社会公平感、机构信任度与公共合作意向

社会公平从古至今都是人类追求的崇高社会理想。对社会公平的感知即社会公平感直接决定着个体的机构信任,并影响其公共合作参与。本研究将社会公平感分为分配公平和程序公平,将机构信任度分为工具信任和动机信任,采用实验室情境设计的方法,引入最后通牒博弈和免责博弈范式,通过2个实验系统探讨"公正无私,一言而万民齐"的因果机制。研究发现分配公平与程序公平正作用于个体的公共合作态度与意向,在此基础上建立起公共合作的双路径模型:外部路径由分配公平产生工具信任和动机信任,进而触发公共合作;内部路径由程序公平产生动机信任和工具信任,进而触发公共合作;二者结合构成个体参与公共合作的双动力系统。双路径模型的适用性在组织情境和社会情境下均得到了支持。     

信任博弈范式真的能测量信任吗?

信任博弈范式测量信任的有效性一直存在争议。一方面, 社会偏好与风险偏好可能在范式变动中对投资信任水平产生影响, 降低信任博弈的内部效度。另一方面, 信任博弈与量表信任的相关水平较低, 这可能和态度与行为差异、测量类型差异以及测量范式的不足有关。虽然存在争议, 但总体而言, 信任博弈范式仍然是较为适宜的信任测量手段。未来信任博弈范式可在：验证信任博弈范式变动的科学性; 进一步澄清信任博弈范式与量表信任的低相关问题; 拓展信任博弈范式的测量维度以及提升信任博弈范式的生态效度等方面继续完善。     

Should Versus Want: On the Relative Contribution of Injunctive Norms and Preferences on Trust Decisions

Despite much research on the determinants of trust among strangers, its mechanisms are understood only rudimentarily. Recently, it has been proposed that people trust strangers because they believe they should, thus complying with an injunctive norm even if it conflicts with their preferences. However, given the boldness of this claim and in light of independent arguments and earlier findings that suggest otherwise, the hypothesis requires critical scrutiny. Thus, we tested whether the decision to trust (in the trust game) is indeed more strongly driven by what people think they should entrust rather than what they want to entrust in two studies. We consistently found a stronger influence of “want” than of “should” on trust decisions even when controlling for the fairness aspect inherent in the trust game. Thus, our findings speak against a predominant role of injunctive norms for trust behavior and confirm that the latter is mostly driven by preferences. Copyright © 2016 John Wiley & Sons, Ltd.     

What you don’t know won’t hurt me: Costly (but quiet) exit in dictator games

We used simple economic games to examine pro-social behavior and the lengths that people will take to avoid engaging in it. Over two studies, we found that about one-third of participants were willing to “exit” a $10 dictator game and take $9 instead. The exit option left the receiver nothing, but also ensured that the receiver never knew that a dictator game was to be played. Because most social utility models are defined over monetary outcomes, they cannot explain choosing the ($9, $0) exit outcome over the dominating $10 dictator game, since the game includes outcomes of ($10, $0) and ($9, $1). We also studied exiting using a “private” dictator game. In the private game, the receiver never knew about the game or from where any money was received. Gifts in this game were added innocuously to a payment for a separate task. Almost no dictators exited from the private game, indicating that receivers’ beliefs are the key factor in the decision to exit. When, as in the private game, the receivers’ beliefs and expectations cannot be manipulated by exit, exit is seldom taken. We conclude that giving often reflects a desire not to violate others’ expectations rather than a concern for others’ welfare per se. We discuss the implications of our results for understanding ethical decisions and for testing and modeling social preferences. An adequate specification of social preferences should include “psychological” payoffs that directly incorporate beliefs about actions into the utility function.     

计算模型视角下信任形成的心理和神经机制——基于信任博弈中投资者的角度

人际信任渗透在社会交互的各个方面, 是促进和维持合作的重要基石。以往研究者借助信任博弈范式, 主要探讨了人际信任的理论模型、生物基础和影响因素等方面。近年来, 研究者开始将计算模型应用于信任博弈的数据分析中, 深入挖掘人际信任行为背后的心理机制, 将计算模型与神经影像技术结合, 加深对信任行为背后脑机制的理解。目前将计算模型应用于信任博弈范式中的研究主要针对“信任是如何形成的”这一科学问题, 未来要进一步发展计算模型方法, 结合非侵入性脑刺激技术, 应用于精神疾病人群中, 以深入理解正常和异常信任形成的心理和神经机制。     

Effects of trustors' social identity complexity on interpersonal and intergroup trust

Although previous literature has revealed the effect of a single social identity on trust, only few studies have examined how multiple social identities affect trust in others. The present research examined the effects of trustors' social identity complexity on their level of trust toward another person (interpersonal trust), outgroup members (outgroup trust), and ingroup members (ingroup trust). Study 1, which was a correlational study, indicated that trustors' social identity complexity was positively related to their interpersonal and outgroup trust. Three experimental studies were performed to identify causal relationships. Study 2 found that activating trustors' high social identity complexity produced high levels of interpersonal trust, and Studies 3 and 4 found that this effect was more pronounced when the trustee was an outgroup member (outgroup trust) rather than an ingroup member (ingroup trust). The implications of these results for social harmony are discussed.     

