10～12岁儿童社会价值取向对第三方利他行为的影响：情绪的作用

为探讨10～12岁儿童社会价值取向与第三方利他行为的关系,实验1采用第三方惩罚范式,招募233名儿童被试,实验2采用第三方补偿范式,招募238名儿童被试,考察三种分配(高度不公平、中度不公平和公平)情境下社会价值取向、情绪对第三方利他行为的影响,并对比两个实验的结果。结果显示:(1)在第三方惩罚任务中亲社会儿童(相比亲自我)在高度不公平情境下拿出更多金币用于惩罚分配者;(2)在第三方补偿任务中亲社会儿童(相比亲自我)在两种不公平情境下都拿出更多金币用于补偿接受者;(3)情绪只在高度不公平情境下在社会价值取向与第三方利他行为之间发挥中介作用;(4)采用第三方补偿(相比第三方惩罚)的儿童面对不同分配时情绪波动更小,在中度不公平情境下有更多利他行为。这些结果从发展的角度为社会价值取向对第三方利他行为的影响机制提供证据,强调了亲社会取向对维护社会公平的重要作用。     

公平与惩罚价格对第三方惩罚需求的影响

为了探讨第三方惩罚的影响因素,分析个体在不同公平情境下面临不同的惩罚成本时会采取怎样的第三方惩罚行为,本研究以171名大学生为被试,采用2×2的混合实验设计,通过设置高低两种不公平情境和3种惩罚价格,对被试的第三方惩罚需求进行实验研究。结果显示,个体的第三方惩罚需求都有随着惩罚价格的升高而降低的趋势;不公平程度显著影响第三方惩罚需求。研究表明,惩罚成本显著影响个体的第三方惩罚的实施;在低不公平情境中,被试面对不同惩罚成本时其第三方惩罚行为之间无显著差异,即各种惩罚成本下出现第三方惩罚行为的可能性均较小;而在高不公平情境中,被试面对不同惩罚成本时的第三方惩罚行为之间差异显著,惩罚成本越低出现第三方惩罚的可能性越大。     

得失情境下第三方惩罚决策差异的神经机制：基于rTMS的研究

本研究应用低频rTMS技术,通过在第三方惩罚（研究1）及第三方惩罚和第三方补偿（恢复性惩罚）并存的情况下（研究2）,对个体双侧vmPFC功能进行抑制,探索vmPFC在得失情境下第三方惩罚决策中的作用。研究1结果表明,rTMS抑制右侧vmPFC功能将降低损失情境下的第三方惩罚,收益情境下未发生改变。研究2得到与研究1一致的结果,且第三方惩罚减少程度更大,第三方补偿并未发生改变。这些结果强调了vmPFC与第三方惩罚紧密相关,在第三方判断得失情境的影响时起关键作用。     

支付与报复：成本形式对第三方惩罚的影响

第三方惩罚不仅对惩罚成本的数量敏感,也对成本形式敏感。在保持成本数量相等的情况下,不同形式的惩罚成本会对第三方惩罚的频率产生不同影响。相较支付形式,当惩罚成本采取报复形式时,被试的第三方惩罚频率显著下降。进一步的实验表明,惩罚频率的变化并非因为不同的成本形式所隐含的风险水平有所差异,而是因为被试对不同的成本形式赋予了不同的主观价值。进一步探索更多形式的惩罚成本是未来研究的重要方向。     

道德与关系惩罚对初中生公共物品困境中合作行为的影响

本研究模拟公共物品两难困境范式,以初中生为被试,通过两个实验分别考察道德惩罚和关系惩罚对不同性别和社会价值取向个体合作行为的影响。结果发现:(1)两种惩罚条件下初中生的合作水平均显著高于无惩罚条件,但当惩罚撤除后只有关系惩罚条件下的效应还存在;(2)初中女生在两种惩罚条件下的合作水平均显著高于无惩罚条件,而男生只在关系惩罚条件下出现该情况;(3)亲社会取向与亲自我取向初中生在两种惩罚阶段均表现出更高的合作水平,但在惩罚撤除后,只有亲社会取向者保持了高合作水平。这些结果表明,关系惩罚的作用较为持久,且对男生的影响更为突出,不过两种惩罚在亲社会取向者身上均显现出延后效应。     

