摘　　要：本研究探讨汉字刺激质量与语义启动的相互作用,深入考察汉字识别的内在机制。实验采用真假字判断范式,实验1使用语义相关词对比率较高的实验材料,实验2使用语义相关词对比率较低的实验材料。结果发现:(1)无论语义相关词对比率高还是低,均存在语义启动效应和刺激质量效应,且汉字刺激质量与语义启动之间均存在交互作用;(2)轻度模糊刺激较重度模糊刺激受到的语义启动效应更大。结果表明,即使排除了额外反馈的作用,汉字刺激质量与语义启动之间仍存在交互作用,进一步支持交互激活模型。Previously,controversies are observed over the research approach for specific stimulus quality interacted with semantic priming during lexical decision tasks(LDTs),and generally between the Interactive Activation(IA)model and the Multistage Activation(MA)model.Both models involve three stages of processing:feature,letter and word stages.According to the IA model,the processing in each stage feeds activation forward to other stages as soon as activation begins in the original stage(processing is cascaded),accompanied with feedback between adjacent stages.The cascaded activation across representational stages can produce statistic interactions between stimulus quality and semantic priming even when the relatedness proportion(the proportion of semantically related primes to targets)is low(0.25).Compared with forgoing IA model,each stage in MA model will not be activated,before the activation in the prior stage reaches a threshold or the prior processing stops.This model predicts interactions as a result of a strategic retrospective prime retrieval that influences early visual processing only when the relatedness proportion is high.Given that semantic access of a visual word in Chinese system involves less phonological mediation,stimulus quality may possess greater impact on semantic processing via the cascaded processing in Chinese than that in English.Thus,two experiments were performed to test the interactions between stimulus quality and semantic priming in different relatedness proportion during lexical decision tasks.Namely,they were to test if the interactions between stimulus quality and semantic priming occurred regardless of relatedness proportion(i.e.,.5 vs..25).The experiments employed a 2(semantic priming:related vs.unrelated)×2(stimulus quality:blurredness of level 5 vs.blurredness of level 6)design which comprised of 4 treatment conditions.Four stimulus lists were created so that each condition had equal chance when every prime and every target character appeared by rotating the lists across the stude