The Psychology (and Economics) of Trust

Interpersonal trust is a mental construct with implications for social functioning and economic behavior. We review contemporary theories of trust from behavioral economics and social psychology. Neoclassical economic theory considers trust in strangers to be irrational, but observed behavior reveals widespread trust and trustworthiness. Theories of social preferences and adherence to social norms have been proposed to rationalize trust. Psychological approaches investigate trusting behavior in terms of an underlying disposition, intergroup processes, and cognitive expectations. The breadth of these approaches illustrates the multi‐faceted nature of trusting behavior. The determinants of trust are related to the relevant characteristics of the individual, the situation, and their interaction.     

An intermediary enhances out‐group trust and in‐group profit expectation of Chinese but not Australians

In this research, we made a theoretical distinction between direct and intermediary‐mediated trust situations, and conducted a cross‐cultural (Chinese vs. Australians) investment trust game to test the overlooked effects of an intermediary on investors' trust decisions, with respect to how much to invest in and expect from trustees. Compared to situations of direct trust, a nominal intermediary increased the number of Chinese investors expecting in‐group trustees to repay a profit on their investments (Hypothesis 1) and raised their level of investment in out‐group trustees (Hypothesis 2). These results applied to Chinese, but not Australians in support of the proposal that a nominal intermediary would serve as a cue to activate different cultural stereotypes of the functions and meanings of an intermediary with respect to trust and expectation of reciprocity. Coexisting with these culture‐specific effects of an intermediary, the minimal categorisation of people into in‐group and out‐group on trivial grounds leads to a highly significant in‐group favouritism in investment levels of both Chinese and Australians (Hypothesis 3).     

Social game theory: Preferences,perceptions, and choices

ABSTRACT

Building on classic game theory, psychologists have explored the effects of social preferences and expectations on strategic behaviour. Ordinary social perceivers are sensitive to additional contextual factors not addressed by game theory and its recent psychological extensions. We review the results of a research programme exploring how observers judge “players” (i.e., individuals making strategic decisions in social dilemmas) on the dimensions of competence and morality. We explore social perception in several well-known dilemmas, including the prisoner’s dilemma, the volunteer’s dilemma, and the trust dilemma. We also introduce a novel self-presentational dilemma. In research conducted over a decade and a half, we have found that judgements of competence are sensitive to both players’ choices and the dilemma’s (expected and actual) outcomes. In contrast, judgements of morality respond strongly to players’ behaviour and little else. We discuss how these social-perceptual patterns might affect expectations, preferences, and strategic choices.     

重复信任博弈的决策过程与结果评价

“信任他人或者不信任他人?”是社会互动中经常面临一种行为决择, 直接影响着个体的社会生活。作为一种重要的社会信号机制, 信任是建立良好社会关系的基石, 它能够降低社会交易成本, 易化合作行为。为了探究个体在信任互动情境下大脑活动变化的时间动态特征, 采用事件相关电位技术记录了20名健康被试(充当信任者)完成重复性信任博弈任务(repeated Trust Game, rTG)时的脑电成分。行为结果发现个体选择信任的比例显著高于几率水平。电生理学结果表明, 决策阶段中不信任选择比信任选择诱发了更正的P2成分(150~250 ms), 差异波溯源分析定位于额中回(middle frontal gyrus, BA 46)和额下回(inferior frontal gyrus, BA 46)。反馈阶段中损失反馈比获益反馈诱发了更负的FRN成分(200~300 ms), 而获益反馈比损失反馈诱发了更短的P300潜伏期。本研究为理解人类信任博弈过程的动态加工时程提供了初步的神经电生理学证据。     

