共情对亲社会行为的影响及神经基础

亲社会行为是指那些使他人获益的行为,这类行为具有重要的进化意义和现实意义。作为影响亲社会行为的重要因素,共情在认知神经科学领域得到了广泛研究。脑岛等脑区的激活与消极情绪体验有关,是情绪共情的神经基础,利于产生亲社会行为动机;颞顶联合区等脑区参与对他人意图的理解,是认知共情的神经基础,利于个体选择有效方式帮助别人。女性在共情时激活额下回等与情绪有关的脑区,而男性在共情时激活颞顶联合区等与认知有关的脑区,这为男女个体在亲社会行为表现上的差异提供了新证据。未来研究应完善与亲社会行为有关的脑区功能的解释,综合多种影响因素,结合病理学研究考察共情对亲社会行为的影响及神经基础。     

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。     

自我惩罚：影响因素、模型与展望

自我惩罚是个体在违反社会规范后,自愿使自己承受伤害或蒙受损失的行为。自我惩罚会受到负性情绪、补救机会、代偿机会和性别的影响。情绪模型和互惠模型分别从情绪和互惠的角度阐述了自我惩罚的认知机制。根据近期的研究结果,可以推测自我惩罚与前扣带回、脑岛、右外侧眶额叶皮层、背内侧前额叶皮层、伏隔核、腹内侧前额叶皮层有关。未来值得研究的方向有：进一步确认自我惩罚涉及的情绪成分、为互惠模型收集更多实验证据、探究自我惩罚对集体合作的影响以及开展跨文化研究。

计算式互惠机制探讨——认知和动机的物种比较

与灵长类动物相比, 人类社会中存在广泛的互惠行为, 这种广泛性表现为人类具有独特的计算式互惠。本文从计算式互惠的认知和动机机制两方面对人类儿童和灵长类动物进行比较, 以期从近因机制的角度为人类互惠行为的复杂性提供解释依据。未来研究需要重视从个体发展和个体差异的视角探寻认知和动机因素对计算式互惠的影响, 并注重从互动双方各自的角度对各影响因素进行区别和分析, 从而更全面地提供有关人类互惠近因机制的证据。     

自我控制失败的理论模型与神经基础

自我控制指那些帮助人们克服思想和情绪, 进而依据实际情况调整自我行为的心理加工。虽然良好的自我控制对个体的成功与幸福非常重要, 但自我控制失败仍然是整个人类社会的核心问题。借助于序列任务范式, 研究者揭示了自我控制失败的认知机制并建构了多种理论, 包括能量模型、加工模型、中央管理器模型和前额叶−皮层下脑区的平衡模型。相关脑成像研究主要聚焦于额下回、杏仁核、眶额叶皮质等脑区。未来研究应侧重不同理论之间的融合与补充, 强化自我控制失败潜在神经机制的探索, 并推动自我控制与社会决策行为的关系研究。     

最后通牒博弈中的公平偏好:基于双系统理论的视角

在最后通牒博弈中,自利动机与公平偏好的权衡决定着个体拒绝或者接受不公平分配。根据双系统理论,对于个体拒绝不公平分配是系统1中的自动反应还是系统2中的控制加工这一争议,从理论假说、影响因素和脑机制三个方面进行了探讨。自动消极互惠假说和社会启发假说支持公平偏好的自动加工假说,公平偏好控制假说则认为公平偏好是抑制自利动机的控制加工的结果。系统1通过脑岛、杏仁核和腹内侧前额叶皮层识别和评估公平行为;系统2通过扣带回皮层、腹外侧、背内侧和背外侧前额叶皮层,对系统1进行重新评估和调节并做出相应的决策。个体差异因素和实验任务特征可能会影响个体在系统1中的自动反应。未来研究需要进一步完善实验范式,深入探索其中的调节变量及其神经网络。     

