Adaptive responses to social exclusion: social rejection improves detection of real and fake smiles

Understanding the link between theory of mind and loneliness among primary school students: A cross-lagged panel model analysis

This study aimed to investigate the longitudinal association between theory of mind (ToM) and loneliness as well as the potential moderating effects of parenting style on this association. A total of 689 Chinese third-grade students (341 girls and 348 boys; Mage = 9.23 years, SD = 0.66) were recruited from eight primary schools and were followed from Grade 3 to Grade 5. These students reported their primary caregivers' parenting style in third grade and completed the same ToM task and loneliness questionnaire at each time point from Grade 3 to Grade 5. The study's results indicated a bidirectional relationship between ToM and loneliness, implying that children with less developed ToM abilities tend to feel lonelier and, conversely, that higher levels of loneliness are associated with lower ToM skills. Moreover, the study demonstrated that parenting style influenced the association between ToM and loneliness. Specifically, the impact of ToM at Grade 3 on reducing loneliness at Grade 4 was greater among children who experienced high levels of rejection from their caregivers compared with those with low levels of rejection. In addition, this study found that loneliness at Grade 3 had a greater influence on ToM at Grade 5 for children experiencing low levels of emotional warmth from their caregivers than for those who experienced high levels of emotional warmth. These findings highlight the significance of ToM as both a precursor and consequence of children's loneliness and emphasize the variation in these longitudinal relationships based on the parenting styles of primary caregivers.

Mitigating the affective and cognitive consequences of social exclusion: an integrative data analysis of seven social disconnection interventions

BACKGROUND

Being socially excluded has detrimental effects, with prolonged exclusion linked to loneliness and social isolation. Social disconnection interventions that do not require direct support actions (e.g., "how can I help?") offer promise in mitigating the affective and cognitive consequences of social exclusion. We examine how various social disconnection interventions involving friends and unknown peers might mitigate social exclusion by buffering (intervening before) and by promoting recovery (intervening after).

METHODS

We present an integrative data analysis (IDA) of five studies (N = 664) that systematically exposed participants to exclusion (vs. inclusion) social dynamics. Using a well-validated paradigm, participants had a virtual interaction with two other people. Unbeknownst to participants, the other people's behavior was programmed to either behave inclusively toward the participant or for one to behave exclusively. Critically, our social disconnection interventions experimentally manipulated whether a friend was present (vs. an unknown peer vs. being alone), the nature of interpersonal engagement (having a face-to-face conversation vs. a reminder of an upcoming interaction vs. mere presence), and the timing of the intervention in relation to the social dynamic (before vs. during vs. after). We then assessed participants' in-the-moment affective and cognitive responses, which included mood, feelings of belonging, sense of control, and social comfort.

RESULTS

Experiencing exclusion (vs. inclusion) led to negative affective and cognitive consequences. However, engaging in a face-to-face conversation with a friend before the exclusion lessened its impact (p < .001). Moreover, a face-to-face conversation with a friend after exclusion, and even a reminder of an upcoming interaction with a friend, sped-up recovery (ps < .001). There was less conclusive evidence that a face-to-face conversation with an unknown peer, or that the mere presence of a friend or unknown peer, conferred protective benefits.

CONCLUSIONS

The findings provide support for the effectiveness of social disconnection interventions that involve actual (i.e., face-to-face) or symbolic (i.e., reminders) interactions with friends. These interventions target momentary vulnerabilities that arise from social exclusion by addressing negative affect and cognitions before or after they emerge. As such, they offer a promising approach to primary prevention prior to the onset of loneliness and social isolation.

Emotional experiences of ghosting

Although ghosting (i.e., unilaterally ending a relationship by ceasing communication) has only recently entered the lexicon, it is a regularly used form of relationship dissolution. However, little research has examined the emotional experiences of ghosting, particularly the experiences of those on both sides of the ghosting process. In a multi-method study, participants who had both ghosted and been ghosted in previous romantic relationships (N = 80) provided narratives of their experiences and completed questionnaires. The narrative responses were analyzed by coders and by using LIWC. Ghosters and ghostees used similar overall levels of positively and negatively valenced words to describe their experiences, but ghosters were more likely to express guilt and relief, whereas ghostees were more likely to express sadness and hurt feelings. Ghostees also experienced more of a threat to their fundamental needs - control, self-esteem, belongingness, meaningful existence - than ghosters.

