The four elementary forms of sociality: framework for a unified theory of social relations

A framework for studying the conceptual structure of human relationships

How does the mind represent the structure of human relationships? In a recent article, Cheng et al. address this with an interdisciplinary approach combining principal component analysis (PCA), large-scale data collection of human ratings from diverse cultures, and Large Language Model (LLM)-based analyses of historical texts. They reveal a robust 5D framework and three core categories of relationships.

Message source effects on rejection and costly punishment of criticism across cultures

Subgroups of societies evaluate information differently, leading to partisan polarization and societal rifts world-wide. Beyond mere disagreement about facts or different preferences, we identify a group-based mechanism predicting the rejection of critical messages and costly punishment of the commenter across three previously understudied and representative cultures. Our pre-registration was peer-reviewed within the Leibniz-Institute for Psychology lab-track scheme prior to data collection and, once accepted, funded. Participants (N = 2207) from China (collectivism, n = 786), Canada (individualism, n = 666), and Japan (honor, n = 755) consistently rejected criticism of their own national group that was attributed to a source from a different national group (intergroup criticism), as compared to the same criticism from within their group. These intergroup sensitivity effects were larger in China than in Canada or Japan. In Canada and Japan only, a bystander intergroup sensitivity effect emerged such that participants rejected criticism of another national group (i.e., they do not belong to) that was attributed to a source from a different national group (intergroup criticism), as compared to the same criticism from within that group. Apparently, the processes underlying this robust effect differ between cultures. We conclude that group-based message rejection contributes to societal rifts in many different cultures.

Maintaining cooperation through vertical communication of trust when removing sanctions

An effective way to foster cooperation is to monitor behavior and sanction freeriding. Yet, previous studies have shown that cooperation quickly declines when sanctioning mechanisms are removed. We test whether explicitly expressing trust in players' capability to maintain cooperation after the removal of sanctions, i.e., vertical communication of trust, has the potential to alleviate this drop in compliance. Four incentivized public-goods experiments (N = 2,823) find that the vertical communication of trust maintains cooperation upon the removal of centralized (Study 1), third-party (Study 2a, 2b), and peer punishment (Study 3), and this effect extends beyond single interactions (Study 4). In all studies, vertical trust communication increases mutual trust among players, providing support to the idea that vertically communicating trust can be a self-fulfilling prophecy. Extrapolating our findings to natural environments, they suggest that authorities should carefully consider how they communicate the lifting of rules and sanctions.

The conceptual structure of human relationships across modern and historical cultures

A defining characteristic of social complexity in Homo sapiens is the diversity of our relationships. We build connections of various types in our families, workplaces, neighbourhoods and online communities. How do we make sense of such complex systems of human relationships? The basic organization of relationships has long been studied in the social sciences, but no consensus has been reached. Here, by using online surveys, laboratory cognitive tasks and natural language processing in diverse modern cultures across the world (n = 20,427) and ancient cultures spanning 3,000 years of history, we examined universality and cultural variability in the ways that people conceptualize relationships. We discovered a universal representational space for relationship concepts, comprising five principal dimensions (formality, activeness, valence, exchange and equality) and three core categories (hostile, public and private relationships). Our work reveals the fundamental cognitive constructs and cultural principles of human relationship knowledge and advances our understanding of human sociality.

Why friendship and loneliness affect our health

Humans, like all monkeys and apes, have an intense desire to be social. The human social world, however, is extraordinarily complex, depends on sophisticated cognitive and neural processing, and is easily destabilized, with dramatic consequences for our mental and physical health. To show why, I first summarize descriptive aspects of human friendships and what they do for us, then discuss the cognitive and neurobiological processes that underpin them. I then summarize the growing body of evidence suggesting that our mental as well as our physical health and wellbeing are best predicted by the number and quality of close friend/family relationships we have, with five being the optimal number. Finally, I review neurobiological evidence that both number of friends and loneliness itself are correlated with the volume of certain key brain regions associated with the default mode neural network and its associated gray-matter processing units.

Seeking Communal Emotions in Social Practices That Culturally Evolved to Evoke Emotions: Worship, Kitten Videos, Memorials, Narratives of Love, and More

In many instances, emotions do not simply happen to people by chance. Often, people actively seek out an emotion by engaging in practices that have culturally evolved to evoke that emotion. Such practices tend to be perpetuated and spread if people want to experience the emotion, like to recall it and tell others about it, want to give the emotion to others and experience it together, and/or regard the emotion as a sign of something wonderful. We illustrate this with a newly delineated emotion, kama muta. Many social practices around the world are structured to evoke kama muta. In those culturally evolved practices, and outside them, what typically evokes kama muta is a sudden intensification of communal sharing, or a sudden shift of attention to a communal sharing relationship. It seems probable that other social-relational emotions are also evoked by sudden changes in relationships or the sudden salience of a relationship. This change or saliencing may be incorporated in social practices that are perpetuated because they evoke the sought-after emotion. We suggest that such practices, as well as sudden changes in relationships that occur elsewhere, are especially promising places to discover social-relational emotions.

What Can we Learn About Human Nature from Interacting with Strangers? Relationship Type Determines Behavior in the Dictator Game

Behavioral decision-making research has been exceptionally useful in the quest of the social sciences to understand human nature. A frequent assumption of this research is that using strangers as anonymous interaction partners allows for the clearest demonstration of basic human nature. But a diverse array of literature - from social and clinical psychology to ethology - suggests that a stranger is far from a "baseline partner." We argue against the overreliance on strangers in economic games and that instead of one baseline partner, typical relationships should fall into basic types of partners, all eliciting different behaviors. Two high-powered experiments (Ns = 848 and 2400) in which participants played a hypothetical dictator game with one of sixteen partners (e.g., mother, friend, stranger) found particular clusters of interaction partners in which the possible partners were grouped into different and intuitively meaningful relationship types (i.e., loved ones, intimate partners, companions, contractual partners, infrahumanized others). The clusters suggest a typology of basic human relationships and predict behavior even when controlling for relationship distance. The findings help to calibrate the outcomes of past dictator games utilizing strangers and offer an interpretative context with a system of relationship types.

