语法性别对认知的影响及其机制

语法性是许多语言中普遍存在的现象。它本质上属于句法属性,但是一定程度上关联着语义,而且会影响个体对物体的分类、知觉、认知加工,以及对二语的学习等认知活动,其对认知的影响程度受任务、语言、语法性透明度等因素调节。语法性影响认知的机制主要有概念水平上的相似性假设;生物性假设;词汇水平上的双选择模型。未来的研究要进一步探究语法性的认知机制、二语学习中语法性习得的认知过程、语法性不同形式性别差异影响的机制。     

视觉经验缺失对盲人听觉词汇识别的影响

听觉词汇识别包含复杂的认知加工过程。视觉通道受阻的盲人在听觉词汇加工中具有一定听觉补偿优势; 但由于视觉经验的缺失, 盲人对一些视觉相关词(比如颜色词)的语义加工和理解比明眼人弱。未来的研究应对词汇的视觉相关性进行分类讨论; 对音、形、义等多层面及其神经生理机制进行深入探究, 发展符合盲人感知特点的听觉词汇加工模型; 并拓展不同年龄段的发展性研究。最终, 揭示视觉经验缺失对盲人听觉词汇识别影响机制的全貌。     

认知判断中手部动作模拟的fMRI研究

该研究采用功能磁共振成像技术,考察不同条件下进行工具认知判断时手部姿势对认知判断的影响及动作模拟的神经机制。实验发现：手部姿势存在显著的主效应,冲突手部姿势条件下反应时最慢,且冲突手部姿势条件下与不冲突手部姿势条件下、自然状态条件下反应时存在显著差异,自然状态条件与不冲突手部姿势条件下反应时不存在显著差异。另外,f MRI成像结果发现,额中回、额下回、顶下小叶以及辅助运动区在自然状态下有显著激活,表明个体在进行认知判断过程中有动作模拟过程;海马结构、扣带回及楔前叶等与记忆有关的脑区有显著激活,表明身体经验在认知过程的作用。总的研究表明,不同的手部姿势状态对认知判断有不同影响,冲突手部姿势会对动作模拟产生干扰作用,手部动作模拟的神经机制主要涉及镜像神经元区,且在认知判断时存在具身效应。     

国外现象学与认知科学研究述评

现象学和认知科学有很多差异:其一,两者有各自不同的著述、研究人员、专业机构、词汇、方法等等。其二,有完全不同的初始假设:现象学认为认知的本质在于认知的主观经验,因此致力于描述主观经验的固定结构;而认知科学认为认知的本质在于其神经基础,它致力于寻找认知的因果机制。认知     

句子语境中汉语词汇识别的即时加工过程

视觉词汇的认知加工及语境对这一过程的影响是心理语言学和认知心理学研究的热点。本研究采用眼动方法与ERP技术相结合的手段,考察了句子语境中汉语词汇识别的加工过程。通过六个实验, 探讨了不同限制性语境中汉语词汇形、音的作用及作用的脑机制, 不同偏向性语境对词汇歧义消解的影响及词汇歧义消解的脑机制。该研究结果揭示了句子语境对汉语词汇识别的影响, 提供了眼动方法和ERP技术相结合考察语言认知的研究范例。     

动作记忆：记忆研究的新范畴

动作记忆是伴随动作操作和意识卷入过程的一种记忆活动, 其强调意识卷入状态和操作情景对记忆活动的影响。以往的研究均采用SPT范式探讨动作记忆及其影响因素, 并提出非策略加工、多通道加工、动作编码和情景整合理论以解释SPT效应, 但由于关注角度不同, 所提的理论模型不能全面揭示动作记忆的加工机制。部分研究试图从来源监控方面探究动作记忆的内在机制, 但研究仍然存在分歧。     

