维吾尔语形态词汇解码的频率效应

Frequency Effects of Uyghur Morphological Word Decoding

摘要: 本文从心理语言学的角度，通过事件相关电位(ERP)脑电技术，以词汇判断实验范式来研究维吾尔语屈折词和派生词的加工方式。实验材料由高/低频派生词，高/低频屈折词组成。实验材料的词基频率、词长、音节等因素进行严格控制。实验中主要观察被试在加工不同频率的维吾尔语派生/屈折词加工时的电生理数据和行为数据(反应时间)。实验结果显示维吾尔语派生词和屈折词在加工时间进程上有显著差异，行为数据显示高频屈折词的反应时间比低频词快，但高/低频派生词的反应时间没有差异。总之，维吾尔语派生词是整体加工，但是屈折词是进行分解加工。

Abstract: In this paper, from the perspective of psycholinguistics, through the event-related potential EEG technology, with the lexical judgment paradigm, the Uygur inflectional and derivative words processing has been studied. The experimental materials are consisted of high, low frequency derivative words and high, low frequency inflectional words. Base frequency, word length, syllable and other factors of experimental materials are strictly controlled. In the experiment, we mainly investigated the electrophysiological data and behavior data (reaction times) of the subjects in the processing of different frequencies of Uyghur derived and inflected words. The experimental results showed that there are significant differences in the processing time course between Uyghur derivatives and inflectional words. The behavioral data showed that the reaction time of high frequency inflectional words faster than that of low frequency one. But there is no difference in the reaction time of high and low frequency derivatives. In short, Uyghur derivatives are processed as a whole unit, but inflectional words are processed by decomposition.