药物成瘾者决策缺陷的特征、机制及干预

药物成瘾者存在决策缺陷, 并表现出冲动性、风险寻求、奖赏失调、躯体内感信号缺失等特征。神经影像学研究表明药物滥用导致成瘾者背外侧前额皮层、前扣带回、眶额叶皮层、腹内侧前额皮层、杏仁核、脑岛等脑区受损, 这些损伤是引发其决策缺陷的主要原因。认知训练有利于提高个体的决策能力, 如目标管理训练和正念冥想等可以增强个体工作记忆、促进自我觉察和以目标为导向的行为; 而非侵入性脑刺激则可以直接改变与成瘾者决策相关脑区的激活状态, 从而提升与决策相关的认知功能。总体而言, 未来认知训练和非侵入性脑刺激在成瘾干预方面仍有广阔的拓展空间。     

认知重评和表达抑制情绪调节策略的脑网络分析：来自EEG和ERP的证据

本文旨在对认知重评和表达抑制两种常用情绪调节策略的自发脑网络特征及认知神经活动进行深入探讨。研究采集36名在校大学生的静息态和任务态脑电数据, 经过源定位和图论分析发现节点效率与两种情绪调节显著相关的脑区, 以及脑区之间的功能连接。研究结果表明, 在使用认知重评进行情绪调节时会激活前额叶皮质、前扣带回、顶叶、海马旁回和枕叶等多个脑区, 在使用表达抑制进行情绪调节时会激活前额叶皮质、顶叶、海马旁回、枕叶、颞叶和脑岛等多个脑区。因此, 这些脑区的节点效率或功能连接强度可能成为评估个体使用认知重评和表达抑制调节情绪效果的指标。     

公平行为的认知神经机制

大量研究采用最后通牒博弈发现人们愿意牺牲自身利益来维护公平,普遍具有不公平厌恶倾向。本文基于行为博弈任务对个体处于不同角色时的公平行为,从神经学层面做出新的解释,并对现存理论模型做了梳理。脑成像的研究发现,公平行为的相关脑区主要有负责情绪加工的脑岛和与认知控制相关的背外侧前额叶,内侧眶额皮层。前脑岛激活越大,个体拒绝不公平方案的可能性越大,而腹外侧前额叶可以调节前脑岛的活动,使个体采取更理性的方式,接受不公平分配方案。另外,睾酮素和催产素作为神经调节的激素,可以对公平行为起到调节作用,睾酮素通过抑制内侧眶额皮层的激活,增加对不公平方案的拒绝率,相反,催产素可以降低个体对于不公平方案的拒绝率,并增加个体的公平行为。     

公平规范执行中内群体偏爱的心理发展机制

如何揭示群体规范和公平价值在个体心理发展中的作用机理, 提升儿童-青少年在群际互动当中的公平感知与规范执行, 是教育心理领域的关键问题。公平规范执行中内群体偏爱现象是近年来的研究热点之一, 然而先前研究存在以下不足：1)大多采用问卷法, 易受社会赞许性的影响, 存在言行不一致的情况; 2)大多采用情景实验, 聚焦社会互动的最终行为输出端, 无法实时有效地把握社会决策的动态进程; 3)脑成像研究仍以fMRI技术为主, 侧重于评估认知加工潜在的脑区激活模式及各脑区间的功能连接, 缺乏对群际公平规范执行中大脑激活动态模式的精确把握。针对这些不足, 本项目从资产分配情景出发, 以儿童和青少年为研究对象, 联合运用认知、行为、眼动和电生理等多层次测评手段, 对公平规范执行中内群体偏爱的发生过程进行认知解析, 探讨认知控制和心智化在其间的关键作用机制及其心理发展轨迹。研究结果将服务于中小学管理中的德育教育, 引导与培养学生的公正感与行为。     

Response–effect compatibility of finger–numeral configurations in arithmetical context

