汉英双语者语言产生过程的心理机制研究

Chinese-English Bilinguals’Psychological Mechanism in the Process of Language Production

通过采用图片命名范式探究熟练与非熟练汉—英双语者语言产生过程的心理机制。实验1探讨在单语重复条件下,使用单语命名时,目标刺激的非目标语言库能否得到激活。实验2探讨在双语切换条件下,不同熟练水平双语者在不同切换条件下的行为反应是否存在差异。结果表明:在语言产生过程中,汉英双语者的非目标语言库也会得到激活,并与二语熟练程度无关,激活的范围和程度受非目标语言的熟练程度的影响;在交替使用双语进行命名时,在长时间间隔条件下,提取二语进行命名时的反应时不受二语熟练程度的影响,而正确率会受到影响。未来的汉英双语语言产生研究还可以结合认知神经科学方法,深入探讨语言产生的神经机制。

The psychological mechanism of the language production process was explored in picture naming tasks for Chinese-English bilinguals.In Experiment 1,we investigated whether the non-target word lexicon of the target stimulus could be activated in the context of monolingual repetition.In Experiment 2,we investigated whether there were differences in behavioral responses of bilinguals with different proficiency levels in different switching conditions.The overall results showed that in the process of language production,the nontarget language library of Chinese-English bilinguals would also be activated,which was unrelated with the proficiency of the second language.The range and degree of activation were affected by the proficiency of the non-target language.In addition,the response time of extracting the second language for naming was not affected by the proficiency of the second language in the condition of long time interval,but accuracy was affected.Future studies on the production of Chinese-English bilingual language can also combine cognitive neuroscience methods to further explore the neural mechanism of language production.
