| Research Abstract |
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.
