汉语母语者和二语学习者双音节名词产出的编码进程及影响因素研究

A study of the encoding process and influence factors of the production of bi-syllabic nouns between Chinese native and second language speakers

本文通过图词干扰的图片命名实验,以及基于实验结果构建的贝叶斯结构方程模型,考察了汉语母语者和二语学习者双音节名词产出的词条选择和音韵编码的时间进程,以及影响命名速度的汉语水平、工作记忆容量、语速等个体差异因素。研究结果发现:第一,汉语母语者的词条选择和音韵编码符合独立两阶段模型,二语者符合非离散模型。其原因可能是产出不同语言时音韵编码单元的不同。第二,随着汉语水平的提高,说话者词条选择的时间进程会逐步提前,语速也会逐渐加快。第三,由于控制性注意的参与强度不同,工作记忆容量在不同干扰条件下对口语产出的影响不同。本研究深化了对汉语口语产出的认识,可以为汉语二语口语教学提供一些建议。

In this study we adopted the Picture Word Interference paradigm, and constructed Bayesian structural equation models based on experimental results to explore the time course of lemma selection and phonological encoding process of oral production, as well as the roles of the language proficiency, working memory capacity and speed of speech in production. The main findings of the study include:(1) The lemma selection and phonological encoding process of Chinese native speakers conformed to the independent two-stage model, while the second language speakers conformed to the non-discrete model, which may result from the differences of phonological encoding unit when producing different languages;(2) As the Chinese proficiency of the speakers improved, the time course of the speakers’ lemma selection would gradually be advanced, so the speed of speech would be faster;(3) As the intensity of participation in controlled attention was different, working memory capacity played different roles under different interference conditions. This study deepened understanding of the production process of spoken Chinese and provided suggestions for second language teaching of spoken Chinese.