Is in-kind kinder than cash? The impact of money vs. food aid on social emotions and aid take-up

Over the past decade, there has been a shift in the way charities deliver humanitarian aid. Historically, the most prevalent way to help the global poor was by providing in-kind asset transfers. Recently, alternatives to in-kind aid, such as cash aid, have been increasing in prevalence. Although there has been widespread endorsement from the academic community and the public on the popularizing model of giving cash aid, one perspective remains untouched: the recipient's perspective. Thus, the present research explores how food-insecure individuals feel when receiving money vs. in-kind food aid to help meet their hunger and nutrition needs. Specifically, we explore the degree of positive (e.g., feeling cared for) and negative (e.g., feeling ashamed) social emotions felt when receiving the aid opportunity and how willing recipients are to accept monetary (vs. food) aid. Results from five preregistered experiments (N = 3,110)-a field experiment in Kenya and four online experiments in the United States-find that monetary (vs. food) aid elicits comparatively more of a market-pricing relationship and less of a communal sharing relationship and, hence, makes people feel less positive and more negative social emotions when receiving the help. Subsequently, recipients are less likely to take up monetary (vs. food) aid from a charity. However, we find that this effect does not persist when receiving government aid: Recipients are similarly willing to accept money and in-kind food aid from the government. This research suggests that future scholarship ought to examine ways to improve psychological experiences when receiving money from charity.

How infants predict respect-based power

Research has shown that infants represent legitimate leadership and predict continued obedience to authority, but which cues they use to do so remains unknown. Across eight pre-registered experiments varying the cue provided, we tested if Norwegian 21-month-olds (N=128) expected three protagonists to obey a character even in her absence. We assessed whether bowing for the character, receiving a tribute from or conferring a benefit to the protagonists, imposing a cost on them (forcefully taking a resource or hitting them), or relative physical size were used as cues to generate the expectation of continued obedience that marks legitimate leadership. Whereas bowing sufficed in generating such an expectation, we found positive Bayesian evidence that all the other cues did not. Norwegian infants unlikely have witnessed bowing in their everyday life. Hence, bowing/prostration as cue for continued obedience may form part of an early-developing capacity to represent leadership built by evolution.

Red Backgrounds Enhance Dominance in Human Faces and Shapes

Red color signals dominance in both animals and humans. This study investigated whether a red background color influences the perception of dominance in human faces and geometric shapes. The facial stimuli consisted of computer-generated faces, quantitatively morphed into nine levels of dominance, ranging from less dominant to more dominant. This included East-Asian female faces in Experiment 1 and male faces in Experiment 2. The face stimuli were presented against three background colors: red, green, and gray. Participants were instructed to categorize the faces as either obedient or dominant by pressing the corresponding labeled keys. The results showed that faces were more likely to be perceived as dominant when presented against a red background than against green or gray backgrounds, for both female and male faces. Additionally, two questionnaire surveys showed that the perception of dominance also increased for shapes presented against a red background. However the effect of red diminished in the absence of the actual perception of the color red. These results suggest that the perception of dominance in both human faces and objects is enhanced by the presence of red, possibly due to evolutionary factors related to the perception of red.

Questioning the nature and origins of the "social agent" concept

Spelke posits that the concept of "social agent," who performs object-directed actions to fulfill social goals, is the first noncore concept that infants acquire as they begin to learn their native language. We question this proposal on empirical grounds and theoretical grounds, and propose instead that the representation of object-mediated interactions may be supported by a dedicated prelinguistic mechanism.

The Representation of Giving Actions: Event Construction in the Service of Monitoring Social Relationships

Giving is a unique attribute of human sharing. In this review, we discuss evidence attesting to our species' preparedness to recognize interactions based on this behavior. We show that infants and adults require minimal cues of resource transfer to relate the participants of a giving event in an interactive unit (A gives X to B) and that such an interpretation does not systematically generalize to superficially similar taking events, which may be interpreted in nonsocial terms (A takes X). We argue that this asymmetry, echoed in language, reveals the operations of a mechanism of event construction where participant roles are encoded only when they are crucial to rendering an action teleologically well-formed. We show that such a representation of giving allows people to monitor the direction (who gave to whom) and kind (what was given) of resource transfer within a dyad, suggesting that giving may be interpreted as indicative of a relationship based on long-term balance. As this research suggests, advancing the study of the prelinguistic representation of giving has implications for cognitive linguistics, by clarifying the relation between event participants and syntactic arguments, as well as social cognition, by identifying which kinds of relational inferences people draw from attending to acts of sharing.

Secret disclosure and social relationships in groups

Personal secrets are a ubiquitous fact of group life, but the conditions under which they are revealed have not been explored. In five studies, we assessed secret disclosure in groups governed by four models of human sociality (Communal Sharing, Equality Matching, Authority Ranking, Market Pricing; Fiske). In Studies 1a and 1b, participants indicated their willingness to disclose secrets in hypothetical groups governed by the models. In Studies 2a and 2b, participants rated how much a group in which they disclosed secrets or nonsecrets is governed by the models. In Study 3, participants indicated their disclosure of various types of secrets in Communal Sharing and Equality Matching groups to which they belonged. Across studies, disclosure was most strongly associated with Communal Sharing, followed by Equality Matching. Study 3 further showed that identity fusion predicted disclosure in these two kinds of groups. Implications for understanding disclosure of personal secrets in group contexts were discussed.

The Intergroup Value Protection Model: A Theoretically Integrative and Dynamic Approach to Intergroup Conflict Escalation in Democratic Societies

SCIENTIFIC ABSTRACT

We review social-psychological evidence for a theoretically integrative and dynamic model of intergroup conflict escalation within democratic societies. Viewing individuals as social regulators who protect their social embeddedness (e.g., in their group or in society), the intergroup value protection model (IVPM) integrates key insights and concepts from moral and group psychology (e.g., group identification, outrage, moralization, protest) into a functional intergroup value protection process. The model assumes that social regulators are continuously looking for information diagnostic of the outgroup's intentions to terminate the relationship with the ingroup, and that their specific cognitive interpretations of an outgroup's action (i.e., as a violation of ingroup or shared values) trigger this process. The visible value-protective responses of one group can trigger the other group's value-protective responses, thus dynamically increasing chances of conflict escalation. We discuss scientific implications of integrating moral and group psychology and practical challenges for managing intergroup conflict within democratic societies.