行为意图信息对广义互惠行为的影响

广义互惠是指个体以他人对待自己的方式去对待其他陌生人。本研究通过独裁者博弈任务,考察了行为意图信息对广义互惠的影响。结果发现:(1)在慷慨分配情境中,行为有意条件下被试分配给陌生人的金钱显著多于无意图条件,而自私分配情境则相反;(2)只有负性意图条件下的被试,分配的金钱显著少于无意图条件,而后者与正性意图条件分配数额差异不显著。这表明行为意图信息能够调节广义互惠行为,且负性意图作用强于正性意图。     

财富越多，责任越大：资金数量和来源对公共物品困境中第三方惩罚的影响

本研究探讨了公共物品困境中,初始资金的数量和来源如何影响第三方对成员贡献值的评价及惩罚。行为结果发现了“贵族责任效应”,即在同等贡献值条件下,相比于获得较少初始资金的成员,第三方会更重地惩罚获得较多初始资金的成员。当初始资金是随机分配而非通过个人努力获得时,该效应更强。在神经层面上,发现初始资金的数量和来源调节了第三方评估贡献值时所诱发的FRN和P3成分。其中FRN波幅与惩罚力度显著相关。本研究揭示了初始资金数量和来源如何调节第三方对成员贡献的评估及相关惩罚决策。     

移情在道德强度对企业道德决策影响中的作用

摘 要 本研究将一种重要的道德情绪--移情引入问题权变模型中,以探讨移情因素在道德强度对企业道德决策影响中的作用。本研究基于情景研究法,随机选取256名MBA学生为被试,要求被试基于所提供情景中假想参与者的行为,回答随后测量道德决策(道德识别、道德判断和道德意图)、移情反应、主观道德强度及移情特质的问题。结果发现,1）移情反应在道德强度对企业道德决策的影响中具有中介作用;2）移情关怀特质会通过影响主观道德强度和移情反应而作用于企业道德决策;3)结果大小、社会舆论和效应可能性对道德判断和道德意图的影响机制各有特点。     

人情与公正的抉择:社会距离对第三方干预的影响

第三方干预(third-party intervention)是一种重要的利他行为,它包括惩罚和补偿两种措施。本研究结合情境性问卷与实验法,采用修改后的独裁者博弈范式(Dictator Game,DG),让被试作为第三方对朋友或者陌生人的不公平行为进行干预,考察社会距离对第三方干预的影响。研究发现:(1)对于朋友提出的不公平方案,个体对其的惩罚轻于陌生人,而对第二方(无权者)的补偿没有显著差异。(2)个体对朋友的不公平提议的公平性判断高于陌生人,但提议引发的情绪体验没有显著差异。上述结果表明,社会距离可能通过影响个体对不公平行为的公平感知,进而影响其第三方干预行为。     

第三方惩罚的神经机制：来自经颅直流电刺激的证据

第三方惩罚既是社会规范在群体得以维系的基石, 也是个体维护社会规范的体现。当前关注社会规范的神经研究大多基于第二方惩罚的独裁者或最后通牒实验框架, 缺乏对第三方维护社会规范过程中相关脑区活动的探索, 对这一过程的内在神经机制也不清楚。本文基于第三方惩罚的独裁者博弈框架, 对右侧背外侧前额叶区域(DLPFC)进行不同极性的经颅直流电刺激(tDCS), 同时依据第三方是否需要为其惩罚付出成本设计了零成本和有成本两个实验任务。结果发现, 第三方在零成本任务的情绪反应和惩罚显著受到tDCS设置的影响, 且阴极刺激显著提升了第三方的惩罚值, 这表明情绪机制对第三方惩罚有着重要影响。另外, 第三方在零成本和有成本任务中的惩罚差异在不同tDCS设置之间也存在显著差异, 这与第三方惩罚还受到自利机制影响的观点相符。本文率先为右侧DLPFC活动影响第三方惩罚提供了神经层面的证据, 且支持了第三方对社会规范的遵从与其负性情绪反应和自利加工密切相关的机制解释。     

Outcomes and intentions in children’s,adolescents’, and adults’ second- and third-party punishment behavior

Theories of morality maintain that punishment supports the emergence and maintenance of moral behavior. This study investigated developmental differences in the role of outcomes and the violator’s intentions in second-party punishment (where punishers are victims of a violation) and third-party punishment (where punishers are unaffected observers of a violation). Four hundred and forty-three adults and 8-, 12-, and 15-year-olds made choices in mini-ultimatum games and newly-developed mini-third-party punishment games, which involved actual incentives rather than hypothetical decisions. Adults integrated outcomes and intentions in their second- and third-party punishment, whereas 8-year-olds consistently based their punishment on the outcome of the violation. Adolescents integrated outcomes and intentions in second- but not third-party punishment.     

