老年人医疗语篇理解的影响因素和补偿模型

医疗语篇理解是老年人实现自我照护的关键因素,改善老年人医疗语篇理解有助于提高其生存质量并节约医疗成本。本文整理了老年人医疗语篇理解的影响因素,包括加工能力等老年人个体因素和可读性等语篇设计因素,并在此基础上提出了老年人医疗语篇理解补偿模型。该模型尝试阐述上述各影响因素中,那些随龄衰退的因素(如加工能力),如何从别的因素中得到补偿(如医疗知识),从而支撑老年人的医疗语篇理解。补偿模型有利于干预研究的设计,但也还有待更多的实证研究。     

语篇连接词的连接性及其在广义论证中的作用CSSCI

语篇连接词研究有三种主要理论进路:弗雷泽(Fraser)的一般理论、希夫林(Schiffrin)的连贯论以及布莱克莫尔(Blakemore)的关联论。三者认同语篇连接词的连接性,却对其给出了不同的解释。这种解释差异的根源在于,语篇连接词在三种理论框架下中有不同的功能设定:在一般理论里其用于标示语篇元素的语义关系,在连贯论里其用于建立文本结构,而在关联论里其用于引导与话语解释相关的认知推理。因此,语篇连接词实际上有三种连接性:语义连接性,结构连接性和认知连接性。这三类语篇连接性有助于理解鞠实儿提出的"广义论证",即论证是语篇序列。     

情境模型与语篇理解研究

70年代以来,随着认知科学的发展,尤其是受知识表征研究的影响,人们逐渐把语篇理解看作一个心理表征的建构过程。然而,直到80年代早期,许多认知心理学家仅把语篇理解看作语篇自身的一个心理表征的建构和提取,而不是语篇描述的情境的建构和提取。van Dijk和Kintsch最先提出了情境模型(situation model)这一概念,并区分了语篇表征的三个层次：表层编码(surface code)、课文基础表征(textbase)和情境模型。表层编码表征的是语篇中的字、词、短语以及它们之间的语言学的关系;课文基础表征则包含文章准确意义的一系列命题,是对文章所提供的语义及等级层次关系所形成的表征;而情境模型则是在课文基础表征和读者的背景知识相互作用下经推理而形成的内容或心理上的微观世界。     

语篇理解中语境对代词理解的影响

该研究考察了语篇理解中整体语境和局部语境对代词理解的影响。向被试呈现语篇,其中包括带有语义偏向的整体语境和局部语境以及代词。要求被试判断代词的所指。结果发现,当代词和整体语境出现时,被试并不立刻判断,等局部语境也出现以后,才判断代词的先行词。这一结果支持“首先建立句子袭征,再把句子表征与语篇表征相整合”的分阶段加工观点。     

语篇情绪理解及其认知神经机制

在心理语言学领域,情绪信息加工是语篇理解的重要方面,得到了广泛关注。目前的研究表明,读者在语篇阅读中可以在线地、自动地推测出语篇情绪信息,追踪情绪信息的变化,并对其进行更新。语篇理解相关的模型及一些事件相关电位(ERP)的实证研究表明语篇情绪理解至少包括两个重要的加工过程:一是对语篇情绪信息的实时监控,二是对当前情绪信息的评估与更新。相关的功能磁共振(f MRI)的研究表明语篇情绪理解除了需要经典的情绪加工网络,还需要多个脑区网络的参与,如,语篇理解网络、心理理论(To M)网络。未来研究还需更加深入地、更加细致地探讨语篇情绪理解的认知神经机制及其可能的影响因素,研究成果也可以为情感计算领域提供一定的借鉴。     

不同语言理解能力中学生的语篇连贯推理

该研究使用移动视窗技术考察了初二和高一年级中的高低语言理解能力被试语篇阅读过程中将当前信息与背景信息之间建立联系,建构语篇连贯表征的连贯推理加工特点。结果表明：(1)不同语言理解能力个体对语篇中明确提及信息的记忆无差异,但在阅读过程中进行连贯推理上存在差异。(2)个体进行连贯推理的速度和准确度会随年龄增加有所提高。     

语篇中代词指代的研究进展

代词的指代在语篇局部连贯性中具有关键作用。中心理论是代词指称中的重要理论,它解释了语篇中代词的分布规律;注意驱动理论是在中心理沦的基础上结合重音预设解释重音或非重音代词。影响代词指称的因素有语义因素和结构因素。对代词的认知研究另一方面主要集中在对歧义代词的解释．对歧义代词的解释的研究一方面采用重复姓名不利实验范式,另一方面的研究采用的研究方法是探测词任务。在汉语中对代词的研究主要是对文本语篇的研究。     

语篇阅读理解的推理机制研究

１语篇阅读理解的推理研究何以受到重视近些年来,在语篇（ｔｅｘｔ）层次上进行阅读理解的推理研究受到了相当程度的重视。究其原因,可以概括为以下几个方面：第一,对语篇阅读理解的研究是认知心理学对言语理解研究不断深人的结果。认知心理学在其产生时注重的是字词理...     