Research in experimental economics suggests that decision making in strategic interactions is often guided by a concern for fairness. However, experimental economics studies routinely place participants of equal social status and no prior social history in anonymous interactions, a context that would tend to foster the adoption of an egalitarian fairness norm. Extensive research in anthropology (Fiske, 1991) and psychology (Bugental, 2000) suggests that social norms, including fairness norms, are relationship-specific, raising doubts about whether the concern for egalitarian fairness observed in the experimental economics literature would generalize to a wider range of social relations. In this paper we focus on an alternative social norm characteristic of hierarchical relationships: noblesse oblige—the obligation of high-ranking individuals to act honorably and beneficently towards subordinates. In a series of five experiments, we show that the norm of noblesse oblige predicts tolerance of free riding better than individual self-interest does.     

Are perceptions of fairness relationship-specific? The case of noblesse oblige

Research in experimental economics suggests that decision making in strategic interactions is often guided by a concern for fairness. However, experimental economics studies routinely place participants of equal social status and no prior social history in anonymous interactions, a context that would tend to foster the adoption of an egalitarian fairness norm.

Beyond Distributive Justice: The Reasonableness Norm in Chinese Reward Allocation

Western theorists have generally construed reward allocation as mainly a rational action by the notion that allocation decision-making is based solely on people's justice concern. We argued that reward allocation, as a social act taking place in a specific social-situational context, is influenced both by some social interactive factors such as the relationship and social interactions between the participants, and by the pervasive social norms governing people's conduct in a particular society. This study aimed at examining the influence of two such factors, guanxi (equivalent to relationship) and renqing (equivalent to human affect), on Chinese allocation decision-making under a distributive situation. We hypothesized that Chinese allocators would base their decision not only on their judgment of the participants' contributions but also on their guanxi with the participant. Specifically, we predicted that the emphasis on guanxi and renqing would be manifested in the Chinese allocator's employment of the reasonableness norm dictating that both reason ( li ) and affect ( qing ) are considered in making allocation decisions. To test this hypothesis, we adopted the scenario approach and asked subjects to hypothetically allocate a reward to one of six guanxi partners. The 228 participants were divided into six groups; in each group they were instructed to do the allocation based on one of the five norms respectively: fairness ( he li ), renqing , equity ( gong zheng ), "ought to," reasonableness ( he qing he li ), and to indicate what they "would" allocate. The findings confirmed that the reasonableness norm was the one which subjects adopted in reward allocation. The results were discussed in the context of Chinese culture.     

人工智能决策的公平感知

不平等问题是全球社会和经济发展需要应对的首要挑战, 也是实现全球可持续发展目标的核心障碍。人工智能(artificial intelligence, AI)为缓解不平等、促进社会公平提供了新的途径。然而, 新近研究发现, 即使客观上AI决策具有公平性和准确性, 个体仍可能对AI决策的公平感知较低。因此, 近年来越来越多的研究开始关注AI决策公平感知的影响因素。然而, 目前研究较为分散, 呈现出研究范式不统一、理论不清晰和机制未厘清等特征。这既不利于跨学科的研究对话, 也不利于研究者和实践者对AI决策公平感知形成系统性理解。基于此, 通过系统的梳理, 现有研究可以划分为两类: (1) AI单一决策的公平感知研究, 主要聚焦于AI特征和个体特征如何影响个体对AI决策的公平感知; (2) AI-人类二元决策的公平感知研究, 主要聚焦于对比个体对AI决策与人类决策公平感知的差异。在上述梳理基础上, 未来研究可以进一步探索AI决策公平感知的情绪影响机制等方向。     

心理学对经济学的涉入——从理性自利到社会偏好的决策框架

理性认知能力与社会偏好存在紧密的关联。文章简要回顾了经济决策理论从理性模型到有限理性模型和社会偏好模型的发展进程,论述了人们理性的局限性及其根源,并进一步探讨理性认知能力与社会偏好的关系。对人类以及灵长目动物的研究显示,有限理性可能是由根源于演化的适应性机制所导致。人类不公平厌恶的起源、个体公平能力的发展规律和表征公平的大脑结构上的证据表明,理性认知能力能让人更好地抑制自私性,实现更高层次的公平。     

