We present a generalization of a class of sequential search problems with ordinal ranks, referred to as “secretary” problems, in which applicants are characterized by multiple attributes. We then present a procedure for numerically computing the optimal search policy and test it in two experiments with incentive-compatible payoffs. With payoffs dependent on the absolute ranks of the attributes, we test the optimal search model with both symmetric (Experiment 1) and asymmetric (Experiment 2) search problems. In both experiments we find that, relative to the optimal search policy, subjects stop the search too early. Our results show that this bias is largely driven by a propensity to stop prematurely on applicants of intermediate (relative) quality. 相似文献

Abstract. Instead of focusing my remarks on John Caiazza's interesting and important thesis about the way in which modern technology is drastically secularizing our culture today, I examine the frame within which he sets out his thesis, a frame I regard as seriously flawed. Caiazza's argument is concerned with the broad range of religion/science/technology issues in today's world, but the only religion that he seems to take seriously is what he calls “revealed religion” (Christianity). His consideration of religion is thus narrow and cramped, and this makes it difficult to assess properly the significance of what he calls techno‐secularism. I suggest that employing a broader conception of religion would enable us to see more clearly what is really at stake in the rise of techno‐secularism. Instead of defining the issues in the polarizing terms of revealed religion versus secularity, I argue for a more integrative approach in which concepts are developed that can bring together and hold together major religious insights and themes with modern scientific thinking. If, for example, we give up the anthropomorphism of the traditional idea of God as creator and think of God as simply creativity, it becomes possible to integrate theological insights with current scientific thinking and to formulate the issues posed by the rise of techno‐secularism in a more illuminating way. This in turn should facilitate effective address of those issues. 相似文献

This study examined the extent to which patterns of involvement in interpersonal cognitive problem solving (ICPS) groups were predictive of improvements in ICPS skills. Thirty-one 7–8-year-old children were assigned to experimental or control groups. Participants in the experimental group participated in six sessions of ICPS group work. All participants were tested for the ICPS skills of alternative solutions thinking (AST) and consequential thinking (CT) immediately before and after the group work period. As predicted, the experimental group showed significantly greater improvements in AST and CT skills than the control group. Means-end thinking was significantly correlated with improvements in AST and CT, level of involvement and positive behaviour within the groups were predictive of improvements in AST but not CT. Findings indicated the importance of group dynamics for ICPS outcomes and are discussed in relation to their theoretical and practical implications. 相似文献

The author postulates that the dialogue between psychoanalysis and neuroscience is based on the assumption that both deal with virtual structures. They are two facets of the same noumenal reality, but with different phenomenal realities, and it is possible to use metapsychology as a lingua franca to develop communication between the two fi elds. In the second part of the paper, the author refl ects on the results of recent neurophysiological research which seem to offer to psychoanalysis possibilities for fi nding an anatomical‐physiological correlate of some well‐known psychic phenomena and mechanisms, such as imitation, introjection, identifi cation, empathy, identity, mother‐child communication, learning, social communication and the analyst‐patient relationship. Particular neurons, called mirror neurons, have been located in the F5 area of baboons' brains. They are also present in man's brain within Broca's area. These neurons activate our motor system during both the performance of actions and the observation of actions performed by others giving rise to an automatic response, a sort of simulation or, rather, imitation, as the process is not intentional, but automatic and unaware, that is, unconscious. 相似文献

复杂问题解决:探索人们如何控制复杂动态系统 总被引:1,自引:0,他引:1
复杂问题解决研究的目的是探索人们如何处理复杂、动态任务。Dorner作为该领域的先驱,将计算机模拟情境作为研究工具,后来的研究者从不同的角度进行复杂问题解决研究。本文介绍了复杂问题解决研究的发展历史,总结了复杂问题解决情境的特征,包括动态性、复杂性、模糊性以及时间滞后性,进一步比较了复杂问题解决与自然决策和动态决策的差别。在此基础上,从控制系统的个体要求以及系统特征等方面总结了在Dorner的个体差异比较范式下复杂问题解决研究的进展。最后提出复杂问题解决研究的展望。 相似文献

问题学生内隐自尊的初步研究 总被引:12,自引:3,他引:9
研究结果表明:(1)问题学生和普通学生一样,存在显著的内隐自尊效应。两类学生的内隐自尊效应存在显著的年级差异,但不存在性别差异;(2)总体上问题学生的内隐自尊效应显著高于普通学生,初三阶段,两类学生的内隐自尊的差异显著;(3)问题学生的内隐自尊和外显自尊是相对独立的两个自我评价系统。两类学生内隐自尊和外显自尊的组合状况不同,内隐自尊和外显自尊的分离状况差异显著;(4)问题学生内隐自尊与外显自尊的分离程度与其状态焦虑、特质焦虑和心理健康其他指标存在非常显著相关。 相似文献

在潜藏式与矛盾式情境两类问题发现任务中,采用出声思维的方法研究问题发现能力高与低两类各10名大学生问题发现过程的内部认知活动。利用问题行为图技术进行个案分析,着重考察大学生在知识状态、思维操作及问题行为图等方面的表现。基于加工性质把知识编码为陈述性、程序性和策略性知识;基于信息来源编码为情境、内部和推断信息;基于思维关联与转换,把思维操作编码为独立、横向、纵向与元认知思维。研究表明:(1)问题发现中,在内部信息、纵向思维以及纵横交错型行为图的使用频次上,潜藏情境高于矛盾情境;在情境信息、横向思维以及横向平行和横向归纳型行为图的使用频次上,矛盾情境高于潜藏情境。(2)高低能力组被试在知识状态、思维操作与问题行为图的使用上差异均不显著,可能是由于上述方面涉及问题发现的基本认知过程和思维规律,具有普遍性特征。 相似文献
