Engagement of the motor system in the perception and cognition of music

该研究计划旨在促进有关运动参与在音乐感知和认知中的作用的基本知识。这将通过一系列的四个实验来实现，这些实验的特点是越来越复杂的刺激。前三个系列的实验集中在声乐旋律的运动模拟，开始与两个音符的旋律和表现力表现多音符的旋律结束。第四组实验的重点是在完整的记录音乐作品的节奏电机夹带。我希望通过这个研究项目实现两个主要目标。首先，我打算确定当音乐通过单模态（听觉、视觉、触觉）和双模态输入呈现时，运动系统的参与程度。我假设参与的模式将在刺激属性、输入模态和观察者的经验方面得到独特的表达。其次，我打算确定在何种情况下运动系统的参与可能会影响音乐的处理。在这一点上，认知神经科学并没有一个彻底的概念化，当运动参与是辅助性的，当它是知觉和认知过程的工具。我们相信，拟议的工作是非常新颖的，提供了几个机会，有助于知识的感知和认知过程中的运动系统的功能作用，超越音乐。拟议的工作还准备开发关于在专门设计用于参与运动系统的辅助和康复技术中适当使用多模态输入的关键见解。

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.