大学生在社会困境中的公平决策:社会价值取向的影响

通过两项研究考查大学生在社会困境中的行为决策及公平感体验,检验社会价值取向的影响作用,有效被试分别为85名和84名。结果表明:(1)亲社会者比亲自我者更倾向做公平决策;信息对称比不对称条件更促进被试做公平决策;女生比男生更倾向做公平决策。(2)性别在社会价值取向与信息对称性对公平决策的影响中起调节作用,社会价值取向显著影响男生的公平决策,信息对称性显著影响女生的公平决策。(3)社会价值取向显著影响个体对不公平的容忍度,亲社会者更不容忍不公平行为。(4)对于利己的不公平行为,被试都倾向接受,亲社会者并不比亲自我者体验到更强的内疚情绪;对于不利己的不公平行为,被试都倾向拒绝,且产生较强的不公平感及气愤情绪。     

Preschoolers’ Compliance With Others’ Violations of Fairness Norms: The Roles of Intentionality and Affective Perspective Taking

ABSTRACT

Young children are remarkably compliant with social norms, especially those governing fairness and equality. Yet children also frequently observe and face opportunities to violate those social norms, particularly in situations in which doing so is self-beneficial. In 3 studies, we investigated the conditions under which children adhere to social norms using a novel resource distribution paradigm in which children met an experimenter who expressed either a norm-consistent (equal distribution) or norm-inconsistent (unequal distribution) intention. In Experiment 1, we found that preschoolers generally complied with an experimenter’s intention, regardless of its norm consistency. In Experiment 2, the experimenter again expressed a norm-consistent or norm-inconsistent intention but accidentally placed resources in the opposite distribution of that intended. Preschoolers mostly defaulted to the social norm of fairness. However, they were less likely to do so (and more likely to comply with the norm-violating experimenter) when the inequality was self-benefitting. The likelihood of norm defiance in the face of self-benefit appeared to relate to children’s affective perspective taking. In Experiment 3, we found that training preschoolers in affective perspective taking increased the likelihood children would defy a norm-violating experimenter’s unfair intention. Thus, although preschoolers were generally compliant, both fairness norms and affective perspective taking served as important mechanisms to help children selectively defy adults’ instructions and intentions.     

公平或是利益?权力对分配公平感的影响

通过3个实验逐步考察了高、低权力个体对三种分配方案(公平/劣势不公平/优势不公平)的公平感。结果发现：(1)被试的公平评级从高到低依次为公平、优势不公平、劣势不公平, 做出评级的反应时则从快到慢依次为公平、劣势不公平、优势不公平; (2)相对于低权力被试, 高权力被试对劣势不公平分配的公平评级更低, 而对公平分配和优势不公平分配的公平评级更高, 且做出公平判断的反应时更短。基于这些结果, 作者提出了公平与利益权衡的公平优先效应及权力的自我增强假设, 以更好地理解权力和公平的本质及二者的关系。     

Self-construal level and voice procedures: The individual self as psychological basis for procedural fairness effects

In the current article, we investigate the influence of self-construal level on procedural fairness effects, that is, the finding that fair versus unfair procedures influence people’s evaluations of their relation with decision-making authorities. In two experiments, we manipulated self-construal level by activating the individual self (“I”) or the social self (“We”), and we induced a control condition. Furthermore, we manipulated procedural fairness by granting versus denying participants an opportunity to voice their opinion in a decision-making process. Results consistently revealed stronger procedural fairness effects if the individual self is activated than if the social self is activated. It is concluded that sometimes the individual self, rather than the social self, constitutes the psychological basis for procedural fairness effects.