网络使用经验对动作动词加工的影响

具身认知理论认为高级概念认知和低级感知觉认知紧密关联, 且两者共享相同的神经系统。本研究设计了3个实验：实验1观察面部表情动词加工是否受面部情绪表达的影响, 结果发现网络使用经验多的被试在促进和抑制面部积极表情条件下对动词的反应没有表现出显著差异。实验2探讨网络使用经验对肢体动作词汇加工的影响, 结果发现网络使用经验多的被试在动词?名词转换时没有产生显著认知损耗。实验3探讨两类被试对正常序列和随机序列图式动词加工是否有差异, 结果发现网络使用经验多的个体对随机序列和正常序列的回忆成绩并无显著差异。本研究从动词认知加工角度验证了高级认知与低级感知觉加工间的紧密联系, 揭示了网络行为与高级认知加工间的相关关系。     

小学儿童词汇知识与阅读理解的关系：交叉滞后研究

对小学1、3、5年级共399名学生进行为期1年的追踪测查, 使用交叉滞后模型检验小学低、中、高年级儿童词汇知识与阅读理解的关系。在控制了语音意识、语素意识、一般认知能力和自回归效应之后, 结果发现：在小学低年级, 词汇知识与阅读理解之间未发现显著的纵向预测关系; 在中年级, 词汇知识和阅读理解存在显著的双向预测关系; 在高年级, T1的阅读理解能够显著预测T2的词汇知识, 而T1的词汇知识对T2阅读理解的预测作用不显著。研究结果表明词汇知识与阅读理解的关系在小学不同年级段存在不同的模式, 这一发现支持了阅读发展阶段论, 并对阅读三角理论进行了一定的补充。     

活动参与在认知损害中的延缓作用

认知损害有关的病理机制、危险因素研究由来已久,但尚未找到有效治疗认知损害的途径,认知损害的保护性因素研究进而成为研究者们关注的热点。前人的研究显示活动参与对认知损害具有积极的影响,可能是认知损害的重要保护性因素,但活动参与对认知损害的影响机制以及各活动之间存在的交互作用仍不明确。未来的研究可着重探讨不同活动类型及其交互作用同认知损害的关系,并分析活动参与对认知损害起保护作用的公共因子。     

通过身体动作理解人与环境:具身的社会认知

近年来,身体与环境的互动、个体认知过程中的情境因素已逐渐成为具身认知领域的研究热点。众多的具身认知研究开始探究何种情境才能有效地启动具身效应。个体的身体感知或者身体动作的变化会对其知觉、情绪等高级心理过程产生无意识的具身效应,认知神经机制的研究显示大脑的运动皮层在这一系列的高级心理过程中发挥了极为重要的作用。本文主要对具身社会认知神经机制的研究进行梳理与分析,旨在从认知神经机制的层面剖析身体动作如何影响个体对人与环境的理解和互动,以及从方法论的角度上思考目前具身认知神经机制的研究现状。     

From perceptual rags to metaphoric riches--bodily, social, and cultural constraints on sociocognitive metaphors: comment on Landau, Meier, and Keefer (2010)

What leads people to describe some of their interpersonal relationships as "close" and "warm" and others as "distant" and "cold"? Landau, Meier, and Keefer (2010) proposed that conceptual metaphors facilitate social cognition by allowing people to use knowledge from a relatively concrete (source) domain (e.g., physical distance) in understanding a different, usually more abstract (target) concept (e.g., love). We concur that such a notion of metaphors can greatly enrich the field of social cognition. At the same time, we believe it is important to devote greater theoretical attention to the nature of metaphorical representations in social cognition. We believe that Landau et al. place too much emphasis on sociocognitive metaphors as top-down knowledge structures and pay too little attention to the constraints that shape metaphors from the bottom up. In the present contribution, we highlight important bottom-up constraints, imposed through bodily constraints and social scaffolds. Sociocognitive metaphors do not exist just for mental representation but for action as well. We discuss the relevance of grounding sociocognitive metaphors for broader motivational purposes.     

