A Perceptually Driven Dynamical Model of Rhythmic Limb Movement and Bimanual Coordination

We review the properties of coordinated rhythmic bimanual movements and previous models of those movements. Those models capture the phenomena but they fail to show how the behaviors arise from known components of the perception/ action system and in particular, they do not explicitly represent the known perceptual coupling of the limb movements. We review our own studies on the perception of relative phase and use the results to motivate a new perceptually driven model of bimanual coordination. The new model and its behaviors are described. The model captures both the phenomena of bimanual coordination found in motor studies and the pattern of judgments of mean relative phase and of phase variability found in perception