应激环境下亲社会性的增加：来自不同类型的亲社会偏好的研究证据

人们面临对生理或者心理产生威胁的应激事件时并不一定表现出敌意和攻击, 也可能表现出更强的亲社会性。研究发现, 基于利他动机、规则动机、策略性动机的或者基于自我报告的亲社会偏好在应激环境下都可能增强, 这可能和应激环境下直觉增强、共情提升和亲社会行为有助于改善负面情绪方面的机制有关。未来研究可以从应激的性质、诱发方式、影响机制、个体差异和发展特征等方面去理解应激增加亲社会性的条件, 从而提高群体韧性。     

Ambiguity attitudes in qualitative contexts: The role of prior beliefs

Most studies of ambiguity aversion rely on experimental paradigms involving monetary bets. Thus, the extent to which ambiguity aversion occurs outside of such contexts is much less understood, particularly when the situation cannot easily be reduced to numerical terms. The present work seeks to understand whether people prefer to avoid ambiguous decisions in a variety of different qualitative domains (e.g., work, family, love, friendship, exercise, study, and health), and, if so, to determine the role played by prior beliefs in those domains. Across three studies, we presented participants with 24 vignettes and measured the degree to which they preferred risk to ambiguity in each. We also asked them for their prior probability estimates about the likely outcomes in the ambiguous events. Ambiguity aversion was observed in the vast majority of vignettes, but at different magnitudes. It was predicted by whether the vignette involved gain or loss as well as by people's prior beliefs; however, the heterogeneity between people meant that the role of prior beliefs was only evident in an individual-level analysis (i.e., not at the group level). Our results suggest that the desire to avoid ambiguity occurs in a wide variety of qualitative contexts but to different degrees for different people and may be partially driven by unfavorable prior estimates of the likely outcomes of the ambiguous events.     

Can genetic risk information enhance motivation for smoking cessation? An analogue study.

Protection motivation theory and the extended parallel processing model are used to predict the motivational impact of information regarding a genetic susceptibility to heart disease. One hundred ninety-eight smokers read 1 of 3 vignettes: gene positive, gene negative, or standard smoking risk information. Analyses examined whether the impact of type of risk information was moderated by smokers' self-efficacy (SE) levels. Key outcomes were intention to quit and intention to attend an information session about quitting. There were significant main effects of SE and of receiving gene-positive risk information on intentions to quit. There was a significant Risk x SE interaction on intentions to attend an information session. SE was not associated with intentions to attend the information session for smokers in the gene-positive group. Intentions to attend the session were negatively associated with SE for smokers in the lower risk groups. Implications for using genetic risk information to motivate smoking cessation are discussed.     

Preference for modes of dispute resolution as a function of process and decision control

Research on procedural justice has suggested that the distribution of control among participants can be used to classify dispute-resolution procedures and may be an important determinant of preference for such procedures. This experiment demonstrates that control can be meaningfully divided into two components: control over the presentation of evidence and control over the final decision. The experiment placed subjects (law students and undergraduates) in a situation of conflict and varied two between-subjects factors: (1) Role, whether subjects expected to role-play third parties (law students) or litigants (undergraduates), and (2) Orientation, whether individuals focused on equity claims (appeals to a norm of fairness) or legal claims (appeals to a strict, legal interpretation of events). As a control, a third-party neutral-orientation condition was included. In addition, subjects were presented with four dispute-resolution procedures which varied in third-party control over the presentation of evidence (Process Control) and third-party control over the final decision (Decision Control) as within-subjects factors. Results revealed that both litigants and third parties preferred high rather than low third-party decision control. Litigants with an equity orientation preferred low third-party control over the presentation of evidence, particularly when third parties had high rather than low decision control. Third parties and litigants with a legal orientation preferred low rather than high third-party process control only when there was high third-party decision control. Litigant preferences were more affected by variation in process control than variation in decision control while third-party preferences were more affected by variation in decision control than in process control. As a check on external validity, military judges given a neutral orientation were asked to evaluate and express preferences for the four dispute-resolution procedures. Their results were not detectably different from those of the law students who role-played third parties in the main portion of the study.     

