Abstract
Processes of motor control and learning in sports as well as in motor rehabilitation are based on perceptual functions and emergent motor representations. Here a new method of movement sonification is described which is designed to tune in more comprehensively the auditory system into motor perception to enhance motor learning. Usually silent features of the cyclic movement pattern indoor rowing are sonified in real time to make them additionally available to the auditory system when executing the movement. Via real time sonification movement perception can be enhanced in terms of temporal precision and multi-channel integration. But beside the contribution of a single perceptual channel to motor perception and motor representation also mechanisms of multisensory integration can be addressed, if movement sonification is configured adequately: Multimodal motor representations consisting of at least visual, auditory and proprioceptive components - can be shaped subtly resulting in more precise motor control and enhanced motor learning.
Highlights
Visual feedback as well as visual instruction both have a long tradition in the field of motor learning in sports
It is helpful for a novice observing a video of a "model athlete" performing the movement pattern again and again to support motor learning: With the mirror neuron system neuroscientific research has revealed a visual key mechanism participating in motor learning [1]
A first preliminary data analysis revealed differences for the audiovisual condition (AVsoni) sample in terms of faster and more precise learning compared to both other samples
Summary
Visual feedback as well as visual instruction both have a long tradition in the field of motor learning in sports. Video technology has been used on many different kinds of sports like figure skating, apparatus gymnastics or high diving It is helpful for a novice observing a video of a "model athlete" performing the movement pattern again and again to support motor learning: With the mirror neuron system neuroscientific research has revealed a visual key mechanism participating in motor learning [1]. Resulting movement sounds contain structural analogies to visual and proprioceptive percepts enhancing audiovisual and audio-proprioceptive integration [7] and enabling the tuning of the multimodal percept [8] This kind of movement sonification has been used here in a well controlled experiment on motor learning with novices demonstrating that motor learning is enhanced significantly by means of real time movement sonification compared to a visual learning group and to an audiovisual group with natural movement attended sounds
