Clarification of the mechanism of choking under pressure:focus on the closed-open dimension of motor skills.

本研究的目的是探讨运动压力下窒息的机制，重点是运动技能的封闭-开放维度。此外，应对方法进行了调查的基础上的技能特点。结果表明，在封闭和开放的技能压力下的注意力的变化。这些包括有意识的处理和分散注意力。因此，无论运动技能的特征如何，都有必要适当地控制注意的对象。研究还表明，技能和准确性的移动位移下降，开放技能的效率下降。上述结果表明，应对混乱的知觉和认知，以及与情绪反应是必不可少的技能，需要估计和应对环境的变化，因为这种技能需要准确的感知环境信息和适当的执行动作。

The purpose of this study was to investigate the mechanisms of choking under pressure on sports, by focusing on the closed-open dimension of motor skills. Furthermore, coping methods were investigated on the basis of skills characteristics. The results indicated changes in attention under pressure for both closed and open skills. These included conscious processing and distraction. Therefore, it was considered necessary to control the object of attention appropriately, regardless of the characteristics of the motor skills. It was also indicated that the displacement of movements decreased for both skills and accuracy and efficiency declined for open skills. The above results suggest that coping with confused perceptions and cognitions, as well as with emotional responses is essential for skills that need estimating and coping with changes in the environment, because such skills need accurate perception of environmental information and appropriate execution of movements.