日常环境中的暴力暴露对攻击行为的长期影响:一个有调节的中介模型

以850名大学生为被试,探讨日常环境中的暴力暴露与攻击行为的关系,并在此基础上提出一个有调节的中介模型,考察攻击性信念的中介作用和人际信任的调节作用。结果发现:(1)日常环境中的暴力暴露对攻击行为有显著的正向预测作用;(2)攻击性信念在日常环境中的暴力暴露与攻击行为的关系中起部分中介作用;(3)攻击性信念的中介作用会受到人际信任的调节。对于低人际信任个体,攻击性信念起部分中介作用;对于高人际信任个体,攻击性信念的中介效应不显著,日常环境中的暴力暴露对攻击行为只有直接作用。     

A Social Dilemma Analysis of Commuting Preferences: The Roles of Social Value Orientation and Trust1

The current research advances a social dilemma analysis of commuting, examining the roles of preexisting personality differences in social value orientation (i.e., prosocial vs. proself orientation) and trust (i.e., a general belief in the honesty and cooperative intentions of others) in determining preferences for collectively desirable commuting options: preferences for commuting by public transportation (Study 1) and carpooling (Study 2). Consistent with predictions, both studies revealed that, relative to p of prosocials, preferences of proselfs were more strongly associated with beliefs about the relative efficiency of cars (i.e., an outcome affecting personal well-being). Also, greater preferences for collectively desirable actions were observed among prosocials with high trust—relative to prosocials with low trust and proselfs with high or low trust—providing support for the claim that 2 conditions (i.e., prosocial goals and trust in others) must be met to obtain collectively desirable commuting preferences.     

冲突情境下幼儿的选择性信任和信念修正

幼儿如何选择性地采信他人提供的信息、获取知识, 是幼儿社会认知发展研究的重要问题。除客观的信息内容外, 信息传递者的特征也影响幼儿的选择性信任。另外, 在不确定情境下, 他人证言与幼儿已有信念可能存在冲突, 在二者冲突的情境下, 幼儿是否可以采信他人的证言, 并最终改变幼儿的已有判断是以往研究忽略的问题。本研究考察了当母亲证言与幼儿已有信念冲突时, 不同程度的冲突情境(面对不同比例的合成动物时)对幼儿选择性信任和信念修正的影响。研究采用冲突信息源范式, 向74名4~6岁幼儿呈现对不同比例合成动物(50%-50%任务 vs 75%-25%任务)命名的证言, 考察幼儿对信息提供者的询问意愿、对证言的信任情况和在证言前后对合成动物的判断(信念修正)。信息提供的一方为母亲(提供相似度低的动物名称), 另一方为陌生人(提供相似度高的动物名称)。结果发现, 幼儿的选择性信任和信念修正受到母亲证言与已有信念冲突程度的影响。在低冲突情境下, 幼儿对母亲证言的询问意愿和外显信任均高于高冲突情境。幼儿的信念修正存在年龄差异, 在低冲突情境下, 年长幼儿比年幼幼儿更倾向于改变已有信念, 在高冲突情境下, 年长的幼儿比年幼幼儿更不愿意改变已有信念。本研究结果表明, 当母亲的证言与幼儿已有信念冲突时, 中国幼儿可以区分不同程度的冲突情境, 并且可以根据冲突的程度进行选择性信任和信念修正。     

Decision-makers use social information to update their preferences but choose for others as they do for themselves

People's risky decisions are susceptible to the social context in which they take place. Across three experiments using different paradigms, we investigated the influence of three social factors upon participants' decisions: the recipient of the decision-making outcome (self, other, or joint), the nature of the relationship with the other agent (friend, stranger, or teammate), and the type of information that participants received about others' preferences: none at all, general information about how previous participants had decided, or information about a specific partner's preference. We found that participants' decisions about risk did not differ according to whether the outcome at stake was their own, another agent's, or a joint outcome, nor according to the type of information available. Participants did, however, adjust their preferences for risky options in light of social information.     

Is behavioral pro-sociality game-specific? Pro-social preference and expectations of pro-sociality

We observed the behaviors of the same people across five games – two prisoner’s dilemma games, a trust game (in which the subject took on the role of both truster and trustee), a dictator game, and a faith game – any pair of which was separated by an interval of several months to reduce potential carry-over effects, and found strong consistency in behaviors among these games. We also found consistency between the expectations of other players’ behaviors and the player’s own behavior across games. We further found that the consistent behavioral pro-sociality observed across different games was related to the general measures of pro-social value orientation and perceiving the game situations. These findings suggest that individual and cultural differences in game behaviors can reflect both the ways in which people perceive game situations and their general social preferences.     

