自我-他人表征：共享表征还是特异表征?

自我-他人表征是自我在与他人交往时所形成的自我概念, 为深入研究自我和他人关系提供了一个新视角。自我-他人表征有共享表征和特异表征两种主要观点。前者认为主体将对有关他人信息的表征融入到自我概念之中, 成为自我的一个组成部分。自我和他人信息的加工共享着某些激活脑区。后者则认为主体对自我表征和他人表征是相对独立的, 两者都有各自特定的表征方式和结构。自我和他人相关信息加工的脑区是特定的。此外, 自我-他人共享表征和特异表征的关系、情绪与情感在自我-他人表征的作用和关系类型与程度对自我-他人表征的影响等都是未来研究的重点。

语义表征具身理论:情绪在概念表征中的作用

概念如何被表征是认知科学的热点问题,其中抽象概念如何表征是当前具身认知最具争议性的话题之一。与前期概念隐喻理论(强调意象图式)和知觉符号理论(强调情境内省信息)的观点不同,语义表征具身理论强调情绪经验信息在抽象概念表征和加工中的作用。具体而言,具体概念的表征主要来自感觉运动信息,而抽象概念的表征主要来自情绪经验信息和语言信息。研究证明,抽象概念的高情绪经验信息能够促进词汇的加工,且这一促进作用受词汇情绪效价的调节。未来研究应进一步考虑影响情绪经验信息发挥作用的因素,比如语言信息的丰富性、情绪唤醒或个体的情绪状态等。     

两种自我保护机制：记忆忽视和自我免疫

当自我概念的稳定性受到威胁时,人们有时会采取自我保护手段来加以应对。在诸多自我保护方式中,记忆忽视加工是指个体在接触具威胁性的信息时进行选择性记忆,自然地忽视此类信息而不让其进入精加工,以消除该信息对自我概念的伤害;自我免疫加工是指个体通过对具威胁性信息的适宜操作界定来强调自己的优势能力,并重新评估自己的弱点,从而策略性地实现自我概念的稳定。文章从两种加工的认知机制角度来介绍和评述该领域的研究概况、研究方法与研究展望,借以引起对自我保护机制研究新进展的关注     

平滑追踪眼动及其对运动物体时空特征表征和预测的影响

平滑追踪眼动是人们对环境中感兴趣的运动物体进行持续视觉追踪的一种眼动行为, 它受个体在其过程中获得的视觉信息和眼动反馈信息等感知觉因素, 以及心理表征和期待等高水平认知因素的影响。同时, 平滑追踪眼动过程影响着个体的预测性眼动追踪、追赶性眼跳、空间定位和接触时间估计等涉及运动物体时空特征表征和预测的行为。未来的研究应注意探讨在平滑追踪眼动过程中获得的感知觉信息和高水平认知因素对上述时空特征表征和预测行为的影响。     

统计概要表征的内容与机制

人类能够快速提取集合刺激中的统计信息, 并形成以集中趋势和变异性为主要内容的统计概要表征。根据注意资源的使用, 统计概要表征的加工方式可分为分布式注意下的整体加工和聚焦注意下的个体加工。两种加工在工作记忆中相互影响, 共同构建了对集合刺激的表征。统计概要表征适用于多种刺激类型, 发生在低水平和高水平加工中, 因而可能是一种普遍的知觉加工方式。未来研究可关注统计概要表征的神经基础及其对决策的影响。     

5-9岁儿童自传记忆与自我概念的发展及其关系

自传记忆是关于个体生活事件的记忆,与个体的自我组织结构相互影响。为在同一文化背景下进一步探讨自传记忆与自我概念发展的关系,文章采用访谈的方式,对81名5-9岁儿童进行访谈,结果发现：（1）年龄较大儿童的自传记忆更丰富、具体,涉及更多的他人信息。（2）自我概念在一年级到三年级之间发展迅速。（3）儿童自传记忆与自我概念发展无显著的性别差异。（4）自传记忆与自我概念在多方面存在显著相关。     

