聋生汉字识别的同音判断与启动效应实验研究

本研究采用暂同形似、音同形异、音异形似和无关字四类汉字字组为实验材料．每类字组都按汉字使用频率分为低频字、中频字、高频字三种．对使用手语聋生和使用口语聋生进行了同音判断和启动效应实验，旨在探究聋生在汉字识别过程中语音编码所起的作用。实验结果表明，在聋生汉字识别中，字形的知觉加工对提取语音具有非常重要的作用，但语音的提取对聋生来说非常困难。不同字频对不同字组的同音判断成绩的影响不同，表明聋生对不同汉字的语音意识不同。聋生在汉字识别中存在语音混淆和字形混淆的现象，说明语音编码和字形编码在汉字识别过程中都起了重要的作用。字频对聋生汉字识别的影响也不同，同频字产生语音特征的影响；低频字产生字形特征的影响；而中频字都不产生语音特征和字形特征的影响。

Word Identification by Chinese Deaf Students: Similar Sound Determination and Phonological Activation Study

Two experiments were conducted on short-term recall of printed Chinese characters by deaf students,including students using Chinese signs and oral language.The aim was to investigate the effect of phonological coding on word identification.The results expressed that deaf students have some difficulties in using phonological codes.But phonological confusion effect suggests that deaf students use phonological codes during word identification.And word frequency also influences the extent of phonological coding in word identification.
