中文摘要： 本项目全面总结与分析了当前学界关于聋人语音编码的研究，提出新的研究思路，运用行为研究与认知神经科学研究的方法，进一步深入探讨聋人语音编码的性质与特点。研究分为四步：第一步，首先探讨聋人汉语加工中语音编码是构音编码的性质问题，并同时考虑其它因素（如，词频、同音家族范畴大小、半球偏侧化）对它的影响；第二步，探讨构音编码的动态形成过程及其激活时程，并考虑其语言学特点；第三步，探讨构音编码与手语加工中的"语音成分"是否与听觉语音编码一样存在知觉范畴性效应；第四步，从聋人作为特殊双语者的角度，探讨聋人手语对汉语构音编码加工的跨语言影响。本项目的研究将进一步丰富对"聋人语音编码"问题的考察，将目前验证性研究推向新阶段，具有重要的理论价值。同时，对探索适合中国聋童的教育模式，为语言障碍儿童提供合理语言康复训练具有十分重要的实践意义。

英文摘要： This project comprehensively summarizes and analyzes the recent studies on phonological coding used by deaf signers in language processing, and it provides a new approach to address the interesting issue. By employing techniques in the behavioral and cognitive neuroscience studies, the project makes a further investigation on the nature and characteristics of deaf signer's phonological coding. The current project comprises four aspects: first and foremost, the main argument is stated that the nature of phonological coding used by deaf signers in Chinese processing should be a kind of articulatory coding, considering such factors as the word frequency, phonological neighborhood, and hemispheric bias. Secondly, a dynamic formation of the articulatory coding and its activation lapse in Chinese processing is examined, with an aim of uncovering its linguistic features. Thirdly, what is investigated in the project is whether the effect of categorical perception occurs in perception of articlulatory coding and "phonological component" of sign language, similar to that of speech coding. Finally, the cross-linguistic effect will be stressed by studying these special bilinguals-deaf signers, in terms of the influence of their sign language on Chinese articulatory coding processing. Via studying the issue of deaf signer's
