【摘要】：随着现代科学技术的进步和先进仪器的出现,有关语义理解加工的研究也开始从单一的平面语法研究转向借助各种信号采集设备,从生理角度开展语言学的相关研究。本文采用事件相关电位(Event-related Potentials, ERP)的技术手段,对有关汉语歧义句理解的脑电信号加以研究,通过对原始脑电信号进行处理、分析,借助潜伏期、幅值、等重要ERP参数来探索大脑的语言加工机制。本文论述了有关汉语歧义现象的研究现状,阐述了本文的研究理论基础和方法,详细介绍了有关ERP技术的原理、研究方法、主要成分、在语言研究中取得的成果和有关本文研究的具体实验方案设计。同时在第四、五、六章中,基于ERP研究的基本参数和研究方式,先后分析研究了大脑对于cl、yy和jf三类歧义句在判断理解过程中显示出的生理活动特征。研究从左额区、右额区以及枕区三方面展开,同时关注Q信号和FQ信号的差异。通过研究发现,在大脑对汉语歧义句理解加工的过程中,Q信号和FQ信号在左额区都会出现P300,且Q信号的P300峰值明显大于FQ信号；右额区Q信号和FQ信号都会出现N200,且Q信号在N200之后还有出现和语义加工相关的N400;在枕区,Q信号和FQ信号趋势相似,但男女被试组间,在波形的走向和峰值出现的时间上各有不同。基于具体参数的考量和比对,本文认为对于歧义句理解的大脑加工活动,在时间进程上,体现出来的是一个从视觉加工到语音加工,再到语义加工的相互融合的过程：同时,基于本文的研究内容和研究结果,发现大脑在汉语歧义句理解的过程中,jf-3和yy-1类型的歧义句相对较难,而yy-2和c1类型的歧义句比较容易。通过对有关三种类型的汉语歧义句大脑理解的研究,本文为进一步弄清有关语言的脑加工机制问题提供了详尽的材料,同时也为今后更加深入地开展有关基于生理角度的语言研究进行了有意义的探索。
[Abstract]:With the development of modern science and technology and the appearance of advanced instruments, the research on semantic understanding and processing is beginning to shift from the single plane grammar research to the use of various signal acquisition devices to carry out the relevant research in linguistics from the physiological point of view.In this paper, Event-related potentials (ERPs) are used to study the EEG signals related to the understanding of Chinese ambiguous sentences. The original EEG signals are processed, analyzed, and the latencies and amplitudes are used.And other important ERP parameters to explore the brain language processing mechanism.This paper discusses the current situation of research on Chinese ambiguity, expounds the theoretical basis and methods of this paper, and introduces in detail the principle, research methods and main components of ERP technology.The results obtained in the language research and the specific experimental design of this study.At the same time, in the fourth, fifth and sixth chapters, based on the basic parameters and research methods of ERP research, we analyze and study the physiological activities of the brain in the process of judging and understanding three kinds of ambiguous sentences: clawy and JF.The study was carried out from the left frontal region, right frontal area and occipital region, while paying attention to the difference between Q signal and FQ signal.It is found that both the Q signal and the FQ signal appear in the left frontal region in the process of understanding and processing Chinese ambiguous sentences, and the peak value of P300 of Q signal is obviously larger than that of FQ signal.The right frontal area Q signal and FQ signal both appeared N200, and Q signal also appeared N400 related to semantic processing after N200. In occipital area Q signal and FQ signal trend was similar, but between male and female subjects,There are differences in the direction of the waveform and the time when the peak occurs.Based on the consideration and comparison of specific parameters, this paper holds that the brain processing of ambiguous sentence comprehension is a process of fusion from visual processing to phonological processing and semantic processing in the process of time: at the same time,Based on the research contents and results of this paper, it is found that it is relatively difficult for the brain to understand the ambiguous sentences of jf-3 and yy-1 types, while the ambiguous sentences of yy-2 and C1 types are easier to understand in the process of comprehension of Chinese ambiguous sentences.Through the study of three types of Chinese ambiguous sentence brain understanding, this paper provides detailed materials for further understanding the brain processing mechanism of language.At the same time, it also makes a meaningful exploration for the further research of physiological angle-based language.
