Economic dishonesty is a widespread behavior that has substantial implications on organizations and societies. Recent studies suggest that decision making in groups or commitment to other individuals can further increase such dishonesty in contrast to individual decision making.

Emotional crying is a complex and multifaceted expression that is frequently observed in humans. Its communicative effects have been recently studied in more detail. However, many studies focus on just one specific feature of emotional crying, most often emotional tears, neglecting the complex nature of the expression. Reports about crying episodes...

Though people usually imagine the typical person as a man rather than a woman, the effect is mixed for racial groups and understudied among traditionally male social groups (e.g., police and criminals) and non-U.S. populations. Results from a survey (N > 5000) collected via a globally distributed laboratory network in over 40 regions demonstrated t...

Dishonest behaviours such as tax evasion impose significant societal costs. Ex ante honesty oaths—commitments to honesty before action—have been proposed as interventions to counteract dishonest behaviour, but the heterogeneity in findings across operationalizations calls their effectiveness into question. We tested 21 honesty oaths (including a ba...

Positive emotions have important functions related to intra- and interindividual flourishing and well-being. At the turn of the century the interest in distinct positive emotions and their importance has skyrocketed due to the positive psychology movement. Since then, researchers have explored positive emotions beyond the category of happiness and...

Dishonest behavior is a prevalent phenomenon, and recent studies have suggested that seemingly trivial factors, such as the time of the day, can influence individuals’ propensity to act dishonestly. Specifically, research has identified a phenomenon known as the Morning Morality Effect, where participants exhibit greater dishonesty during the after...

People feel committed to other individuals, groups, organizations, or moral norms in many contexts of everyday life. Such social commitment can lead to positive outcomes, such as increased job satisfaction or relationship longevity; yet, there can also be detrimental effects to feeling committed. Recent high-profile cases of fraud or corruption in...

Emotional tears represent a basic expressive response that is most likely unique to humans. Researchers have debated the specific function of this phenomenon, with recent propositions suggesting that it mainly works as an interpersonal communicative signal motivating observers to provide help and social support to the tearful person. Here, we revie...

Tearful faces are frequent in mass media portraits of refugees, but the consequences of such depictions for different kinds of intergroup helping remain poorly understood. Moreover, existing research suggests that individuals tend to be more willing to support those who display tears, yet the impact of emotional tears on actual helping behavior has...

Social commitment influences our behavior in various ways. Recent studies suggest that social commitment to other individuals or groups can increase dishonest behavior while feeling commitment to moral norms might decrease it. Here we show in a pre-registered series of 7 studies investigating the influence of social commitment on dishonest behavior...

Mental simulation theories of language comprehension propose that people automatically create mental representations of objects mentioned in sentences. Mental representation is often measured with the sentence-picture verification task, wherein participants first read a sentence that implies the object property (i.e., shape and orientation). Partic...

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 in...

Many situations elicit multiple emotions at the same time. Therefore, emotion theories should explain when and how emotions co-occur. We compared four parsimonious, formal theories that could explain emotion co-occurrence inspired by distinct emotion, network, and dimensional approaches to emotions. In three studies (N = 1,038), diverse participant...

In response to the COVID-19 pandemic, the Psychological Science Accelerator coordinated three large-scale psychological studies to examine the effects of loss-gain framing, cognitive reappraisals, and autonomy framing manipulations on behavioral intentions and affective measures. The data collected (April to October 2020) included specific measures...

Most consumers say they are willing to consume more sustainably, but this does not often translate into commensurate behavior. To investigate this discrepancy in the context of smartphone purchase, a pre-registered online study (total N = 2,202) was conducted in four countries: the Netherlands, Germany, France, and the United Kingdom. We used an at...

Classic findings from psychology and the behavioural sciences are increasingly being revisited. Methodological and technological advances provide opportunities to replicate studies across a wide range of countries and settings to investigate whether these findings are universally applicable, limited to specific countries, or vary in magnitude depen...

People cry for various reasons and in numerous situations, some involving highly moral aspects such as altruism or moral beauty. At the same time, criers have been found to be evaluated as more morally upright—they are perceived as more honest, reliable, and sincere than non-criers. The current project provides a first comprehensive investigation t...

Social commitment (i.e., feeling committed to other individuals or groups) influences our behavior in various ways. Recent studies suggest that social commitment can increase dishonest behavior, while feeling commitment to social norms might decrease it. However, recent meta-investigations highlight severe heterogeneity of these effects. Additional...

