具体情绪与人格特质对决策信息加工过程的影响

研究选取120名大学生,探讨了具体情绪与人格特质对平均决策时间、决策的信息搜索深度和决策的信息搜索模式的影响。结果发现:(1)在平均决策时间上,具体情绪与人格特质主效应显著,并且交互影响决策的信息加工过程。在悲伤情绪下,内控型比外控型人格的个体平均决策时间要长。内控型个体在悲伤情绪比高兴情绪状态下平均决策时间长。(2)在决策信息搜索深度上,具体情绪与人格特质主效应显著,并且交互影响决策的信息加工过程。在悲伤情绪下,内控型比外控型人格的个体信息搜索深度要深。内控型个体在悲伤情绪比高兴情绪状态下信息搜索深度要深。(3)在决策信息搜索模式上,具体情绪与人格特质主效应显著,但两者交互作用不显著。内控型比外控型人格特质的被试在悲伤状态下更倾向于基于选项加工,内控型个体在悲伤状态比在高兴状态下也倾向于选项加工,而外控型个体在高兴情绪状态比在悲伤情绪状态下更倾向于线索加工。     

情绪调节策略对日常生活事件与情绪体验关系影响的多层分析

运用经验抽样法对154名大学生的日常情绪体验、生活事件进行为期14天的追踪调查,通过多层线性模型（HLM）探讨日常生活事件与情绪体验的关系及情绪调节策略对二者关系的影响。结果表明：大学生积极情绪体验多于消极情绪体验。在个体内和个体间水平,消极事件都对积极情绪有显著的负向预测作用,对消极情绪有显著的正向预测作用;积极事件对积极情绪有显著的正向预测作用。积极事件对消极情绪的负向预测作用只在个体间水平显著。表达抑制这种情绪调节策略能够增强消极生活事件与消极情绪体验的关系。     

情绪效价和动机情绪对创造力的影响

以图片材料为情绪启动刺激,以多用途测验(AUT)为创造力测量工具,探究情绪与创造力的关系。采用2(情绪效价类型:积极、消极)×2(动机情绪类型:高生存动机、低生存动机)的被试间设计,结果表明:情绪效价主效应显著,积极情绪组的创造力流畅性、灵活性、新颖性及总分显著高于消极情绪组;动机情绪主效应显著,低生存动机情绪组的创造力流畅性、灵活性及总分显著高于高生存动机情绪组;情绪效价和动机情绪的交互作用不显著。研究表明,积极情绪比消极情绪引发更多的创造性活动;低生存动机情绪下的创造力水平高于高生存动机情绪下的创造力水平;情绪效价与动机情绪对创造力的影响不存在交互作用。     

积极情绪的概念、功能与意义

积极情绪是指个体由于体内外刺激、事件满足个体需要而产生的伴有愉悦感受的情绪。积极情绪能够激活一般的行动倾向,对于认知具有启动和扩展效应,能够建设个体的资源,撤销消极情绪产生的激活水平,能够促进组织绩效。积极情绪是心理健康的重要组成部分,同时对身体健康具有促进作用。积极情绪对于个体的适应具有广泛的功能与意义     

情绪的确定性评价对信息加工的影响

检验了情绪的效价和确定性评价对个体的信息加工策略选择的影响及其心理机制。结果表明,情绪效价对个体的信息加工方式的影响会受到情绪确定性评价的调节。高确定评价的情绪中,积极情绪的被试更倾向于采用启发式加工,消极情绪的被试更倾向于采用系统式加工。积极情绪中,高确定评价情绪的被试更倾向于采用启发式加工,低确定评价情绪的被试更倾向于采用系统式加工。当个体对自己产生情绪的原因进行合理归因后,情绪效价和确定性评价对个体信息加工方式的影响效应都消失了,说明情绪的效价和确定性评价均以信息的方式对对个体信息加工策略的选择产生影响。     

任务无关积极情绪与时间限制对大学生风险决策的影响

利用日常生活决策任务,探讨了任务无关积极情绪和预支情绪与时间限制对风险决策的交互影响.研究结果表明:对于强调损失可能且意义重大的职业决策,积极情绪使个体表现出风险回避倾向,而时间限制通过影响个体的决策策略增强情绪状态对决策的影响作用.在无重大意义无损失可能的决策情境中,时间限制能降低个体的冒险倾向,而积极情绪通过促使个体夸大时间限制造成的压力,增强时间限制对风险决策的影响.     