生成认知：理论基础与实践走向

生成认知是具身认知思潮中的一个新取向。它主张认知是通过身体活动“生成的” (enacted)。认知的起点不是一个怎样精确表征世界的信息加工问题, 而是行动者在情境中怎样利用知觉来指导自己的行动。认知不是通过精确的心理表征“恢复”世界, 而是通过知觉引导的行动“生成”或“造就”一个自己的世界。认知是具身的行动, 认知结构形成于经常和反复出现的感觉运动模式, 与身体构造和身体活动具有深刻连续性。梅洛·庞蒂的身体现象学对生成认知具有深刻影响。同时, 詹姆斯、杜威等人的实用主义哲学对于实践行动的强调也深刻影响了生成认知。这种认知观强调了“行动”对心智的意义, 引发许多争议, 也促进了心理学研究范式的转变。     

Intersubjectivity and egocentrism: Insights from the relational perspectives of Piaget, Mead, and Wittgenstein

Beginning with Piaget’s concept of egocentrism, we explicate a view of differentiating and coordination perspectives on which language and cognition are based by also drawing on insights from Mead and Wittgenstein. The concept of egocentrism is linked to Piaget’s view of knowledge and development. In overcoming egocentrism, infants differentiate the world from their action. We extend a Piagetian approach to overcoming egocentrism with regard to children’s social knowledge by drawing on Mead’s view that minds and selves emerge from the social process. Children must take the role of others for selves to emerge, a process that is rooted in interaction, requiring sufficient experience with others to be able to anticipate others’ response or attitude to their act. Then the self can respond to one’s own act as the other would. From Piaget’s perspective, these are schemes or patterns of action that develop with repeated experience. From Wittgenstein’s perspective, these patterns are embedded in forms of life; natural ways of reacting to and interacting with others that are characteristic of our species. Overcoming egocentrism or developing perspective taking is required for understanding and for human forms of cognition.     

汉字义符在汉语动作动词意义认知中的作用

通过4个实验,探讨汉字义符在汉语动作动词意义认知中的作用。实验1探讨汉字义符对认知动作动词的动作器官意义的影响。结果表明,当义符与动作器官一致时,会促进对动作动词的动作器官意义的认知;当义符与动作器官不一致时,会抑制对动作动词的动作器官意义的认知。实验2探讨汉字义符对认知动作动词的动作工具意义的影响。结果表明,当义符与动作工具一致时,会促进对动作动词的动作工具意义的认知;当义符与动作工具不一致或无关时,会抑制对动作动词的动作工具意义的认知。实验3探讨汉字义符的作用是否随词频而变化。结果表明,当义符与动作器官一致时,对高频词和低频词动作器官意义的认知不存在显著差异;不一致时,对高频词动作器官意义的认知比对低频词快。实验4探讨汉字义符与动作器官是否一致对具体性不同的动作动词的动作器官意义认知的影响。结果表明,当义符与动作器官一致时,对具体性高的词和具体性低的词的动作器官意义的认知不存在显著差异;不一致时,对具体性高的词的动作器官意义的认知比对具体性低的词快。整个研究表明,汉语动词的结构特点影响对动作动词的动作器官或动作工具意义的认知。     

Implicit social cognition: from measures to mechanisms

Most human cognition occurs outside conscious awareness or conscious control. Some of these implicit processes influence social perception, judgment and action. The past 15 years of research in implicit social cognition can be characterized as the Age of Measurement because of a proliferation of measurement methods and research evidence demonstrating their practical value for predicting human behavior. Implicit measures assess constructs that are distinct, but related, to self-report assessments, and predict variation in behavior that is not accounted for by those explicit measures. The present state of knowledge provides a foundation for the next age of implicit social cognition: clarification of the mechanisms underlying implicit measurement and how the measured constructs influence behavior.     