Computational views of perception do not consider affect to be required to solve a perceptual task. Previous research provided evidence for an affective component in early perceptual processes, but it is unclear whether late perceptual processes yield concomitant affect. Three studies using three different tasks explored changes in affect related t...

The COVID-19 pandemic (and its aftermath) highlights a critical need to communicate health information effectively to the global public. Given that subtle differences in information framing can have meaningful effects on behavior, behavioral science research highlights a pressing question: Is it more effective to frame COVID-19 health messages in t...

The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about...

This paper provides an accessible review of the biological and psychological evidence to guide new and experienced researchers in the study of emotional piloerection in humans. A limited number of studies have attempted to examine the physiological and emotional correlates of piloerection in humans. However, no review has attempted to collate this...

Significance Communicating in ways that motivate engagement in social distancing remains a critical global public health priority during the COVID-19 pandemic. This study tested motivational qualities of messages about social distancing (those that promoted choice and agency vs. those that were forceful and shaming) in 25,718 people in 89 countries...

People feel committed to other individuals, groups, or organizations in many contexts in everyday life. Such social commitment can have many positive outcomes, related to job satisfaction or relationship longevity, but there might also be detrimental effects when feeling overly committed. Recent high-profile cases of fraud or corruption in companie...

Research on the effect of emotional tears on perceived competence has yielded an inconsistent pattern of findings, with some studies showing that tearful individuals may be perceived as less competent, while others report no such effect. These mixed results point to the likely existence of third variables influencing the link between tears and perc...

The experience often described as feeling moved, understood chiefly as a social-relational emotion with social bonding functions, has gained significant research interest in recent years. Although listening to music often evokes what people describe as feeling moved, very little is known about the appraisals or musical features contributing to the...

Various theories have tried to make sense of human emotional crying, predicting different psychophysiological correlates. In the present paper, we systematically review empirical studies on this relationship. Our preregistered meta-analysis identified 230 effect sizes across 12 articles (N=1,017), focusing on 18 measures reflecting cardiovascular,...

Tearful crying is a ubiquitous and likely uniquely human phenomenon. Scholars have argued that emotional tears serve an attachment function: Tears are thought to act as a social glue by evoking social support intentions. Initial experimental studies supported this proposition across several methodologies, but these were conducted almost exclusively...

Effectively motivating social distancing—keeping a physical distance from others —has become a global public health priority during the COVID-19 pandemic. This cross-country preregistered experiment (n=25,718 in 89 countries) tested hypotheses derived from self-determination theory concerning generalizable positive and negative outcomes of differen...

Finding communication strategies that effectively motivate social distancing continues to be a global public health priority during the COVID-19 pandemic. This cross-country, preregistered experiment (n = 25,718 from 89 countries) tested hypotheses concerning generalizable positive and negative outcomes of social distancing messages that promoted p...

A widespread perspective describes emotions as distinct categories bridged by fuzzy boundaries, indicating that emotions are distinct and dimensional at the same time. Theoretical and methodological approaches to this perspective still need further development. We conceptualize emotions as overlapping networks of causal relationships between emotio...

Over the past 10 years, Oosterhof and Todorov’s valence–dominance model has emerged as the most prominent account of how people evaluate faces on social dimensions. In this model, two dimensions (valence and dominance) underpin social judgements of faces. Because this model has primarily been developed and tested in Western regions, it is unclear w...

Although several scholars acknowledge the existence of tears of joy, there is little systematic theoretical or empirical evidence on how positive tears are experienced, what elicits them, what actions or impulses they motivate in the crier, how they differ from tears of sadness or distress and whether there are different types. We systematically in...

Tearful crying is a ubiquitous and likely uniquely human phenomenon. The persistence of this behavior throughout adulthood has fascinated and puzzled many researchers. Scholars have argued that emotional tears serve an attachment function: Tears are thought to act as a social glue by triggering social support intentions. Initial experimental studie...

The coronavirus outbreak manifested in Norway in March 2020. It was met with a combination of mandatory changes (closing of public institutions) and recommended changes (hygiene behavior, physical distancing). It has been emphasized that health-protective behavior such as increased hygiene or physical distancing are able to slow the spread of infec...

Situations involving increased closeness or exceptional kindness are often labeled as moving or touching and individuals often report bodily symptoms, including tears, goosebumps, and warmth in the body. Recently, the kama muta framework has been proposed as a cross‐cultural conceptualization of these experiences. Prior research on kama muta has mo...

