不同情感强度正性生活事件的情感和行为反应:多模型的检验和整合

3个实验探讨情感强度不同正性生活事件对个体情感和行为反应的影响。发现:(1)面对复合正性生活事件(1高正+1低正),个体会感觉比面对1个单独的高正性情感强度事件的正性感受更低,出现平均效应,2个正性生活事件不如1个好;进一步研究发现:(2)当复合正性生活事件为异类时,出现平均效应;当事件为同类时,出现累加效应;(3)当复合正性生活事件有明显的时间特点时,个体加工符合峰-终定律的解释。     

情感启发式对风险选择的影响

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。     

青少年负性情绪事件性质判断偏向的情绪弹性和性别效应

研究以青少年学生为被试,采用测验和实验的方法考察了情绪弹性和性别变量对青少年在四类负性情绪事件性质的判断偏向上可能产生的影响。结果表明：（1）情绪弹性对青少年加工负性情绪事件信息时的判断偏向产生一定影响,低情绪弹性个体在面对与一般生活情境相关的负性情绪事件时,更倾向于从消极方面对事件的性质加以判断。（2）性别对青少年加工负性情绪事件信息时的判断偏向不产生实质性影响。     

共患难,更同盟:共同经历相同负性情绪事件促进合作行为

4项实验探讨了共同经历相同负性情绪事件,相比单独经历负性情绪事件,是否以及如何促进了个体间的合作。实验1~3分别采用抽奖任务和瑞文推理测验任务操纵负性情绪事件,采用公共物品博弈任务测量合作行为,结果表明,共同经历相同负性情绪事件,相比单独经历负性情绪事件,促进了个体间的合作行为。实验2通过测量归属需要、社会联结和内群体认同,实验3通过操纵归属需要,来考察共同经历相同负性情绪事件促进合作行为的潜在机制,结果表明,共同经历者之间的合作行为受归属需要的驱动,而社会联结和内群体认同不足以对该现象进行解释。实验4通过操纵个体共同经历“相同”和“不同”的负性情绪事件,进一步厘清了,促进个体间的合作是由于“共同经历相同的负性情绪事件”而非“共同经历负性情绪”造成的。研究结果有利于解释小群体的形成,对群体和社会管理亦具有借鉴意义。     

自尊对情绪面孔注意偏向的影响

研究表明低自尊个体对负性信息表现出高度的警觉和关注,而高自尊个体相对来说注意积极地方面,但并未表现明显偏向。为了精确记录注意选择神经加工时间进程,进一步从电生理学角度对低自尊个体的负性注意偏向进行探讨,本研究运用事件相关电位（ERP）技术对不同自尊个体在点-探测任务过程中的注意偏向进行研究。实验一以129名在校大学生作为被试,以大学生面孔情绪图片（高兴、悲伤和中性）作为实验材料,结果发现,高低自尊个体之间没有出现注意偏向的差异。实验二以实验一筛选出的30名高低自尊个体作为被试,选择了更具负性情绪唤醒的愤怒图片作为实验材料（高兴、愤怒和中性）,行为数据结果发现,两组被试都没有出现注意偏向,相反,无论是在高兴面孔条件下还是在愤怒面孔条件下,低自尊个体的反应时都快于高自尊个体;电生理学数据结果发现,在低自尊个体中,在两种情绪面孔条件下,有效线索的P1峰值显著高于无效线索,而无效线索的N2pc峰值显著高于有效线索。电生理学数据表明,无论是负性的还是正性的情绪性的信息都能引起低自尊个体的更多注意,表明低自尊个体更容易受到情绪性信息的影响。     

知觉负载对负性分心面孔的知觉加工和记忆的影响

本研究采用视觉搜索和意外再认记忆任务,结合事件相关电位技术,考察知觉负载对负性分心面孔的知觉加工和记忆的影响。在视觉搜索任务中,行为上恐惧分心面孔在高负载下干扰任务。ERP结果上,恐惧比中性分心面孔诱发更大的N170和N250;在低负载下恐惧比中性分心面孔诱发更大的N700,在高负载下没有差异。在意外再认记忆中,个体对低负载下的恐惧分心面孔表现出记忆。这些结果说明负性分心物在早期是自动化加工;晚期加工受知觉负载的调节,负载越低对负性分心物的过滤越少,存在对负性分心物的记忆偏向。     

