汉语阅读中先行词词频对代词加工影响的眼动研究

采用眼动分析法考察先行词词频对代词加工的影响。结果表明,先行词的词频对其代词加工的难易没有影响,即当先行词为高频词时对代词后区域的阅读时间与低频条件没有差异。研究结果支持了代词加工的词条重新通达假说,该理论认为读者在加工代词时只需通达先行词的部分词汇信息。     

性别刻板印象表征的形式及神经基础

本实验采用ERP技术,考察性别刻板印象的表征。结果发现,无论启动是上位范畴、子范畴、典型样例还是反例,被试对于刻板印象不一致的表征比一致的表征均诱发了波幅更大的N400,反应时更长。并且,被试对于性别刻板印象的表征存在层级差异。研究结果表明：（1）性别刻板印象的表征存在层级结构。（2）语义启动下,性别刻板印象违背诱发N400效应。（3）性别刻板印象表征存在自上而下的由大脑额叶进行的语义分类加工。     

刻板印象的激活效应:行为和ERPs证据

以刻板印象表征中的核心内容——刻板特质词作为研究材料,采用分类-确认范式对刻板印象激活效应的时间进程及其认知机制进行了探讨。以性别范畴词"男"/"女"作为启动刺激,以性别刻板特质词作为靶子,特质词与范畴词构成一致和冲突两种情境,记录了34名被试(男女各半)对特质词与范畴词进行一致性判断时的行为反应和ERPs。结果发现:(1)刻板印象冲突情境下,因刻板印象激活效应的作用,被试的反应时要比刻板印象一致情境下更长;不同性别的被试均表现出性别内群体范畴词激活优势效应,即内群体范畴词启动条件下反应时更短。(2)刻板印象激活效应对早期ERP成分(P1、N170、N100、P2)没有影响,在刻板印象冲突情境下诱发了额-中区更显著的N400,该成分标志着刻板印象的激活效应;不同性别的被试均在内群体范畴词启动下诱发了波幅更大的P600。(3)刻板印象的激活效应以及内群体范畴词激活优势效应均发生在知觉后阶段。     

动词隐含因果性对代词加工的影响

本研究探讨了在汉语句子理解中动词隐含因果性对代词指认的影响。在实验一巾,被试进行自定步速的阅读．结果发现当动词隐含因果性和句中代词实际所指一致时阅读时间较短,不一致时阅读时间较长。实验二采用眼动技术,句中两个参与者性别不同,代词上提供性别线索,结果显示了动词隐含因果性在代词加工上微弱的即时效应。     

影响代词加工的语义和语法因素研究

句子的语义、代词与其先行词的语法功能一致性、先行词是否是句子的主语等因素对代词加工有何影响。结果表明,语义是影响代词加工的主要因素。被试基本上根据语义信息确定代词的所指。代词和先行词的语法功能相同只在某些特定条件下加速代词的加工。代词加工中的相同功能原则在研究结果中得到部分支持。先行词是否是句子的主语或指首先提及的对象也在一定程度上影响先行词的确定和确定的速度。     

中文词类信息在副中央凹中的加工

本研究采用边界范式, 通过操纵预视词和目标词的词类一致性探讨中文阅读中副中央凹中能否加工词类信息。实验采用单因素3水平设计, 三种预视条件: 一致预视、词类不违背预视、词类违背预视。对实验数据进行线性混合模型及贝叶斯分析发现: 词类违背条件和词类不违背条件下对目标词的注视时间和注视概率没有显著差异, 即无词类信息的预视效应。该结果倾向于支持序列注意转移模型, 眼动控制模型的未来发展应更加关注灵活性和普适性。     

印象形成中交叉刻板印象的加工机制

以大学生作为被试,旨在探究：在交叉刻板印象加工过程中,是否存在某一单维刻板印象的加工优势效应？如果存在,靶子熟悉度的差异是否会影响单维刻板印象的加工优势效应？该单维刻板印象加工优势效应是否还会受到其他单维刻板印象加工的调节。研究结果表明：（1）在对具有性别-年龄组合而成的交叉刻板印象的人群进行判断时,通过面孔进行启动,发现在不同的条件下分别存在性别单维刻板印象和年龄单维刻板印象的加工优势效应,即年轻男性或女性面孔的性别特征较年龄特征更容易得到加工和提取,老年男性或女性面孔的年龄特征较性别特征更具有加工优势。而在范畴词汇启动下,老年男性或女性词汇启动下的年龄特征较性别特征更具有加工优势。（2）熟悉性会影响单维刻板印象的加工优势,即在年轻被试感知面孔或范畴词汇时,其对老年男性或女性靶子间击中率的差异要显著大于对年轻男性或女性的靶子间击中率的差异。换言之,年轻被试感知老年人靶子的性别与年龄间的差异要显著大于年轻人靶子,出现自我参照现象。（3）在交叉刻板印象加工中,同时存在的各类单维刻板印象加工是彼此削弱的,具有优势加工效应的刻板印象的加工会受到非优势刻板印象加工的抑制。（4）在交叉刻板印象加工中,优势刻板印象加工会受到其相对刻板印象加工的削弱。     

