van Galen (1991)的书写产生模型指出书写过程是由层级结构组织起来的多个认知模块平行加工的结果。以此模型为出发点, 介绍了书写产生研究中主要关注的三个问题:书写过程中是否存在语音中介?书写时拼写编码的加工单元是什么?以及书写过程中认知编码阶段和运动执行阶段之间的关系?此外, 我们总结了书写产生与口语产生和阅读之间的联系, 介绍了书写产生过程的认知神经机制。最后, 我们分析了汉语的独特特点, 并指出这些特点对于书写产生研究的重要意义, 期待更多的心理语言学研究关注书写产生这一研究领域。  相似文献

建构统一的认知和神经生理模型是词汇阅读认知神经科学研究面临的核心问题。阅读的认知理论模型一致认为阅读是语音和语义加工通路分工协作的结果,认知神经科学研究也表明词汇阅读是背侧和腹侧神经通路动态协作的结果。为了系统地阐述阅读网络的这种动态协作机制,结合神经功能和生理基础两个层面,从以下三个方面对最新研究进展进行系统疏理:首先,指出潜在的加工需求是背/腹侧神经通路动态协作的实质;然后进一步阐明潜在加工需求驱动了不同正字法深度下背/腹侧神经通路的分工合作模式;最后,深入剖析了潜在加工如何通过语言经验塑造了神经通路间的动态协作。从而揭示出阅读神经通路动态协作的实质可能是特定任务下加工需求驱动的结果,这种动态协作可能成为跨语言普遍的词汇阅读理论模型。  相似文献

计算机的普及使人们阅读及书写的能力降低, 这引发了社会对书写的关注。书写涉及大量高级神经活动, 与认知、人格、疾病等均有关联, 对个体发展也具有重要作用。现代书写心理学通过使用书写板等设备, 实现了对书写过程及结果的量化研究, 发现了书写速度、压力、握笔等指标与智力、认知负荷等的一些关联。未来对书写过程的研究可以进一步深入; 测量方面的研究成果可以应用到日常人机交互及教学、司法等实践中; 还可以研究用书写促进个体认知及人格发展的具体途径。  相似文献

在神经网络的最新取向下, 探讨阅读脑机制中背侧和腹侧通路的协作机制, 是解决语言认知神经科学多个理论问题共同面临的焦点。本项目拟通过两个脑功能成像实验, 建构汉字阅读的动态因果模型, 系统地考察汉字阅读的神经网络, 以及阅读网络中背、腹侧通路的协作机制。实验一利用快速适应实验范式的优点, 识别和考察汉字阅读涉及的认知成分所对应的功能脑区, 以及脑区联结形成的神经回路, 并建构汉字阅读的动态因果模型; 实验二进一步考察在刺激属性(语音和语义信息)和任务要求下阅读脑区的动态激活及相互作用。通过不同任务下的模型对比, 重点探讨阅读网络的脑区联结模式变化, 尤其是背、腹侧通路受刺激和任务影响时的协作机制。研究结果将为揭示阅读的神经生理模型、解决语言特异性脑区激活的争论等理论问题提供直接的证据, 还能为语言教学、阅读障碍矫治、以及临床应用提供理论基础与指导。  相似文献

词汇判断是一种在字词认知研究中广泛使用的实验范式。本文提出了一个基于分布式语义表征的计算模型,用来解释某些在词汇判断作业中出现的实验现象。模型是一个包括词形层、隐层、语义层、词典层和判断层的前传网络。词形层、隐层和语义层之间的连接权重在学习过程中被不断调整,使用反传算法进行学习。语义层、词典层和判断层之间的连接权重在学习前就已被固定,在学习过程中不进行调整。模型模拟了在词汇判断作业中出现的四种实验现象:(1)频率效应;(2)语义启动效应;(3)频率与语境的交互作用;(4)重复启动效应。模型所表现出的行为特性由模型的框架和学习算法所决定。  相似文献

