【摘要】：本研究运用ERP技术，以中文双字词为实验材料，实时记录各项指标，从单独词的呈现方式来探析具体性效应加工的影响因素。本研究共分为两部分：词性对具体性效应的影响研究和频率对具体性效应的影响研究。第一部分考察词性（名词和动词）对具体性效应的影响。在词汇判断任务下，以词性和词汇类型作为自变量，考察两种变量之间的关系。结果发现，N2（150-280毫秒）时程名词和动词开始出现分离；P3（280-420毫秒）时间窗口中名词和动词继续保持加工的差异，并且具体词和抽象词开始出现分离；N400(420-570毫秒)时程中名词与动词的加工、具体词和抽象词的加工仍然存在加工的差异，但是在行为学和脑电的结果中均发现两因素为相互独立的变量。第二部分考查频率（高频和低频）对具体性效应的影响。在词汇判断任务下，以频率和词汇类型作为自变量，考查两种变量之间的关系。结果发现，，N2（150-280毫秒）时间段中高频词汇和低频词汇出现加工分离，P3（280-420毫秒）时间窗口中名词和动词继续保持加工的差异，并且具体词和抽象词开始出现分离；N400(420-620毫秒)时程中名词与动词的加工、具体词和抽象词的加工仍然存在加工的差异，并且行为学数据显示两变量之间存在交互作用。根据以上的实验结果和分析，我们总结出以下结论：（1）中文双字词在单独呈现的情况下，词性（名词和动词）与词汇类型（具体词和抽象词）是两个独立的变量，即词性不影响具体性效应的加工。（2）中文双字词在单独呈现的情况下，频率（高频和低频）与词汇类型（具体词和抽象词）是两个相互联系的变量，即词汇频率影响具体性效应的加工。（3）中文双字词在单独呈现情况下，具体性效应发生在低频词汇范围内。（4）中文双字词的具体性效应的加工不支持双重编码模型，即不支持多重语义系统的观点。
[Abstract]:In this study, using ERP technology, Chinese double-character words as experimental materials, real-time recording of various indicators, from the presentation of individual words to explore the impact of the processing of specific factors. This study is divided into two parts: the influence of part of speech on concreteness and the effect of frequency on concreteness. The first part examines the effect of part of speech (nouns and verbs) on concreteness. Under the task of lexical judgment, the relationship between the two variables is investigated by taking part of speech and lexical type as independent variables. The results show that N _ 2 (150 ~ 280 Ms) nouns and verbs begin to separate, P3 (280 ~ 420 milliseconds) time window continues to maintain the processing differences between nouns and verbs, and concrete words and abstract words begin to separate. The processing of nouns and verbs in the N400 (420 Ms), the processing of specific words and abstract words, is still different. However, both the behavioral and EEG results show that the two factors are independent variables. The second part examines the influence of frequency (high frequency and low frequency) on concreteness effect. In lexical judgment task, frequency and lexical type are used as independent variables to examine the relationship between the two variables. The results show that the processing separation of high-frequency words and low-frequency words appears in N2 (150-280 milliseconds), and the differences between nouns and verbs in P3 (280-420 milliseconds) time window continue, and the separation of concrete words and abstract words begins to appear. The processing of nouns and verbs in N400 (420 / 620 milliseconds), the processing of specific words and abstract words still exist processing differences, and behavioral data show that there is interaction between the two variables. Based on the above experimental results and analysis, we conclude the following conclusions: (1) part of speech (noun and verb) and lexical type (specific word and abstract word) are two independent variables in the case of Chinese double word. That is, the part of speech does not affect the processing of the concreteness effect. (2) the frequency (high frequency and low frequency) and the word type (concrete word and abstract word) are two interrelated variables, that is, the lexical frequency affects the processing of the concreteness effect. (3) the concreteness effect of Chinese double-character words occurs in the range of low-frequency words. (4) the processing of the concrete effect of Chinese double-character words does not support the double coding model, that is, it does not support the multi-semantic system.
