英语二语口语句子产出中的递增加工

Incrementality in English as second language oral sentence production

本文通过两个句子补全任务考察不同水平中国英语学习者口语句子产出中的递增加工机制。实验发现,中国英语学习者的递增加工受结构类型和二语水平影响,高水平学习者针对介词短语结构采用线性递增模式,针对关系从句结构采用层级递增模式,且层级递增不是由于句法距离效应而是由于分句边界效应引起的;而低水平学习者针对不同结构均采用线性递增模式。实验结果说明二语句子产出中的递增加工模式受二语句法表征影响,具有鲜明的二语特征。

Two experiments using sentence completion tasks were conducted to investigate incrementalplanning strategies during the structural building phase of L2 sentence production among ChineseEnglish learners. The findings show that sentence structure type and language proficiency levelssignificantly influenced incrementality in sentence production. While high-proficiency learnersexhibited variable incrementality strategies tailored to specific sentence structures, adopting alinear approach for projective phrases and a hierarchical approach for relative clause sentences,low-proficiency learners consistently demonstrated linear incrementality across sentence types.Furthermore, the hierarchical incrementality observed in high-proficiency learners was drivenprimarily by clause package effects rather than syntactic distance ffcts. These results underscorethat incrementaltiy in L2 sentence production not only differs from that of native speakers but isalso intricately influenced by learmers' language proficiency.
