相对于从儿童时期获得的母语来说,一般认为二语的句法是非自动加工的。本研究利用ERP技术,在无注意条件下对二语句法中的主谓一致违反情况进行研究,发现大脑在加工二语时,产生了反映句法自动加工的脑电成分MMN,这表明即使二语在关键期之后获得,大脑仍然能够对二语的句法进行自动加工。文章从MMN产生的神经生理机制、二语加工与二语句法加工之间的区别两个方面对二语句法的自动加工进行了分析。 Relative to the mother tongue acquired from childhood, it is generally considered that the syntax of the second language is non-automatic. This study uses ERP technology under the condition of not paying attention to the subject-predicate violation in L2 syntax research and found that the brain in the processing of second language, produced a reflective automatic processing of syntax EEG component MMN, which shows that even if the second language Obtained after the critical period, the brain is still able to automate the syntax of second language. The article analyzes the automatic processing of L2 syntax from two aspects of the neurophysiological mechanism of MMN, the difference between L2 processing and L2 syntax processing.
