This program of research is intended to contribute to basic knowledge about the role of motor engagement in perception and cognition of music. This will be accomplished through a series of four experiments that feature increasingly complex stimuli. The first three series of experiments focus on motor simulation of vocal melodies, commencing with two-note melodies and ending with expressively performed multi-note melodies. The fourth series of experiments focuses on motor entrainment of rhythm in complete pieces of recorded music. There are two main objectives I hope to achieve with this program of research. First, I intend to determine the extent to which the motor system is engaged when music is presented through unimodal (auditory, visual, tactile) and bimodal input. I assume that the pattern of engagement will be uniquely expressed in regards to stimulus properties, input modality, and an observer's experience. Second, I intend to determine the circumstances under which the engagement of the motor system may impact the processing of music. At this point cognitive neuroscience does not possess a thorough conceptualization of when motor engagement is ancillary and when it is instrumental to perceptual and cognitive processes. We believe that the proposed work is highly novel, providing several opportunities for contributing to knowledge about the functional role of the motor system in perceptual and cognitive processes that transcend music. The proposed work is also poised to develop key insights about the appropriate use of multimodal input in assistive and rehabilitative technologies that are specifically designed to engage the motor system.

该研究计划旨在增进有关运动参与在音乐感知和认知中的作用的基础知识。这将通过一系列四个实验来完成，这些实验的刺激越来越复杂。前三个系列的实验侧重于声乐旋律的运动模拟，以两音符旋律开始，以富有表现力的多音符旋律结束。第四系列实验的重点是完整录制音乐片段中节奏的运动夹带。我希望通过这个研究计划实现两个主要目标。首先，我打算确定当通过单模态（听觉、视觉、触觉）和双模态输入呈现音乐时运动系统的参与程度。我假设参与模式将在刺激属性、输入模式和观察者的体验方面得到独特的表达。其次，我打算确定在什么情况下运动系统的参与可能会影响音乐的处理。目前，认知神经科学对于运动参与何时是辅助的以及何时对感知和认知过程有帮助尚不具有彻底的概念。我们认为，所提出的工作非常新颖，为了解运动系统在超越音乐的感知和认知过程中的功能作用提供了多种机会。拟议的工作还准备开发关于在专门设计用于运动系统的辅助和康复技术中适当使用多模式输入的关键见解。
