A STUDY ON CHINESE AND ENGLISH SEMANTIC ACCESS WITH ERP TECHNOLOGY
汉英语义通达过程的事件相关电位研究

This study approached the bilingual representation with ERP (event related potentials) technology. Comparisons were made for ERP amplitudes and latencies of P190 and N400 elicited by the last word of the semantically congruous and incongruous sentences in the conditions of within and between language integration during the 500ms after it was presented. The result suggested that P190 represented the effect of lexical processing which was different between English and Chinese, while N400 represented the effect of semantic processing in which Chinese and English shared the same pattern. The result indicated that bilinguals' two languages are represented separately at lexical level but commonly at semantic level .
