Tracking the identity of moving words: Stimulus complexity and familiarity affects tracking accuracy

In two experiments, participants tracked the identity and location of moving words. The task bears resemblance to one performed by air traffic controllers who track multiple moving aircraft, where they are identified with relatively complex alphanumeric call signs. In Experiment 1, stimulus familiarity was manipulated by comparing the tracking of familiar words and pseudowords. In Experiment 2, also stimulus complexity was varied by having the participants track short and long words. Stimulus complexity affected tracking: Short words were easier to track than long words. Moreover, familiarity of identity affected tracking of short words (short familiar words were easier to track than short pseudo-words) but not of long words. The results are interpreted within the framework of the model of multiple identity tracking model. Mathematical simulations suggest that observers may not have enough time for full identification of complex identities in a dynamic situation. Practical implications of the results for air traffic control are discussed.     

类别性空间记忆右侧化优势及其受威胁情境的影响

以往研究发现类别空间关系表征具有左半球激活优势,但在行为表现中是否存在对侧化的右侧化优势尚且不明确。本研究采用两个被试内实验,探讨空间记忆的行为表现是否具有右侧化优势以及这种优势是否受威胁情境的影响。实验1被试学习完一幅模拟地图中物体位置关系后进行相对位置判断任务,结果发现了显著的空间行为反应右侧化优势。实验2使被试在威胁情境中完成相同任务,发现右侧化优势消失。实验表明类别性空间记忆的行为表现具有右侧化优势,且具有情境不稳定性,这为空间记忆的偏侧化研究提供了一定的行为实验证据。     

情境模型中时间和空间维度更新的相互影响

运用移动窗口技术考察情境模型中时间和空间维度同时或序列转变时二者间的相互关系。结果发现：(1)时间和空间同时转变时, 二者存在易化关系, 但时间对空间的易化作用更大; (2)当二者序列转变时, 以中文为材料的结果只发现时间对空间的易化关系, 而以英语为材料的结果则发现存在双向易化关系, 但时间对空间的易化作用更大。据此, 情境模型中的时间和空间维度更新的捆绑－预期假设得到证明。     

Situational power moderates the influence of Self-Transcendence vs. Self-Enhancement values on behavior in ultimatum bargaining

We examined the interactive effects of personal values and situational power on proposer and responder behavior in an ultimatum bargaining game. The current literature suggests that situational power could moderate the influence of personal values on behavior. For proposers (N = 107), high scores on the Self-Transcendence vs. Self-Enhancement value dimension predicted higher proposals, but only among participants told that they were in a powerful position. For responders (N = 95), high scores on the Self-Transcendence vs. Self-Enhancement value dimension predicted accepting smaller proposals, but again only among participants told that they were in a powerful position. Our results support the idea that high situational power elicits behavior more consistent with one’s standing on the Self-Transcendence vs. Self-Enhancement value dimension.     

Helplessness and the exercise of power in the analytic session

This paper describes a clinical situation in which the analyst may be provoked to become overactive if he feels that his attempts to reach his patient are frustrated. Lack of tolerance for feelings of helplessness may leave him unable to sustain a receptive stance, and he may be drawn into enactments which lead to a power struggle with his patient.
I will try to describe situations where such enactments were compelling. I will also consider what enabled me to extricate myself from the activity, at least intermittently, to re‐establish an analytic attitude in which understanding and containment were priorities.
From time to time I was able to recognize and accept my helplessness and relinquish my attempts to reach the patient. These moments of recognition led to a shift of atmosphere in which a feeling of sadness replaced the more familiar confrontational mood. In these sadder moods the patient felt I was more available, and he too seemed more able to contemplate loss.
Theoretical ideas that enabled me to recognize some of the mechanisms at play included an understanding of narcissistic mechanisms, a recognition of previous ideas of power and dominance such as Freud’s Bemächtigungstrieb, and the role of dominance in the resolution of the Oedipus complex. My previous work on the dread of humiliation allowed me to be sensitive to the way helplessness can come to be associated with being looked down on and humiliated.     

自我解释的研究现状与展望

自我解释(self-explanation)是指学习者在学习过程中通过自己向自己解释学习内容而获得知识的过程。文章主要阐述了自我解释的含义、分类、三种自我解释效果的认知机制,并且提出自我解释研究中尚待解决的问题及对其进行展望。     

肺结核患者的血糖控制

肺结核与糖尿病是两种严重危害人类健康的疾病。越来越多的研究证明,发生结核病的一个重要的危险因素为糖尿病,而且可能会影响肺结核患者的表现和治疗反应。另外,结核病可能会导致糖耐量异常,并使糖尿病患者的血糖控制不良。糖尿病引起肺结核发病增加,可能是因为持续的高血糖损害了针对结核杆菌的机体免疫。对结核病患者合并糖尿病者,药物治疗需考虑到药物动力学,监测血糖,谨慎用药。     

人际吸引机制探索:主我分享中情绪的作用

研究以计算机仿真交流平台为工具,采用模拟情景方法,探讨了人际互动中相似性对人际吸引的影响和人际吸引机制。采用2×2组间设计,共32名被试。结果显示:(1)主我分享是态度相似的重要组成部分;(2)在人际交流与互动中,主我分享是影响人际吸引的重要因素;(3)情绪是主我分享影响人际吸引的中介变量,起部分中介作用;(4)人际互动情境模拟是研究人际交往的一种有效途径。     

The Logic of Causal Explanation An Axiomatization

Three-valued (strong-Kleene) modal logic provides the foundation for a new approach to formalizing causal explanation as a relation between partial situations. The approach makes fine-grained distinctions between aspects of events, even between aspects that are equivalent in classical logic. The framework can accommodate a variety of ontologies concerning the relata of causal explanation. I argue, however, for a tripartite ontology of objects corresponding to sentential nominals: facts, tropes (or facta or states of affairs), and situations (or events). I axiomatize the relations and use canonical models to demonstrate completeness.     

风险情景中参照点与管理者认知特征

采用问卷测量的方法探讨风险情景以及个性特征对个体风险倾向的影响。结果显示：(1)成就动机的两个成分,即争取成功与回避失败能够分别预测个体在风险情景中的风险倾向与认知特征;争取成功动机对预测个体机会认知更敏感,而回避失败动机对预测威胁认知更有效。(2)回避失败动机是区分个体风险倾向的关键变量,个体在风险情景中的风险倾向取决于个体回避失败动机的强弱。(3)实验证实了当以“成功”为参照点时,回避失败倾向低的个体,在获益情景中更冒险而在损失情景中更保守;相反,回避失败倾向高的个体,在损失情景中更冒险而在获益情景中更保守。研究表明,结合人格和情景两类变量探讨个体风险倾向的反应模式能够更准确地描述个体行为倾向及其认知特征。这一结论提供了一个可能的思路来解释P理论与刻板模式之间的争执。另外,企业与学生样本在数据的总体趋势上存在相当多的一致性,但在细节上仍然存在差异,因此以学生样本数据进行推论时须要特别谨慎。