奖赏预期对面孔情绪加工的影响：一项事件相关电位研究

采用事件相关电位(ERPs)技术考察了奖赏预期对人类面孔情绪识别的影响。实验采用线索-目标范式, 分别记录了被试在奖赏预期条件下以及无奖赏预期条件下对正性、中性和负性面孔进行情绪辨别任务的ERP数据。行为结果显示, 被试在奖赏预期条件下的反应时快于无奖赏预期条件下的反应时, 对情绪面孔的反应时快于对中性面孔的反应时。ERPs数据显示, 奖赏线索比无奖赏线索诱发了更正的P1、P2和P300成分。目标刺激诱发的P1、N170波幅以及N300均受到奖赏预期的调节, 在奖赏预期条件下目标诱发了更正的ERPs。P1、N170、VPP等成分没有受到面孔情绪的影响, 而额中央位置的N300波幅显示情绪(正性与负性)面孔与中性面孔加工的差异。重要的是, N300波幅出现奖赏预期与情绪的交互作用, 正、负情绪加工效应以及负性偏向效应受奖赏预期的差异性影响。正性情绪加工效应不受奖赏预期的影响, 而负性情绪加工效应和负性偏向效应在奖赏预期条件下显著大于无奖赏预期条件下。这些结果说明, 奖赏预期能够调节对面孔情绪的加工, 且不同加工进程中奖赏对情绪加工的调节作用不同。动机性信息调节注意资源的分配, 促进了个体在加工面孔情绪时的负性偏向。     

记忆编码与特异性效应之间关系的ERP研究

通过事件相关电位（ERPs）探讨了在“学习–再认”模式条件下的记忆编码与特异性效应之间的关系。选择首要特异性特征为深、浅加工,次要特异性特征为高、低词频。研究结果表明,（1）行为数据支持了低频词的再认比高频词更精确;深加工的再认比浅加工更精确,并且深加工存在着显著的字频效应,浅加工没有显著的字频效应。（2）低频词比高频词有更大的ERP晚正成分（LPC）;在低频词条件下,存在着显著的相继记忆效应,随后再认正确的ERPs比随后再认不正确的ERPs更正。因此,加工方式和词频间接地影响着记忆编码的形成。     

非任务相关条件下社会权力对愤怒表情加工的影响

之前的研究表明权力能够影响愤怒表情的加工，但是并不清楚当愤怒刺激是非目标任务刺激时(非任务相关条件下)，权力是否影响以及如何影响愤怒表情的加工。本研究采用事件相关电位技术，首先操纵情绪观察者（被试）和情绪表达者（目标）的权力水平（高VS 低），之后采用修正的oddball范式考察当愤怒刺激是非目标任务刺激时，情绪观察者和表达者的权力水平对愤怒情绪加工的影响。行为结果表明，与高权力个体相比，低权力个体在识别年老面孔目标时成绩更低。脑电结果发现，与高权力个体相比，低权力个体对中性目标刺激和愤怒的非目标刺激均产生了更强的N170波幅，表现出更强的敏感性。该研究结果说明，高权力个体的行为成绩优于低权力个体的行为成绩，即使在非任务相关条件下，与高权力个体相比，低权力个体对愤怒情绪刺激的早期敏感性仍然更强。     

负性生活事件对初中生自我伤害行为的影响:有调节的中介效应

采用负性生活事件量表、自我批评量表、亲子关系量表和青少年自我伤害行为问卷对333名初中生进行测查,探讨负性生活事件对初中生自我伤害行为的影响及作用机制。结果表明:(1)负性生活事件对初中生的自我批评和自我伤害行为均有显著的正向预测作用;(2)自我批评在负性生活事件与初中生自我伤害行为之间起着部分中介作用;(3)负性生活事件和自我批评的关系(中介效应的前半段路径)受到亲子关系的调节,即负性生活事件对自我批评的正向影响随着父子关系和母子关系的增强而减弱。因此,负性生活事件和初中生自我伤害行为之间存在有调节的中介效应。     

