本文采用事件相关电位(ERP)技术探索汉英双语语义表征的关系。以不同二语(英语)熟练程度的中国大学生作为受试,考察了三种不同句型结构的英文句子及其对应中文句在语义一致和不一致情况下N400的潜伏期和波幅。结果显示,在特殊疑问句条件下,普通受试(只通过CET-4、未通过CET-6,均为本科生)对英文句子和对应中文句子的N400效应差异显著;而专业受试(通过TEM-8,均为硕士研究生)的N400效应差异不显著。这表明两种语言语义表征之间的关系主要取决于二语的熟练程度。同时,二语熟练程度较低受试的语义表征还受到句法复杂性因素的影响。

is study approaches the relationship between Chinese and English semantic representations by means of ERP (Event-Related Potentials) technology with Chinese college students at different English (L2) levels as subjects. Comparisons are made for amplitudes and latencies of N400 elicited by semantically congruous and incongruous sentences, in conditions of three different complicated kinds of English sentence patterns and their Chinese counterparts, with the factor of working memory ability taken into consideration. The results show that for the CET-4 group there are significant differences between the English "Wh" special questions and their Chinese counterparts' N400 effects, whereas no difference is found with regard to the other two sentence types; and for the TEM8 group no difference is found in any of the three sentence patterns. This suggests that the relationship between two languages' semantic representations depends on the students' proficiency of the second language, and the sentence syntax complexity could also be a factor for lower proficient subjects.
