言语产生中的词长效应

采用图片命名方法考察言语产生中的词长效应，并进而分析语音计划的单位和序列性。选取能同时用单音节(如“羊”)和双音节(“山羊”)命名的图片作刺激材料，发现双音节命名明显慢于单音节命名，这种效应既表现在首音节型(如“花”与“花朵”)，也表现在尾音节型(如“羊”与“山羊”)刺激材料上。研究结果支持语音编码从左到右、系列提取和双音节词的词音计划单位大于单音节词的观点。该文还对图片命名中的频率效应进行了事后分析。

WORD LENGTH EFFECT IN SPEECH PRODUCTION OF CHINESE

A picture naming task was used to investigate the word length effect in speech production of Chinese. Pictures that can be named both as single syllable,monomorphemic words and as disyllable,two morphemic compound words,were selected. These pictures were divided into two groups according to whether the monomorphemic words were used as the first or the second constituent morphemes in compound names. Subjects were asked to name the pictures in either monomorphemic names or compound names. A significant length effect was observed for both groups of stimuli,with monomorphemic names pronounced faster than compound names. This finding was interpreted as supporting the view of incremental phonological encoding and planning. A post hoc analysis was also conducted for word and syllable frequency effects in word production.
