【摘要】：近年來(lái)，關(guān)于雙語(yǔ)者大腦中兩種語(yǔ)言的轉(zhuǎn)換機(jī)制的研究已經(jīng)成為雙語(yǔ)研究領(lǐng)域的熱門課題。目前關(guān)于雙語(yǔ)轉(zhuǎn)換的研究主要是基于印歐語(yǔ)言展開的，對(duì)漢語(yǔ)的研究較少，并且大多是通過(guò)圖片命名、詞匯判斷等單獨(dú)的詞匯加工來(lái)考察的，缺乏具有語(yǔ)義限制的語(yǔ)境下的研究。 本文采用ERPs（event-related potentials）技術(shù)，考察漢英雙語(yǔ)者在俗語(yǔ)語(yǔ)境和簡(jiǎn)單陳述句語(yǔ)境下對(duì)漢英雙語(yǔ)轉(zhuǎn)換句進(jìn)行閱讀理解時(shí)語(yǔ)言轉(zhuǎn)換的時(shí)間進(jìn)程，分析相關(guān)的ERPs語(yǔ)言成分，以此來(lái)考察語(yǔ)境因素（不同程度的語(yǔ)義限制）對(duì)雙語(yǔ)轉(zhuǎn)換的影響，，并探討雙語(yǔ)轉(zhuǎn)換代價(jià)的來(lái)源問(wèn)題。通過(guò)實(shí)驗(yàn)的分析和討論，我們得出以下一些結(jié)論： 一、通過(guò)比較轉(zhuǎn)換句和無(wú)轉(zhuǎn)換句的行為學(xué)數(shù)據(jù)以及ERPs成分，我們發(fā)現(xiàn)在語(yǔ)言轉(zhuǎn)換過(guò)程中出現(xiàn)了轉(zhuǎn)換代價(jià)。通過(guò)比較兩種不同語(yǔ)境下的漢英雙語(yǔ)轉(zhuǎn)換句，我們發(fā)現(xiàn)轉(zhuǎn)換俗語(yǔ)句和轉(zhuǎn)換簡(jiǎn)單陳述句在早期成分、N400以及LPC成分上都表現(xiàn)出了較為明顯的差異，因此我們認(rèn)為語(yǔ)境因素（不同程度的語(yǔ)義限制）在句子層面的雙語(yǔ)語(yǔ)言轉(zhuǎn)換加工中起著決定性的作用。 二、通過(guò)對(duì)早期成分、N400以及LPC三種成分的分析與討論，我們發(fā)現(xiàn)在語(yǔ)言加工早期的詞匯識(shí)別過(guò)程、詞匯語(yǔ)義整合過(guò)程以及語(yǔ)言加工后期的分析、整合、核查及修復(fù)的過(guò)程中均產(chǎn)生了轉(zhuǎn)換代價(jià)；我們推斷，雙語(yǔ)語(yǔ)言轉(zhuǎn)換代價(jià)部分來(lái)源于雙語(yǔ)大腦詞庫(kù)內(nèi)部的詞匯識(shí)別過(guò)程、詞匯語(yǔ)義整合過(guò)程，部分來(lái)源于大腦詞庫(kù)外部被試的認(rèn)知策略和決策判斷過(guò)程。Green提出的抑制控制模型理論可以解釋本文的實(shí)驗(yàn)結(jié)果，此外我們支持雙語(yǔ)詞匯選擇的非特定語(yǔ)言提取的觀點(diǎn)。
[Abstract]:In recent years, the study of bilingual brain conversion mechanism has become a hot topic in the field of bilingual research. At present, the research on bilingual conversion is mainly based on Indo-European language. There are few researches on Chinese, and most of them are examined by image naming, lexical judgment and so on. This paper adopts ERPs(event-related potentialstechnology. This paper investigates the time course of language conversion in the reading comprehension of Chinese-English bilingual sentences in the context of colloquial language and simple declarative sentences, and analyzes the relevant ERPs language components. In order to investigate the influence of contextual factors (semantic restriction of different degrees) on bilingual conversion, and to explore the source of the cost of bilingual conversion, we draw some conclusions through the analysis and discussion of the experiment. First, by comparing the behavioural data and the ERPs components of transitive sentences and non-transitive sentences, we find that there are switching costs in the process of language conversion, and by comparing two different contexts of Chinese-English bilingual conversion sentences. We find that there are obvious differences in the early components of n400 and LPC between the converted idiom and the simple declarative sentence. Therefore, we believe that contextual factors (semantic constraints to varying degrees) play a decisive role in the process of bilingual language conversion at sentence level. Secondly, through the analysis and discussion of the early components of N400 and LPC, we find that in the early stage of language processing, the process of vocabulary recognition, the process of lexical semantic integration and the later stage of language processing are analyzed. Conversion costs are incurred in the process of integration, verification and repair; We infer that the cost of bilingual language conversion comes in part from the process of lexical recognition and lexical semantic integration within the bilingual brain lexicon. Part of the cognitive strategies and decision judgment process of the subjects from the external brain lexicon. The inhibition control model theory proposed by Green can explain the experimental results of this paper. In addition, we support the idea of non-specific language extraction for bilingual vocabulary selection.
