摘要
伴随着实时研究方法和技术的发展 ,上世纪 80年代中期之后 ,事件相关脑电位 (ERP)作为一种比反应时更精细和敏感的指标在心理学研究领域中得到大量运用。在语言理解领域 ,目前已发现了三种不同的ERP成分 ,分别是反映词汇 -语义加工的N40 0、反映实时句法加工的ELAN/LAN和后期整合的P60 0 ,这三种成分在正常人和失语症病人之间有着不同的表现形态。在未来 。
As the on-line methods and techniques develop, event-related potentials (ERP) measurement, being more accurate and sensitive than reaction time measures, has been largely used in psychological researches since the mid-80's of last century. In the language comprehension study field, Three kinds of ERP components have been found: the N400 reflecting, the lexical and semantic processes, the left anterior negativities (LAN and ELAN) reflecting the immediately syntactic processes and the P600 reflecting the later syntactic integration. Furthermore, these components have different modalities between the normal and the aphasia patients. In the future, the combination of ERP and other techniques will facilitate the understanding of language comprehension.
