一拍即合：选择闭合影响最优化型决策风格者选择超载的中介机制

本研究通过3个研究探讨最优化型决策风格者更易选择超载的内在机制、以及如何缓解最优化型决策风格者选择超载。结果发现：(1)相较于满意型决策风格者,最优化型决策风格者更易选择超载;(2)选择闭合低是导致最优化型决策风格者选择超载的心理机制;(3)躯体闭合动作能够有效启动选择闭合感知,缓解最优化型决策风格者选择超载的负面作用。本研究对选择超载和最优化研究具有一定理论贡献,同时为消费者和商家提供实践启示。     

挑战性-阻碍性压力源、角色超载和情绪枯竭的关系:心理弹性的调节作用

结合工作要求-资源模型和资源保护理论,构建并检验了挑战性和阻碍性压力源与情绪枯竭之间关系的调节中介模型。结果表明,角色超载在挑战性压力源、阻碍性压力源和情绪枯竭之间起部分中介作用。心理弹性较低时,挑战性压力源会对情绪枯竭产生直接正向影响,角色超载在它们中间不起中介作用;阻碍性压力源既对情绪枯竭产生直接正向影响,也对情绪枯竭产生间接正向影响。心理弹性较高时,挑战性压力源对情绪枯竭的直接影响不再显著,而是通过角色超载对情绪枯竭产生正向影响;阻碍性压力源同样通过角色超载对情绪枯竭产生影响。心理弹性高和心理弹性低的个体相比,阻碍性压力源对情绪枯竭影响的差异性并不显著。     

Multiple-criteria decision aid: Some epistemological considerations

This paper attempts to analyse in a critical way some essential aspects of the multiple-criteria decision aid (MCDA) methodology using modern epistemological instruments. Particular attention is paid to the problem of information precision and uncertainty and to the distinction considered essential between the concepts of choice and decision. Since it is maintained that the respect of subjectivity in decision aid is of fundamental importance, an analysis follows of the main approaches by which MCDA methods attempt to take the subjective component of the decision maker into account, indicating some characteristics which may be desirable in an MCDA model for this purpose.     

Choice functions in multistage optimization

This paper is devoted to the multistage optimization problem with a vector-valued gain function. The notion of optimality is determined here by the choice function. The conditions for the choice function that guarantee the applicability and efficiency of dynamic programming are found.     

Same destination,different paths: When and how does observing others' choices and reasoning alter confidence in our own choices?

Seeing others make the same decision we do does not always increase choice confidence or tell the whole story of social influence when consumers expect to have to publically discuss their choice and reasoning. Instead, consumers' confidence in their publically stated choices can be diminished if observed others make the same choice but justify the choice using different reasoning. This effect occurs because confidence in one's own reasoning is thrown into doubt, rather than due to a desire to affiliate with the observed other. These effects are eliminated in both private choice contexts and in rejection versus selection tasks.
