【摘要】 以往研究已经证实熟练双语者在只使用一种语言的情况下,另外一种语言词汇也得到了激活。当前的研究采用事件相关电位技术探讨在图词干扰范式下词汇产生的时间进程。研究中采用的被试是生活在汉语环境下的维语-汉语双语者,实验要求使用汉语对图片进行命名,而忽视图片中呈现的汉语干扰词。结果发现,当分心词和图片命名词存在语义相关或是语音相关时(不管是在一语词汇还是二语词汇相关的情况下),比分心词和图片命名词不存在语义或是语音相关的情况下,被试的反应要慢。同样对N2成分(195—270ms)和N3成分(360—400ms)的平均振幅观察也表明词汇产生的过程中是存在干扰的。这些结果支持了双语者言语产生中非选择性通达的模型,即在二语背景条件下的言语组织的过程是存在竞争的。更多还原

【Abstract】 Prior research has proved that cross-language activation is present even when proficient bilinguals perform a task only in one language.The present study explored the time-course of cross-language activation during word production in a second language (L2)by using a picture-word interference paradigm with event-related potentials(ERPs).Uigur-Mandarin bilinguals living in an L2 environment named pictures in their L2 Mandarin.while ignoring L2 Mandarin noise words that were visually presented with the pictures.Participants named pictures more slowly when noise words were semantically related or phonologically related to either the Mandarin name of the picture or the Uigur name of the picture than when picture and noise words were unrelated.Interference was also observed in the mean amplitude of the N2 peak(195-270 ms) and the N3 range(360-400ms).The results indicated that lexical alternatives from both languages compete forselection in the process of L2 speech planning in a predominantly L2 context.更多还原
