中文摘要： 作为一种古老而普遍的系统，语言和音乐同样是人类社会特有的。语言，尤其是声调语言，与音乐有密切关系。声调语言与音乐之间的双向影响，这方面已经有大量的研究。但是声调与音乐是否共享生理和神经基础，这一重要理论问题还没有很好的解答。本项目拟从先天性失乐症的角度，利用行为实验、事件相关电位、磁共振成像等手段研究广东话声调与音乐发声和感知的机理。失乐症是一种以音高加工为主的障碍，汉语背景的失乐症者可能还有声调和语调障碍。但是，汉语背景失乐症者的发声和感知的机理还不清楚，目前只有少量针对普通话背景失乐症的研究。本项目针对广东话人群，一方面可以验证基于非汉语和普通话背景失乐症的发现，深化对失乐症的普遍性的认识，为失乐症的治疗提供理论支持; 另一方面，广东话声调的复杂性有助考察不同声调系统、尤其是复杂声调系统对声调和音乐加工的影响。研究失乐症者的发声和感知障碍将深化我们对语言与音乐的关系的认识。

英文摘要： As an old and ubiquitous system, both language and music are unique to the human society. Language, especially tone language, has a close relationship with music. The cross-domain transfer between tone language experience and musical training has been well documented. However, the question of whether lexical tone and music share common physiological and neural bases remains largely unsolved. In this project, we aim to use behavioral, event-related potential (ERP), and functional magnetic resonance imaging (fMRI) methods to examine the physiological and neural bases of the production and perception of Cantonese tones and music, from the perspective of congenital amusia. Congenital amusia is a developmental disorder primarily in pitch processing. Chinese-speaking amusic individuals may also have disorders in lexical tone and intonation processing. Despite its importance, the physiological bases of amusia in the Chinese-speaking population remain unclear. So far, there are only a few ERP studies that have examined Mandarin-speaking amusic individuals. This project focuses on the Cantonese-speaking population. On the one hand, it will enable us to verify previous findings based on non-Chinese-speaking and Mandarin-speaking amusic individuals, in order to reveal the universal aspects of amusia, and to provide evidence for intervention for amusic individuals. On the other hand, it will allow us to examine the influence of different tones systems, especially complex ones, on the production and perception lexical tone and music. Examining the physiological and neural bases of production and perception disorder in amusia can shed important light on the relationship of language and music.
