词根频率和语义透明度对英语二语后缀派生词加工模型影响的实证研究

An Empirical Study on the Influence of Root Frequency and Semantic Transparency on the Processing of English Suffixed-derived Words

本研究采用词汇判断任务,探究词根频率、语义透明度及其交互效应对英语二语后缀派生词加工模型的影响。实验发现:(1)在反应时上词根频率主效应显著,高频词根派生词的平均反应时低于低频词根派生词;(2)在反应时上语义透明度主效应显著,语义透明派生词的平均反应时低于语义晦涩派生词;(3)在正确率上二者交互效应显著,语义透明度对低频词根派生词正确率的影响更大,词根频率对语义晦涩派生词正确率的影响更大。据此,我们构建中国学习者英语二语后缀派生词分解加工模型:分为词素分解和词素整合两个阶段,词根频率和语义透明度均影响派生词加工的时间进程,二者交互影响派生词的加工质量。

This study investigated the influence of root frequency,semantic transparency,and their interactive effect on the processing of English suffixed-derived words.The results showed that:(1)the main effect of root frequency on reaction time was significant,and the derived words with high root frequency were processed faster than ones with low root frequency;(2)the main effect of transparency on reaction time was significant,and the semantically transparent derived words were processed faster than semantically opaque ones;(3)the interactive effect of the two was significant on accuracy rates.Specifically,semantic transparency exerted a greater influence on derived words with low root frequency,while root frequency had a more pronounced impact on semantically opaque derived words.Finally,we presented a decomposition processing model of English L2 suffixed-derived words.The model includes two stages:morpheme decomposition and morpheme integration.Both the root frequency and semantic transparency influence the time course of processing,and interactively influence the processing quality.
