双手协调及其认知因素的作用

Bimanual Coordination and Influences of Cognitive Factors

双手协调包括左右手、上肢间和上下肢间的动作协调,其绩效受双手相对相位、动作频率、同源肌肉和动作姿势等因素的影响,涉及时间/空间和运动-生理等重要的问题。近年来,知觉对双手协调的作用受到越来越多的关注,涌现了视觉因素、"纯心理学"解释和任务概念化对双手协调的促进作用等相关研究。本文在总结双手协调研究的基础上,突出了认知因素的重要性,并提出了今后研究的思路。

Involving twohand movements and intetlimb coordi nation, bimanual movement performance is influ enced by temporal/spatial and motorphysiological constraints, i.e. relative phase, motor frequency, homologous muscles, and posture. In recent years, perceptual influences on bimanual coordination are elaborated from multiple points of view, such as visual clue, ~sychological＇interpretati^n and conceptu al unifying. After reviewing the previous studies, this paper highlights the role of perceptual impact on bimanual coordination and proposes some advice for further research.
