There is an ever-increasing understanding of the cognitive mechanisms underlying how we process others’ behaviours during social interactions. However, little is known about how people decide when to leave an interaction. Are these decisions shaped by alternatives in the environment – the opportunity-costs of connecting to other people? Here, participants chose when to leave partners who treated them with varying degrees of fairness, and connect to others, in social environments with different opportunity-costs. Across four studies we find people leave partners more quickly when opportunity-costs are high, both the average fairness of people in the environment and the effort required to connect to another partner. People’s leaving times were accounted for by a fairness-adapted evidence accumulation model, and modulated by depression and loneliness scores. These findings demonstrate the computational processes underlying decisions to leave, and highlight atypical social time allocations as a marker of poor mental health. Across four experiments, participants chose to spend more time with partners who made fair offers; likewise, a poor social environment and low opportunity-costs led participants to stay with partners.
人们对我们在社会交往中如何处理他人行为的认知机制有了越来越多的了解。然而,人们对于如何决定何时离开互动却知之甚少。这些决定是由环境中的替代品--与他人建立联系的机会成本--决定的吗?在这里,参与者选择何时离开以不同程度的公平对待他们的伙伴,并在机会成本不同的社会环境中与其他人建立联系。在四项研究中,我们发现当机会成本(包括环境中人们的平均公平程度和与其他伙伴建立联系所需的努力)较高时,人们会更快地离开伙伴。人们离开伴侣的时间是由一个公平性适应的证据积累模型来解释的,并受到抑郁和孤独评分的调节。这些发现证明了决定离开的计算过程,并强调了非典型社交时间分配是心理健康状况不佳的标志。在四项实验中,参与者选择花更多时间与提供公平条件的伙伴在一起;同样,糟糕的社交环境和低机会成本也会导致参与者留在伙伴身边。

The term polarization is used to describe both the division of a society into opposing groups (political polarization), and a social psychological phenomenon (group polarization) whereby people adopt more extreme positions after discussion. We explain how group polarization underpins the political polarization phenomenon: Social interaction, for example through social media, enables groups to form in such a way that their beliefs about what should be done to change the world—and how this differs from the stance of other groups—become integrated as aspects of a new, shared social identity. This provides a basis for mobilization to collective action. Group polarization, a result of social interaction, can underpin political polarization—the division of society into groups. While intergroup conflict and hostility are possible outcomes of polarization, polarization as a mobilizing force for collective action can benefit marginalized groups.
两极分化一词既指社会被划分为对立的群体(政治极化),也指一种社会心理现象(群体极化),即人们在讨论后采取更极端的立场。我们将解释群体极化如何成为政治极化现象的基础:社会互动(例如通过社交媒体)使群体得以形成,从而使他们关于应该采取哪些措施来改变世界的信念--以及这些信念与其他群体立场的不同之处--整合为一种新的、共同的社会认同。这就为动员起来采取集体行动奠定了基础。群体极化是社会互动的结果,也是政治极化--将社会划分为不同群体--的基础。虽然群体间的冲突和敌意是两极分化的可能结果,但两极分化作为集体行动的动员力量,可以使边缘化群体受益。

The word zeitgeist refers to common perceptions shared in a given culture. Meanwhile, a defining feature of loneliness is feeling that one’s views are not shared with others. Does loneliness correspond with deviating from the zeitgeist? Across two independent brain imaging datasets, lonely participants’ neural representations of well-known celebrities strayed from group-consensus neural representations in the medial prefrontal cortex—a region that encodes and retrieves social knowledge (Studies 1 A/1B: N = 40 each). Because communication fosters social connection by creating shared reality, we next asked whether lonelier participants’ communication about well-known celebrities also deviates from the zeitgeist. Indeed, when a strong group consensus exists, lonelier individuals use idiosyncratic language to describe well-known celebrities (Study 2: N = 923). Collectively, results support lonely individuals’ feeling that their views are not shared. This suggests loneliness may not only reflect impoverished relationships with specific individuals, but also feelings of disconnection from prevalently shared views of contemporary culture. Written descriptions and neural activity indicate that lonelier individuals’ semantic and neural representations of contemporary cultural figures depart more from the group-consensus when compared to less lonely individuals.
时代精神(zeitgeist)一词指的是特定文化中的共同观念。与此同时,孤独感的一个显著特点就是觉得自己的观点不被他人认同。孤独是否与偏离时代潮流相对应?在两个独立的大脑成像数据集中,孤独参与者对知名名人的神经表征偏离了内侧前额叶皮层--一个编码和检索社会知识的区域--的群体共识神经表征(研究1 A/1B:N = 40)。因为交流通过创造共同的现实促进了社会联系,所以我们接下来要问的是,较孤独的参与者关于知名名人的交流是否也偏离了时代潮流。事实上,当群体存在强烈共识时,孤独者会使用特异的语言来描述知名名人(研究 2:N = 923)。总之,研究结果支持了孤独者的观点不被认同的感觉。这表明,孤独不仅反映了与特定个体之间的关系不融洽,还反映了与当代文化的普遍共识脱节的感觉。书面描述和神经活动表明,与不那么孤独的个体相比,孤独个体对当代文化人物的语义和神经表征更偏离群体共识。