The expectations that PhD students face in the social sciences have been increasing steadily. At the same time, the behavioral and social sciences have faced a substantial turmoil questioning the reproducibility of research findings and the way how researchers should perform research. In the present chapter, we provide guidance on possible ways how...

Over the last ten years, Oosterhof and Todorov’s valence-dominance model has emerged as the most prominent account of how people evaluate faces on social dimensions. In this model, two dimensions (valence and dominance) underpin social judgments of faces. Because this model has primarily been developed and tested in Western regions, it is unclear w...

In the Human Penguin Project (N = 1755), 15 research groups from 12 countries collected body temperature, demographic variables, social network indices, seven widely-used psychological scales and two newly developed questionnaires (the Social Thermoregulation and Risk Avoidance Questionnaire (STRAQ-1) and the Kama Muta Frequency Scale (KAMF)). They...

A configuration of infantile attributes including a large head, large eyes, with a small nose and mouth low on the head comprise the visual baby schema or Kindchenschema that English speakers call “cute.” In contrast to the stimulus gestalt that evokes it, the evoked emotional response to cuteness has been little studied, perhaps because the emotio...

When do people say that they are moved, and does this experience constitute a unique emotion? We review theory and empirical research on being moved across psychology and philosophy. We examine feeling labels, elicitors, valence, bodily sensations, and motivations. We find that the English lexeme being moved typically (but not always) refers to a d...

Social thermoregulation theory posits that modern human relationships are pleisiomorphically organized around body temperature regulation. In two studies (N = 1755) designed to test the principles from this theory, we used supervised machine learning to identify social and non-social factors that relate to core body temperature. This data-driven an...

Concerns about the veracity of psychological research have been growing. Many findings in psychological science are based on studies with insufficient statistical power and nonrepresentative samples, or may otherwise be limited to specific, ungeneralizable settings or populations. Crowdsourced research, a type of large-scale collaboration in which...

English-speakers sometimes say that they feel moved to tears, emotionally touched, stirred, or that something warmed their heart; other languages use similar passive contact metaphors to refer to an affective state. We propose and measure the concept of kama muta to understand experiences often given these and other labels. Do the same experiences...

Some political ads used in the 2016 U.S. election evoked feelings colloquially known as being moved to tears. We conceptualise this phenomenon as a positive social emotion that appraises and motivates communal relations, is accompanied by physical sensations (including lachrymation, piloerection, chest warmth), and often labelled metaphorically. We...

Recent work investigated the inter-individual functions of emotional tears in depth. In one study (Van de Ven, N., Meijs, M. H. J., & Vingerhoets, A. (2017). What emotional tears convey: Tearful individuals are seen as warmer, but also as less competent. British Journal of Social Psychology, 56(1), 146–160. Https://doi.org/10.1111/bjso.12162) tearf...

Ethnographies, histories, and popular culture from many regions around the world suggest that marked moments of love, affection, solidarity, or identification everywhere evoke the same emotion. Based on these observations, we developed the kama muta model, in which we conceptualize what people in English often label being moved as a culturally impl...

As evidence for the second process of the Embracing factor, the target article characterizes being moved as a mixed emotion linked to sadness through metonymy. We question these characterizations and argue that emotions should not be equated with their vernacular labels.

Although daily meat consumption is a widespread habit, many individuals at the same time put a high value on the welfare of animals. While different psychological mechanisms have been identified to resolve this cognitive tension, such as dissociating the animal from the consumed meat or denying the animal's moral status, few studies have investigat...

Seeing someone in need may evoke a particular kind of closeness that has been conceptualized as sympathy or empathic concern (which is distinct from other empathy constructs). In other contexts, when people suddenly feel close to others, or observe others suddenly feeling closer to each other, this sudden closeness tends to evoke an emotion often l...

Although the concept of inclusion of the other in the self (IOS) has been successfully assessed with explicit self-report measures, implicit procedures have been neglected in past literature. The present article explores the validity of such an implicit measure by proposing several extensions and adaptions. We addressed methodological problems of a...

Sample: We discovered that events of positive tears, rather than negative tears, were associated with self-reported being moved or touched, with goosebumps, with feelings of chest warmth, and with the appraisals of increased closeness and moral acts. These appraisals mediated the difference in being moved between positive and negative events. We f...

Feeling moved or touched can be accompanied by tears, goosebumps, and sensations of warmth in the centre of the chest. The experience has been described frequently, but psychological science knows little about it. We propose that labelling one’s feeling as being moved or touched is a component of a social-relational emotion that we term kama muta (...