PUBLIC ABSTRACT

The 2021 Capitol Hill attack exemplifies a major "trigger event" for different groups to protect their values within a democratic society. Which specific perceptions generate such a triggering event, which value-protective responses does it trigger, and do such responses escalate intergroup conflict? We offer the intergroup value protection model to analyze the moral and group psychology of intergroup conflict escalation in democratic societies. It predicts that when group members cognitively interpret another group's actions as violating ingroup or shared values, this triggers the intergroup value protection process (e.g., increased ingroup identification, outrage, moralization, social protest). When such value-protective responses are visible to the outgroup, this can in turn constitute a trigger event for them to protect their values, thus increasing chances of intergroup conflict escalation. We discuss scientific implications and practical challenges for managing intergroup value conflict in democratic societies, including fears of societal breakdown and scope for social change.

Infants Infer Social Relationships Between Individuals Who Engage in Imitative Social Interactions

Infants are born into rich social networks and are faced with the challenge of learning about them. When infants observe social interactions, they make predictions about future behavior, but it is not clear whether these predictions are based on social dispositions, social relationships, or both. The current studies (N = 188, N = 90 males) address this question in 12-month-old infants and 16- to 18-month-old toddlers who observe social interactions involving imitation. In Studies 1 and 3, infants and toddlers expected that imitators, compared to non-imitators, would respond to their social partners' distress. Likewise, they expected the targets of imitation, compared to non-targets, to respond to their partner's distress. In Study 2, these expectations did not generalize to interactions with a new partner, providing evidence that infants learned about the relationships between individuals as opposed to their dispositions. In Study 3, infants did not make predictions about responses to laughter, suggesting that infants see imitation as indicative of a specific kind of social relationship. Together, these results provide evidence that imitative interactions support infants' and toddlers' learning about the social relationships connecting unknown individuals.

The Norm of Reciprocity in Intergroup Context: A Normative-Identity Model

Reciprocity, regarded as a fundamental psychological phenomenon, may underlie a wide range of interpersonal and intergroup behaviors. Various disciplines such as behavioral economics, anthropology, sociology, and psychology as well documented how reciprocity is a strong determinant of human behavior. On the other hand, less is known about intergroup reciprocity, its functions and consequences as well as the psychological mechanisms through which these effects manifest, remain mostly unknown. In this paper, we propose a model to understand how the reciprocity norm operates in the intergroup contexts, through employing the Personal Norm of Reciprocity model (Perugini et al., 2003) and the Self-Categorization Theory (Turner et al., 1987). We suggest that the conditions that give rise to intergroup reciprocal behavior are ingroup identification, labeling outgroup behavior as a favor or transgression, and the internalization of the reciprocity norm. We also propose that the intergroup outcomes, such as ingroup favoritism, discrimination, collective action, and conflict resolution, might become more understandable when taking into account the reciprocity as an explanatory variable.

Self- and Other-Orientation in High Rank: A Cultural Psychological Approach to Social Hierarchy

PUBLIC ABSTRACT

Social hierarchy is one fundamental aspect of human life, structuring interactions in families, teams, and entire societies. In this review, we put forward a new theory about how social hierarchy is shaped by the wider societal contexts (i.e., cultures). Comparing East Asian and Western cultural contexts, we show how culture comprises societal beliefs about who can raise to high rank (e.g., become a leader), shapes interactions between high- and low-ranking individuals (e.g., in a team), and influences human thought and behavior in social hierarchies. Overall, we find cultural similarities, in that high-ranking individuals are agentic and self-oriented in both cultural contexts. But we also find important cross-cultural differences. In East Asian cultural contexts, high-ranking individuals are also other oriented; they are also concerned about the people around them and their relationships. We close with a call to action, suggesting studying social hierarchies in more diverse cultural contexts.

The psychological, computational, and neural foundations of indebtedness

Receiving a favor from another person may induce a negative feeling of indebtedness for the beneficiary. In this study, we explore these hidden costs by developing and validating a conceptual model of indebtedness across three studies that combine a large-scale online questionnaire, an interpersonal game, computational modeling, and neuroimaging. Our model captures how individuals perceive the altruistic and strategic intentions of the benefactor. These inferences produce distinct feelings of guilt and obligation that together comprise indebtedness and motivate reciprocity. Perceived altruistic intentions convey care and communal concern and are associated with activity in insula, ventromedial prefrontal cortex and dorsolateral prefrontal cortex, while inferred strategic intentions convey expectations of future reciprocity and are associated with activation in temporal parietal junction and dorsomedial prefrontal cortex. We further develop a neural utility model of indebtedness using multivariate patterns of brain activity that captures the tradeoff between these feelings and reliably predicts reciprocity behavior.

Reading minds or reading scripts? De-intellectualising theory of mind

Understanding the origins of human social cognition is a central challenge in contemporary science. In recent decades, the idea of a 'Theory of Mind' (ToM) has emerged as the most popular way of explaining unique features of human social cognition. This default view has been progressively undermined by research on 'implicit' ToM, which suggests that relevant precursor abilities may already be present in preverbal human infants and great apes. However, this area of research suffers from conceptual difficulties and empirical limitations, including explanatory circularity, over-intellectualisation, and inconsistent empirical replication. Our article breaks new ground by adapting 'script theory' for application to both linguistic and non-linguistic agents. It thereby provides a new theoretical framework able to resolve the aforementioned issues, generate novel predictions, and provide a plausible account of how individuals make sense of the behaviour of others. Script theory is based on the premise that pre-verbal infants and great apes are capable of basic forms of agency-detection and non-mentalistic goal understanding, allowing individuals to form event-schemata that are then used to make sense of the behaviour of others. We show how script theory circumvents fundamental problems created by ToM-based frameworks, explains patterns of inconsistent replication, and offers important novel predictions regarding how humans and other animals understand and predict the behaviour of others.

