Motor Learning

One of the goals of the research conducted in the lab is to translate compensation to altered feedback to more natural speech settings. This entails making use of principles of motor learning to promote acquisition of new speech motor patterns, and the gradual withdrawal of experimenter-controlled feedback perturbations. While compensation to various forms of altered feedback has proven to be a robust phenomenon, maintenance beyond the perturbation phase and generalization to novel productions has been limited (Rochet-Capellan et al. 2012 J Neurophysiol). Research in locomotor control has demonstrated improved predictive adaptation and dynamic stability through recurring sensory perturbation, however (Bohm et al. 2015 Sports Med), suggesting that a generalization of new sensorimotor patterns may first require a phase of “de-calibration.”