It's only a dream if you wake up: Young adults' achievement expectations,opportunities, and meritocratic beliefs

The present paper examines university graduates' beliefs about how meritocratic socioeconomic status (SES) attainment in U.S. society is for themselves (merit agency beliefs) and for most other people (merit societal beliefs), and how these distinct beliefs are differentially associated with labour market experiences and achievement‐goal attitudes and expectations in the aftermath of the Great Recession. Data from a 10‐month longitudinal study of 217 graduates from the 2013 class of a large public U.S. university were analysed using multilevel modelling. The results indicate that most participants optimistically expected to attain upward social mobility. Furthermore, participants' merit agency beliefs were reflective of their labour market prospects and experiences, and calibrated their achievement‐goal attitudes and expectations. However, participants' merit societal beliefs were not associated with these labour market experiences and achievement‐goal attitudes and expectations. The distinction between merit agency beliefs and merit societal beliefs may be motivationally beneficial by allowing individuals to continue striving toward the uncertain long‐term goal pursuit of upward social mobility despite the short‐term struggles and setbacks many young adults are likely to experience in the aftermath of the Great Recession.     

Cross-Sectional and Longitudinal Relations Among Children's Trust Beliefs,Psychological Maladjustment and Social Relationships: Are Very High as Well as Very Low Trusting Children at Risk?

Four hundred and thirty-four children enrolled in school years 5 and 6 in the United Kingdom were administered measures of trust beliefs in peers/best friends and psychosocial functioning (internalized maladjustment, self-perceived social acceptance, social preference, and social exclusion) across an 8-month period (mean age = 9 years − 9 months at Time 1). The relation between children's trust beliefs in peers or trust beliefs within best friend dyads and measures of psychosocial functioning conformed to a quadratic pattern. Compared to children in the middle range of trust beliefs, children with very low trust beliefs and those with very high trust beliefs in peers and/or within best friend dyads displayed higher internalized maladjustment, lower self-perceived social acceptance, higher social exclusion, and lower social preference. The relation between the trust beliefs and internalized maladjustment was asymmetrical, with children who held very low trust beliefs being comparatively more disadvantaged.     

信任的跨文化差异研究：视角与方法

信任作为一种复杂的社会心理现象,其相关研究不能脱离个体所处的文化背景。个体在一般信任水平,信任的建立方式,信任的种类及信任修复的方式等方面都存在着显著的文化差异。信任存在文化差异的主要原因在于个体对线索的提取方式不同、所处社会文化情境不同及文化的变迁。量化研究和质性研究相结合的方法是信任研究主要采用的方法,其中卡片分类与深度访谈相结合法、“桌面游戏”法最受研究者的青睐。未来的研究应该进一步探查信任的本土化概念,并关注全球化背景下不同文化下个体的人际信任建立的问题。     

感知社会善念对信任修复的促进：社会距离与时间距离的调节作用

从信任修复的时间阶段模型来看,以往研究主要探讨了信任违背发生后的修复策略及效果,而鲜有研究从违背前的视角对此展开探索。为检验社会善念能否作为信任修复的‘事前’策略及其修复效果的边界条件,本研究采用Somi范式操纵违背方的社会善念,通过让信任方完成信任博弈游戏来考察其感知到的社会善念对信任修复的效果及社会距离与时间距离在其中发挥的调节作用。实验1结果表明,感知社会善念有助于促进受损信任的修复,感知高(vs.低)社会善念的被试修复效果更好;实验2发现社会距离调节了感知社会善念对信任修复的影响,面对社会距离远(vs.近)者的信任违背,感知到高社会善念的被试有更好的修复效果;实验3不仅再次验证了前两个实验的发现,还进一步发现时间距离调节了社会距离与感知社会善念对信任修复的影响,即当社会距离远的违背方回应时间距离短时,感知高社会善念的被试修复效果更好,当社会距离近的违背方回应时间距离长时,感知高社会善念的被试修复效果更好。由此可见,违背发生前信任方感知到违背方的社会善念能在一定程度上修复受损信任,但其效果受到社会距离与时间距离的制约。这些发现对未来探讨信任修复的事前策略及社会善念理论的应用均有一定启示意义。     

Trust and trustworthiness in a sequential bargaining game

We use a two‐person extensive form bargaining game to explore individuals' trusting and reciprocal behavior and how those relate to their scores on a trust survey. In keeping with prior research, we find that the ‘self‐interested’ outcome is rejected by a majority of individuals. People who score high on the trust survey are both trusting and are also trustworthy, in that they reciprocate others' trust. But people with low‐trust scores often exhibit trust but are not trustworthy. These ‘inconsistent trusters’ seem to be interested in exploiting the trust and trustworthiness of others in increasing their own payoff. Copyright © 2003 John Wiley & Sons, Ltd.
