熟悉性对中文成语理解的影响:事件相关电位研究

The Impact of Familiarity on Chinese Idioms Comprehension:an Event-related Brain Potential Study

中文成语是惯用语的一种重要形式,采用中文四字成语作为实验材料,以事件相关电位为实验手段,通过N400和P600两种成分考察中文成语的认知理解过程。操纵两个因素,即熟悉程度(熟悉与不熟悉)和词语类型(成语、短语),要求被试对词语进行正误判断。结果提示,与四字短语相比,四字成语在大脑的理解加工存在区别。实验结果支持中文成语加工的构造模型。

Chinese idiom is an important form of idiom,this paper used Event-related potential（ERP）to investigate the cognitive process model of four-character Chinese idioms.The present study manipulated familiarity（familiar/unfamiliar）and word type（idiom/phrase）.Subjects were asked to judge whether the final word is right which stochastic presented in the screen.The result showed that there is no significant difference between familiar idioms and familiar phrases in N400 amplitude,but have a significant difference between unfamiliar idioms and unfamiliar phrases;the P600 latency was quicker for familiar idioms than for familiar phrases,but there is no significant difference between unfamiliar idioms and unfamiliar phrases.Therefore,the comprehension of four-character idioms is different from four-character phrases,and configuration model adequate to explain the present findings.