Uncovering the underlying factors of ERP changes in the cyberball paradigm: A systematic review investigating the impact of ostracism and paradigm characteristics

The Cyberball is the most commonly employed paradigm for the investigation of the effects of social exclusion, also called ostracism. The analysis of event-related potentials (ERPs), short-term stimulus-induced fluctuations in the EEG signal, has been employed for the identification of time-sensitive neural responses to ostracism-related information. Changes in ERPs during the Cyberball are normally attributed to the effect of ostracism, but it has been argued that characteristics of the paradigm, not ostracism, are the driving force for these changes. To elucidate the origin of the ERP changes in the Cyberball, we systematically reviewed the Cyberball-ERP literature of healthy, adult populations, and evaluated whether the social context of ostracism or characteristics of the paradigm are better suited for the explanation of the found results. Our results show that for many components no clear origin can be identified, but that expectancy violations, not ostracism, best explains the results of the P3 complex. Future research should therefore also employ other paradigms for the research into the effects of ostracism on ERPs.

Improving the acceptability of social robots: Make them look different from humans

The social robots market will grow considerably in the coming years. What the arrival of these new kind of social agents means for society, however, is largely unknown. Existing cases of robot abuse point to risks of introducing such artificial social agents (ASAs) without considerations about consequences (risks for the robots and the human witnesses to the abuse). We believe that humans react aggressively towards ASAs when they are enticed into establishing dominance hierarchies. This happens when there is a basis for skill comparison. We therefore presented pairs of robots on which we varied similarity and the degree of stimulatability of their mechanisms/functions with the human body (walking, jumping = simulatable; rolling, floating = non-simulatable). We asked which robot (i) resembled more a human, (ii) possessed more "essentialized human qualities" (e.g. creativity). To estimate social acceptability, participants had also (iii) to predict the outcome of a situation where a robot approached a group of humans. For robots with simulatable functions, rating of essentialized human qualities decreased as human resemblance decreased (jumper < walker). For robots with non-simulable functions, the reversed relation was seen: robots that least resembled humans (floater) scored highest in qualities. Critically, robot's acceptability followed ratings of essentialized human qualities. Humans respond socially to certain morphological (physical aspects) and behavioral cues. Therefore, unless ASAs perfectly mimic humans, it is safer to provide them with mechanisms/functions that cannot be simulated with the human body.

Why We Gather: A New Look, Empirically Documented, at Émile Durkheim's Theory of Collective Assemblies and Collective Effervescence

For Durkheim, individuals' survival and well-being rest on cultural resources and social belonging that must be revived periodically in collective assemblies. Durkheim's concern was to clarify how these assemblies achieve this revitalization. An intensive examination of primitive religions led him to identify successive levels of engagement experienced by participants and to develop explanatory principles relevant to all types of collective gatherings. Durkheim's conception is widely referred to nowadays. However, the question of its empirical status remains open. We extracted from his text his main statements and translated them into research questions. We then examined each question in relation to current theories and findings. In particular, we relied on the plethora of recent cognitive and social-psychology studies that document conditions of reduced self-other differentiation. Abundant data support that each successive moment of collective assemblies contributes to blurring this differentiation. Ample support also exists that because shared emotions are increasingly amplified in collective context, they can fuel high-intensity experiences. Moreover, recent studies of self-transcendent emotions can account for the self-transformative effects described by Durkheim at the climax of collective assemblies. In conclusion, this century-old model is remarkably supported by recent results, mostly collected in experimental settings.

Is two cuter than one? number and relationship effects on the feeling of kawaii toward social robots

Kawaii, which is a Japanese word that means cute, lovely, and adorable, is an essential factor in promoting positive emotions in people. The characteristics of a target's appearance that induce such feelings of kawaii have been thoroughly investigated around the notion of Konrad Lorenz's famous baby schema. Such knowledge has been exploited to design the appearance of commercial products to increase their social acceptance and commercial appeal. However, the effects of the number of targets and showing their mutual relationships (like friendship) have not been investigated in the context of kawaii. Therefore, in this study, we conducted three web-based experiments and focused on how such factors contribute to feelings of kawaii toward social robots. In Experiment 1, the feelings of kawaii toward static images of targets were compared when they appeared alone or with another target: persons (twin boys/girls), non-human objects (cherries), and social robots. The results showed that the feeling of kawaii was stronger for two targets that displayed a mutual relationship (e.g., looking at each other and/or making physical contact) than for one target alone and for two-independent targets. In Experiment 2, these findings were replicated using video clips of robots. Two-related targets were rated as more kawaii than two-independent targets or a single target. These two experiments consistently show the advantage of multiple robots that display their mutual relationship for enhancing the viewer's feeling of kawaii. Experiment 3 examined the effect of the number of robots (from one to ten) and found that two robots induced the strongest feeling of kawaii. These results indicate that not only the physical characteristics of a target itself but also the number of targets and their perceived relationships affect feelings of kawaii.

Dominance-submissiveness cues modulate pain threshold for mechanical pressure

Acute pain sensation is an inherently negative but adaptive experience; however, research on pain sensitivity shows that simple contextual cues can effectively attenuate the pain. In this study, we sought to investigate how dominance cues, manipulated as vertical spatial (i.e., height) distance between participants and experimenter, affect participants' pain sensitivity. Positioning participants in a spatially higher position relative to the experimenter was aimed to induce a feeling of dominance in participants. Conversely, a feeling of submissiveness was induced by placing the experimenter in a spatially higher position. In addition, we examined the role of dominance cues with respect to participants' and experimenters' gender. Two separate studies were conducted-Study 1 with a male experimenter measuring pain threshold in female and male participants (N = 137), and Study 2 with a female experimenter conducting pain measurement in a new sample of female and male participants (N = 122). The results of both studies demonstrated that participants in a dominant position reported a higher pain threshold relative to participants in a submissive position. Male participants had a higher pain threshold in both studies; however, Study 1 revealed a significant interaction of dominance manipulation and participant's gender, with the effect of dominance cues being larger in men.

