Title: Constructing the Theory of Motor Learning Curves─Dynamical System Approach The process of learning two multi segments motor skills were examined as the basis to construct the theory of learning curve in dynamical system perspective. Four adults participated in experiment one learn the pedalor task for 350 trails in 7 individual days. An opto-electronic tracking system was used to record movement trajectories. The variability of movement velocity, movement time and different between two successive trials in space were derived as the temporal and spatial variables to assess the performance. The Cauchy theorem was applied as the criterion to quantify the learning process, and the exponential and power function were test for describing the learning behavior. Four junior high school students participated in experiment two to learning the virtual ball hitting task of 60 trials or 30 minutes a day for 12 individual days. A virtual reality simulation system was used to create the visual information for learning a forehand hit task. A movement image digitize system was used to capture the displacement in 2 dimension space and the differences of two successive trials were derived for analysis. The results of two experiments in this study showed that the exponential function is best for describing the multi segment motor tasks in this study. The study also provided an useful measure device for investigating the high dimensional system of motor learning. These findings provide the empirical evaluation for dynamical system theory for motor learning curve, and also extend our current knowledge on the process of multiple segments motor coordination.