词切分对日-汉双语者汉语阅读影响的眼动研究

以24名日-汉双语者为被试, 采用EyeLink2000眼动仪, 通过两个实验来探讨词切分对日-汉双语者汉语句子阅读的影响。实验一采用四种词切分方式：正常条件、词间空格条件、非词空格条件和字间空格条件。为了确保四种词切分条件下句子的空间分布一致, 实验二采用灰条标记作为字、词或非词的边界。结果发现：(1)在总体和局部分析中, 词间空格条件下平均注视时间显著少于正常条件; 非词空格和字间空格条件下的阅读时间更长、注视次数更多。(2)在总体分析中, 总句子阅读时间和总注视次数在正常条件和词间空格条件中差异不显著; 局部分析中, 词间空格条件比正常条件下的阅读时间更短、注视次数更少。表明日-汉双语者在阅读词间空格文本和正常文本一样容易; 词切分对日-汉双语者汉语阅读的词汇识别有促进作用; 在汉语阅读中, 词是重要的加工单位。     

词切分对初学者句子阅读影响的眼动研究

采用EyeLink II眼动仪,以72名小学三年级学生为被试,通过三个实验来探讨词切分对初学者汉语句子阅读的影响。实验一设置四种空格呈现条件:正常的无空格条件、字间空格条件、词间空格条件和非词空格条件。实验二采用灰条标记作为字、词或非词的边界,使不同条件下句子的空间分布是一致的。实验三进一步操纵了学生的阅读技能。结果发现三个实验的结果趋势是一致的。小学三年级学生在阅读有词间空格的文本和正常的无空格文本一样容易。尽管词切分文本对阅读技能高和阅读技能低的学生来说一样容易,但非词空格呈现条件会对阅读技能低的学生产生更大的干扰作用。阅读技能低的学生在阅读过程中更依赖于文本的低水平视觉线索。文章最后讨论了词切分对建构中文阅读眼动控制模型的启示。     

词切分对日-汉和汉-日双语者日语阅读影响的眼动研究*

选取24名日-汉和24名汉-日双语者,采用EyeLink2000眼动仪,探讨日-汉和汉-日双语者阅读有词切分线索的日语文本的眼动特征,研究词切分线索对日-汉和汉-日双语者日语句子阅读的影响。研究包括两个实验。实验一采用三种词切分方式：正常条件、词间空格条件和非词条件。为了确保三种词切分条件下句子的空间分布一致,实验二采用灰条标记作为词或非词的边界。结果表明,日语文本中加入词间空格促进汉-日双语者日语文本的阅读。     

Comprehending pronouns: a role for word-specific gender stereotype information

The research investigated how word-specific gender stereotype information can be used during language comprehension. In a rating study, the gender stereotypes for 405 noun and noun compounds were assessed. From these norms, 32 words strongly stereotyped to refer mostly to males and 32 words strongly stereotyped to refer mostly to females were selected and used in a reading experiment. Comprehenders read pairs of sentences. The subject of the first sentence was a gender stereotyped word (e.g., executive or secretary). The subject of the second sentence was either the pronoun he or she. Reading time was significantly longer when gender of the pronoun mismatched the gender stereotype of the antecedent than when the genders of pronoun and antecedent matched. This gender mismatch effect occurred on the two regions immediately following the region containing the pronoun. The results indicated that word-specific gender stereotypes can influence coreference resolution of pronouns.     

常识性知识和语篇语境对代词指认的影响

本研究围绕中文代词理解中, 读者的常识性知识和语篇语境的作用以及作用时程这一问题展开。实验1首先探讨在中文阅读理解中, 职业性别倾向这种常识性信息是否能对代词的指认产生早期影响。存在一致和冲突(如警卫-他; 警卫-她)两个实验条件, 结果在凝视时间、重读时间和总阅读时间上都发现了职业性别倾向所引发的性别冲突效应。实验2在实验1基础上增加一个代词(如：警卫-他-他; 警卫-她-她), 考察更正后的信息, 即文本语境内容是否可以覆盖常识的作用对代词加工产生影响。结果发现语篇语境确实可以覆盖常识性信息的作用, 对代词加工产生早期影响。但是, 职业性别倾向这种常识性知识仍然在代词加工的后期阶段发挥作用。考虑到代词所形成的语境较为含蓄, 实验3中采用更明确的方式来界定职业名称的性别, 例如男艺人、爸爸等, 然后再出现一个代词, 代词的性别始终和先前的性别描述一致, 而与职业性别倾向冲突, 这样也存在一致和冲突两个条件(例如：保姆-妻子-她, 警卫-妻子-她), 结果发现只有更正后的语境信息对代词加工产生影响, 职业性别倾向不再发挥作用。说明在中文这种高语境依赖性的语言文字中, 语境可以覆盖常识性知识对代词加工产生早期作用。但是, 语境作用的持续性问题会受到语篇语境中性别信息明确程度的影响。     