What does it mean to follow? A critique of the followership literature and a conceptual model of the emergence of downward following

What does it mean to follow? In this paper, we systematically review the followership literature for the period 2017-2021. Our review shows that the followership literature suffers from three major issues that limit its validity. The followership field is dominated by a role-based approach equating direct reports with followers; empirical studies fail to study actual following behaviors, and there are no studies of downward following, which we define as any behavior or effort aimed at achieving a shared goal, carried out by an individual in a position of formal power who is influenced by one or more individuals in a position of inferior authority. Our manuscript builds on the process approach to study what it means to follow. We argue that the followership field needs to study actual followership behaviors at the micro "interaction episodes" and rely on quantitative behavioral coding. We then propose a conceptual, multi-level model that details antecedents and boundary conditions of the emergence of downward following. We conclude by discussing the organizational implications of our approach and model.

Human and animal dominance hierarchies show a pyramidal structure guiding adult and infant social inferences

This study investigates the structure of social hierarchies. We hypothesized that if social dominance relations serve to regulate conflicts over resources, then hierarchies should converge towards pyramidal shapes. Structural analyses and simulations confirmed this hypothesis, revealing a triadic-pyramidal motif across human and non-human hierarchies (114 species). Phylogenetic analyses showed that this pyramidal motif is widespread, with little influence of group size or phylogeny. Furthermore, nine experiments conducted in France found that human adults (N = 120) and infants (N = 120) draw inferences about dominance relations that are consistent with hierarchies' pyramidal motif. By contrast, human participants do not draw equivalent inferences based on a tree-shaped pattern with a similar complexity to pyramids. In short, social hierarchies exhibit a pyramidal motif across a wide range of species and environments. From infancy, humans exploit this regularity to draw systematic inferences about unobserved dominance relations, using processes akin to formal reasoning.

Relational models theory: Validation and replication for four fundamental relationships

Relational models theory predicts that social relationships are formed from four underlying psychological models: communal sharing, authority ranking, equality matching, and market pricing. Here, in four studies, we test this four-factor model using the 33-item Modes of Relationships Questionnaire (MORQ). In Study 1, we administered the MORQ to N = 347 subjects. A parallel analysis supported the four-factor structure, but several items failed to load on their predicted target factors. In Study 2 (N = 617), we developed a well-fitting four-factor model of the MORQ with a total of 20 items (five items retained for each factor). This model replicated across multiple relationships reported by each subject. In Study 3, we replicated the model in an independent dataset (N = 615). A general factor associated with relationship type was required in both Study 2 and Study 3. In Study 4, we tested the nature of this general factor, finding that it was associated with the closeness of the relationship. The results support the Relational Models four-factor structure of social relationships. Given the mature theory and applications in a wide range of disciplines, from social to organisational psychology, we hope that this compact, valid, and interpretable instrument leads to increased usage of the scale.

College student gratitude: A silver lining while evaluating a yearlong bathroom stall messaging campaign

OBJECTIVE

Mental health concerns of college students are on the rise, prompting a need for communication campaigns to address ways to assist students. The current campaign utilized weekly bathroom stall messaging to address five key themes developed by a university's mental wellness task force.

Participants: Undergraduate students at a large Midwestern university.

Methods: A survey at pre and post-campaign implementation.

Results: No significant shifts in attitudes, and only one significant behavioral increase (i.e., reaching out to academic advisers), were revealed. One silver lining was that college students were found to express gratitude to someone new a median of 5 times per month. Gratitude tended to be displayed most recently to those in their social circles, and primarily for receiving instrumental support.

Conclusions: Narrowing the focus of future mental wellness campaigns is recommended. Additional recommendations for developing future mental wellness campaigns are also addressed.

Shared cross-cultural principles underlie human prosocial behavior at the smallest scale

Prosociality and cooperation are key to what makes us human. But different cultural norms can shape our evolved capacities for interaction, leading to differences in social relations. How people share resources has been found to vary across cultures, particularly when stakes are high and when interactions are anonymous. Here we examine prosocial behavior among familiars (both kin and non-kin) in eight cultures on five continents, using video recordings of spontaneous requests for immediate, low-cost assistance (e.g., to pass a utensil). We find that, at the smallest scale of human interaction, prosocial behavior follows cross-culturally shared principles: requests for assistance are very frequent and mostly successful; and when people decline to give help, they normally give a reason. Although there are differences in the rates at which such requests are ignored, or require verbal acceptance, cultural variation is limited, pointing to a common foundation for everyday cooperation around the world.

Linking Judging Moral to Acting Moral: A Relational Motivations Approach to Judging and Practicing Covid-19 Behaviors

Building on the Relational Motivation Theory, the present research argues that relational motivations (RM) underlie both the regulation and the moral judgment of socially (un)responsive Covid-19 behaviors (e.g., physical distancing) and links these two via moral identity. We hypothesize that different types of socially unresponsive behaviors are judged morally wrong through perceptions of RM violations and that a stronger concern for unity predicts the extent to which individuals self-report to perform socially responsive Covid-19 behaviors. Additionally, the role of moral identity as an individual-level moderator variable linking perceptions about RM violation to the practice of Covid-19 responsible behaviors is explored. The results support the predictions with data collected from participants living in Turkey and the USA. In both cultures, socially unresponsive Covid-19 behaviors of others were judged morally wrong through RMs, plus individuals' general concern for unity predicted their self-reported socially responsive Covid-19 behaviors. Additionally, for the sample from Turkey, results revealed that the general concern for unity was positively associated with self-reported tendencies to perform Covid-19 socially responsive behaviors only among individuals with a low or moderate moral identity, but not when moral identity was high.

The dynamics of intergenerational closure and family networks of social cohesion

We investigate the correlation of ties among school-children's parents with violence in schools, and two mechanisms of intergenerational closure (IC). Coleman described ties among parents of befriended children as IC. Until now, IC indicated social capital in schools and neighborhoods, but existing evidence is rather ambiguous and does not utilize network data. According to "top-down." IC, children establish network ties because of the acquaintance among their parents. "Bottom-up" IC implies that children make friends first and then their parents get involved. We use longitudinal social network data from k = 10 school classes and N = 238 adolescents and disentangle the two different dynamics of IC by applying Bayesian stochastic actor-oriented models (SAOMs) for network evolution. SAOMs show positive "top-down" and "bottom-up" effects on IC, with the latter being considerably stronger.

