汉语音节累积词频对同音字听觉词汇表征的激活作用

【摘要】：汉语同音字音节的累积词频是同音单字词的具体词频之和,即音节作为词被听到的频数,也称为音节词频。它对词汇通达的作用还没获得一致看法。本文探讨听觉词汇通达中同音字表征的激活如何受累积词频的影响,构成累积词频的具体词频和同音字数又会在其中起何作用。研究采用跨通道的音-字同音判断范式和配套的协方差分析分离出听觉的词汇表征激活作用。实验1固定同音字数,同时变化累积词频和具体词频(其中具体高、低频同时也是同音字族内的高、低频),结果发现具体词频的提高对表征激活有积极作用;累积词频的提高仅在错误率上产生微弱的抑制作用,而这个微弱作用可以归结为同音字族内高频字表征的激活对低频字表征的抑制。实验2固定具体词频,同时变化累积词频和同音字数,结果发现同音字数增加对表征激活产生抑制,没有发现累积词频的作用。两个实验的结果说明,音节累积词频对同音字的听觉词汇表征激活不起确定作用,能够起作用的是同音字族内的具体词频和同音字数;但同音字数变化的抑制作用仅在具体词频不变时才发生,因此起决定作用的是同音字族内高频字表征激活和低频字表征抑制的机制。
[Abstract]:The cumulative word frequency of Chinese homophonic syllable is the sum of concrete word frequency of homophonic words, that is, the frequency of syllable being heard as a word, also known as syllable frequency. It does not agree on the role of lexical accessibility. This paper discusses how the activation of homophonic word representation in auditory lexical access is affected by the cumulative word frequency, and how the specific word frequency and homophonic word number of the cumulative word frequency play a role in it. In this study, auditory lexical representation activation was separated by cross-channel phonem-word homonym judgment paradigm and covariance analysis. In experiment 1, the number of homophonic words was fixed, and the cumulative word frequency and specific word frequency were changed simultaneously. The results showed that the increase of specific word frequency had a positive effect on the activation of representation. The increase of cumulative word frequency has only a weak inhibitory effect on the error rate, and this weak effect can be attributed to the suppression of the low frequency word representation by the activation of the high-frequency word representation in the homonym family. In experiment 2, the specific word frequency was fixed and the cumulative word frequency and homonym word number were changed simultaneously. The results showed that the increase of homophonic word number inhibited the characterization activation, but no effect of cumulative word frequency was found. The results of the two experiments show that the cumulative syllable frequency can not determine the activation of the auditory lexical representation of homophones, but it is the specific word frequency and the number of homophones in the homonym family that can play a role. However, the inhibitory effect of homophones only occurs when the specific word frequency is invariant, so it is the mechanism of high frequency word representation activation and low frequency word representation suppression that determines the function of homophones.