左右半球在语篇理解中的协同作用

通过2例一侧颞叶损伤患者研究了一侧颞叶损伤及两侧半球的协同作用对语篇理解的影响,并探讨了发生此种影响的可能机制。结果表明一侧颞叶的损伤将导致患者语篇水平的理解障碍及语言推理能力的下降;提示语篇理解需双侧半球的协同作用,而推理能力下降可能是引发语篇理解障碍的原因之一。     

韵律特征研究

介绍从知觉、认知和语料库分析角度对汉语韵律特征进行的一系列研究。（1）韵律特征知觉：用实验心理学和知觉标注的语料库分析方法,研究汉语语调和音高下倾与降阶问题,语句和语篇中知觉可以区分的韵律层级及相关的声学线索。研究结果支持汉语语调的双线模型理论和语句音高下倾的存在;证明语篇中知觉可以区分的韵律边界是小句、句子和段落,及其知觉相关的声学线索。（2）韵律特征与其他语言学结构的关系：在标注的语料库的基础上,用常规统计方法研究语句常规重音分布规律、语篇信息结构与重音的关系、并用决策树方法研究根据文本信息确定韵律短语边界和焦点的规则。（3）韵律特征在语篇理解中的作用：用实验心理学方法和脑电指标研究韵律对语篇信息整合和指代理解的影响,揭示其作用的认知和神经机制。讨论了这些研究结果对语音工程、语音学理论和心理语言学研究的实践和理论意义     

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。     

Reading skill and the identification of words in discourse context

Word identification latencies and word prediction accuracy were compared for groups of skilled and less skilled young readers in three experiments. In each experiment, discourse context reduced identification latencies for less skilled as well as skilled readers. This was true both when context was heard and when it was read. The general relationship between word predictability and latency was the same for skilled readers and for less skilled readers, but only less skilled readers’ identification latencies were affected by word length and word frequency when the word appeared in context. When subjects predicted the word before identifying it, correctly predicted words were identified more quickly than words not predicted correctly, and skilled readers were more accurate in prediction than were less skilled readers. Although reading-related differences in the use of discourse context may characterize other aspects of reading comprehension, the use of context in identifying words is not a major source of reading difficulty.     

语篇背景在语义整合中的作用

通过眼动实验考察了语篇背景对不同类型句子语义整合过程的影响。句子类型有3个水平：(1)宾语违反了动词的选择性限制; (2)宾语符合选择性限制, 但是违反了世界知识; (3)无违反。语篇背景有2个水平：(1)中性背景; (2)校正背景。在中性语篇背景下, 句子(1) (2)是不合适的; 而在校正背景下, 三种句子都是合理的。24名大学生被试自然阅读的眼动数据表明, 违反动词选择性限制的目标词上的首次注视时间、回视路径时间和总注视时间, 在中性背景下比在校正背景下长, 注视点个数也更多; 而在非选择性限制违反条件下, 语篇背景的效应只在总注视时间和注视点个数两个指标上显著。这些结果表明, 当句子中的宾语违反了动词的选择性限制时, 语篇背景影响了宾语的早期和晚期加工。而当宾语只违反世界知识时, 语篇背景的作用体现在晚期阶段。语篇背景对当前信息的整合是动态的过程, 并不是只能在固定某个阶段起作用。     

Age differences in resolving anaphoric expressions during reading

One crucial component of reading comprehension is the ability to bind current information to earlier text, which is often accomplished via anaphoric expressions (e.g., pronouns referring to previous nouns). Processing time for anaphors that violate expectations (e.g., 'The firefighter burned herself while rescuing victims from the building') provide a window into how the semantic representation of the referent is instantiated and retained up to the anaphor. We present data from three eye-tracking experiments examining older and younger adults' reading patterns for passages containing such local expectancy violations. Younger adults quickly registered and resolved the expectancy violation at the point at which it first occurred (as measured by increased gaze duration on the anaphor), regardless of whether sentences were read in isolation or embedded in a discourse context. Older adults, however, immediately noticed the violation only when sentences were embedded in discourse context, suggesting that they relied more on situational grounding to instantiate the referent. For neither young nor old did prior disambiguation within the context (e.g., stating the firefighter was a woman) reduce the effect of the local violation on early processing. For older readers, however, prior disambiguation facilitated anaphor resolution by reducing reprocessing. These results suggest that (a) anaphor resolution unfolds serially, such that prior disambiguating context does not 'inoculate' against local activation of salient (but contextually inappropriate) features, and that (b) older readers use the situational grounding of discourse context to support earlier access to the antecedent, and are more likely to reprocess the context for anaphor resolution.     

