藏语母语者汉语词汇识别的眼动研究

An Eye Movement Study of Chinese Word Recognition of Tibetan Native Speakers

采用眼动技术,通过两个实验考察了藏语母语者在不同语境中阅读汉语句子时,字形、语音信息在词汇识别中分别发挥的作用以及词频效应。结果发现:(1)在高限制性句子语境中,字形和语音共同作用;(2)在低限制性句子语境中,语音作用显著;(3)词频效应出现在高限制性语境的晚期,以及低限制性语境的中期和晚期。该结果表明,在藏语母语者阅读汉语的过程中,句子语境影响词汇识别过程中字形、语音的作用及作用的时间进程,藏语母语者汉语词汇识别符合双通道理论。

The present study applied the eye tracking technique to investigate the effects of orthographic and phonological information on the word recognition of Tibetan native speakers while reading Chinese sentences,as well as the effect of word frequency in high or low constraint contexts.The results showed that the orthographic and phonological information jointly influenced word recognition when the context was high constraint.In low constraint context,the orthographic information played an important role on word recognition.The effect of word frequency occurred at the late stage in high constraint context while it was observed at the middle and late stage in low constraint context.These results indicates that the sentence context influences the effects and the time course of orthographic and phonological information on word recognition during the Tibetan native speakers while reading Chinese,which is in support of the two-channel theory of word recognition.