人类在说话或思考的时候常常伴随着手势。手势是在认知加工或交流过程中自动产生的, 具有表征性, 同时, 手势能够影响人类的认知加工。尽管研究者对手势的概念界定各有侧重, 但普遍认为手势不同于直接行动, 具有认知功能。手势认知功能的代表性理论模型有词汇索引模型、信息打包假设、表象保持理论、语义特殊性假设和嵌入/延展观。根据手势认知功能研究中主要自变量的不同, 可以把手势认知功能分成三种不同的研究范式, 即允许-限制手势的研究范式、侧重手势模式改变的研究范式、侧重情境改变的研究范式。今后值得关注的研究方向除了深入探讨手势认知功能的神经机制、加强对手势认知功能的干预研究外, 提出了建立更具解释力的手势认知功能的理论模型——“空间化”手势假设。  相似文献

基于熟练性的认知控制研究认为,双语词汇通达的非选择性和选择性是由于认知控制能力的发展结果。基于语境的认知控制研究认为,语境对认知控制的影响可能发生在词汇通达之后,也可能发生在通达之前,由此造成非选择性和选择性通达。考虑到认知控制能在词汇通达之前就可以利用语境来限制非目标语言的激活,这种结果既与双语交互激活模型关于词汇激活的非选择性假设不一致,也对认知控制能力的发展主要依赖熟练性的看法提出疑问,新的研究也因此被期待  相似文献

Three prominent theories of writing were found in a literature review of Psychlit, educational journals and Medline, and a fourth global theory relating writing to intact cerebral integrity was also hypothesized. These theories were then tested by attempting to predict writing scores among a sample of 44 individuals with academic difficulties. Significant support was found for a memory and attention model, the dysgraphia model, and an abstract sequential analysis model. Surprisingly, measures of the overall cortical integrity were not significantly related to writing behavior in this sample, but this finding may reflect excluding brain damaged subjects in this study. Also, the abstract sequential analysis model appeared to function differently than expected. The results indicate it is important to assess the cognitive contributions of writing difficulties to guide remediation. Larger scale research on the sources of writing disorders is also recommended.  相似文献

The Japanese language is represented by two different codes: syllabic and logographic while Portuguese employs an alphabetic writing system. Studies on bilingual Portuguese-Japanese individuals with acquired dyslexia therefore allow an investigation of the interaction between reading strategies and characteristics of three different writing codes. The aim of this study was to examine the differential impact of an acquired brain lesion on the reading of the logographic, syllabic and alphabetic writing systems of a bilingual Portuguese-Japanese aphasic patient (PF). Results showed impaired reading in the logographic system and when reading irregularly spelled Portuguese words but no effects on reading regular words and nonwords in syllabic and alphabetic writing systems. These dissociations are interpreted according to a multi-route cognitive model of reading assuming selective damage in the lexical route can result in acquired dyslexia across at least three different writing codes.  相似文献

We present SCRIPTKELL, a computer-assisted experimental tool that makes it possible to measure the time and cognitive effort allocated to the subprocesses of writing and other cognitive activities. SCRIPTKELL was designed to easily use and modulate Kellogg’s (1986) triple-task procedure, which consists of a combination of three tasks: a writing task (or another task), a reaction time task (auditory signal detection), and a directed retrospection task (after each signal detection during writing). We demonstrate how this tool can be used to address several novel empirical and theoretical issues. In sum, SCRIPTKELL should facilitate the flexible realization of experimental designs and the investigation of critical issues concerning the functional characteristics of complex cognitive activities.  相似文献

This review is organized in three sections in order to evaluate if expressive writing (namely, to report emotions and deep thoughts concerning positive or negative personal experiences) has a beneficial impact on the physical and psychological well-being of writers. Part 1 reviews studies that showed a beneficial influence of expressive writing. Part 2 is devoted to the examination of the theories for explaining the processes of emotional and cognitive regulation at work during writing disclosure (Disinhibition theory, Cognitive-processing theory, Self-regulation theory, Exposure theory). Findings of several meta-analyses designed to probe the power and validity of results and models are presented. The necessity of a better understanding of the processes by which expressive writing can transform emotional state and intrusive thoughts among writers is examined within the framework of concepts of cognitive psychology involved in writing productions. It is now crucial to use the knowledge of the cognitive approach of written productions for identifying the cognitive-emotional operations that are involved in disclosures and their dependency upon attentional resources of working memory.  相似文献

