Fundamental research for training of perceptual skills (I): Can the motor skill learning really contribute to the improvement of perceptual skills?

这项研究旨在调查运动技能练习是否能提高感知技能。我们做了三个投球实验。在实验1中，受试者用两个月的时间练习用射击工具把球扔进靶子。在实验2和3中，受试者垂直向不同的目标投掷一个球，并坐在椅子上接住它。实验对象在三种不同的模式下完成了这个运动的、部分脑力的任务：实际执行、哑剧和没有摇摆动作的想象。对于经历过棒球的被试来说，运动练习可以提高对球释放时手所受的后力的知觉判断的准确性。哑剧投掷再现了在实际投掷中观察到的运动模式，与想象模式相比，显著降低了球飞行的心理模拟的可变性。我们假设模拟运动执行可以在估计运动动作的后果中发挥重要作用。

The research aimed to investigate whether motor skill practices could improve perceptual skills. We performed three ball-throwing experiments. In Experiment 1, subjects practiced throwing a ball into a target using a shooting tool for two months. In Experiments 2 & 3, subjects threw a ball vertically to different targets and catch it while sitting in a chair. The subjects performed this motor, partially mental, task in three different modes: actual execution, pantomime, and imagination without swing actions. For the subject who experienced baseball the motor practice could improve the accuracy of perceptual judgments regarding back-forces acting on the hand at the ball release. Pantomime throwing reproduced the motor patterns observed during actual throwing and significantly reduced the variability of mental simulation of ball flights compared to the imagination mode. We hypothesized that simulated motor execution can play an important role in estimating a consequence of motor actions.
