藏-汉-英双语者字词识别中的语码切换及其代价

以母语为藏语、汉语熟练、英语不熟练的藏-汉-英双语者为被试,采用词汇判断的研究范式,在无切换、预期切换和无预期切换三种条件下,考察了藏-汉-英三种语言之间的语码切换及其代价。结果表明：⑴在三种条件下,被试对汉语词和藏语词的反应时和错误率的差异不显著,藏语词和汉语词的切换代价差异不显著。⑵在无切换条件下,对藏语词和英语词的反应时和错误率的差异不显著;在切换条件下,对英语词反应时长,错误率也高;英语词的切换代价显著大于藏语词的切换代价。⑶在无切换条件下,对汉语词和英语词的反应时和错误率的差异不显著;在切换条件下,对英语词反应时长,错误率也高;英语词的切换代价显著大于藏语词的切换代价。整个研究表明,藏-汉-英双语者在字词识别中的语码切换代价主要受语言的熟练程度影响     

维-汉-英三语者三种语言语义通达模型的实验研究

以维吾尔族大学生为研究对象,采用跨语言启动条件下的真假词汇判断任务,变换启动词与目标词的关系类型和语言种类,考察了L2—L1、L3—L1、L3—L2等三种语言词汇之间的语义通达模式。结果发现,维-汉-英三语者的三种语言词汇之间的联结模式为熟练的第二语言词汇是直接通达语义;而非熟练的第三语言词汇既借助母语词汇又借助汉语词汇来通达语义。除此之外,被试的外语熟练水平和语言间的相似性是影响外语词汇通达语义的主要原因。     

启动任务中语言经验对藏-汉双语者主导语的影响

采用语义启动任务及藏语与汉语语义相关词和无关词对,探究语言经验能否改变熟练藏-汉双语者的母语主导优势和双语语义表征方式。结果表明,1)无论启动词为藏语还是汉语,藏-汉双语者对汉语L2目标词的加工速度和正确率均显著好于藏语L1,存在语义启动效应; 而在藏语目标词条件下则未发现显著的语义启动效应; 2)藏语到汉语的语义启动效应大于汉语到藏语的启动效应。结果表明,藏-汉双语者的汉语经验对藏语词的表征有影响,但汉语还不能完全替代母语藏语为主导语,结果在一定程度上支持Kroll的RHM模型和Green的ICM模型。     

藏-汉-英三语者词汇与语义表征研究

采用跨语言长时重复启动范式,考察藏-汉-英三语者词汇与语义表征的特点.结果发现:(1)三种语言的语义属于分布式共享表征,并受语言熟练程度、媒介语影响,表现出词汇与共享概念的不对称性.(2)三种语言的词汇独立表征.     

平衡蒙汉双语者词汇与物理位置空间信息的语义表征

采用空间词不对称判断与Simon任务混合范式考察平衡蒙汉双语者词汇与物理位置空间信息的语义表征特点。实验一以平衡蒙汉双语者为被试,发现Simon效应所受影响在蒙汉语言间无差异。实验二以蒙-汉-英三语者为被试,发现Simon效应所受影响在汉语英语间、蒙语英语间有差异。本研究表明,平衡双语者词汇空间信息与物理位置空间信息存在共享语义表征,语言熟练程度影响一语和二语与共享表征的联结强度,验证了修正层级模型。     

维-汉双语词句阅读顺序对阅读速度的影响

该研究通过采用维-汉两种语言不同书写顺序呈现的词组和句子为实验材料,考察其对维-汉双语者阅读加工速度的影响,为了解维-汉语阅读加工的规律,推动西部双语教学提供科学依据。研究结果表明:(1)在词组水平,对维语的加工速度显著快于汉语,顺意阅读的加工速度要显著快于逆意,按加工速度的快慢顺序为:维语顺意,维语逆意,汉语顺意和汉语逆意词组;(2)在句子水平,维-汉语之间的加工速度无差异显著,但顺意加工速度要显著快于逆意阅读,其快慢顺序为:维语顺意,汉语顺意,汉语逆意和维语逆意句子。这表明词组与句子水平的阅读顺序在不同语言对阅读速度有不同的影响。     