Averaging and summation: Positivity and choice as a function of the number and affective intensity of life events

Six experiments were reported that investigated individuals’ perceptions of positive life events and their preferences for options presenting different combinations of positive event frequency and magnitude. Results revealed that individuals often responded to the average level of positivity and preferred less (versus more) positive events and supported the averaging/summation model of life event integration. Results revealed, for example, that participants felt more positive affect when they were exposed to a highly positive event than a highly positive plus mildly positive one. When the events had similar affective intensities, however, summation effects were obtained—more was better. In demonstrating averaging and summation effects, we delineated situations in which more positive life events can be better (summation effects) and situations in which more can be worse (averaging effects). Results also ruled out several alternative accounts, including the peak-end rule, economic, affective forecasting, and an assimilation/contrast interpretation.     

Attributions of responsibility and affective reactions to decision outcomes

Immediate affective reactions to outcomes are more intense following decisions to act than following decisions not to act. This finding holds for both positive and negative outcomes. We relate this "actor-effect" to attribution theory and argue that decision makers are seen as more responsible for outcomes when these are the result of a decision to act as compared to a decision not to act. Experiment 1 (N = 80) tests the main assumption underlying our reasoning and shows that affective reactions to decision outcomes are indeed more intense when the decision maker is seen as more responsible. Experiment 2 (N = 40) tests whether the actor effect can be predicted on the basis of differential attributions following action and inaction. Participants read vignettes in which active and passive actors obtained a positive or negative outcome. Action resulted in more intense affect than inaction, and positive outcomes resulted in more intense affect than negative outcomes. Experiment 2 further shows that responsibility attributions and affective reactions to outcomes are highly correlated; that is, more extreme affective reactions are associated with more internal attributions. We discuss the implications for research on post-decisional reactions.     

Facial Affect and Verbal Context in Conversation

This study examines affective facial expression in conversation. Experiment 1 demonstrates that the accuracy of affect-identification for conversational facial expressions generally is no better than chance. The explanation explored by Experiment 2 is that many conversational facial expressions operate as nonverbal interjections. Thus, much like verbal interjections (“gosh,”“really,”“oh please,”“jeez,” etc.), the attribution of affect for certain conversational facial expressions should depend on their verbal context. Experiment 2 supports the notion of facial expression as interjection by demonstrating that most any conversational facial expression, regardless of Us true source emotion or of the affect it signals in isolation, tends to be interpreted according to the affect associated with the verbal context in which it occurs. In addition to the identification of context-dependent interjection as yet another function of facial expression, the study suggests a pressing need for further investigation of nonverbal behavior in natural-conversation settings.     

Tragedy or tragicomedy: Mixed feelings induced by positive and negative emotional events

Based on the theory of appraisal, we predicted that positive and negative events happening to the same people or things in a specific chronological order (i.e., a negative event following a positive event) would induce different mixed feelings than the same events happening to different people or things. Pairs of emotional pictures with different captions were used to create two event groups. In the “tragic event” group, the positive and negative events happened to the same person or things, and in the “tragicomic event” group, the positive and negative events happened to different people or things. We designed two experiments to explore and compare the generation of mixed feelings in those two groups. In Experiment 1, the negative event was shown first, and in Experiment 2, the negative event was shown second (although the chronological order of the depicted events was the same). The participants were 381 undergraduates: 195 in Experiment 1 and 186 in Experiment 2. In both experiments, we found that tragic events introduced less intense mixed feelings than did tragicomic events due to fewer pleasurable feelings induced by the tragic events. There was no significant difference in the report of negative emotions between the groups. Appraisal theory and negative bias effects may explain these results.     

