【摘要】：刺激質量和語義啟動的相互作用有兩種模式,即交互作用和加法效應。在一些條件下,刺激質量和語義啟動表現(xiàn)為交互作用,在一些條件下,刺激質量和語義啟動表現(xiàn)為加法效應。多階段激活模型和交互激活模型都可以解釋刺激質量和語義啟動的相互作用。在語義相關比例為0.5的條件下,多階段激活模型和交互激活模型都假設刺激質量和語義啟動應表現(xiàn)出交互作用,但在語義相關比例為0.25的條件下,兩模型的理論假設出現(xiàn)分歧,多階段激活模型預測刺激質量和語義啟動表現(xiàn)出加法效應,交互激活模型預測刺激質量和語義啟動仍然表現(xiàn)出交互作用。交互激活模型和多階段激活模型最大的區(qū)別在于交互激活模型包含串聯(lián)加工,本文的研究目的即是檢驗串聯(lián)加工的正確性,解決多階段激活模型和交互激活模型的爭論,考察多階段激活模型和交互激活模型哪一個能夠更好地解釋詞匯識別過程。本文包含兩個實驗,均使用漢字作為實驗材料,實驗一在語義相關比例為0.5的條件下,研究刺激質量和語義啟動的相互作用,與以往的研究進行對照,為實驗二奠定基礎。實驗二使用漢字作為實驗材料,在語義相關詞對所占比例為0.25的條件下,研究漢字識別中刺激質量與語義啟動在N400上的相互作用,考察串聯(lián)加工是否正確,解決多階段激活模型和交互激活模型的爭論。 兩實驗采用語義啟動范式,要求被試判斷靶字和探測字是否為同一字,在靶字呈現(xiàn)時不需立即作出反應,直到探測字呈現(xiàn)才需作出反應,為延遲反應的同一字判斷任務,可以避免決策相關成分P300對N400的混淆。 實驗一包含兩個因素,語義啟動(語義相關和語義無關)、刺激質量(模糊5水平和模糊6水平),語義相關比例為0.5,在被試完成同一字判斷任務的同時,記錄對靶字的腦電反應。行為結果表明,語義啟動主效應顯著,語義相關靶字比語義無關靶字的反應時短,正確率高：刺激質量主效應顯著,模糊6水平的靶字比模糊5水平的靶字反應時短,正確率高；刺激質量和語義啟動的交互作用不顯著。腦電結果表明,刺激質量和語義啟動在N400上出現(xiàn)交互作用,啟動條件下的刺激質量效應比無啟動條件下的刺激質量效應更大；語義相關靶字比語義無關靶字引發(fā)更小的N400,出現(xiàn)語義啟動效應；模糊6水平的靶字比模糊5水平的靶字引發(fā)更小的N400,出現(xiàn)刺激質量效應。漢字出現(xiàn)刺激質量的N400效應,說明漢字識別中存在串聯(lián)加工,而英文沒有刺激質量N400效應,漢字和英文具有不同的內在加工機制,英文可能存在語音夾層。 實驗二包含兩個因素,語義啟動(語義相關和語義無關)、刺激質量(模糊5水平和模糊6水平),在實驗一的基礎上增加280對語義無關字對作為填充刺激(不進行分析),使語義相關比例達到0.25。行為結果與實驗一基本一致,語義相關靶字比語義無關靶字正確率高,出現(xiàn)語義啟動效應；模糊6水平的靶字比模糊5水平的靶字反應時短,正確率高,出現(xiàn)刺激質量效應；刺激質量和語義啟動的交互作用不顯著。腦電結果表明,刺激質量和語義啟動在N400上表現(xiàn)出交互作用,啟動條件下的刺激質量效應比無啟動條件下的刺激質量效應更大。按照多階段激活模型的預期,在語義相關比例為0.25,并且被試意識到語義相關比例低的情況下,刺激質量和語義啟動應該表現(xiàn)出加法效應,與本實驗結果不相符,不支持多階段激活模型。本文的實驗結果,在語義相關比例為0.5和0.25的條件下,刺激質量和語義啟動均出現(xiàn)N400上的交互作用,刺激質量和語義啟動的交互作用不受語義相關比例的影響,表明串聯(lián)加工是正確的,符合交互激活模型的預期,支持交互激活模型。
[Abstract]:There are two modes of interaction between stimulus quality and semantic priming, namely, interaction and addition effects. In some conditions, stimulation quality and semantic priming are interacted. In some conditions, stimulation quality and semantic priming are additive effects. Both multistage activation model and interactive activation model can explain the quality of stimulation and the interaction activation model. The interaction of semantic priming. Under the condition of semantic correlation ratio of 0.5, both the multi stage activation model and the interactive activation model assume that the stimulus quality and the semantic priming should show interaction, but the theoretical hypothesis of the two model is disambiguation under the condition of the semantic correlation ratio of 0.25, and the multistage activation model predicts the quality of stimuli and the language. The interaction activation model predicts the interaction between the stimulation quality and the semantic priming. The biggest difference between the interaction activation model and the multistage activation model is that the interactive activation model contains the series processing. The purpose of this study is to test the correctness of the series processing, and to solve the multistage activation model. The argument of interactive activation model, which examines the multi stage activation model and the interactive activation model which can better explain the process of vocabulary recognition. This paper contains two experiments, all of which use Chinese characters as experimental materials, and the experiment one studies the interaction between stimulus quality and semantic priming under the condition of the semantic correlation ratio of 0.5, and the previous research. The experiment two lays the foundation for experiment two. Experiment two use Chinese characters as experimental materials. Under the condition that the proportion of semantic Related words is 0.25, the interaction between stimulus quality and semantic priming in Chinese character recognition is studied, and the correctness of series processing is investigated, and the dispute of multi stage activation model and interactive activation model is solved.
