摘　　要：韵律特征对语法建构的影响是心理语言学和认知神经科学的重要研究内容。韵律信息不仅可以帮助口语理解,而且文本阅读时也要借助韵律特征。为了揭示韵律加工的时间进程和脑机制,研究者使用事件相关电位(ERP)技术取得了一些重要的研究成果。首先,总结了韵律特征和语法结构相互作用过程中可能出现的六个ERP成分:右前负波(RAN)、早期负波(EN)、失配性负波(MMN)、中止正移波(CPS)、P600和P800。其次,针对目前研究韵律加工的特异性成分的不一致、实验任务不符合正常阅读习惯的缺陷、缺乏系统整合性分析这三个问题与争论进行了讨论。最后提出,只有充分考虑包括测试点、被试完成的任务等因素的影响,才能促进语言脑机制研究的进展。The influence of prosody on syntactic construction is a main research issue in the study of psycholinguistics and cognitive neuroscience.Prosody information can help oral comprehension and text reading also needs the help of prosody traits.Some important research results on the brain mechanism of prosody processing have been obtained by means of event-related potentials（ERP）.The right anterior negativity（RAN）,early negativity（EN）,mismatch negativity（MMN）,closure positive shift（CPS） and later component（P600） and P800 related with the interacting between prosody and syntactic construction have been found.The issues and the debate in the domain were discussed such as the differences of the study of the characteristics of prosody processing,the defect of experiment task＇s not conforming to the normal reading habits and the lack of systematic and integral analysis.At last,the paper put forward that we advance research in brain mechanism of language by taking the factors of testing point and the tested finishing task into full consideration.
