The Influence of Second Language Proficiency on Sentence Comprehension: An fMRI Study

在本研究中，我们进行了一个实验，以揭示句子加工的机制，在分析混乱的句子在韩语作为第一和第二。结果表明，在理解乱句时，左额下回和左额中回的激活程度高于规范句。这表明，与先前从神经语言学角度对打乱的研究结果一致，韩语中的打乱确实是一种语法操作，并且对不对称先行词-间隙关系的分析策略需要大脑额外的认知激活。

In this study, we conducted an experiment to unravel the mechanism of sentence processing during the parsing of scrambled sentences in Korean as L1 and L2. The result showed more activation at the left inferior frontal gyrus (IFG) and the left middle frontal gyrus (MFG) during the comprehension of scrambled sentences than that of canonical sentences. This indicates, in accordance with previous findings on scrambling from neurolinguistic perspectives, that scrambling in Korean is indeed a grammatical operation and that the parsing strategy for the asymmetric antecedent-gap relationship demands an additional cognitive activation in the brain.
