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

本研究旨在探讨运动技能练习是否能提高知觉技能。我们做了三个投球实验。在实验1中，受试者练习使用射击工具向目标投掷球两个月。在实验2和实验3中，被试坐在椅子上向不同的目标垂直扔球并接住。受试者在三种不同的模式下执行这一运动，部分精神，任务：实际执行，哑剧，想象没有摆动动作。对于经历过棒球运动的受试者来说，运动练习可以提高关于在球释放时作用在手上的背力的感知判断的准确性。与想象模式相比，哑剧投掷再现了在实际投掷过程中观察到的运动模式，并显着降低了球飞行的心理模拟的变异性。我们假设，模拟电机执行可以发挥重要作用，估计电机动作的后果。

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.
