摘要: 操纵不同违例类型(语义单违例、句法单违例、双违例)及不同的违例词位置(句中、句尾),运用ERPs技术初步探讨了中国大学生二语(英语)学习者英语简单句的心理加工过程。结果发现,中间句法单违例诱发了早期左前负波(ELAN),句尾句法单违例引发了正波(P600)。句尾语义单违例诱发的负波(N400)波幅显著大于中间语义单违例。即存在违例关键词的位置效应。较之单违例,语义-句法双违例诱发的N400P600波幅变化呈非对称性。语义-句法双违例句诱发的P600波幅大于句法单违例句;语义-句法双违例引发的N400波幅均小于语义单违例句。这说明句法与语义加工之间存在交互作用,句法加工在很大程度上受到语义加工的影响,句法加工对语义加工的影响较小。

Randomly selecting 20 university students (10 female, 10 male) as subjects, who were right-handed and had passed CET-4 and Manipulating different anomaly types (semantically, syntactically or doubly anomalous sentences) and anomaly words at sentence-internal and sentence-final position, the study probed into Chinese ESL learners’ mental mechanisms of English active sentence processing by using ERPs. Specifically, the experimental materials included 360 active sentences whose length ranges from 6 to 8 words and were classified into six types (each type includes 60 sentences): control sentences, sentence-internal syntactic anomalies, sentence-internal semantic anomalies, sentence-final syntactic anomalies, sentence-final semantic anomalies and sentence-internal and sentence-final double anomalies involving both semantic and syntactic difficulties. The task of subjects was to judge whether the sentences were correct. In addition, the indices of the observation were reaction times, the rate of correct responses and ERP indices in the process of the experiments.
The results indicated: Under sentence-internal syntactic anomalous condition, the ELAN was visible. Under sentence-final syntactic anomalous condition, the P600 was observed. In relation to semantic anomalies, the sentence-final N400 was significantly larger than the sentence-internal. There existed the effect of word position. Under doubly anomalous condition, both the N400 and P600 were detected and the change on amplitude showed an asymmetry compared to single anomalies. To be specific, as for the P600, double anomalies elicited a larger increase in the P600 amplitude. With regard to the N400, double anomalies produced smaller amplitude. The pattern of results showed the interaction between semantic and syntactic processing. Semantic processing had greater impact on syntactic processing.
