经济决策中人际信任博弈的理论模型与脑机制

信任是指个体在缺乏足够信息来判断他人动机、意图和行为的情况下,将社会资源交给对方处置并承担相应风险的意愿。作为一种基本的社会信号机制,信任对于发展和维持良好社会关系具有重要作用。借助信任博弈范式,研究者揭示了人际信任的认知神经机制并建构了多种理论,包括背叛厌恶理论、社会规范理论、道德规范理论和默认行为模型。脑成像研究发现信任行为主要涉及内侧前额叶、尾状核、杏仁核和脑岛等脑区,其中内侧前额叶主要参与心理推理、情绪认知与调控等过程,尾状核参与同伴值得信赖性的习得与编码,杏仁核和脑岛则主要参与风险、不确定性和背叛恐惧加工。今后研究应侧重不同理论之间的补充与整合,强化不同脑区之间的功能连接与整体性,并注重信任行为中的个体差异。     

从信任违背到信任修复:道德情绪的作用机制

早期学者已经从认知的角度分析信任违背的原因及修复方式。近年来,情绪对信任修复的影响引起了重点关注,但是情绪在其中的作用机制并未得到解答。当前的研究主要从情绪影响信任的线索依赖效应和离散情绪(内疚、羞愧、愤怒、悲伤等)对信任修复的影响这两个角度着手研究情绪对信任修复的影响。通过文献梳理发现内疚和共情两种道德情绪是影响信任修复最重要的情绪因素:内疚能够促进受信方做出补偿行为,共情能够促进信任方宽恕他人。基于此构建了道德情绪的信任修复模型,并考虑了目标线索和信任方的特质性宽恕的调节作用。同时建议未来的研究进一步探讨其他离散情绪尤其是道德情绪对信任修复的作用,并关注情境与情绪的交互作用。     

Predicting Driver's Intention Based on Own Vulnerability: A Social Interaction Process between Road Users at an Intersection in Japan

When road users predict the future movement of an approaching vehicle at an intersection, they need to consider not only the physical environment but also the predicted behavioral intention of the approaching driver. In the present experiments, we asked participants to imagine how a vehicle would approach in a natural traffic environment. In Experiment 1, participants estimated the time‐to‐contact with an approaching vehicle as longer when they were physically vulnerable. In Experiment 2, we confirmed that differences in participants’ eye height did not explain the findings of Experiment 1. In Experiment 3, we asked participants to indicate the last possible moment at which they could cross an intersection in front of an approaching vehicle. Participants left a shorter safety margin when they were more physically vulnerable than the approaching vehicle. The results indicate that road users’ perceived vulnerability is a cue for them to trust the approaching driver's intention to decelerate. This viewpoint is important for interventions to prevent unrealistic trust that an approaching vehicle will avoid an accident and subsequent trust‐based behaviors.     

Trust and Involvement as Higher-Order Factors of General Attitudes Towards Politics. Testing a Structural Model Across 26 Democracies

Interindividual differences in how people think and feel about politics have been investigated for decades. However, the great number of attitudinal concepts that has been developed to describe these differences is likely to distract from their conceptual overlap and dimensional structure. In addition, not much is known about the cross-cultural invariance of their interrelation. We propose that attitudes towards politics can be structured by two broad higher-order factors, a factor of general political involvement and a factor of general political trust. In two studies (N₁ = 767; N₂ = 29,018), including representative samples from 26 democracies, we first conduct several confirmatory factor analyses (CFA) to show that the higher-order model is a well-fitting and parsimonious alternative to a baseline model without higher-order factors in most samples. Second, we present evidence from multigroup CFA that the overall patterns of factor loadings are the same across all 26 countries. We interpret this structural equivalence across different democracies as support for the assumption that general political involvement and general political trust reflect basic orientations towards politics that are based on (1) demands of democratic political systems and (2) universal principles in human trait structure.     

Psychometric properties of Spanish version of the Mini-Mental Adjustment to Cancer Scale

Background/ObjectiveThe aim of the study was to examine the factor structure and psychometric properties of the Spanish version of the Mini-Mental Adjustment to Cancer Scale (Mini-MAC) in a large sample of patients with non-metastatic, resected cancer.MethodsProspective, observational, multicenter study for which 914 patients were recruited from 15 Spanish hospitals. Exploratory and confirmatory factor analyses, validity and reliability analyses were conducted.ResultsFactor-analytic results indicated a 4-factor structure of the Spanish version of the Mini-MAC. Three subscales have psychometric properties similar to those of Helplessness, Anxious preoccupation, and Cognitive avoidance of the original the Mini-MAC. The Fighting spirit and the Fatalism subscales were combined on the Positive attitude scale. The four factor-derived scale scores exhibited acceptable accuracy for individual measurement purposes, as well as stability over time in test-retest assessments at 6 months. Validity assessments found meaningful relations between the derived scale scores, and Brief Symptom Inventory depression and anxiety scores and Functional Assessment of Chronic Illness Therapy spiritual well-being scores.ConclusionsThe Spanish version of the Mini-MAC provides reliable and valid measures for patients with non-metastatic, resected cancer, and results corroborate the instrument’s cross-cultural validity.     