韩-汉跨语言词义水平的重复知盲效应*

关于语义水平的重复知盲效应一直存在争论。本研究考察非平衡韩-汉双语者在语言内和语言间词义水平的RB效应。实验1采用韩语双字词为实验材料探究韩语语言内的RB效应,结果表明在韩语词汇水平存在RB效应。实验2采用两个关键词为韩语（R1）和汉语（R2）双字词,并通过韩-汉语间隔词W的语言类型变化探究韩、汉语言间的RB效应,结果表明：不同语言类型的间隔词的正确率有显著差异,语义重复词R2在重复条件的正确率显著高于非重复条件,出现语义重复启动效应。本研究结论是：（1）在韩语语言内词水平存在RB效应,具有语言类型普遍性;（2）韩、汉跨语言语义水平出现语义重复启动效应,而未发生RB效应,表明双语者在加工韩、汉两种语言时,采用分别形式表征和共享语义表征的方式。     

不同熟练程度藏汉双语者言语理解中的语码切换及其代价

以母语为藏语,第二语言为汉语的熟练和非熟练藏汉双语者为被试,采用词汇判断任务,在无切换、预期切换和无预期切换三种条件下,考察藏汉两种语言之间的语码切换及其切换代价。结果表明：（1）在三种条件下,熟练和非熟练藏汉双语者对汉语词的反应时均显著短于对藏语词的反应时,汉语词的错误率也显著低于藏语词;（2）切换条件下的反应速度显著慢于无切换条件,切换条件下的错误率显著高于无切换条件,存在显著的切换代价;（3）熟练藏汉双语者对汉语词的反应时显著短于非熟练藏汉双语者,熟练藏汉双语者对汉语词反应的错误率也显著低于非熟练藏汉双语者。本研究表明,藏汉双语语码切换过程中存在切换代价,支持抑制说;熟练藏汉双语者语码切换代价更小。     

维吾尔族三语者的非熟练第三语言的概念表征特征

使用跨语言启动条件下的真假词汇判断任务,以母语为维语,第二语言为汉语,第三语言为英语的维吾尔族大学生为被试。通过两个实验探讨了维吾尔族三语者不熟练的第三语言的语义表征特点,即他们的第三语言的语义是共同存储还是独立存储问题。结果发现,跨语言的启动条件下,在实验一,启动刺激（维语）与目标刺激（英语）之间具有语义联想关系时,产生了显著的启动效应。在实验二,启动刺激（英语）与目标刺激（维语）之间没有产生语义启动效应。这些结果表明,被试的第三语言的语义概念表征是同第一语言的概念表征共同存储的;被试的母语较容易启动第三语言,但非熟练的第三语言不太容易启动母语,这是因为被试的第三语言还没有达到一定程度的熟练水平。     

双语平衡度越高，三语音位感知越好？——以哈萨克语-汉语双语者的英语元音学习为例

已有研究对于双语平衡度是否与三语音系习得水平存在联系并未达成一致。本研究以双语平衡度,即哈萨克语-汉语双语者的非优势语言(汉语)熟悉度水平作为自变量,探索其对三语(英语)音位学习的影响。根据双语平衡度水平将被试分为两组,分别完成哈萨克语元音感知、汉语元音感知和英语元音感知任务。结果发现：首先,高、低双语平衡度组的英语元音识别能力不存在显著差别,但其英语元音感知混淆模式存在很大不同,低双语平衡度组的英语元音感知混淆较高双语平衡度组呈现出更为复杂的混淆模式。其次,低双语平衡度组中的优势语言不能有效地解释三语音位感知,非优势语言的音位感知水平对三语音位感知能力的解释率高于高双语平衡度组。这说明双语平衡度影响了三语元音感知。此外,双语间越不均衡,非优势语言的音位感知水平对三语音位感知的解释率越高。     