Be Our Guest: The Development of the Interpersonal Hospitality Scale

Despite the ubiquity of hosting others in one's home, no validated measure of domestic hospitality currently exists. To address this gap, the current paper presents a set of four studies that develop and validate the Interpersonal Hospitality Scale, which seeks to capture the affective, motivational, and behavioral components of this person-place construct. The 12-item scale assesses three core dimensions: responsibility for guests, welcomingness, and a lack of perceived imposition. The analyses reported here provide support for the psychometric adequacy of this new scale, demonstrating strong internal reliability and a consistent factor structure. Moreover, this trait was found to be a unique predictor of several theoretically related constructs, including one's desired home ambiance, attitudes toward immigration, and willingness/likelihood of hosting others in need. This scale offers a much-needed means of measuring one important aspect of how people conceptualize their home environment relative to others.

Korrika, running in collective effervescence through the Basque Country: A model of collective processes and their positive psychological effects

The neo-Durkheimnian model suggests that feedback and emotional communion between participants during a collective gathering (i.e., perceived emotional synchrony: PES) is one of the key mechanisms of collective processes. This shared emotional experience gives rise, in turn, to more intense emotions, this being one of the explanatory models of the positive psychological effects of collective participation. Through a quasi-longitudinal design of three measurement-times (N = 273, 65.9% women; age: 18-70, M = 39.43, SD = 11.64), the most massive social mobilization that is celebrated in favor of the Basque language in the Basque Country (Korrika) was analyzed. Repeated measures and sequential mediation analyzes supported the model. The effect of participation on social integration was mediated by the increase in emotions of enjoyment through PES; the effect on social acceptance, social contribution, and social actualization was mediated by increased kama muta through PES; the effect on collective empowerment was mediated by the increase in self-transcendent emotions through PES; and the effect on remembered well-being was partially mediated by PES. Finally, it was also verified for the first time that the effect of participation on social integration, social acceptance and social actualization was maintained through PES (but not through emotions) for at least 6-7 weeks after the event ended. Also, it is concluded that Kama muta is a relevant emotion during collective gatherings.

Enculturating the Science of International Development: Beyond the WEIRD Independent Paradigm

Initiatives in international development and behavioral science rely predominantly on the independent models of the self and agency that are prevalent in individualist Western, Educated, Industrialized, Rich, and Democratic (WEIRD) cultural contexts. Programs that are guided by these independent models, explicitly or implicitly, as the default way of being and that neglect interdependent models can reduce the potential of development initiatives to advance poverty reduction and well-being in two ways. First, programs based solely on independent models of agency—centered on personal goals and values; self-advancement and self-expression; and autonomy—can limit the scope and effectiveness of the development science toolkit. Second, programs that are not responsive to interdependent ways of being—centered on relational goals and values; responsiveness to social norms, roles, and obligations; and social coordination—that are common in many Global South sociocultural contexts can be met with resistance or backlash. We propose that taking account of interdependent psychosocial tendencies is a promising way to diversify the behavioral science toolkit and to build a more comprehensive science of human behavior. Furthermore, culturally responsive program designs have the potential both to promote decolonized, inclusive approaches that preserve rather than override local ways of being and to enable diverse trajectories of societal development to flourish. We integrate experimental and descriptive research from psychology, economics, education, and global health to suggest how models of interdependent agency can be productively integrated into development program designs to advance quality of life in locally resonant ways.

To kill or not to kill: A systematic literature review of high-stakes moral decision-making measures and their psychometric properties

Introduction

The present systematic review investigates the psychological tools available for capturing high-stakes decisions involving life-death content and their psychometric properties. Valid measurement of these individual differences will provide crucial information in the personnel selection and training in fields where high-stakes moral issues exist (e.g., military, medicine). To our knowledge, this is the first systematic examination of such instruments.

Methods

Systematic searches of 6 electronic databases were conducted according to the PRISMA guidelines. An appraisal tool evaluated the quality of identified measures. Twenty studies met pre-determined inclusion criteria. Moral decision-making was assessed with either a self-report scale (n = 3) or moral dilemmas (n = 17).

Results

The findings identified two measures, the Defining Issues Test and the Oxford Utilitarianism Scale as psychometrically sound measures of moral decision-making. However, they are unlikely to be considered "gold standard" measures due to their theoretically specific, but limited, scope. Overall, the findings suggest that research in the area has been scattered. There is a lack of consensus on the definition of moral decision-making, and a lack of cross-validation on how different measures of moral decision-making relate to each other. This presents a gap between theory and empirical measurement in moral decision-making. Further work is needed for a unified conceptualization of moral decision-making to pave the way to both theory development and the development of well-validated measurement tools, and this review provides a critical foundation for both.

The construct of cuteness: A validity study for measuring content and evoked emotions on social media

Social media users are often exposed to cute content that evokes emotional reactions and influences them to feel or behave certain ways. The cuteness phenomenon in social media has been scarcely studied despite its prevalence and potential to spread quickly and affect large audiences. The main framework for understanding cuteness and emotions related to cuteness outside of social media is baby schema (having juvenile characteristics), which triggers parental instincts. We propose that baby schema is a necessary but not sufficient component of explaining what constitutes cuteness and how people react to it in the social media context. Cute social media content may also have characteristics that evoke approach motivations (a desire to interact with an entity, generally with the expectation of having a positive experience) that can manifest behaviorally in sharing and other prosocial online behaviors. We developed and performed initial validation for measures in social media contexts of: (1) cute attributes that encompass both baby schema and other proposed cuteness characteristics (the Cuteness Attributes Taxonomy, CAT) and (2) the emotional reactions they trigger (Heartwarming Social Media, HSM). We used the Kama Muta Multiplex Scale (KAMMUS Two), as previously validated measure of kama muta (an emotion akin to tenderness; from Sanskrit, "moved by love") as a measure of emotional reaction to cute stimuli and the dimension Cute Content of the Social Media Emotions Annotation Guide (SMEmo-Cute Content) as a developed measure of gestalt cute content to help validate our newly developed measures. Using 1,875 Polish tweets, our results confirmed that cute social media content predicted a kama muta response, but not all KAMMUS Two subscales were sensitive to cute content, and that the HSM measure was a better indicator of the presence of cute content. Further, the CAT measure is an effective means of categorizing cute attributes of social media content. These results suggest potential differences between in-person, online, and social media experiences evoking cute emotional reactions, and the need for metrics that are developed and validated for use in social media contexts.