Imagined otherness fuels blatant dehumanization of outgroups 想象中的 "异类 "助长了对外部群体的公然非人化

Dehumanization of others has been attributed to institutional processes that spread dehumanizing norms and narratives, as well as to individuals’ denial of mind to others. We propose that blatant dehumanization also arises when people actively contemplate others’ minds. We introduce the construct of imagined otherness—perceiving that a prototypical member of a social group construes an important facet of the social world in ways that diverge from the way most humans understand it—and argue that such attributions catalyze blatant dehumanization beyond the effects of general perceived difference and group identification. Measuring perceived schematic difference relative to the concept of America, we examine how this measure relates to the tendency of U.S. Republicans and Democrats to blatantly dehumanize members of the other political party. We report the results of two pre-registered studies—one correlational (N = 771) and one experimental (N = 398)—that together lend support for our theory. We discuss implications of these findings for research on social boundaries, political polarization, and the measurement of meaning. Perceiving outgroup members as holding different schematic understandings of the concept of America as compared to most other people is associated with greater dehumanization of outgroup members
对他人的非人性化归因于传播非人性化规范和叙事的制度过程,以及个人对他人思想的否定。我们提出,当人们主动思考他人的思想时,也会产生公然的非人化。我们引入了 "想象中的他者 "这一概念--认为社会群体中的原型成员对社会世界某一重要方面的理解与大多数人的理解不同--并论证了这种归因催化了公然的非人化,超越了一般感知差异和群体认同的影响。我们测量了相对于 "美国 "概念的感知图式差异,研究了这一测量与美国共和党和民主党公然将另一政党成员非人化的倾向之间的关系。我们报告了两项预先登记的研究结果--一项是相关研究(771 人),另一项是实验研究(398 人)--这两项研究共同支持了我们的理论。我们将讨论这些研究结果对社会界限、政治极化和意义测量研究的影响。与大多数其他人相比,认为外群体成员对 "美国 "概念持有不同的图式理解与外群体成员更多的非人性化相关联

The footprint of the legal system in the United States is expansive. Applying psychological and neuroscience research to understand or predict individual criminal behavior is problematic. Nonetheless, psychology and neuroscience can contribute substantially to the betterment of the criminal legal system and the outcomes it produces. We argue that scientific findings should be applied to the legal system through systemwide policy changes. Specifically, we discuss how science can shape policies around pollution in prisons, the use of solitary confinement, and the law’s conceptualization of insanity. Policies informed by psychology and neuroscience have the potential to affect meaningful—and much-needed—legal change. This Perspective calls for a reform of the criminal justice system in the US. Psychological and neuroscientific research should inform regulations around pollution and toxins, policies for solitary confinement, and the framework for the admissibility of legal insanity defense.
美国法律系统的覆盖面很广。应用心理学和神经科学研究来理解或预测个人犯罪行为是有问题的。然而,心理学和神经科学可以为改善刑事法律系统及其产生的结果做出重大贡献。我们认为,应通过全系统的政策变革将科学发现应用于法律体系。具体而言,我们讨论了科学如何塑造有关监狱污染、单独监禁的使用以及法律对精神错乱的概念化的政策。以心理学和神经科学为依据的政策有可能影响有意义的--而且是亟需的--法律变革。本视角呼吁改革美国的刑事司法系统。心理学和神经科学研究应为有关污染和毒素的法规、单独监禁政策以及精神错乱法律辩护的可接受性框架提供信息。

