语境详述能否促进伴随性词汇习得?——来自汉语二语的实证研究

Can contextual elaboration facilitate incidental vocabulary acquisition?An empirical study from CSL

本研究考察了语境详述对中高级汉语二语者伴随性词汇习得的影响。三组语言水平相当的越南汉语二语者分别阅读原始文本、显性详述文本和隐性详述文本,三天后通过词形再认、词形快速判断、语义启动下的词汇判断和词语释义四项任务,测量学习者在阅读中伴随性习得词汇知识的收益。结果表明:(1)语境详述能显著促进汉语二语伴随性词汇知识的习得;(2)显性详述语境对词形和词义知识的习得均有显著帮助,而隐性详述语境仅对隐性词义知识的习得有积极作用;(3)原始文本语境的强度影响不同类型详述语境的效果,隐性详述仅在强语境下才能显著促进隐性词义知识的习得;(4)显性和隐性词汇知识测量工具的使用能更全面地反映语境详述对汉语二语词汇习得的影响。

This study investigats how contextual elaboration impacts the incidental acquisition of vocabulary by intermediate and advanced learners of Chinese as a Second Language(CSL).Three text types,i e.,unmodified,explicitly elaborated,and implicitly elaborated,are presented to three groups of Vietnamese Chinese learners with comparable Chinese proficiency levels.Three days later,the learners incidental vocabulary knowledge gained from the various texts is assessed using four tasks:form recognition,rapid word form judgment,semantic primed lexical decision,and translation.The results show that:(1)The elaborated contexts significantly enhance CSL vocabulary acquisition.(2)Explicitly elaborated contexts play a substantial role in acquiring both form and meaning knowledge,while implicitly elaborated contexts primarily aid the acquisition of implicit meaning knowledge.(3)The contextual richness of the unmodified text affects the effect of different types of elaborated contexts,with implicitly elaborated contexts significantly facilitating the acquisition of implicit lexical knowledge only in informative contexts.(4)Employing both explicit and implicit lexical knowledge measurement tools provides a more comprehensive understanding of the impact of contextual elaboration on CSL vocabulary acquisition.
