A Computational Account of Movement Learningand its Impact on the Speed - Accuracy Tradeo

We present a computational model of movement skill learning. The types of skills addressed are a class of trajectory following movements involving multiple accelerations , decelerations and changes in direction and lasting more than a few seconds. These skills are acquired through observation and improved through practice. We also review the speed-accuracy tradeoo|one of the most robust phenomena in human motor behavior. We present two speed-accuracy tradeoo experiments where the model's performance ts human behavior quite well.