质量表征和眼动过度追踪对表征动量的影响

人们对运动目标最终位置的记忆常常会向运动方向发生偏移, 这种偏移被称为“表征动量”。现有研究对表征动量的解释涉及从低水平的知觉加工到高水平的认知加工等多个方面。本研究采用不同材质和滚动声音的球体作为刺激材料, 考察高水平的质量表征对表征动量的影响以及知觉水平的眼动信息在其中的作用。实验1探讨了对目标质量的主观表征对眼动追踪和表征动量的影响。结果显示, 质量表征会同时影响眼动追踪和表征动量。实验2通过不同的提示线索控制眼动追踪, 进一步探讨眼动过度追踪对表征动量的影响。我们发现, 非自然追踪的条件下, 表征动量会减小, 且质量表征对表征动量的影响不再显著。本研究结果表明, 高水平的质量表征对表征动量的影响会通过知觉水平的眼动过度追踪起作用; 然而, 表征动量还受其它因素影响, 眼动信息并非决定表征动量的唯一因素。     

多元表征假设：概念表征机制的新观点

传统的认知主义认为概念表征是与主体的感知系统无关的抽象符号。而具身理论则认为,概念表征以主体的感觉、知觉运动系统为基础的,感知系统在概念表征中具有中心作用。然而,具身性假设无法恰当的解释抽象概念表征这一问题。这种局限性说明主体的概念系统可能具有多元表征机制：既包括感知表征以加工与身体经验相关的具体知识,也包括抽象符号表征以加工与身体经验无关的抽象知识。来自病理学、认知神经科学和行为实验的实证研究证明了不同类型的概念会涉及不同的表征机制,证实了多元表征存在的合理性。今后的研究应探讨各种表征机制之间的关系等问题。     

常识问题任务中理解他人的加工机制

理解他人是指推断他人的心理状态,以及解释和预测他人行为的心理加工。本研究采用常识问题任务,通过三个实验来考察成人理解他人的加工机制,提出并验证双加工模型。研究发现:第一,个体在理解他人的过程中综合考虑了自我信息和他人信息,提出并验证了双加工模型。第二,反馈作用会改变个体自我模拟所获得的自我信息,从而影响理解他人。第三,他人信息将影响自我对他人的推断预测,片面的他人信息会导致理解他人出现偏差。     

三重自我建构的神经机制

三重自我建构理论（the tripartite model of self-construal）认为,自我包含三个方面：个体自我,关系自我和集体自我;三种自我同时存在。研究发现：相比其他信息,三种自我均诱发了更强的N2（熟悉度指标）、P300（高级认知加工指标）成分以及与自我加工有关的MPFC脑区;个体自我存在右脑优势,而集体自我则存在左脑优势。但其具体表征脑区,其在中国文化背景下的文化特异性,以及不同关系类型、群体范畴是否能进一步划分关系和集体自我等问题均有待探讨。     

Conceptual Organization of Self-representation: A Self-similarity Heuristic for Novel Person Representations

Implicit measures have revealed that cognitive representations of familiar individuals share associations with self-concept; however, this has yet to be established for novel individuals. We examined how self-similarity affects representation of information learned about new individuals. A novel version of the implicit association test (IAT), the self-similarity IAT, was developed to estimate the extent to which cognitive representations of new self-similar and self-dissimilar individuals are associated with self-representation. Categorization was faster when the self-similar individual was paired with self, not only for trait words related to the novel individuals, but also for unrelated demographic information pertaining only to self. This provides the first evidence using an implicit task that self-similarity may act as a heuristic for creating representations of new individuals.     

自我-他人重叠及其相关概念辨析

在总结自我-他人重叠概念的提出历程、测量方法、结构, 以及常用改变方法的基础上, 通过辨析自我-他人重叠与关系自我、自我扩张之间的关系, 以及它和社会距离之间的异同, 明晰了自我-他人重叠的本质特点。自我-他人重叠是强调自己和他人具有相似表征的关系自我, 是个体在自我扩张动机的驱使下, 将他人的资源、观点和特质纳入自我的结果。未来可以借鉴关系自我神经机制的研究成果来探讨自我-他人重叠的神经机制, 还可以深入探讨过高的自我-他人重叠对亲密关系的消极作用。

Egocentrism versus protocentrism: the status of self in social prediction

In this article, the author discusses the limitations of the egocentric view of self in which self serves as an automatic filter, inhibiting access to alternative representations of others' thoughts and feelings. The author then outlines a protocentric model, the self-as-distinct (SAD) model, in which generic representations of prototypic others serve as the default; representations of self, specific others, or categories encode only distinctiveness from generic knowledge about prototypic others. Thus, self-knowledge is distributed both in generic representations in which self and prototypic others are undifferentiated and in a self-representation that encodes distinctiveness. The self-representation does not serve to make predictions about others because it encodes how self differs from the generic representation of others. Predictions that are the same about self and others are protocentric, based on generic knowledge that serves as the default. The SAD model parsimoniously accounts for many inconsistent findings across various domains in social cognition.     

