【摘要】：结合掩蔽启动范式和ERP技术,利用歧义词素的加工,本研究探讨了歧义词素语义的激活。根据歧义词素类型的不同,将分为两个实验分别进行。实验一中,歧义词素两含义使用频率相当,无主要含义与次要含义之分,采用3×2两因素被试内设计,歧义词素两含义互为启动刺激和目标刺激,两变量分别为启动词类型(歧义词素含义1vs.含义2vs.无关词)和目标词类型(歧义词素含义1vs.含义2)。实验二中,歧义词素两含义使用频率相差较大,有主要含义和次要含义之分,两变量分别为启动词类型(主要含义vs.次要含义vs.无关词)和目标词类型(主要含义vs.次要含义),实验设计同实验一。两实验的行为结果均发现启动词类型和目标词类型存在交互作用,即只有当共享词素同形同义的情况下,目标词的加工才可能被启动。两实验ERP结果有差异,实验一的ERP结果进一步肯定了行为结果,在N250和N400两个脑电成分上都发现了启动类型和目标类型交互作用有关的效应,当启动词和目标词共享词素同形同义时,同时引发了N250和N400的变化;当共享词素同形不同义时,时程分析时虽然也发现了N250的变化,但是N250的效应较小,小于同形同义所引发的N250效应,持续时间也较短。说明了在词汇识别中歧义词素语义可以激活,并对目标词加工的早期加工阶段发挥作用。实验二中,当启动词和目标词共享词素时,可引发N250的变化,启动类型和目标类型的交互作用体现在N400成分上,说明在词汇加工早期阶段可能歧义词素所有语义都是有激活的,只不过语境信息没有发挥选择作用,但在后期整合中确实存在语义信息的激活。
[Abstract]:Based on masking priming paradigm and ERP technology, this paper discusses the activation of ambiguous morphemes by means of processing ambiguous morphemes. According to the different types of ambiguous morphemes, they are divided into two experiments. In experiment one, the two meanings of ambiguous morphemes were used in the same frequency, and there was no difference between the main meaning and the secondary meaning. The 3 脳 2 two factors were used to design the ambiguous morphemes, and the ambiguous morphemes were both priming stimuli and target stimuli. The two variables were the priming word type (ambiguity morpheme meaning 1 vs. Meaning 2 vs. And the target word type (ambiguity morpheme meaning 1) and the target word type (ambiguity morpheme meaning 1 vs. Meaning 2). In experiment 2, the frequency of using ambiguous morphemes is quite different, which is divided into main meaning and secondary meaning, and the two variables are the type of priming word (the main meaning vs.). Secondary meaning vs. Independent words) and target word types (main meaning vs. (secondary meaning), experimental design is the same as experiment one. The behavioral results of both experiments show that there is interaction between the priming word type and the target word type, that is, the processing of the target word can be initiated only when the shared morpheme is identical to the same meaning. The results of ERP were different between the two experiments. The results of ERP in experiment 1 further confirmed the behavioral results. Both N250 and N400 EEG components found the effects related to the interaction between the activation type and the target type. When the priming word and the target word share morpheme homonymy, the changes of N250 and N400 are caused at the same time. When shared morpheme isomorphism and different meanings, the change of N250 was also found in time history analysis, but the effect of N250 was smaller than that of N250 caused by isomorphism, and the duration of N250 was shorter. It shows that ambiguity morpheme semantics can be activated in word recognition and play an important role in the early stage of target word processing. In experiment 2, when initiators and target words share morphemes, the change of N250 can be caused. The interaction between start type and target type is reflected in N400 component, which indicates that all semantics of ambiguous morphemes may be activated in the early stage of word processing. However, contextual information does not play a selective role, but there is activation of semantic information in the late integration.
