本研究旨在考察情感启发式对风险选择的影响。研究1采用线上和线下结合的方式对687名大学生进行问卷施测,修订并检验中文版情感启发式问卷的信效度,以该问卷测试的风险−收益相关系数作为衡量情感启发式倾向的指标。研究2采用极端被试法,在103名大学生完成问卷后,将风险−收益相关系数绝对值前20%和后20%的被试分为高、低情感启发式组,完成风险选择任务。结果发现:(1)中文版情感启发式问卷具有较好的信度与效度,可以作为情感启发式倾向的测试问卷。(2)风险选择任务激活负性情绪时,相比于低情感启发式倾向,高情感启发式倾向的被试更容易受负性情绪的影响,其风险判断的主观值更高。研究揭示了情感启发式对风险选择的影响,为情感启发式作为个体进行风险判断的重要依据提供了实证支持。 相似文献

情绪对个体判断和决策影响研究概述 总被引:11,自引:0,他引:11
情绪对个体判断和决策影响已经成为目前的一个研究热点。情感启发式、决策情感理沦等为研究情绪对个体判断和决策的影响提供了一定的理论基础.而近期提出的“风险作为情感”假设为研究提供了较为全面的理沦框架。此外,个体差异比较、时间压力以及信息激起为研究情绪在个体判断和决策中的作用提供了很好的研究思路。 相似文献

该研究通过事件性质、重要程度和主体相关性对贝叶斯推算、判断的影响,探索了贝叶斯推理中的情绪启发式现象,结果表明:1)在贝叶斯推算中,事件重要程度不同,后验概率值的事件性质的主效应显著性不同,事件性质与主体相关性交互作用的显著性不同,但主体相关性的主效应均为不显著;2)在贝叶斯判断中,事件重要程度不同,事件性质和主体相关性在判断上的效果不同;3)在贝叶斯推理中,情绪启发式致使个体的推断结果具有某种系统化的倾向. 相似文献

采用问卷与实验相结合的方法,以120名大学生为被试,考察认知闭合需要与一般启发式策略对个体价格判断的潜在影响。结果发现:(1)认知闭合需要与精确度效应交互作用显著,高闭合个体在整数价格高低的评价上高于低闭合个体;(2)认知闭合需要与差价大小交互作用显著,差价整数位是3时高闭合个体对于差价的评价高于低闭合者;(3)认知闭合需要,左侧数字改变与以9结尾、以0结尾三者的交互作用显著,当评价左侧数字改变的价格时,高闭合个体对以0结尾的数字的评价显著高于以9结尾的数字的评价。认知闭合需要与启发式策略对价格判断共同产生影响。研究结果表明,不同的定价方式与定价策略会对认知闭合需要不同的个体产生差异性影响。 相似文献

关联启发式是指在累积变量判断中, 将存量与流量建立正相关关系, 认为存量变化特征与流量变化特征具有相似性而导致判断偏差的思维模式。在多特征交互及简单动态系统任务判断中, 关联启发式偏差以不同形式的S-F错误表现出来。作为一种内生性的、顽固的思维模式, 对于关联启发式的心理机制提出了客体偏差、特征替代、不充分调整等多种观点解释。影响关联启发式的个体因素和情境因素的研究结果不尽一致。由于关联启发式偏差直接影响人对复杂系统的可持续性决策和行动, 减少偏差策略的研究也已实现起步。本文系统总结和分析了关联启发式研究的发展脉络, 针对澄清关联启发式的发生机制、系统考察关联启发式的影响因素及其相互作用、丰富和深化关联启发式的研究范式、开发减少关联启发式的有效途径等方面, 提出了深化研究的方向和思路。 相似文献

Prior studies have observed that the attractiveness of playing a simple gamble (7/36 to win $9; otherwise win nothing) is greatly enhanced by introducing a small loss (7/36 win $9; otherwise lose 5¢). The present studies tested and confirmed an explanation of this finding based on the concept of evaluability and the affect heuristic. Evaluators of the “no‐loss” gamble lack a precise feeling for how good $9 is, hence give it little weight in their judgment. In the second gamble, comparison with the small loss makes $9 “come alive with feeling” and become weighted in the judgment, thus increasing the attractiveness of the gamble. These results demonstrate the importance of contextual factors in determining affect and preference for simple risk‐taking opportunities. They show that the meaning, utility, and weighting of even a very familiar monetary outcome such as $9 is not fixed, but depends greatly on these contextual factors.

When Is More Better? 总被引:2,自引:0,他引:2

Abstract— We examine three determinants of the relationship between the magnitude of a stimulus and a person's subjective "value" of that stimulus: the process by which value is assessed (either by feeling or by calculation), the evaluability of the relevant magnitude variable (whether the desirability of a given level of that variable can be evaluated independently), and the mode of evaluation (whether stimuli are encountered and evaluated jointly or separately). Reliance on feeling, lack of evaluability, and separate evaluation lead to insensitivity to magnitude. An analysis invoking these factors provides a novel account for why people typically become less sensitive to changes in the magnitude of a stimulus as magnitude increases. 相似文献

Risk Perception and Affect 总被引:4,自引:0,他引:4
ABSTRACT— Humans perceive and act on risk in two fundamental ways. Risk as feelings refers to individuals' instinctive and intuitive reactions to danger. Risk as analysis brings logic, reason, and scientific deliberation to bear on risk management. Reliance on risk as feelings is described as "the affect heuristic." This article traces the development of this heuristic and discusses some of the important ways that it impacts how people perceive and evaluate risk. 相似文献

ABSTRACT— The serotonin system is a collection of neural pathways whose overall level of functioning (from low to high) relates to diverse kinds of psychological and behavioral variability. Individual differences in serotonergic function are important both in personality and in vulnerability to psychological disorders. These disorders range widely—from impulsive aggression to depression. One way to understand such diverse reflections of differences in serotonergic function is by viewing serotonergic function through the lens of two-mode (or dual-process) models of self-regulation. Such theories posit a lower-order system that responds quickly to associative cues of the moment and a higher-order system that responds reflectively and planfully. Low serotonergic function appears to enhance influence of the lower-order system. This often yields impulsive reactivity. Why, then, does low serotonergic function also relate to depression, which is characterized by lethargy and unresponsiveness? The answer must be that ascendance of the lower system interacts with other factors. One hypothesis is that low serotonergic function plus high sensitivity to incentives yields vulnerability to impulsive approach, whereas low serotonergic function plus low incentive sensitivity yields vulnerability to depression. Conceptualizing serotonergic function this way helps integrate information pertaining to very different disorders into a coherent picture. 相似文献

时间与金钱是影响人们消费行为决策的两种不同的重要资源。消费者在进行产品购买时, 常常会受到商家广告语和购物环境中所隐含的时间或金钱概念的影响, 从而做出不同的决策。具体而言, 时间与金钱概念会对消费者的购前决策、购中决策及购后决策三个方面产生不同的影响。从双加工理论的角度来看, 产生这种不同影响背后的心理机制在于时间与金钱概念启动了个体不同的认知加工方式和思维定势, 进而影响了消费者不同的购买决策。未来的研究方向有:(1)细化时间和金钱概念启动对消费者购买决策的不同影响; (2)考虑时间与金钱的权衡对购买决策的影响; (3)进一步探究时间和金钱概念的激活对购前决策的不同影响; (4)探讨时间概念与金钱概念对购买决策不同影响的神经机制。 相似文献