信念与结果对道德、法律责任判断的影响

在"执行者"和"旁观者"两个情境中,通过操纵当事人的信念和事件结果,考察了被试的道德与法律责任判断。结果显示:进行道德责任判断时,被试对当事人的信念信息更敏感;进行法律责任判断时,则对事件结果的信息更敏感。"执行者"情境中的道德和法律责任评分均高于"旁观者"情境中的责任评分。这说明道德、法律责任判断的内部机制有所不同,并且当事人的不同角色导致第三方对其的责任判断出现差异。     

越努力去忘就越能忘记吗？—情绪材料定向遗忘的"剂量效应"

采用项目法定向遗忘研究范式,在两个实验中分别使用情绪性语词和图片材料,考察主观努力程度影响情绪材料定向遗忘的心理机制。研究采用2(语词或图片情绪效价：正词/负词)×2（指示符：记住/忘记)×3（努力程度：20%/60%/100%）的被试内设计,因变量为情绪性语词或图片的再认率和定向遗忘效应。结果表明,正效价词在三种努力程度忘记条件的再认率无差别,而越努力去忘记负效价词,反而越能记住;正负效价的图片材料都呈现出越努力去忘记反而越能记住的特点。以上结果表明,语词与图片分别适合有意识加工和无意识加工,记住指令导致对情绪性语词和图片的选择性复述,符合选择性复述/被动衰退理论,而不同努力程度的忘记指令又引发了对情绪性语词和图片的主动抑制,符合注意抑制/执行控制理论。     

词语后情绪环境对语义和感知加工的影响

词语后情绪环境对其中的事件记忆产生影响,但是事件后情绪环境如何影响记忆加工仍不清楚。不同的情绪环境理论—“唤醒偏向竞争理论”,“拓宽-建构理论”,“记忆中心的积极情绪促进理论”支持情绪促进的不同本质。已有的研究表明,注意在情绪记忆中有重要作用。实验一、实验二分别探讨词语后情绪环境对其语义加工与内源源加工和外源源加工的影响。与中性环境相比,积极与消极情绪环境阻碍了外源源特征的加工; 与中性环境和积极情绪环境相比,消极情绪环境阻碍了内源源特征的加工。实验结果支持“唤醒偏向竞争理论”,同时表明“评估”和“注意放置”在情绪环境影响中的重要作用。     

Why a Big Mac Is a Good Mac: Associations between Affect and Size

Evaluation is a core topic of interest in both social psychology and linguistic theory, but there are relatively few social-cognitive studies examining the “online” consequences of affective metaphor. The experiments presented here sought to investigate such online consequences in relation to an understudied class of metaphors linking evaluation to size (i.e., “bigger is better”). Consistent with such metaphors, we found that positive (vs. negative) words were evaluated more quickly (Experiment 1) and accurately (Experiment 2) when presented in a larger (vs. smaller) font size. Parallel and opposite effects were found for negative words. A third experiment demonstrated that words presented in a larger font size were evaluated more favorably, thus extending size effects to evaluative judgments. Together, the studies converge on the importance of size metaphors for understanding evaluation from a social-cognitive perspective.     

The role of causal attributions in competitive situations

Previous data have shown that successful women are judged to have masculine characteristics [J. A. Doyle (1989), The Male Experience(2nd ed.), Dubuque, IA: Wm. C. Brown; D. L. Gill (1986), Psychological Dynamics of Sport,Champaign, IL: Human Kinetics; D. J. Murphy (1988), “Sport and Gender,” in W. M. Leonard II (Ed.), A Sociological Perspective of Sport(3rd ed.), New York: Macmillan; P. Willis (1994), “Women in Sport in Ideology,” in S. Birrell and C. L. Cole (Eds.), Women, Sport, and Culture,Champaign, IL: Human Kinetics]. Two experiments were conducted to test two different explanations for this effect, the appraisal and attribution hypotheses. In Experiment 1, male participants who lost to a female confederate on a masculine-relevant task rated her as having more masculine and fewer feminine characteristics than when the task was described as feminine-relevant. However, heart rate and blood pressure data failed to support the appraisal hypothesis that these reactions were due to the stress of losing to the female, or defensiveness. The alternative hypothesis that these ratings were due to standard attributional processes was more consistent with the data. Consequently, this hypothesis was tested in Experiment 2 using an attributional paradigm. Consistent with Experiment 1, the attribution hypothesis fared better than did the appraisal hypothesis.
