Social comparison processes in an organizational context: New directions

The goal of this article is to frame some new directions to social comparison research in organizational settings. Four themes are developed. First, we examine the role of organizational variables in shaping the basic sub processes in social comparison, such as the selection of referents. The second theme focuses on the meaning of level of analysis in social comparison processes. The third theme develops how time can enhance our understanding of social comparison. Lastly, we explore some methodological issues inherent in the three prior themes.     

Option fixation: A cognitive contributor to overconfidence

The ASC model of choice and confidence in general knowledge proposes that respondents first Assess the familiarity of presented options, and then use the high-familiarity option as a retrieval cue to Search memory for the purposes of Constructing an explanation about why that high-familiarity option is true. The ASC process implies that overconfidence results in part from a tendency to fixate on the high-familiarity option, to the neglect of the other option. If this implication is true, then judgment tasks requiring respondents to evaluate each option independently should result in reduced overconfidence as compared with standard judgment tasks. Two experiments tested this implication, and found that confidence and overconfidence were reduced when respondents evaluated options independently. The findings support the proposal that option fixation contributes to overconfidence, and also clarify the limitations of random error explanations of overconfidence.     

Regarding Scenes

ABSTRACT— When we view the visual world, our eyes flit from one location to another about three times each second. These frequent changes in gaze direction result from very fast saccadic eye movements. Useful visual information is acquired only during fixations, periods of relative gaze stability. Gaze control is defined as the process of directing fixation through a scene in real time in the service of ongoing perceptual, cognitive, and behavioral activity. This article discusses current approaches and new empirical findings that are allowing investigators to unravel how human gaze control operates during active real-world scene perception.     

Situated Social Cognition

ABSTRACT— Social cognition refers to the mental representations and processes that underlie social judgments and behavior—for example, the application of stereotypes to members of social groups. Theories of social cognition have generally assumed that mental representations are abstract and stable and that they are activated and applied by relatively automatic, context-independent processes. Recent evidence is inconsistent with these expectations, however. Social-cognitive processes have been shown to be adaptive to the perceiver's current social goals, communicative contexts, and bodily states. Although these findings can often be given ad hoc explanations within current conceptual frameworks, they invite a fuller integration with the broad intellectual movement emphasizing situated cognition. Such an approach has already been influential in many areas within psychology and beyond, and theories in the field of social cognition would benefit by taking advantage of its insights.     

不同问题情景对小学生运用乘法运算策略的影响

通过设置不同问题情景引导被试利用乘法运算定律解决数学问题,探讨不同问题情景对小学四、六年级学生运用乘法运算策略的影响。结果表明:(1)被试掌握交换律的情况均好于分配律;即使没有正式学过交换律,四年级被试使用交换律的成绩与六年级被试没有显著差异。(2)六年级被试在同形问题情景中利用分配律线索的成绩好于其它的问题情景,两个年级后进生同形问题的成绩均好于其它问题情景。总体而言,相对于面积问题情景和笛卡尔积问题情景,同形问题表征方式更有利于小学生利用乘法运算策略。     

Contrasting stochastic and support theory accounts of subadditivity

Numerous studies have found that likelihood judgment typically exhibits subadditivity in which judged probabilities of events are less than the sum of judged probabilities of constituent events. Whereas traditional accounts of subadditivity attribute this phenomenon to deterministic sources, this paper demonstrates both formally and empirically that subadditivity is systematically influenced by the stochastic variability of judged probabilities. First, making rather weak assumptions, we prove that regressive error (or variability) in mapping covert probability judgments to overt responses is sufficient to produce subadditive judgments. Experiments follow in which participants provided repeated probability estimates. The results support our model assumption that stochastic variability is regressive in probability estimation tasks and show the contribution of such variability to subadditivity. The theorems and the experiments focus on within-respondent variability, but most studies use between-respondent designs. Numerical simulations extend the work to contrast within- and between-respondent measures of subadditivity. Methodological implications of all the results are discussed, emphasizing the importance of taking stochastic variability into account when estimating the role of other factors (such as the availability bias) in producing subadditive judgments.     

整体语境和局部语境对代词理解的影响

通过眼动实验,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。实验一是预备实验,发现名词与动词词组之间关系的典型性不同,整合的速度也不一样。实验二发现,代词的理解不是一次完成的,代词理解的初期受整体语境的语义偏向影响,而不受局部语境的影响。在第二阶段主要受到局部语境的影响。代词的理解过程比较符合Cook（2004）所提出的两阶段模型     

大学生负面身体自我认知加工偏好

基于负面身体自我图式理论,采用词汇判断任务的实验范式,探讨负面身体自我者的认知加工偏好。研究1考察胖负面身体自我大学生对胖相关的身体信息词加工偏好,结果表明,加工胖身体相关词的编码速度比对照组显著更快,对胖消极和隐喻词偏好量大于积极词。研究2考察瘦负面身体自我大学生对瘦相关的身体信息词的加工偏好,发现对瘦相关词的编码速度显著比对照组更快,但对瘦积极词、消极词、隐喻词、形似词编码的偏好量不存在差异。结果支持负面身体自我图式指导认知加工     

学习判断及其准确性

学习判断是元认知判断的一种重要形式,是对未来记忆成绩的预测。产生机制及其准确性是学习判断研究的核心问题。研究者从不同的角度提出了多种理论,试图说明学习判断的机制与准确性。Koriat的线索模型总结了以往的研究发现,加深了人们对学习判断的理解,但该模型也面临着新的挑战。文章指出了已有研究中存在的问题及未来研究的方向。     

异同比较中的维度转移效应

以有颜色的实心几何图形为刺激材料进行了4个实验,考察异同比较中异反应之间的序列效应,被试为北京农业工程大学本科生77名。实验1a和1b中前后刺激对完全平衡,而实验2a和2b中前后刺激对随机平衡。实验1a,2a和2b发现了维度转移效应,表现为对于异反应后的异反应,前后2次异反应的差异维度一致时的反应快于不一致时的反应。本文以认知神经科学已有的相关证据解释了该效应产生的原因,并指出该效应反映了选择性注意在异反应判断中起重要作用,而且当任务要求注意在刺激维度上的分配不断变化时,注意按照当前刺激的特点做实时的分配
