用跨通道的音-字同音判断任务配以视觉词汇判断作协变分析,实验研究了汉语同音字音节的听觉词汇通达中同音字具体频率和同音字数的相互作用,等同了音节的累积频率和笔画数,结果发现了稳健的同音字族内的词频效应,同音字数与同音字频率相互牵制,表现在同音字数效应缺失,两因素刺激材料难以完全控制新的影响因素产生,出现＂逆＂抑制效应。结果说明在同音字频率和同音字数的相互作用中频率起稳健和主导的作用。

英文摘要：

It is a common phenomenon that one Chinese syllable has more than one corresponding character.However,there is no consistent opinions about the interaction effect of homophone family size and specific-word frequency on the visual lexical access of Chinese homophone.The present study aimed to investigate the interaction effect of homophone family size and specific-word frequency on the auditory lexical access of Chinese homophones,equated cumulative-homophone frequency and the number of stroke. A total of 32 undergraduate students participated in the study.All of them were native speakers of Mandarin Chinese.The experiment was run on IBM computers with E-Prime software.Experiment 1 was a cross-modality syllable-character homophonic judgment task,in which a fixation point＂＋＂was presented on the screen for 500ms,and then a monosyllable sound was displayed binaurally over headphones,which was followed by a visually displayed character.The subjects were asked to perform a syllablecharacter homophonic judgment task as quickly and accurately as possible.Experiment 2 was a visual lexical-decision task,in which a fixation point＂＋＂was presented on the screen for 500ms,and then the target characters used by Experiment 1 were displayed.The ubjects were asked to perform a visual lexical-decision task as quickly and accurately as possible.The reaction time and the error rate were recorded by the computer and analyzed with repeated measure ANOVA.The analysis of covariance（ANCOVA） was implemented with the reaction time and the error rate in Experiment 1 as covariance variables,that of Experiment 2 as dependent variable.All statistic analyses were done by the SAS9.0 software. The results indicated that：（1） Characters with high specific-word frequency were responded to more rapidly and accuracy than characters with low specific-word frequency.（2） A two-way interaction within homophone family size and specific-word frequency showed that the greater the homophone family size was,the less error rate wasonly
