手的拦截运动的速度伴随效应及影响因素

对手的拦截运动的理论假设、速度伴随效应及其影响因素进行了总结和分析。指出:(1)“速度伴随效应”的机制可能在于补偿反应延迟、维持必需的注视时间、对即时运动信息的利用或时间-准确性权衡;(2)手的拦截运动指标受目标运动方向、先前任务、练习、目标大小、运动表征和策略以及双眼线索等因素的影响;(3)对拦截运动的进一步研究可在统一理论解释的基础上进行,克服研究方法和范围的局限。

Speed Coupling Effect of Hand Interception and Determinants

Hypotheses about hand interception,speed coupling effect and its influence factors were reviewed and analyzed in the present study.The authors suggest:((1)The) mechanism of speed coupling effect might be explained in terms of compensating for the delay of response,supplying necessary viewing time,utilizing instantaneous information or speed-accuracy tradeoffs;(2)the interception of hands is influenced by motor direction of the target,previous tasks,practice,the target size,motion representation,strategy,and binocular information;(3)further research could be based on a universal theory to overcome the limitations in method and scope.