统计认知理论及应用研究

长期以来大家认为人类认知尽管可以看成是非确定的推理计算过程,但它的知识表达、模型结构、及计算方法和概率统计理论在本质上是不同的,因此认知科学和概率统计方法存在巨大的鸿沟,过去两者基本上独立发展。近年来随着Bayesian概率统计模型研究的一系列突破性工作和认知过程本质的不断被发现和挖掘,两者的相关性和互补性逐渐突显出来。许多研究者认为认知是近似遵循概率统计推理原则的,一些研究工作显示两者的结合有可能对人工智能发展产生深远的影响。本文对当前统计认知理论及应用研究的现状进行系统的梳理,并结合自身的研究对它今后的发展提出自己的看法。     

Editorial: Studies of the Development of Emotion-Cognition Relations

Abstract

This issue of Cognition and Emotion is devoted to studies of the development of emotion-cognition relations. children's knowledge of the causes of emotions, and the relations of that knowledge to expectations or anticipations of emotion experiences. The studies show that infants of seven months display different expressive behaviours to confirmed and disconfirmed expectations; that the first words of 13-month-olds are not coordinated with expressions of joy or negative emotions and 19-month-olds vocabulary spurts contain very few emotion labels; that 3- to 7-year-olds can label their emotions and understand relations among beliefs, desires, and emotion experiences; and that understandings of relations among causal attributions and emotion experiences are stable over the life span. These findings suggest interesting possibilities for research on developmental processes that integrate emotion, cognition, and action.     

A working memory model improves cognitive control in agents and robots

Cognition entails those mental processes enabling understanding the current situation through senses, experience, and thought, and supporting the acquisition of new knowledge. A fundamental contribution in cognition is offered by the working memory, that is a small, short-term memory containing and protecting from interference goal-relevant pieces of information. Grounding our work on biological and neuroscientific studies, we modeled and implemented working memory processes in a software model, IDRA-WM, that can simultaneously act as short-term memory and actions generator, thanks to the use of a reinforcement-driven mechanism for chunk selection. Moreover our system integrates the functions of the working memory with a basic action planner. We tested the model with robot relevant tasks to assess whether the proposed solution can learn to solve a problem on the basis of a delayed reward. The experimental results indicate that IDRA-WM is able to solve even those tasks that do not provide immediate reward after an action.     

Explaining Emotions

Emotions and cognition are inextricably intertwined. Feelings influence thoughts and actions, which in turn can give rise to new emotional reactions. We claim that people infer emotional states in others using commonsense psychological theories of the interactions among emotions, cognition, and action. We present a situation calculus theory of emotion elicitation representing knowledge underlying commonsense causal reasoning involving emotions, and show how the theory can be used to construct explanations for emotional states. The method for constructing explanations is based on the notion of abduction. This method has been implemented in a computer program called AbMaL. The results of computational experiments using AbMaL to construct explanations of examples based on cases taken from a diary study of emotions indicate that the abductive approach to explanatory reasoning about emotions offers significant advantages. We found that the majority of the diary study examples cannot be explained using deduction alone, but they can be explained by making abjuctive inferences. These inferences provide useful information relevant to emotional states.     

Logic and Social Cognition

This article takes off from Johan van Benthem’s ruminations on the interface between logic and cognitive science in his position paper “Logic and reasoning: Do the facts matter?”. When trying to answer Van Benthem’s question whether logic can be fruitfully combined with psychological experiments, this article focuses on a specific domain of reasoning, namely higher-order social cognition, including attributions such as “Bob knows that Alice knows that he wrote a novel under pseudonym”. For intelligent interaction, it is important that the participants recursively model the mental states of other agents. Otherwise, an international negotiation may fail, even when it has potential for a win-win solution, and in a time-critical rescue mission, a software agent may depend on a teammate’s action that never materializes. First a survey is presented of past and current research on higher-order social cognition, from the various viewpoints of logic, artificial intelligence, and psychology. Do people actually reason about each other’s knowledge in the way proscribed by epistemic logic? And if not, how can logic and cognitive science productively work together to construct more realistic models of human reasoning about other minds? The paper ends with a delineation of possible avenues for future research, aiming to provide a better understanding of higher-order social reasoning. The methodology is based on a combination of experimental research, logic, computational cognitive models, and agent-based evolutionary models.