实验1探究认知负荷(高、低)与编码方式(标准、书写、执行意向)对前瞻记忆的影响,实验2进一步探究其对前瞻记忆两种成分的影响。实验1显示执行意向与书写编码的正确率高于标准编码,而前二者无差异;低负荷的前瞻记忆表现好于高负荷。实验2显示执行意向与书写编码的前瞻成分正确率高于标准编码,而前二者无差异;低负荷的前瞻成分表现好于高负荷;不同认知负荷与编码方式均对回溯成分无影响。结果表明:在意向内容相对简单的情况下,执行意向与书写编码对前瞻记忆的促进作用主要表现在促进前瞻成分的提取,低负荷比高负荷有利于前瞻记忆的成功执行,主要体现在前瞻成分成功率更高。  相似文献

At the behavioural level, the activity of a writer can be described as periods of typing separated by pauses. Although some studies have been concerned with the functions of pauses, few have investigated motor execution periods. Precise estimates of the distribution of writing processes, and their cognitive demands, across periods of typing and pauses are lacking. Furthermore, it is uncertain how typing skill affects these aspects of writing. We addressed these issues, selecting writers of low and high typing skill who performed dictation and composition tasks. The occurrences of writing processes were assessed through directed verbalization, and their cognitive demands were measured through interference in reaction times (IRT). Before writing a narrative, 34 undergraduates learned to categorize examples of introspective thoughts as different types of activities related to writing (planning, translating, or revising). Then, while writing, they responded to random auditory probes, and reported their ongoing activity according to the learned categories. Convergent with previous findings, translating was most often reported, and revising and planning had fewer occurrences. Translating was mostly activated during motor execution, whereas revising and planning were mainly activated during pauses. However, none of the writing processes can be characterized as being typical of pauses, since translating was activated to a similar extent as the other two processes. Regarding cognitive demands, revising is likely to be the most demanding process in narrative writing. Typing skill had an impact on IRTs of motor execution. The demands of execution were greater in the low than in the high typing skill group, but these greater demands did not affect the strategy of writing processes activation. Nevertheless, low typing skill had a detrimental impact on text quality.  相似文献

This study tested the potential to elicit a broadened attentional focus through writing about a positive life experience and to derive health benefits from such writing. Participants (n = 38) wrote for 20 min each day for 3 consecutive days about either a positive life experience or a control topic. Writing about positive experiences led to improved physical health (measured 4–6 weeks after writing) compared to control and higher levels of global cognitive focus after writing mediated this effect. Notably, while the positive writing condition was more broadened than control, positive affect was not responsible for this difference. Implications for disclosive writing and the broaden and build model are discussed.  相似文献

Writing about traumatic events can produce health benefits, yet emotionally non-expressive or cognitively avoidant individuals may be unwilling or unable to express their emotions. This study examined non-expression, cognitive avoidance, response to writing, and subsequent health. As part of a larger study, participants ( N = 71) with asthma or rheumatoid arthritis (RA) wrote about traumatic experiences for 20 min on three consecutive days. Alexithymia, denial, behavioral disengagement, mental disengagement, focus on/venting of emotions, avoidant thoughts, and health status were assessed at baseline, health status again 4 months after writing. Essays were coded for how personal and how emotional they were, and for narrative structure. Non-expression and cognitive avoidance were neither related to how personal or emotional essays were, nor to affective response to writing. High levels of denial or avoidant thoughts predicted less narrative structure. Avoidant thinking marginally predicted health improvements in RA patients. Results suggest that non-expression and cognitive avoidance do not interfere with writing in terms of emotional engagement, but may influence narrative use.  相似文献
