Absolute and Relative Coordination

本研究将探讨协调模式之间的 当人们从事简单的（例如，双臂齐动 克里思）和复杂（例如，杂耍）有节奏的活动。其 目标是双重的，（1）通过以下方式确定动力学原理： 肢体之间的节奏协调既能稳定， （2）了解这些原则如何影响 人如何控制，感知新的方面，并学习 这些协调。 一些实验将操纵相位 肢体之间的关系，它们运动的频率 以及它们单独移动的频率。 别人 将涉及熟练的杂耍条件下， 变戏法的对象和变戏法的模式的变量。 的 将使用三维运动分析仪收集数据 并运用非线性动力学的理论和方法进行了研究。 这些结果应该为建模提供有用的约束 协调和有助于理解节奏 运动障碍

This research will examine patterns of coordinations between the arms as people engage in simple (e.g., two arms moving at one tempo) and complex (e.g., juggling) rhythmic activities. Its objective is twofold, (1) to identify the dynamical principles by which rhythmic coordinations between the limbs can be both stable and adaptive and (2) to understand how these principles affect how the person controls, perceives new aspects of, and learns these coordinations. Some experiments will manipulate the phase relation between limbs, the frequencies at which they move together, and the frequencies at which they move alone. Others will involve skilled juggling under conditions which manipulate variables of the juggled objects and the juggling pattern. The data will be collected using three-dimensional motion analyzers and addressed using the theory and methods of nonlinear dynamics. The results should provide useful constraints on modeling coordination and contribute to the understanding of rhythmic movement disorders.