Capacité de mémoire de travail et traitement du pronom chez l’enfant

The aim of this study was to explore the relationship between working memory capacity (WMC) and reading comprehension in children by testing the processing of pronouns. Two groups of nine- to ten-year-old children classified as high span and low span were administered a pronoun processing task. In this task, the computation of the antecedent referent for pronouns was varied by manipulating the distance between the pronoun and its antecedent and the availability of a gender cue. The results showed that compared to high-span children, low-span children experienced more difficulties in computing a pronoun's referent. High-span children spent longer reading sentences containing anaphoric pronouns when pronouns could not be resolved on the basis of the gender alone, suggesting that the pronouns were resolved as they were read. Low-span children tended to delay resolution until it was required by the task. In the question-answering times, low-span children were more adversely affected by distance than high-span children. Altogether these findings support the view that working memory capacity constrains resolution of anaphoric pronouns in children.     

Violating stereotypes: Eye movements and comprehension processes when text conflicts with world knowledge

We investigated the effect of discourse context on the access of word meaning during reading. Target words were role names (e.g., electrician) for which there was a gender stereotype (e.g., electricians are stereotypically male). Target sentences contained a reflexive pronoun that referred to the role name (e.g., The electrician taught herself ...). Participants read these target sentences with or without paragraph context while their eye movements were monitored. In the absence of discourse context and in neutral discourse contexts, fixation times on the reflexive pronoun and immediately following the pronoun were inflated when the pronoun specified a gender that mismatched the stereotype, indicating that the gender stereotype was activated upon encountering the role name. When prior discourse context indicated the gender of the role-named character, this mismatch effect was eliminated. The mismatch effect indicates that gender stereotypes are automatically activated in the absence of disambiguating information. The lack of an effect when gender has previously been specified is consistent with the lexical reinterpretation model proposed by Hess, Foss, and Carroll (1995).     

Effects of antecedent order and semantic context on Chinese pronoun resolution

Three reading time experiments were conducted in order to examine the relative contributions of order of antecedents and semantic context to the resolution of temporarily ambiguous Chinese pronouns. These pronouns were ambiguous because each of them was preceded by two antecedents, both of which were likely candidates for coreference. The identity of the pronoun was revealed by subsequent disambiguating information that constrained the pronoun to one particular interpretation. Experiment 1 showed that reading of the disambiguating phrase was slower when the phrase confined the pronoun to the second rather than to the first antecedent. Experiment 2 produced the same effect of antecedent order (first vs. second antecedent) regardless of whether the target antecedent was an action-performing or an action-receiving entity. In Experiment 3, the order effect was eliminated by a biasing modifier inserted immediately before the pronoun. These results indicate that in a semantically neutral environment, the first-appearing antecedent is the preferred candidate for coreferencing the ambiguous Chinese pronoun. The interaction between order of antecedents and semantic context (in the form of preposed biasing modifiers) suggests that the initial comprehension of Chinese pronouns depends as much on contextual as on structural factors.

Accessing singular antecedents in conjoined phrases

Two experiments examined processing of singular pronouns when the antecedent (e.g., Mary) was a noun phrase (NP) in a conjoined phrase (e.g., Mary and John). Whole-sentence reading times showed an increase in processing time associated with splitting the conjoined phrase to access a single NP antecedent. The increase in processing occurred both when the antecedent was in the subject position and when it was in a nonsubject position. The source of the disruption was further investigated using eyetracking methods. Summing over regions of the text, the magnitude of the processing cost incurred by having to split a conjoined NP was closely comparable when there was and when there was not a gender-appropriate distracting potential antecedent. When there was no such potential antecedent, the increase in processing time occurred immediately in the pronoun region when eye movements were measured. In contrast, when there was a second discourse entity that matched the gender and number of the pronoun (but was not a plausible antecedent for the pronoun), eyetracking measures suggested that the processing difficulty was delayed until additional information was read that forced the antecedent to be one of the conjoined NPs. The results are interpreted in terms of Sanford and Garrod’s (1981) scenario-based model of text comprehension.     

Processing biological gender and number information during Chinese pronoun resolution: ERP evidence for functional differentiation

There have been a number of behavioral and neural studies on the processing of syntactic gender and number agreement information, marked by different morpho-syntactic features during sentence comprehension. By using the event-related potential (ERP) technique, the present study investigated whether the processing of semantic gender information and the processing of notional number information can be differentiated and to what extent they might interact during Chinese pronoun resolution. The pronoun (with singular form in Experiment 1 and with plural form in Experiment 2) in a sentence matched its antecedent or mismatched it with respect to either biological gender or notional number or both. While the number mismatch elicited a P600 effect starting from 550 ms (for singular pronoun) or 400 ms (for plural pronoun) post-onset of the pronoun, the gender mismatch elicited an earlier (for singular) and larger (for both singular and plural) P600 effect. More importantly, the double mismatch produced a P600 effect identical to the effect elicited by the single gender mismatch. These results demonstrate that biological gender information and notional number information are processed differentially and have different processing priorities during Chinese pronoun resolution.
