本研究采用"投注—反馈"的虚拟赌博游戏范式,通过2个实验分别检测个体在评价自己决策结果 (实验1)和观察他人决策结果 (实验2)过程中赌注大小(即参照点)对大脑活动的影响。结果发现:(1)体验自我决策结果时,输钱比赢钱诱发更负的FRN,仅有一个负反馈(-10元)表现出以赌注为界的分离,且相对效价一样的反馈值诱发的FRN差异不显著;(2)体验他人决策结果时,无论输赢,有赌注比无赌注诱发的FRN更负;而且相对效价相同的反馈值诱发的FRN差异不显著。据此可以认为,FRN一定程度上反映了以赌注为基准的主观标准对社会信息的评价判断:自我体验中的个体对损失的敏感度远高于收益;而替代体验中的个体更倾向于将"损失更多"看作一种负性结果。 相似文献

选取3063名大学二年级本科生(平均年龄19.76 ± 0.73岁)为被试,考察大学生投入在学习体验(课堂学习体验和课外学习体验)和学习结果(学业成就、共通能力和学习满意度)间的中介作用。结果发现:(1)大学生投入在学习体验和学业成就间起部分中介作用;(2)大学生投入在学习体验和共通能力间起完全中介作用;(3)大学生投入在学习体验和满意度间起部分中介作用。 相似文献

以往关于权力是否影响情绪的研究存在结果争议,这意味着可能存在其它因素的作用。本研究基于权力控制理论和社会距离理论,探究了社交情境中权力和反馈对情绪的影响。研究1采用经验取样法收集了140名被试五天内的1706段社交经历,研究2采用实验法考察了148名被试的社交经历。结果表明,权力和反馈对情绪存在交互影响:(1)当个体处于低权力情境时,反馈影响情绪,反馈越积极,情绪也越积极;(2)当个体获得积极反馈时,权力不影响情绪;当个体获得消极反馈时,权力影响情绪,权力越高,情绪相对更积极。本研究有助于厘清以往研究关于权力与情绪关系的争议。 相似文献

Two different ways of using the AHP in making group decisions are compared and evaluated. The first method combines different experts’ opinions before applying an eigenvalue method to obtain final weights for decision alternatives. The second, in contrast, derives each expert's rating for the decision alternatives before combining them. Both methods take into account the relative importance of different experts in making decisions. Comparison and evaluation of these two methods are made by using two criteria: time complexity and consistency indices. A numerical example is provided to illustrate the use of these two methods, and results of a mathematical simulation are presented for comparing the time complexity in different-sized problems. © 1998 John Wiley & Sons, Ltd. 相似文献

回报谨慎对谈判过程和谈判结果的影响 总被引:4,自引:0,他引:4
回报谨慎是人们害怕在人际关系中被他人利用的一种信念。研究考察了回报谨慎对谈判者的动机倾向、谈判行为及谈判结果的影响。184人组成92个两人小组参加了一项模拟商业谈判,谈判前研究者成功地进行了回报谨慎的操纵,谈判结束后,参加谈判的人完成谈判协议和谈判后问卷。研究者假设,低回报谨慎的谈判者比高回报谨慎的谈判者在谈判中更可能持有合作倾向、更多地与谈判对手分享信息,研究者还预测回报谨慎与谈判双方的联合收益以及谈判后对谈判对手的看法都有关系。研究结果支持了上述假设。研究对从事商业谈判的人具有实际意义。 相似文献

The vast amount of information that must be considered to solve inherently ill‐structured and complex strategic problems creates a need for tools to help decision makers (DMs) recognize the complexity of this process and develop a rational model for strategy evaluation. Over the last several decades, a philosophy and a body of intuitive and analytical methods have been developed to assist DMs in the evaluation of strategic alternatives. However, the intuitive methods lack a structured framework for the systematic evaluation of strategic alternatives while the analytical methods are not intended to capture intuitive preferences. Euclid is a simple and yet sophisticated multiobjective value analysis model that attempts to uncover some of the complexities inherent in the evaluation of strategic alternatives. The proposed model uses a series of intuitive and analytical methods including environmental scanning, the analytic hierarchy process (AHP), subjective probabilities, and the theory of displaced ideal, to plot strategic alternatives on a matrix based on their Euclidean distance from the ideal alternative. Euclid is further compared to the quantitative strategic planning matrix (QSPM) in a real world application. The information provided by the users shows that Euclid can significantly enhance decision quality and the DM's confidence. Euclid is not intended to replace the DMs, rather, it provides a systematic approach to support, supplement, and ensure the internal consistency of their judgments through a series of logically sound techniques.

This paper introduces a method for finding the non‐dominated set in criterion space of an MOLP problem based on Fourier–Motzkin Elimination. The method incorporates a procedure that eliminates decision variables from constraints and transforms a feasible region from decision space to criterion space. While avoiding characterization of the efficient set in decision space, it finds the non‐dominated set in criterion space. After the decision maker's most preferred criterion vector has been identified, the corresponding efficient solutions can be found by backward substitution. The method was implemented in MATLAB using a tabular form and computational experiments were conducted. The results indicate that although the method performs well for relatively small problems, it can be computationally intensive for larger problems. Nonetheless, the method is intuitively appealing and it provides useful insights into the geometry and theory of MOLP. As such it makes it a valuable educational tool for students of multi‐criteria decision analysis. Copyright © 2003 John Wiley & Sons, Ltd. 相似文献

An intermediate step is introduced to the dialogue decision process for decision analysis. Alternatives are refined after they have been generated within a strategy table but before they are subject to more detailed evaluation. Two or more judges create a subjective mapping from alternatives to attributes that will later be mapped to criteria. In strategy tables, each of the alternative strategies consists of a coherent set of choices made across several decisions that are to be coordinated. These strategic alternatives are modified so as to increase their differentiation in the attribute space, rather than in the decision space alone. When criteria weights are unknown, the best alternative from the modified set may be superior to the best alternative from the original set. Furthermore, analysis of the resulting alternatives may yield a better mapping of the value response surface for the action space, in the sense that this mapping leads to eventual construction of a higher value alternative. Results are reported for a consulting engagement incorporating the proposed step. Copyright © 2003 John Wiley & Sons, Ltd. 相似文献

在回顾自我建构理论发展脉络的基础之上, 介绍了特质性自我建构的测量和情境性自我建构的激活方法, 并从自我建构的性别与文化差异以及自我建构与认知风格、社会比较、人际交往、个人自主、自我调控的关系等几方面概述了该领域现状。该领域研究的进一步推进依赖于自我建构理论基本思想的完善、测查工具的改进以及研究者能否用辩证视角看待变量间关系。特质性自我建构对个体稳定的个性心理特征以及适应状况的影响, 特质性自我建构个体差异的影响因素应在未来研究中得到重视。 相似文献