Global heart warming: kama muta evoked by climate change messages is associated with intentions to mitigate climate change

Concern about climate change is often rooted in sympathy, compassion, and care for nature, living beings, and future generations. Feeling sympathy for others temporarily forms a bond between them and us: we focus on what we have in common and feel a sense of common destiny. Thus, we temporarily experience communal sharing relationships. A sudden intensification in communal sharing evokes an emotion termed kama muta, which may be felt through tearing up, a warm feeling in the chest, or goosebumps. We conducted four pre-registered studies (n = 1,049) to test the relationship between kama muta and pro-environmental attitudes, intentions, and behavior. In each study, participants first reported their attitudes about climate change. Then, they received climate change-related messages. In Study 1, they saw one of the two moving video clips about environmental concerns. In Study 2, participants listened to a more or less moving version of a story about a typhoon in the Philippines. In Study 3, they listened to a different, also moving version of this story or an unrelated talk. In Study 4, they watched either a factual or a moving video about climate change. Participants then indicated their emotional responses. Finally, they indicated their intentions for climate mitigation actions. In addition, we measured time spent reading about climate-related information (Studies 1, 2, and 4) and donating money (Study 4). Across all studies, we found that feelings of kama muta correlated positively with pro-environmental intentions (r = 0.48 [0.34, 0.62]) and behavior (r = 0.10 [0.0004, 0.20]). However, we did not obtain evidence for an experimental effect of the type of message (moving or neutral) on pro-environmental intentions (d = 0.04 [-0.09, 0.18]), though this relationship was significantly mediated by felt kama muta across Studies 2-4. The relationship was not moderated by prior climate attitudes, which had a main effect on intentions. We also found an indirect effect of condition through kama muta on donation behavior. In sum, our results contribute to the question of whether kama muta evoked by climate-change messages can be a motivating force in efforts at climate-change mitigation.

Market exposure and human morality

According to evolutionary theories, markets may foster an internalized and universalist prosociality because it supports market-based cooperation. This paper uses the cultural folklore of 943 pre-industrial ethnolinguistic groups to show that a society's degree of market interactions, proxied by the presence of intercommunity trade and money, is associated with the cultural salience of (1) prosocial behaviour, (2) interpersonal trust, (3) universalist moral values and (4) moral emotions of guilt, shame and anger. To provide tentative evidence that a part of this correlation reflects a causal effect of market interactions, the analysis leverages both fine-grained geographic variation across neighbouring historical societies and plausibly exogenous variation in the presence of markets that arises through proximity to historical trade routes or the local degree of ecological diversity. The results suggest that the coevolutionary process involving markets and morality partly consists of economic markets shaping a moral system of a universalist and internalized prosociality.

Justice Evaluation of the Income Distribution (JEID): Development and validation of a short scale for the subjective assessment of objective differences in earnings

Justice evaluations are proposed to provide a link between the objective level of inequality and the consequences at the individual and societal level. Available instruments, however, focus on the subjective perception of inequality and income distributions. In light of findings that subjective perceptions of inequality and income levels can be biased and subject to method effects, we present the newly developed Justice Evaluation of the Income Distribution (JEID) Scale, which captures justice evaluations of the actual earnings distribution. JEID comprises five items that provide respondents with earnings information for five groups at different segments along the distribution of earnings in a given country. We provide a German-language and an English-language version of the scale. The German-language version was developed and validated based on three comprehensive heterogeneous quota samples from Germany; the translated English-language version was validated in one comprehensive heterogeneous quota sample from the UK. Using latent profile analysis and k-means clustering, we identified three typical response patterns, which we labeled "inequality averse," "bottom-inequality averse," and "status quo justification." JEID was found to be related to normative orientations in the sense that egalitarian views were associated with stronger injustice evaluations at the bottom and top ends of the earnings distribution. With a completion time of between 1.50 and 2.75 min, the JEID scale can be applied in any self-report survey in the social sciences to investigate the distribution, precursors, and consequences of individuals' subjective evaluations of objective differences in earnings.

Development and initial validation of the Partnership Scale-DanceSport Couples

Introduction

DanceSport is described as a dance involving a male-female partner. It is important to comprehend the partnership between dance couples so that their competitive performance can be effectively supported. However, only a few studies have verified the influence of partnership between DanceSport couples on competitive performance and explored its psychological mechanism to provide means to deal with the partnership. The reason was that there was a lack of appropriate assessment tools.

Aims

This multi-study outlines the development, content, and construct validity of a novel, mixed-method tool to assess DanceSport partnership.

Methods

The development of the Partnership Scale-DanceSport Couples (PS-DSC) included four studies and data from four samples of Chinese elite dancers (N = 914 total). In stage 1, outlined in study 1, PS-DSC items were generated and then refined using the feedback provided by academics, sports coaches, and elite dancers. In stage 2, outlined in studies 2 and 3, exploratory factor analysis and confirmatory factor analysis were used to examine the structure of the PS-DSC items. In stage 3, outlined in study 4, composite reliability, discriminant validity, and convergent validity were assessed. The result of this process was a 13-item three-factor instrument. Based on these initial findings, the PS-DSC provided the first valid and reliable way of measuring partnerships between DanceSport couples.

Conclusion

This study has taken the promising first step in developing a tool to comprehensively measure partnerships between DanceSport couples.

A long-term negative effect of monetary incentives on the participatory surveillance of animal disease: a pilot study in Chiang Mai, Thailand

BACKGROUND

In general, animal diseases have a significant impact on public health; accordingly, an effective animal disease surveillance system is an important control system that requires efficient and engaging participants in the long run. The purpose of this study is to assess the impact of monetary and social motivation on animal disease surveillance. We hypothesized that there are two sorts of motivation based on Fiske's relational theory (1992): monetary incentives (monetary markets) and nonmonetary incentives (social markets).