情绪效价对不同抑郁水平大学生的反应性控制和主动性控制的影响

探讨情绪效价和抑郁水平对反应性控制和主动性控制的影响。通过国际情绪图片诱发出积极、中性和消极情绪,采用修订后的AX-CPT任务分离出两种认知控制,考察了不同抑郁水平大学生在认知控制上的差异。结果表明大学生更倾向于采用主动性控制;相比于低抑郁个体,高抑郁个体的主动性和反应性控制均有下降;相比消极情绪,积极情绪可以降低高、低抑郁个体的主动性控制,但积极情绪只能降低高抑郁个体的反应性控制,对低抑郁个体无影响。     

情绪对职业决策的影响

职业决策是决策研究领域的重要课题,引起了心理学家和决策研究者的高度关注.本文在以往研究的基础上,引人情绪和职业种类变量探讨了情绪对职业决策的影响,结果显示:(1)无论是四种还是八种职业决策任务,积极情绪的被试同消极情绪的被试相比,信息搜索的时间较长,信息搜索的深度显著增加;(2)在职业选择策略上,积极情绪的被试更加倾向于基于选项的加工,而消极情绪的被试随着从四种职业决策任务到八种决策任务的转变,逐渐倾向于基于属性的加工;(3)情绪影响了决策者职业决策的信息加工能力.     

情绪对成就动机与风险决策关系的调节效应

本研究在验证成就动机对风险决策倾向的预测作用的基础上,进一步探索情绪在成就动机和风险决策关系中的调节效应。通过对三所学校随机抽取的150名被试进行筛选,采用成就动机量表和自编风险决策任务问卷等对120名有效被试实施问卷调查。结果发现：情绪启动使大学生风险决策行为产生一致性效应,即心境一致性;情绪在成就动机和风险决策中起到了一定的调节作用,无论是高成就动机者还是低成就动机者,在愉悦情绪下都表现出更多的风险寻求倾向,并达到了极其显著的水平,而在悲伤情绪下,低成就动机者表现出更多的风险规避,高成就动机者的风险规避倾向虽有所增加,但并未达到显著水平。     

线索—提示任务下情绪对注意转换的影响

大量研究表明情绪状态会影响认知灵活性。本研究运用情绪影片片段作为情绪诱发的手段,以68名女大学生为被试,采用线索-提示任务范式考察了不同情绪效价(积极、消极)对认知灵活性重要成分之一注意定向转换的影响。结果发现,对于有效提示,积极情绪和消极情绪两种条件下的反应时差异不显著;对于无效提示,积极情绪下的反应时显著快于消极情绪;而且,积极情绪下的线索有效性效应不显著,但消极情绪下表现出显著的线索有效性效应。实验结果说明,积极情绪有助于注意定向的转换,消极情绪延缓了注意定向的转换。这一结果进一步支持了积极情绪扩展认知范围,而消极情绪缩窄认知范围的观点。     

情绪对延迟折扣的影响：现状、机制与展望

延迟折扣研究领域日益重视情绪的影响作用。本文基于三类研究取向对情绪与延迟折扣关系研究进行了回顾。情绪效价和唤醒度均影响延迟折扣,但是研究结果并不一致;具体情绪类型不同,其对延迟折扣影响也存在差异。除此之外,本文就情绪信息理论、情绪动机维度理论和评估倾向理论如何解释延迟折扣进行了详细阐述。未来的研究需要进一步深入考察情绪影响延迟折扣的认知神经机制,从而为延迟折扣的负性情绪效应的干预提供可靠的科学依据。     

情绪状态对大学生条件推理的影响

采用不同情绪效价的电影片断诱发大学生不同的情绪,并运用眼动仪器记录条件推理的过程和结果,探讨了不同情绪状态对条件推理的影响状况。实验采用3（情绪组别：积极情绪、消极情绪、中性情绪）×4（推理形式：MP、DA、AC、MT）的混合实验设计。研究结果发现,中性情绪状态下的条件推理成绩显著地高于积极和消极情绪状态,结果支持抑制假说。     

Guilt and focusing in decision-making

In this paper we examined the impact of a specific emotion, guilt, on focusing in decision-making. Through the focusing mechanism, when making decisions, individuals tend to restrict their thoughts to what is explicitly represented in the decisional task, disregarding alternatives. In this paper, three experiments are performed to investigate whether an emotional state of guilt can critically guide individuals' focusing, and even prevailing over the focusing mechanism. Guilty emotional state was induced by asking participants to write about a guilty related life event. The emotional state was thus neither generated by nor related to the tasks used in the experiments. Results of the first two studies show that guilt affects focusing in decision-making in the case of only one explicitly specified option (a positive or a negative one). Guilty participants, when presented with a stated option that has predominantly positive characteristics, prefer other, unspecified options over the positive one. Guilty participants faced with a stated option that has predominantly negative features tend to prefer it to other, unspecified, options, instead. Finally, experiment 3 shows that guilty participants presented with two different options (a negative vs. a positive one) having different degrees of explicitness (i.e. they are not equally represented in the decision frame), focus on the negative option, even though the latter was not explicitly represented but only hinted at the end of the text. Overall, these results suggest that guilt emotion state can play a crucial role in either strengthening or reducing the focusing mechanism. Copyright © 2006 John Wiley & Sons, Ltd.     

