摘要

本文研究了在事件相关电位(ERP)实验中,晚期二语学习者如何实时解决填充间隙依赖性(FGD),以及熟练程度和工作记忆(WM)如何调节他们的大脑反应。一群中级到高度熟练的汉语英语学习者听了诸如“河马亲吻的斑马*骆驼鼻子跑得很远”之类的句子,其中名词外短语“骆驼”产生了“填补空白”的效果。结果表明,尽管第二语言的行为反应与母语者相当,并且与熟练程度和WM跨度呈正相关,但大脑对填补的空白的反应在性质上是不同的。重要的是,随着熟练程度的提高或WM能力的提高,L2处理模式并没有变得更像原生语言。具体来说,虽然母语为母语的人表现出典型的句法违规和修复的P600,但L2组产生了前额叶中枢阳性。以前有报道称,类似的ERP反映了基于领域的一般注意和非结构的过程,这表明L2组对FGD在线解决中的间隙定位的结构要求的敏感性降低。我们的发现是根据解释L1-L2处理差异的各种建议进行讨论的,包括浅层结构假说。

L2 processing of filled gaps
This paper investigates how late L2 learners resolve filler-gap dependencies (FGD) in real-time and how proficiency and working memory (WM) modulate their brain responses in an event-related potential (ERP) experiment. A group of intermediate to highly proficient Mandarin Chinese learners of English listened to sentences such as “The zebra that the hippo kissed *the camel on the nose ran far away,” in which the extra noun phrase “the camel” created a ‘filled-gap’ effect. The results show that although L2 behavioral responses are comparable to native speakers and are positively correlated with proficiency and WM span, the brain responses to the filled gap are qualitatively different. Importantly, L2 processing patterns did not become more nativelike with higher proficiency levels or greater WM capacity. Specifically, while the native speakers exhibited a P600 typically observed for syntactic violations and repair, the L2 group produced a prefrontal-central positivity. Similar ERPs have previously been reported to reflect domain-general attentional and non-structural-based processes, suggesting that the L2 group has a reduced sensitivity to structural requirements for gap positing in the online resolution of FGDs. Our findings are discussed in light of various proposals accounting for L1-L2 processing differences, including the Shallow Structure Hypothesis.

期刊介绍: LAB provides an outlet for cutting-edge, contemporary studies on bilingualism. LAB assumes a broad definition of bilingualism, including: adult L2 acquisition, simultaneous child bilingualism, child L2 acquisition, adult heritage speaker competence, L1 attrition in L2/Ln environments, and adult L3/Ln acquisition. LAB solicits high quality articles of original research assuming any cognitive science approach to understanding the mental representation of bilingual language competence and performance, including cognitive linguistics, emergentism/connectionism, generative theories, psycholinguistic and processing accounts, and covering typical and atypical populations.