METHODS

In Chiang Mai Province, Northern Thailand, we analyzed data from a pilot project that began in 2014 and used a mobile application to report on signs that identify animal health problems. A total of 67 participants from 17 different areas in the central part of the province participated in this study. Participants in this study were divided into two groups: those who received monetary incentives and those who received social incentives.

RESULTS

According to the findings, the monetary market group's effort was significantly higher than that of the social market group during the time when the volunteers in the monetary market group were paid. However, in the long run, the monetary market group reported significantly less than the social market group. Social incentive, on the other hand, was more efficient once the payment period ended.

CONCLUSIONS

Social incentive outperformed monetary motivation in terms of efficiency and sustainability in the long run. Not only did the volunteers who were offered monetary incentive put in less effort than those who were offered the social incentive, but they were also not remotivated by the social incentive after the payment period had ended.

Sosyal Biliş Becerilerinin Sosyal Kaygı Üzerindeki Yordayıcı Etkisi

Bu çalışmanın temel amacı sosyal kaygı ile sosyal biliş becerileri (duygu tanıma/ayırt etme, zihin kuramı, atıf yanlılığı, sosyal işlevsellik) arasındaki ilişkiyi incelemek ve sosyal biliş becerilerinin sosyal kaygıyı yordama gücünü araştırmaktır. Çalışmada ayrıca sosyal kaygı, sosyal biliş becerileri ve depresyon puanlarının cinsiyet, yaş, bildirilen tanı durumu ve sosyal kaygı düzeyine göre farklılaşıp farklılaşmadığı araştırılmıştır. Çalışmanın örneklemini, 18-60 yaşları arasında bulunan toplam 385 kişi oluşturmuştur. Araştırma verileri çevrimiçi olarak Liebowitz Sosyal Anksiyete Ölçeği, Yüzde Dışavuran Duyguların Tanınması ve Ayırt Edilmesi Testi, Gözlerden Zihin Okuma Testi, İçsel, Kişisel ve Durumsal Atıflar Ölçeği, Sosyal İşlevsellik Ölçeği, Beck Depresyon Envanteri ve Sosyodemografik Bilgi Formu kullanılarak katılımcılardan toplanmıştır. Sosyal kaygı ile duygu tanıma, duygu ayırt etme ve gözlerden zihin okuma arasında negatif, dışsallaştırma yanlılığı ve depresyon ile ise pozitif yönde anlamlı ilişki olduğu belirlenmiştir. Depresyon, duygu tanıma ve ayırt etme, gözlerden zihin okuma ve öncül sosyal etkinlikler ölçek puanlarının sosyal kaygıyı anlamlı düzeyde yordadığı bulunmuştur. Bu değişkenler sosyal kaygıya ilişkin toplam varyansın %52’sini açıklamaktadır. Ayrıca, depresyon etkisi kontrol edildiğinde sosyal biliş becerilerinin sosyal kaygıya ilişkin varyansın %32’sini açıkladığı görülmüştür. Sosyal biliş becerilerindeki bozulmanın ve depresyon puanlarının sosyal kaygının artışıyla ilişkili olduğu belirlenmiştir. Araştırmadan elde edilen sonuçlara göre, sosyal kaygıyı önlemeye yönelik önerilerde bulunulmuştur. Müdahale programları içerisinde bireylerin kişilerarası iletişimi için önemli olan sosyal biliş becerilerini geliştirmeye yönelik etkinliklere yer verilmesinin yararlı olacağı önerilmektedir.

Multidimensional tie strength and economic development

The strength of social relations has been shown to affect an individual's access to opportunities. To date, however, the correspondence between tie strength and population's economic prospects has not been quantified, largely because of the inability to operationalise strength based on Granovetter's classic theory. Our work departed from the premise that tie strength is a unidimensional construct (typically operationalized with frequency or volume of contact), and used instead a validated model of ten fundamental dimensions of social relationships grounded in the literature of social psychology. We built state-of-the-art NLP tools to infer the presence of these dimensions from textual communication, and analyzed a large conversation network of 630K geo-referenced Reddit users across the entire US connected by 12.8M social ties created over the span of 7 years. We found that unidimensional tie strength is only weakly correlated with economic opportunities ([Formula: see text]), while multidimensional constructs are highly correlated ([Formula: see text]). In particular, economic opportunities are associated to the combination of: (i) knowledge ties, which bridge geographically distant groups, facilitating the knowledge dissemination across communities; and (ii) social support ties, which knit geographically close communities together, and represent dependable sources of social and emotional support. These results point to the importance of developing high-quality measures of tie strength in network theory.

Market mindset reduces endorsement of individualizing moral foundations, but not in liberals

People with a market mindset attend to ratios and rates, and allocate rewards adequately to costs but are less sensitive to feelings. In this project, we demonstrate that activating a market mindset also affects people’s acceptance of free-market principles and their endorsement of individualizing moral dimensions—care/harm and fairness/cheating. Experiment 1 documented that a market mindset positively impacted people’s endorsement of fair market ideology. Experiments 2 and 3 showed that the salience of such a market mindset hampered the importance of individualizing moral dimensions. Importantly, we found that political orientation moderated the negative effect of a market mindset on the endorsement of individualizing moral foundations—this effect held for participants who declared moderate and conservative political orientations, but not for liberals.

Go for zero tolerance: Cultural values, trust, and acceptance of zero-COVID policy in two Chinese societies

This study seeks to explain the wide acceptance of the stringent zero-COVID policy in two Chinese societies-Mainland China (n = 2,184) and Taiwan (n = 1,128)-from perspectives of cultural values and trust. By employing the efficacy mechanism, this study identifies significant indirect effects of trust in government and key opinion leaders (KOL) on people's policy acceptance in both societies. Namely, people who interpret the pandemic as a collectivist issue and who trust in government will be more accepting of the zero-COVID policy, whereas those who framed the pandemic as an individual issue tend to refuse the policy. Trust in government and KOLs foster these direct relationships, but trust in government functions as a more important mediator in both societies. The different contexts of the two Chinese societies make the difference when shaping these relationships. These findings provide practical considerations for governmental agencies and public institutions that promote the acceptance of the zero-COVID policy during the pandemic.
