Abstract采用ERP方法,考察了汉语词汇歧义消解中句子语境作用的时间进程及大脑活动。目标词与句子语境存在一致、不一致、无关控制等3种关系。结果显示:(1)一致与不一致条件下N400的平均波幅均显著低于无关控制条件; (2)SOA为200毫秒时产生的N400平均波幅的幅度显著高于SOA为1000毫秒的条件; (3)N400的平均波幅及潜伏期均表现出左半球显著高于右半球的特点。实验结果支持词汇歧义消解的模块化观点,体现了大脑两半球语言功能的不对称性。

NoteWith the ERP technology,an experiment was conducted to investigate the time course of sentence context in meaning activation of homographs in Chinese,the time course of meaning activation,and the function of the two cerebral hemispheres in the process.The results showed that (1)The amplitudes of N400 to targets both in the concordant and discordant condition were significantly lower than in the control-free condition;(2)compared with the long SOA,the amplitudes of N400 were more negative at the short SOA;(3...
