Relationship between attention allocation and movement delay in a high speed sport

本研究设计了一个任务，要求剑道运动员在进攻和防守之间切换他们的动作，然后探讨了专业知识的影响和成功和失败的原因在切换动作。在任务中，参与者根据实验刺激进行1)进攻- 2)防御- 3)进攻-防御转换和4)防御-进攻转换动作。在任务3上，专家组的得分高于中间组。结果表明，专家不仅能够快速区分复杂的刺激，而且能够在执行一个动作后立即转换动作。

This study designed a task that required kendo players to switch their movements between offense and defense and then explored the effects of expertise and causes of success and failure in switching movements. In the task, the participants executed1) offensive2) defensive3) offensive-to-defensive switchingand 4) defensive-to-offensive switching movements in response to the experimental stimuli.The expert group scored higher than the intermediate group on task 3. The result indicated that experts had the ability not only to discriminate complicated stimuli rapidly but also to switch movements immediately after executing another movement one time.
