unpredictable condition; switching cost; language production; language comprehension
分别用图片命名和词汇判断任务考察汉英双语者在不可预期条件下进行的语言切换。实验一中,当被试分别用英语和汉语命名图片时,英语和汉语出现了相等的切换代价。实验二中,当被试进行词汇判断时,只有英语出现了切换代价;而汉语没有出现。研究表明,双语者语言产生与理解中切换的认知过程有本质的差异且预期条件的变化影响了语言产生中的切换。
分彆用圖片命名和詞彙判斷任務攷察漢英雙語者在不可預期條件下進行的語言切換。實驗一中,噹被試分彆用英語和漢語命名圖片時,英語和漢語齣現瞭相等的切換代價。實驗二中,噹被試進行詞彙判斷時,隻有英語齣現瞭切換代價;而漢語沒有齣現。研究錶明,雙語者語言產生與理解中切換的認知過程有本質的差異且預期條件的變化影響瞭語言產生中的切換。

Picture naming and lexical decision tasks were used to investigate the processing of code switching in Chinese-English bilinguals under unpredictable conditions.In experiment 1,the subjects were required to name the pictures in English or Chinese.The results showed an equal switching cost both for both Chinese and English.In experiment 2,the subjects made decision by pressing the left or right key.The pattern of switching cost changed,showing a significant switching cost for English but not for Chinese.These results demonstrate that the switching process of language comprehension is different from that of language production.The switching cost in language production is mediated by the factor of expectation.