Epistemic buck-passing and the interpersonal view of testimony

Two ideas shape the epistemology of testimony. One is that testimony provides a unique kind of knowledge. The other is that testimonial knowledge is a social achievement. In traditional terms, those who affirm these ideas are anti-reductionists, and those who deny them are reductionists. There is increasing interest, however, in the possibility of affirming these ideas without embracing anti-reductionism. Thus, Sanford Goldberg uses the idea of epistemic buck-passing to argue that even reductionists can accept the uniqueness of testimonial knowledge, and Jennifer Lackey gives both speaker and hearer an essential role in testimonial justification, rejecting both reductionism and anti-reductionism in favor of what she calls dualism. After distinguishing a weaker and a stronger notion of buck-passing, we show how anti-reductionists can use the stronger notion to motivate their position, and to answer Goldberg’s and Lackey’s challenges.     

In Politics We Trust…or Not? Trusting and Distrusting Demonstrators Compared

This article sheds light on the debate regarding political trust and protest activity. The debate boils down to the question whether trust in politics is positively or negatively related to protest activity. We exploit a dataset encompassing data on about 9,000 demonstrators spread over seven European countries. These demonstrators' trust in their parliaments varies widely, ranging from trustworthy capable, to corrupt incapable. We examine the diverging sociodemographic profiles and motivational dynamics that turn distrusting and trusting citizens into demonstrators. We hypothesize and show that distrusting demonstrators turn their back to institutionalized politics; for them, demonstrating substitutes the party politics they distrust. For trusting demonstrators, demonstrating supplements party politics. Trusting and distrusting demonstrators also differ considerably in terms of motivation. Distrusting demonstrators are stronger motivated to demonstrate than trusting demonstrators. Moreover, while political cynicism amplifies the motivation of distrusting demonstrators, it suppresses the motivation of trusting demonstrators. We conclude that the question to be answered is not so much whether people who engage in protest activity trust or distrust their political elites, but rather who the trusting and distrusting protesters are and why they protest.     

Social Value Orientation,Expectations, and Cooperation in Social Dilemmas: A Meta‐analysis

Interdependent situations are pervasive in human life. In these situations, it is essential to form expectations about the others' behaviour to adapt one's own behaviour to increase mutual outcomes and avoid exploitation. Social value orientation, which describes the dispositional weights individuals attach to their own and to another person's outcome, predicts these expectations of cooperation in social dilemmas—an interdependent situation involving a conflict of interests. Yet, scientific evidence is inconclusive about the exact differences in expectations between prosocials, individualists, and competitors. The present meta‐analytic results show that, relative to proselfs (individualists and competitors), prosocials expect more cooperation from others in social dilemmas, whereas individualists and competitors do not significantly differ in their expectations. The importance of these expectations in the decision process is further highlighted by the finding that they partially mediate the well‐established relation between social value orientation and cooperative behaviour in social dilemmas. In fact, even proselfs are more likely to cooperate when they expect their partner to cooperate. Copyright © 2018 European Association of Personality Psychology     

Trust in organization as a moderator of the relationship between self‐efficacy and workplace outcomes: A social cognitive theory‐based examination

Drawing on a social cognitive theory perspective, we contend that an employee's trust in oneself, or self‐efficacy, will interact with the individual's trust in the system, or trust in organization, to predict job attitudes and behaviours. Specifically, we expected that self‐efficacy would have stronger effects on job attitudes (job satisfaction and turnover intentions) and behaviours (task performance and organizational citizenship behaviours) to the degree to which employees perceive high levels of trust in organization. Using data collected from 300 employees and their respective supervisors at a manufacturing organization in Turkey across three waves, we found that self‐efficacy had more positive effects on job satisfaction, task performance, and citizenship behaviours when trust in organization was high. Interestingly, self‐efficacy had a positive effect on turnover intentions when trust in organization was low, indicating that high trust in organization buffered the effects of self‐efficacy on intentions to leave. The results suggest that the motivational value of trust in oneself is stronger to the degree to which employees also have high trust in the system, whereas low trust in system neutralizes the motivational benefits of self‐efficacy.

Practitioner points

• Practicing managers should not only invest in increasing self‐efficacy of their employees, but also invest in building trust to improve employees’ attitudes, behaviours, and performance. This is because when employee trust in organization is high, employee self‐efficacy has greater potential to have a positive influence over job satisfaction, task performance, and organizational citizenship behaviours.
• Self‐efficacy may actually increase an employee's desire to leave the organization when organizational conditions are unfavourable, such as in the case of low trust in the organization. Practicing managers should be aware that employees who have high levels of confidence may be at higher risk of turnover when they are unhappy with the organization.