社会责任感调节群际替代性排斥中旁观者第三方惩罚

为了考察群体身份对替代性排斥中旁观者惩罚行为的影响,并考察旁观者社会责任感的调节作用,采用数量估计任务对58名不同社会责任感大学生创设群体身份,观看网络掷球游戏形成群际替代性排斥,随后评估游戏中各玩家的愤怒情绪,并采用第三方惩罚来表达对各玩家表现的愤怒。结果发现高社会责任旁观者对替代性排斥体验到更强愤怒情绪,并对排斥者施加更高惩罚;高社会责任感个体对排斥组内成员的组外排斥者惩罚强度高于组内排斥者,而低社会责任感个体对排斥组外成员的组外排斥者惩罚强度显著高于组内排斥者。结果表明旁观者社会责任感调节其在群际替代性排斥中的第三方惩罚。     

Acute stress eliminates female advantage in detection of ambiguous negative affect

The human stress response evolved to maximize an individual's probability of survival when threatened. The present study addressed whether physical danger modulates perception of an unrelated ambiguous threat and, if so, to what extent this response is sex- specific. The authors utilized a first-time tandem skydive as a stressor, which had been previously validated as producing a highly-controlled, genuinely stressful environment. In a counter-balanced within-subjects design, participants wore a virtual reality helmet to complete an emotion-identification task during the plane's ascent (stress condition) and in the laboratory (control condition). Participants were presented static male faces morphed between 20-80% aggression, which gradually emerged from degraded images. Using a binary forced-choice design, participants identified each ambiguous face as aggressive or neutral. Results showed that participants characterized emotion more rapidly under stress versus control conditions. Unexpectedly, the results also show that while women were more sensitive to affect ambiguity than men under control conditions, they exhibited a marked decrease in sensitivity equivalent to men while under stress.     

公正世界信念对第三方惩罚的影响：来自ERP的证据

采用事件相关电位技术（ERP）考察公正世界信念对第三方惩罚的影响。（1）行为结果显示,高公正世界信念个体的第三方惩罚显著多于低公正世界信念个体,低公正世界信念个体在高不公正提议下的第三方惩罚显著增加;（2）ERP结果显示,高公正世界信念个体比低公正世界信念个体诱发了更大的MFN波幅和更小的P300波幅,且高公正世界信念个体的MFN波幅在高、低不公正提议下没有差异,低公正世界信念个体在高不公正提议下的MFN波幅明显更大。这说明相比低公正世界信念个体,高公正世界信念个体所持有的公正认知强烈且稳定,个体做出第三方惩罚更多基于自身对于公正结果的预期,而非外部条件。     

Sphincter of Oddi dysfunction: Does Psychosocial Distress Play a Role?

Sphincter of Oddi dysfunction (SOD) is a functional gastrointestinal disorder characterized by pancreatobiliary-type of pain in the absence of organic abnormalities. The aim of this study was to investigate specific psychosocial predictors of functional outcome in a group of patients consecutively referred to a gastroenterological department for biliary-type of pain. Based on medical examination patients were divided into functional (SOD) and organic groups. Self-administered questionnaires regarding demographic characteristics, psychological distress (Symptom Check-List-90–R, [SCL-90-R]), severity of acute and chronic stress, level of subjective well-being and satisfaction with health were completed. The analyses were based on the logistic regression approach. In this sample, SOD patients were older than organic patients and more likely female. Logistic regression analysis showed that higher acute stress (i.e., main effect) was associated with a decreased likelihood of functional (SOD) outcome, whereas the combination of acute stress with chronic stress and the combination of acute stress with higher severity of psychopathology (i.e., interaction effect) was associated with an increased likelihood of functional (SOD) outcome. These findings suggest stressful life events in combination with certain psychological symptoms can play a role in the symptom presentation of patients with sphincter of Oddi dysfunction.
