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. 相似文献

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. 相似文献

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. 相似文献

Situated Social Cognition 总被引:2,自引:0,他引:2
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. 相似文献

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。 相似文献

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. 相似文献

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 相似文献

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 相似文献