特质焦虑初中生使用减弱调节策略的效果:一项ERP研究

采用情绪反应性-调节图片任务，考察特质焦虑青少年在下调负性情绪反应时的神经生理变化。结果发现，从行为学数据上看，两组被试都能达到下调目标，但低特质焦虑组的调节能力较强。从脑电数据上看，在刺激呈现之后300-600ms，高特质焦虑被试在负性情绪减弱调节效应方面显著小于低特质焦虑被试。在600-1000ms，高特质焦虑被试产生的LPP显著大于低特质焦虑被试。在1000ms以后，两组被试不存在显著差异。这就表明，我国高特质焦虑青少年对情绪反应有意调节能力总体较好，但较低特质焦虑青少年而言可能存在一定滞后性。     

Emotional processes in risky and multiattribute health decisions

Objective: Here, we develop an integrative account of the roles of emotion in decision-making. In Part I, we illustrate how emotional inputs into decisions may rely on physiological signals from emotions experienced while making the decision, and we review evidence suggesting that the failure to represent the emotional meaning of options can often reduce decision quality. We propose that health-related decrements in the ability to generate emotional reactions lead people to inaccurately represent emotional responses and compromise decisions, particularly about risk. Part II explores complex decisions in which choice options involve trade-offs between positive and negative attributes. We first review evidence showing that difficult trade-off decisions generate negative affect and physiological arousal. Next, we propose that medical decision-making will be linked to short- and long-term stress and health outcomes.

Conclusion: In sum, this article proposes and reviews initial evidence supporting the effective use and management of emotional inputs as important to both clinical and non-clinical populations. Our approach will contribute to the understanding of patient-centred emotional decision-making and will inform medical decision aids.     

Sadder but wiser or happier and smarter? A demonstration of judgment and decision making

Researchers have debated whether positive or negative emotions will positively improve decision performance (B. Kuvaas & G. Kaufmann, 2004). The author explored (a) which coping strategies decision makers use when they experience positive or negative emotions and (b) how cognitive processes are influenced by negative and positive emotions. In Experiment 1, participants (N = 120) in positive emotional states (i.e., happier and smarter) were better at problem-focused coping than were participants with negative emotions (i.e., sadder but wiser). In Experiment 2, participants (N = 124) displayed greater accuracy of choice, took longer to research information, and processed a larger amount of information when they were in positive emotional states. The two experiments showed similar results between judgment and decision-making contexts in which positive emotion enhances problem solving.     

The moderating role of emotional differentiation on satiation

People tend to like experiences less the more they repeat them, a process commonly referred to as satiation. Despite an increasing interest in satiation among consumer researchers, we still know very little about the role that emotions play in the process. Through a series of three experiments, we show paradoxically that when individuals differentiate between the positive and negative emotions that arise during repeated consumption, they satiate at a slower rate. We show that a cognitive re‐appraisal process drives this emotional differentiation effect, whereby, when individuals focus on negative emotions they exhibit increased enjoyment of repeated consumption sequences. We demonstrate these effects for both trait and state emotional differentiation and across both continued and repeated consumption contexts. Theoretical implications of these findings for satiation, emotional differentiation, and emotion regulation literatures are then discussed.     

亲社会情境中小学儿童道德情绪判断及其归因研究

该文运用临床访谈法研究了小学儿童在亲社会情境中道德情绪判断及归因状况。结果表明:在亲社会情境中,儿童的道德情绪判断经由消极到积极的发展趋势,年幼儿童倾向于判断助人者会体验到消极的情绪,年长儿童则认为助人者会体验到高兴等积极情绪,并且随着儿童年龄的增长,儿童的情绪体验愈加复杂。在道德情绪归因中,年幼儿童倾向于结果定向的归因,一年级儿童中大部分以道德定向为主,随着儿童年龄的增长,儿童的归因定向逐渐多样化。     

偶然情绪对延迟选择的影响机制

本研究旨在探讨偶然情绪对延迟选择的影响及影响机制。本研究包括两个实验, 在被试进行决策前, 分别采用图片和短片诱发其与当前决策任务无关的偶然情绪, 然后要求被试完成选择任务, 并从决策结果和决策过程两个角度考察偶然情绪对延迟选择的影响及影响机制。结果发现, 当可选项中不存在1个优势选项时, 与正性情绪相比, 个体在负性情绪下会更倾向于延迟选择, 而个体对决策信息的加工深度在偶然情绪对延迟选择的影响中具有中介作用。这可能是因为相比于正性情绪, 个体在负性情绪下会采用更深入的加工策略, 增加了决策难度, 进而提高了个体的延迟选择倾向。