Semantic access in number word translation: the role of crosslingual lexical similarity

The revised hierarchical model of bilingualism (e.g., Kroll & Stewart, 1994) assumes that second language (L2) words primarily access semantics through their first language (L1) translation equivalents. Consequently, backward translation from L2 to L1 should not imply semantic access but occurs through lexical wordform associations. However, recent research with Dutch-French bilinguals showed that both backward and forward translation of number words yields a semantic number magnitude effect (Duyck & Brysbaert, 2004), providing evidence for strong form-to-meaning mappings of L2 number words. In two number-word translation experiments with Dutch-English-German trilinguals, the present study investigated whether semantic access in L1-L2 and L1-L3 number-word translation depends on lexical similarity of the languages involved. We found that backward translation from these more similar language pairs to L1 still yields a semantic magnitude effect, whereas forward translation does not, in contrast with the Dutch-French results of Duyck and Brysbaert (2004). We argue against a dual route model of word translation and suggest that the degree of semantic activation in translation depends on lexical form overlap between translation equivalents.     

Cross-language activation in children's speech production: evidence from second language learners, bilinguals, and trilinguals

In five experiments, we examined cross-language activation during speech production in various groups of bilinguals and trilinguals who differed in nonnative language proficiency, language learning background, and age. In Experiments 1, 2, 3, and 5, German 5- to 8-year-old second language learners of English, German-English bilinguals, German-English-Language X trilinguals, and adult German-English bilinguals, respectively, named pictures in German and in English; in Experiment 4, 6- to 8-year-old German monolinguals named pictures in German. In both language conditions, cognate status was manipulated. We found that the bidirectional cognate facilitation effect was significant in all groups except the German monolinguals (Experiment 4) and, critically, the child second language learners (Experiment 1) in whom only native language (L1) German had an effect on second language (L2) English. The findings demonstrate how the integration of languages into a child's system follows a developmental path that, at lower levels of proficiency, allows only limited cross-language activation. The results are interpreted against the backdrop of the developing language systems of the children both for early second language learners and for early bi- and trilinguals.     

Performance of bilinguals in a picture-word interference task

The picture-word interference task was administered to Spanish-English adults in order to determine whether the lexicons of bilinguals are integrated or whether words are stored and accessed separately in semantic memory. Pictures were printed with Spanish words naming other objects, with English translations, and with X's. Spanish and English distractor words were observed to slow down picture naming in both languages. Also, an interaction was detected among subjects naming pictures in English. On the first trial Spanish words produced more interference than English words, whereas the pattern was reversed thereafter. This effect is attributed to task novelty, which disappears with practice. No differential patterns of interference were observed among subjects naming pictures in Spanish, probably because of greater error variance. Results for English picture-naming bilinguals supported the integration hypothesis but suggested that there is less distance between words within a language than between languages in semantic memory.     

The influence of second language proficiency on bilingual parallel language activation in Hindi–English bilinguals

We investigated the spontaneous activation of phonologically related words in high and low proficient Hindi–English bilinguals during spoken word processing in an eye-tracking study. Participants listened to spoken words in L1/L2 and looked at a display (consisting of line drawings of phonological cohort of the translation equivalent of the spoken word and unrelated distractors). Both the groups were quick in orienting their attention towards the competitor with the onset of the spoken word. Furthermore, high proficient bilinguals showed higher and earlier activation of the competitor compared to low proficient bilinguals. Cross-language activations were higher in the L2–L1 direction for both the groups. The results strongly suggest language non-selective access of translation in Hindi–English bilinguals in both language directions. We discuss the results with regard to the predictions of the bilingual language processing models and the effect of language proficiency on conceptual access during listening in bilinguals.     