Cultural Differences in the Self: From Philosophy to Psychology and Neuroscience

Different thinking styles in Westerners and Chinese (analytic vs. holistic) lead to disparities between the two cultures not only in perception and attention but also in high‐level social cognition such as self‐representation. Most Western philosophers discussed the self by focusing on personal self‐identity, whereas Chinese philosophers emphasized the relation between the self and others. Dissimilar philosophical thinking of the self is associated with distinct cognitive styles of self‐representation (i.e., the independent self in Westerners and the interdependent self in Chinese). Recent brain imaging studies found that Westerners employed the medial prefrontal cortex to represent only the individual self, whereas Chinese utilized the same brain area to represent both the self and close others, providing neural basis of cultural differences in self‐representation. We suggest that the cultural differences in thinking styles between Westerners and Chinese influence both psychological and neural structure of self‐representation.     

熟练潮-普双言者的语义通达机制:来自通道比较的证据

采用跨语言启动的范畴判断范式,通过2个实验,考察了熟练潮-普双言者在听觉通道内和听-视跨通道条件下的语义通达机制。结果发现,无论是以潮州话词语为启动词,还是以普通话词语为启动词,当词对具有高语义相关时,启动词均对目标词产生了显著的跨语言启动效应;在听觉通道内,两种语言之间的启动量无差异,而在听-视跨通道条件下,L2对L1的启动量显著大于L1对L2的启动量。这些结果表明,熟练潮-普双言者共享语义(概念)表征,词汇表征既相互独立又互相联系,L1与L2的词汇均能直接通达语义表征,但其联系强度及其相互之间的词汇表征联系强度均存在通道差异性。整个研究结果支持Kroll等人的修正分级模型。     

Measuring Parents’ Elaborative Reminiscing: Differential Links of Parents’ Elaboration to children’s Autobiographical Memory and Socioemotional Skills

ABSTRACT

Parents’ elaboration plays an important role in autobiographical memory and socioemotional development. Two types of coding approaches have been used to assess parents’ elaboration: a frequency-based coding (absolute frequencies of different types of elaborative utterances) and a scale-based coding (a 5-point scale based on relative frequencies of types of questions). We examined whether these two coding approaches were related and whether they were differentially associated with child autobiographical memory and socioemotional skills. Sixty-eight preschoolers (M = 50.32) reminisced about positive and negative past events, with their parents and with a researcher. Parents’ elaboration was assessed using the frequency- and scale-based coding approaches. Child autobiographical memory and emotion references were assessed in shared recall (parent–child conversations). Child autobiographical memory was also assessed in independent recall (researcher-child conversations). Child emotion regulation was assessed using the Challenging Situation task. The two coding approaches were moderately related. Parents’ elaboration was related to child autobiographical memory and emotion references in shared recall, regardless of the coding approach. Whereas the frequency-based coding was uniquely related to child memory in the independent recall, the scale-based coding was uniquely related to child emotion regulation. Implications of using diverse coding approaches to understand the role of parents in child development are discussed.     

Mutual influences between the implicit and explicit self-concepts: The role of memory activation and motivated reasoning

Whereas previous research has predominantly focused on dissociations between the explicit and implicit self-concepts, the current research investigates how these aspects of self-representation come into correspondence through the activation of information about the self in memory. Experiment 1 provides evidence for a “bottom-up” process of self-construal in which information activated in the implicit self-concept produces congruent changes in the explicit self-concept. Experiment 2 provides evidence for a “top-down” process of self-construal in which the motivated assertion of a propositional belief in the explicit self-concept leads, via a process of confirmatory hypothesis testing, to the activation of substantiating information in the implicit self-concept. These two processes of self-concept change are integrated within a framework that specifies how the explicit and implicit self-concepts are related within an overall, dynamic self-system. Possibilities for expanding the framework to account for self-concept dissociations are discussed.
