【摘要】：結(jié)合掩蔽啟動(dòng)范式和ERP技術(shù),利用歧義詞素的加工,本研究探討了歧義詞素語(yǔ)義的激活。實(shí)驗(yàn)采用3×2兩因素被試內(nèi)設(shè)計(jì),歧義詞素兩含義互為啟動(dòng)刺激和目標(biāo)刺激,兩變量分別為啟動(dòng)詞類型(歧義詞素含義1 vs.含義2 vs.無(wú)關(guān)詞)和目標(biāo)詞類型(歧義詞素含義1 vs.含義2)。行為結(jié)果發(fā)現(xiàn)啟動(dòng)詞類型和目標(biāo)詞類型存在交互作用,即只有當(dāng)共享詞素同形同義的情況下,目標(biāo)詞的加工才可能被啟動(dòng),共享詞素同形不同義時(shí)并沒(méi)有產(chǎn)生啟動(dòng)效應(yīng)。ERP結(jié)果進(jìn)一步肯定了行為結(jié)果,在N250和N400兩個(gè)腦電成分上都發(fā)現(xiàn)了啟動(dòng)類型和目標(biāo)類型交互作用有關(guān)的效應(yīng),當(dāng)啟動(dòng)詞和目標(biāo)詞共享詞素同形同義時(shí),同時(shí)引發(fā)了N250和N400的變化;當(dāng)共享詞素同形不同義時(shí),時(shí)程分析時(shí)雖然也發(fā)現(xiàn)了N250的變化,但是N250的效應(yīng)較小,小于同形同義所引發(fā)的N250效應(yīng),持續(xù)時(shí)間也較短。實(shí)驗(yàn)結(jié)果說(shuō)明,在詞匯識(shí)別中歧義詞素語(yǔ)義可以激活,并對(duì)目標(biāo)詞匯加工的早期加工階段發(fā)揮作用。
[Abstract]:Based on the masking priming paradigm and ERP technique, the semantic activation of ambiguous morphemes is investigated by using the processing of ambiguous morphemes. The experiment was designed with 3 脳 2 factors. The meanings of ambiguous morpheme were priming stimulus and target stimulus, and the two variables were priming word type (ambiguous morpheme meaning 1 vs.). Implication 2 vs. Irrelevant word and target word type (ambiguous morpheme 1 vs.) Meaning 2). The behavior results show that there is interaction between the priming word type and the target word type, that is, the processing of the target word can only be initiated when the morpheme is shared with the same meaning. There was no priming effect when sharing morpheme isomorphism. The ERP results further confirmed the behavioral results, and the effects related to the interaction between the priming type and the target type were found in both N250 and N400 EEG components. When the initiator word and the target word share morpheme synonyms, the changes of N250 and N400 are initiated at the same time. Although the change of N250 is also found in time history analysis, the effect of N250 is smaller than that of N250 induced by synonym, and the duration is shorter. The experimental results show that ambiguous morpheme semantics can be activated in lexical recognition and play an important role in the early processing stage of target lexical processing.
