The proposed research program addresses fundamental scientific questions about the integration and development of auditory-motor systems in infancy and into early childhood. Listening to musical rhythms activates motor areas in the brain, and rhythmic movements enhance auditory rhythm perception. These reciprocal neural systems make auditory-motor integration an essential process for the perception and production of music and language. Despite the importance of these neural connections for communication, little is known about how and when these systems become intertwined. The research program will 1) enhance our understanding of how auditory features of rhythms (e.g. pitch, tempo) facilitate rhythm perception and auditory-motor integration in infants and children; 2) investigate how movement facilitates infant rhythm perception; 3) track how rhythm perception and production in early childhood scaffold later vocal fluency. The program will be the first to combine physiological (i.e., electroencephalography or EEG) and behavioural (i.e. video coding, rhythm production tasks) measures to investigate how maturation in auditory and motor brain networks facilitates predictive rhythmic movements. The proposed research will allow students to receive training at the forefront of developmental research. It will also provide students with hands-on learning in neurophysiological, behavioural, and computational techniques. Importantly, this investigation of novel questions about basic sensory-motor abilities and their generalized effects on attention and cognition across the lifespan will make substantial theoretical and empirical contributions to rhythm perception.

拟议的研究计划解决了有关婴幼儿和儿童早期听觉-运动系统的整合和发展的基本科学问题。听音乐节奏会激活大脑中的运动区，而有节奏的动作会增强听觉的节奏感知。这些相互作用的神经系统使听觉-运动整合成为感知和产生音乐和语言的基本过程。尽管这些神经连接对交流很重要，但人们对这些系统如何以及何时相互交织知之甚少。该研究计划将1)加深我们对节奏的听觉特征(如音调、节奏)如何促进婴儿和儿童的节奏感知和听觉-运动整合的理解；2)研究运动如何促进婴儿的节奏感知；3)跟踪幼儿早期的节奏感知和产生如何为以后的声音流畅奠定基础。该计划将首次将生理(即脑电)和行为(即视频编码、节奏产生任务)措施结合起来，以研究听觉和运动大脑网络的成熟如何促进可预测的有节奏的运动。拟议的研究将使学生能够在发展研究的前沿接受培训。它还将为学生提供神经生理学、行为和计算技术方面的实践学习。重要的是，这项关于基本感觉-运动能力的新问题及其对注意和认知的普遍影响的研究将对节奏知觉做出实质性的理论和经验贡献。
