test whether their coordinative asymmetry was changed by manipulating the inertial properties of a single limb. The results showed that (1) consistent with model predictions, adding weight to the arm or the leg minimized or enhanced coordinative asymmetry, respectively and (2) the response to a perturbation slowed as movement frequency increased but in a fashion that reflected the underlying coordinative asymmetry. The observed coordinative effects suggest the influence of neural phase relationships and emphasize that symmetry plays an important role in understanding coordination in systems in which control cannot be traced unequivocally to a single end-effector or a neurophysiological substrate.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