Witnessing another’s pain can heighten pain in the observer. However, research has focused on the observer’s intrapersonal experience. Here, a social transmission-chain explored the spread of socially-acquired nocebo hyperalgesia. Dyads of genuine participants were randomised to ‘Generations’ (G1–G3). G1-Demonstrators, observed by G2-Observers, experienced high/low thermal pain contingent on supposed activity/inactivity of a sham-treatment. G2 became Demonstrators, witnessed by G3-Observers. They experienced fixed low-temperature stimuli irrespective of sham-treatment ‘activity’. G3 then Demonstrated for G4-Observers (a confederate), also experiencing low-temperature stimuli only. Pain ratings, electrodermal activity, and facial action units were measured. G1’s treatment-related pain propagated throughout the chain. G2 and G3 participants showed heightened subjective and physiological response to sham-treatment, despite equivalent stimulus temperatures, and G3 never witnessing the initial pain-event. Dyadic interpersonal physiological synchrony (electrodermal activity) and psychological synchrony (Observer’s ability to predict the Demonstrator’s pain), predicted subsequent socially-acquired pain. Implications relate to the interpersonal spread of maladaptive pain experiences. Nocebo hyperalgesia can be socially transmitted through a chain of observers. Differences in interpersonal physiological and psychological synchrony predicted subsequent socially-acquired pain.
目睹他人的痛苦会加剧观察者的痛苦。然而,研究主要集中在观察者的个人体验上。在这里,我们通过社会传播链来探索社会获得的 "预兆痛觉 "的传播。由真实参与者组成的二人组被随机分配到 "世代"(G1-G3)中。G1-演示者在 G2-观察者的观察下,根据假治疗的假定活动/活动性体验高/低热痛。G2 成为示范者,由 G3 观察者见证。他们体验到固定的低温刺激,与假治疗的 "活动 "无关。然后,G3 为 G4 观察者(一名同伴)演示,同样只体验低温刺激。对疼痛评分、皮肤电活动和面部动作单位进行了测量。G1 的治疗相关疼痛在整个链条中传播。G2 和 G3 参与者对假治疗表现出更强烈的主观和生理反应,尽管刺激温度相当,而且 G3 从未目睹最初的疼痛事件。人际间的生理同步性(皮肤电活动)和心理同步性(观察者预测示范者疼痛的能力)可预测随后的社交性疼痛。这对适应不良疼痛体验的人际传播具有重要意义。过度痛觉可以通过一连串的观察者在社会上传播。人际间生理和心理同步性的差异可预测随后的社交性疼痛。

Distractor inhibition by alpha oscillations is controlled by an indirect mechanism governed by goal-relevant information 阿尔法振荡的分心抑制是由目标相关信息的间接机制控制的

The role of alpha oscillations (8–13 Hz) in cognition is intensively investigated. While intracranial animal recordings demonstrate that alpha oscillations are associated with decreased neuronal excitability, it is been questioned whether alpha oscillations are under direct control from frontoparietal areas to suppress visual distractors. We here point to a revised mechanism in which alpha oscillations are controlled by an indirect mechanism governed by the load of goal-relevant information – a view compatible with perceptual load theory. We will outline how this framework can be further tested and discuss the consequences for network dynamics and resource allocation in the working brain. This Perspective argues for a revised mechanism for the functional role of alpha oscillations. While alpha oscillations reflect inhibition, they are controlled by an indirect mechanism governed by the load of goal-relevant information.
α振荡(8-13赫兹)在认知中的作用受到了深入研究。虽然颅内动物记录表明阿尔法振荡与神经元兴奋性降低有关,但阿尔法振荡是否受额顶叶区域的直接控制以抑制视觉干扰因素却受到质疑。我们在此指出了一种经过修正的机制,即阿尔法振荡受目标相关信息负荷的间接机制控制--这种观点与知觉负荷理论相一致。我们将概述如何进一步检验这一框架,并讨论其对工作脑中网络动力学和资源分配的影响。本视角论证了阿尔法振荡功能作用的修正机制。虽然α振荡反映了抑制作用,但它是由目标相关信息负荷的间接机制控制的。