Two the experiment adopts the semantic priming paradigm, which requires the subjects to judge whether the target word and the detection word are the same word, and do not respond immediately when the target word is presented, until the detection word is presented before the response is required. It can avoid the confusion of the decision related component P300 to the N400 by the same word judgment task for the delayed response.
Experiment one consists of two factors, semantic priming (semantic correlation and semantic irrelevance), stimulation quality (fuzzy 5 level and fuzzy 6 level), and semantic correlation ratio of 0.5. The EEG response of the target word is recorded while the subject is completed the same word judgment task. The behavioral results show that the semantic priming effect is significant and the semantic related target words are more than the semantic irrelevant targets. The response time of the word is short and the correct rate is high: the main effect of the stimulation quality is remarkable, the target word of the fuzzy 6 level is shorter than the target word with the fuzzy 5 level, the correct rate is high, the interaction effect of the stimulation quality and the semantic priming is not significant. The EEG results show that the stimulation quality and the semantic priming appear on the N400 interaction and the stimulation quality effect under the starting condition. The effect of the stimulation quality is greater than that in the non start condition; the semantic related target words are smaller than the semantic unrelated target words, and the semantic priming effect appears. The fuzzy 6 level target word is smaller than the fuzzy 5 level target word, which leads to the effect of the stimulation quality. The N400 effect of the Chinese character's stimulation quality shows the existence of the Chinese character recognition. Serial processing, while English does not stimulate the quality of the N400 effect, Chinese characters and English have different internal processing mechanisms, and there may be voice dissection in English.
Experiment two contains two factors, semantic priming (semantic correlation and semantic irrelevance), stimulation quality (fuzzy 5 level and fuzzy 6 level), and adding 280 pairs of semantic independent word pairs as filling stimuli (no analysis) on the basis of experiment one, which makes the semantic correlation ratio reach 0.25. behavior result basically consistent with experiment one, semantic related target word ratio Semantic unrelated target characters have high correct rate and semantic priming effect; the target word of fuzzy 6 level is shorter than the target word with fuzzy 5 level, the correct rate is high, the stimulation quality effect is high, the interaction effect of the stimulation quality and the semantic start is not significant. The EEG results show that the stimulation quality and the semantic priming show interaction and starting conditions on the N400. Under the expectation of the multi stage activation model, when the semantic correlation ratio is 0.25, and the subjects realize that the semantic correlation ratio is low, the stimulation quality and the semantic priming should show the addition effect, which does not agree with the results of the experiment, and does not support the multistage excitation. The experimental results of this paper are that the interaction between stimulus quality and semantic priming is N400 under the conditions of semantic correlation ratio of 0.5 and 0.25. The interaction between stimulus quality and semantic startup is not influenced by the semantic correlation ratio, which indicates that the series processing is correct, conforms to the expectation of interactive activation model and supports interaction activation.