Exploring the contribution of the cerebral hemispheres to language comprehension deficits in adults with developmental language disorder

A divided visual field, priming paradigm was used to observe how adults who have a history of developmental language disorder (DLD) access lexically ambiguous words. The results show that sustained semantic access to subordinate word meanings (such as BANK-RIVER), which is seen in control subjects, is disrupted in the right cerebral hemisphere for this special population of readers. In the left hemisphere, only the most dominant meaning of the ambiguous word shows sustained priming in both controls and DLD participants. Therefore, for the DLD readers the subordinate meanings of words are not primed in either hemisphere and, thus, may not be available during online processing and integration of discourse. This right hemisphere lexical access deficit might contribute to the language comprehension difficulties exhibited by adult readers with a history of DLD.     

Two Strands of Scholarship on Language Comprehension: Phoneme Monitoring and Discourse Context

This paper briefly reviews two areas of work on language comprehension and gives an informal assessment of each. One area discussed is phoneme monitoring, a method for measuring on-line spoken language comprehension. The origins of this method are sketched, as are some of the ways in which it has been used and the assumptions behind its use. The second area is substantive rather than methodological, being concerned with discourse context and its effect upon word and sentence processing. The hypothesis of interest states that discourse context has its effects on subsequent word processing primarily by affecting the ease of integrating new information into the ongoing discourse representation. This organizationally based view is distinct from a more elementaristic one which states that context operates by items priming other individual items. Some work consistent with the integration perspective is noted.     

语篇语境对句子理解的影响：来自N400的证据

N400作为语义违反的特异性ERP组分,其波幅反映了语义整合加工过程的难度,因此可将其作为研究语篇语境意义建构过程的一项重要指标。语篇语境可分为语言语境和非语言语境。前人一系列基于语篇水平的N400研究表明,从语义的角度上看,语言语境对句子理解具有制约和协调作用,其机制涉及词汇语义启动、场景适宜性、文字内容信息以及因果推理等方面;非语言语境对句子理解具有制约和补充作用,但其机制尚不明确。两种不同来源的语义信息在实时理解中是同时得到加工的     

Age differences in resolving anaphoric expressions during reading

ABSTRACT

One crucial component of reading comprehension is the ability to bind current information to earlier text, which is often accomplished via anaphoric expressions (e.g., pronouns referring to previous nouns). Processing time for anaphors that violate expectations (e.g., ‘The firefighter burned herself while rescuing victims from the building’) provide a window into how the semantic representation of the referent is instantiated and retained up to the anaphor. We present data from three eye-tracking experiments examining older and younger adults' reading patterns for passages containing such local expectancy violations. Younger adults quickly registered and resolved the expectancy violation at the point at which it first occurred (as measured by increased gaze duration on the anaphor), regardless of whether sentences were read in isolation or embedded in a discourse context. Older adults, however, immediately noticed the violation only when sentences were embedded in discourse context, suggesting that they relied more on situational grounding to instantiate the referent. For neither young nor old did prior disambiguation within the context (e.g., stating the firefighter was a woman) reduce the effect of the local violation on early processing. For older readers, however, prior disambiguation facilitated anaphor resolution by reducing reprocessing. These results suggest that (a) anaphor resolution unfolds serially, such that prior disambiguating context does not ‘inoculate’ against local activation of salient (but contextually inappropriate) features, and that (b) older readers use the situational grounding of discourse context to support earlier access to the antecedent, and are more likely to reprocess the context for anaphor resolution.     

话题结构对语篇情绪累加的影响

在阅读理解的过程中,读者能够自动对语篇中的情绪进行推断。本研究采用自定步速阅读的方法,分别在外显和内隐两种情绪加工的任务下,考察话题结构对语篇情绪累加的影响。结果发现,在实验一的外显情绪判断任务下,话题结构未显示出对语篇情绪累加的明显作用;在实验二的内隐情绪理解任务下,当话题延续时,读者对有两个情绪线索的语篇的阅读时间短于仅有一个情绪线索的语篇,此时情绪的累加促进了当前句的加工,而话题转换时,二者没有显著差异,说明此时读者在新结构下建立当前句的情绪表征,并不在先前情绪的基础上进行累加。     

The Effects of Sentence‐Level Context,Prior Word Knowledge,and Need for Cognition on Information Processing of Technical Language in Print Ads

An experiment was conducted to examine the effects of sentence‐level context, prior word knowledge, and need for cognition on responses to print ads for technical products. Words and phrases that help readers understand technical language in context increased the supportive arguments generated in response to ads, whereas prior word knowledge and need for cognition primarily influenced neutral thoughts. Only explanatory language facilitated the comprehension of product information. Explanatory language led to an increase in attitudes and purchase intent. Need for cognition had a positive influence on attitude formation when the context language was ambiguous, but decreased attitude formation when the context language was explanatory. Results are consistent with predictions guided by a comprehension elaboration model of persuasion.
