Unlike in English, the role of phonology in word recognition in Chinese is unclear. In this event-related potential experiment, we investigated the role of phonology in reading both high- and low-frequency two-character compound Chinese words. Participants executed semantic and homophone judgment tasks of the same precede-target pairs. Each pair of either high- or low-frequency words were either unrelated (control condition) or related semantically or phonologically (homophones). The induced P200 component was greater for low- than for high-frequency word-pairs both in semantic and phonological tasks. Homophones in the semantic judgment task and semantically-related words in the phonology task both elicited a smaller N400 than the control condition, word frequency-independently. However, for low-frequency words in the phonological judgment task, it was found that the semantically related pairs released a significantly larger P200 than the control condition. Thus, the semantic activation of both high- and low-frequency words may be no later than phonological activation.
与英文不同，音韵学在中文单词识别中的作用尚不清楚。在这个事件相关电位实验中，我们研究了音韵学在阅读高频和低频双字复合中文单词中的作用。参与者执行相同前置-目标对的语义和同音判断任务。每对高频或低频单词要么不相关（对照条件），要么语义或音韵相关（同音词）。在语义和音韵任务中，低频单词对诱发的P200成分均大于高频单词对。语义判断任务中的同音词和音韵任务中语义相关的词均比对照条件诱发更小的N400，且与词频无关。然而，在音韵判断任务中，对于低频单词，发现语义相关的词对比对照条件诱发的P200明显更大。因此，高频和低频单词的语义激活可能不晚于音韵激活。
