These studies focus on the interplay of sensory and motor function in the control of movement and its perception. The long-term goal is to understand how sensory information is integrated in the control of movement and how sensory function on its own contributes to motor learning. The present studies deal in particular with the idea that sensory perception is modified by learning. The studies extend from an assessment of the degree to which somatosensory input related to speech production affects a speaker's sound classification and, more generally, whether speech motor learning warps a speaker's auditory map. Parallel studies of studies of arm movement address the idea that motor learning results in changes to somatosensory function. The studies are linked by a common interest in the sensory basis of motor learning and control and also a common methodology, the use of servo-controlled robotic manipulators to deliver precise mechanical perturbations to the arms or the jaw.

这些研究集中在运动和知觉控制中感觉和运动功能的相互作用。长期目标是了解如何将感觉信息整合到运动控制中，以及感觉功能本身如何促进运动学习。目前的研究特别关注的是感官知觉是通过学习来改变的。这些研究从评估与语音产生相关的体感输入在多大程度上影响说话人的声音分类，以及更一般地说，语言运动学习是否扭曲了说话人的听觉地图。对手臂运动的平行研究表明，运动学习导致体感功能的改变。这些研究与运动学习和控制的感官基础的共同兴趣以及共同的方法联系在一起，使用伺服控制的机器人操纵器向手臂或下巴提供精确的机械扰动。
