摘　　要：通过两个语义分类任务,考察词素位置概率信息在中文词汇识别中的作用。实验1以低频词为研究对象,结果发现,在反应时指标上词首词素位置概率效应显著,词尾词素位置概率效应不显著;实验2以高频词为研究对象,结果发现,在反应时指标上首、尾词素位置概率效应均不显著。结果表明,中文词汇加工过程中存在词素位置概率效应,表现为高词素位置概率的词汇加工快于低词素位置概率的词汇,且词首词素位置概率发挥了更大作用。同时,读者对词素位置概率信息的运用受词频影响,在低频双字词的识别中更依赖词素位置概率信息。Understanding the cognitive mechanisms underlying word segmentation has been an important aspect of research on Chinese reading.Accordingly,to obtain insight into the influence of character positional frequency during Chinese word segmentation,we investigated the effects of orthogonally manipulating both initial and final character positional frequency for target words that were of either high or low lexical frequency through two semantic categorization tasks.In Experiment 1,low-frequency words were used to examine the effect of character positional frequency.The results indicated that the initial character positional frequency was significant in reaction time,and had no effect on the final character positional frequency for target words.In Experiment 2,high-frequency words were used to investigate the effect of character positional frequency.The results showed no character positional frequency effect for the initial or final target words.In conclusion,the findings show that the character positional frequency plays a more important role in word processing,which reveals a privileged role for the initial character positional frequency as a cue to word segmentation and recognition.Furthermore,this influence of character positional frequency depends on word frequency;and is only observed for words of lower lexical frequency.