Thermal contrast enhancement predicts paradoxical heat sensation 热对比增强可预测矛盾热感

Paradoxical Heat Sensation (PHS) is the remarkable feeling of warmth or heat pain while the skin is cooling. Despite its initial documentation over 100 years ago, a unified explanation for this perplexing experience remains elusive. Here we apply contrast enhancement principles, known for their instrumental role in understanding visual illusions, to the domain of thermosensation. Contrast enhancement describes the amplification of two contrasting visual features, such as the enhanced perception of an edge between a light and dark bar. In thermosensation, this encompasses an enhancement of the difference between sequential warming and cooling of the skin, and is defined as the normalised difference between successive temporal warm and cold temperatures. Remarkably, thermal contrast predicts the occurrence of PHS. Our findings reveal compelling evidence supporting the role of thermal contrast in the generation of PHS, shedding light on its underlying mechanism and offering a framework for broader encoding principles in thermosensation and pain. Applying contrast enhancement principles, established within the visual and auditory domain, to thermosensation, reveals that larger temporal contrasts increase the probability of experiencing thermal nociceptive illusions.
反常热感(PHS)是指在皮肤冷却时却有明显的发热或热痛感觉。尽管早在 100 多年前就有文献记载了这种令人困惑的体验,但至今仍未找到统一的解释。在此,我们将对比度增强原理应用于热感觉领域,该原理因其在理解视觉错觉方面的重要作用而闻名。对比增强描述的是两种对比强烈的视觉特征的放大,例如明暗条纹之间的边缘感知增强。在热感觉中,这包括皮肤连续升温和降温之间差异的增强,并被定义为连续时间性冷热温度之间的归一化差异。值得注意的是,热对比能预测 PHS 的发生。我们的研究结果揭示了令人信服的证据,支持热对比在 PHS 发生中的作用,揭示了其潜在机制,并为热感觉和疼痛中更广泛的编码原理提供了一个框架。将在视觉和听觉领域建立的对比度增强原理应用于热感觉,可以发现较大的时间对比度会增加出现热痛觉幻觉的概率。

Despite its initial documentation over 100 years ago, a unified explanation for this perplexing experience remains elusive. Here we apply contrast enhancement principles, known for their instrumental role in understanding visual illusions, to the domain of thermosensation. Contrast enhancement describes the amplification of two contrasting visual features, such as the enhanced perception of an edge between a light and dark bar. In thermosensation, this encompasses an enhancement of the difference between sequential warming and cooling of the skin, and is defined as the normalised difference between successive temporal warm and cold temperatures.

People are surprisingly hesitant to reach out to old friends 人们在联系老朋友时出奇地犹豫不决

Social relationships provide one of the most reliable paths to happiness, but relationships can fade for various reasons. While it does not take much to reinitiate contact, here we find that people are surprisingly reluctant to do so. Specifically, most people reported losing touch with an old friend yet expressed little interest in reaching out (Studies 1-2, Ns = 401 and 199). Moreover, fewer than one third of participants sent a message to an old friend, even when they wanted to, thought the friend would be appreciative, had the friend’s contact information, and were given time to draft and send a message (Studies 3-4, Ns = 453 and 604). One reason for this reluctance may be that old friends feel like strangers. Supporting this possibility, participants were no more willing to reach out to an old friend than they were to talk to a stranger (Study 5, N = 288), and were less willing to contact old friends who felt more like strangers (Study 6, N = 319). Therefore, in Study 7 (N = 194), we adapted an intervention shown to ease anxieties about talking to strangers and found that it increased the number of people who reached out to an old friend by two-thirds. Individuals seldom reach out to old friends with whom they have lost touch. Interventions focused on changing attitudes were ineffective, but practicing reaching out to current friends first successfully encouraged people to reach out to old friends.
社会关系是通往幸福的最可靠途径之一,但由于种种原因,人际关系可能会淡化。虽然重新建立联系并不需要花费太多时间,但我们发现人们却出人意料地不愿意这样做。具体来说,大多数人表示与老朋友失去了联系,但却没有兴趣主动联系(研究 1-2,人数 = 401 和 199)。此外,只有不到三分之一的参与者向老朋友发送了信息,即使他们想这样做,认为朋友会感激他们,有朋友的联系方式,并且有时间起草和发送信息(研究 3-4,人数 = 453 和 604)。这种不情愿的原因之一可能是老朋友给人的感觉就像陌生人。为了证实这种可能性,参与者主动联系老朋友的意愿并不比与陌生人交谈的意愿高(研究 5,人数 = 288),而且他们更不愿意联系感觉更像陌生人的老朋友(研究 6,人数 = 319)。因此,在研究 7(N = 194)中,我们调整了一项干预措施,该措施被证明可以缓解与陌生人交谈时的焦虑,结果发现该措施使主动联系老朋友的人数增加了三分之二。人们很少主动联系失去联系的老朋友。以改变态度为重点的干预措施效果不佳,但先与现在的朋友联系的做法成功地鼓励了人们与老朋友联系。