Language acquisition context and language organization in bilinguals

A distinction between compound and coordinate bilingualism has been employed to conceptualize linguistic organization in bilinguals. Compound bilinguals are those who acquired their languages in a joint context and therefore are presumed to store linguistic information interdependently. Coordinates include those who acquired their languages in separate contexts and therefore are presumed to maintain independent linguistic stores. To study the usefulness of this distinction, Spanish-English and English-Spanish, compound, and coordinate bilinguals were asked to give intra-and interlingual free and restricted word associations to equivalent English and Spanish stimuli for which the responses of monolingual speakers were not equivalent. As predicted, compound bilinguals gave significantly more equivalent responses and responded significantly faster than did coordinates. However, since these differences were only modest in size, they cannot be interpreted as supporting the usefulness of the compound-coordinate distinction. None of the predictions regarding the effect of proficiency on performance were supported. Differences as a function of native language, type of association task, and association conditions were obtained and are discussed.This research was supported by USPHS Grant HD 01368 to Dr. Klaus Riegel, University of Michigan, and was included as one portion of a doctoral dissertation submitted by the author to the Horace H. Rackham School of Graduate Studies at the University of Michigan.     

非熟练潮-粤双言者的语义通达：来自听觉词加工的证据

采用听觉跨语言启动的语义判断范式, 考察非熟练潮-粤双言者的两种方言之间的语义通达方式。结果发现, 无论是以潮语词为启动词, 还是以粤语词为启动词, 当二者具有翻译关系时, 启动词均促进对目标词的识别, 但L1对L2的启动量比L2对L1的启动量大。当启动词与目标词具有语义联想关系时, 启动词亦能促进对目标词的识别, 但L1→L2与L2→L1的启动量差异不显著。整个研究表明, 非熟练潮-粤双言者的两种方言的词汇独立表征, 语义共享表征; 第二方言的词汇能够直接通达语义表征, 不需要以第一方言的词汇为中介, 但双言的词汇表征与语义表征的联结强度仍然存在着不对称性。     

三语者语义通达中的跨语言重复启动效应

采用跨语言重复启动的任务范式探讨三语者的语义通达机制。被试为在广州学习汉语的印度尼西亚留学生48名。自变量是学习条件(包括学过与未学过), 因变量是单词判断的反应时和正确率。实验1探讨三语者在视觉与听觉呈现的三语词汇语义通达任务中是否会借助于一语对等词, 结果发现一语词汇在两种任务条件下都能够发挥中介作用, 此结果表明了三语者与双语者语义通达机制的一致性; 实验2探讨三语者在视觉与听觉呈现的三语词汇语义通达任务中是否会借助于二语对等词, 结果发现二语词汇只能在视觉呈现任务条件下发挥中介作用, 此结果表明二语词汇在三语语义通达过程中的中介作用具有限制性。本研究结果表明三语者的语义通达机制与双语者既有一致性, 也有其限制性。     

Language dominance in translation priming: Evidence from balanced and unbalanced Chinese–English bilinguals

It is well established in the masked translation priming literature that the priming effect is sensitive to language direction with noncognates—namely, the priming effect is consistently observed from first language (L1) to second language (L2), but not always from L2 to L1. Several recent reports demonstrated both L1–L2 and L2–L1 priming and attributed the restoration of L2–L1 priming to high proficiency in L2. Here, the current study tested two groups of highly proficient Chinese–English bilinguals, with one group more dominant in English and the other more balanced in both languages. The L2–L1 priming effect was only observed with the balanced bilinguals, but not the English-dominant ones. Based on these results, I argue that the language proficiency account is not sufficient to explain the priming asymmetry and that the relative bilingual balance is a more accurate account. Theoretically, the cross-language balance is determined by the representational difference between L1 and L2 at the semantic level. I discuss the results in relation to various bilingual models, in particular, the sense model and the distributional representational model (DRM), which capture the semantic representations of bilinguals.