Effects of two different social exclusion paradigms on ambiguous facial emotion recognition

Social exclusion is an emotionally painful experience that leads to various alterations in socio-emotional processing. The perceptual and emotional consequences that may arise from experiencing social exclusion can vary depending on the paradigm used to manipulate it. Exclusion paradigms can vary in terms of the severity and duration of the leading exclusion experience, thereby classifying it as either a short-term or long-term experience. The present study aimed to study the impact of exclusion on socio-emotional processing using different paradigms that caused experiencing short-term and imagining long-term exclusion. Ambiguous facial emotions were used as socio-emotional cues. In study 1, the Ostracism Online paradigm was used to manipulate short-term exclusion. In study 2, a new sample of participants imagined long-term exclusion through the future life alone paradigm. Participants of both studies then completed a facial emotion recognition task consisting of morphed ambiguous facial emotions. By means of Point of Subjective Equivalence analyses, our results indicate that the experience of short-term exclusion hinders recognising happy facial expressions. In contrast, imagining long-term exclusion causes difficulties in recognising sad facial expressions. These findings extend the current literature, suggesting that not all social exclusion paradigms affect socio-emotional processing similarly.

Hippocampal volume mediates the relationship of parental rejection in childhood with social cognition in healthy adults

Childhood abuse reduces hippocampal and amygdala volumes and impairs social cognition, including the ability to recognize facial expressions. However, these associations have been studied primarily in individuals with a history of severe abuse and psychiatric symptoms; researchers have not determined whether these associations can also be observed in healthy adults. In the present study, we analyzed data from 400 healthy adults (208 men and 192 women) at Tamagawa University. Parental rejection reflecting childhood abuse was assessed using the short form of Egna Minnen Beträffande Uppfostran, while social cognition was assessed using the "Fake Smile Detection Task." Hippocampal and amygdala volumes were extracted from T1-weighted magnetic resonance imaging data using FreeSurfer. We found that greater parental rejection resulted in smaller hippocampal and amygdala volumes and poorer performance in the Fake Smile Detection Task. Structural equation modeling analysis supported the model that hippocampal volume mediates maternal rejection effect on performance on the Fake Smile Detection Task, with involvement of the amygdala. These findings are in line with the structural and functional connectivity found between the hippocampus and amygdala and their joint involvement in social cognition. Therefore, parental rejection may affect hippocampal and amygdala volumes and social cognitive function even in symptom-free adults.

Excluded and myopic: Social exclusion increases temporal discounting

Social exclusion is a painful yet ubiquitous experience that modulates affect, behavior, and cognition. Decision-making is an essential cognitive ability that some forms of it are altered following social exclusion. However, how intertemporal decision-making is influenced by social exclusion is scarcely studied. Here, using Future Life Alone paradigm we demonstrated that experiencing social exclusion increases temporal discounting. We further tested whether the increased temporal discounting is mediated by either time perception or risk-taking. Our results revealed that although time perception is influenced by social exclusion, neither time perception nor risk-taking mediated the changes in temporal discounting. Our results are providing further evidence corroborating that social exclusion evokes cognitive deconstruction and therefore alters temporal discounting.

Ostracism modulates children's recognition of emotional facial expressions

Ostracism has been shown to induce considerable physiological, behavioral and cognitive changes in adults. Previous research demonstrated its effects on children's cognitive and behavioral abilities, but less is known about its impact on their capacity to recognize subtle variations in social cues. The present study aimed at investigating whether social manipulations of inclusion and ostracism modulate emotion recognition abilities in children, and whether this modulation varies across childhood. To do so, 5- and 10-year-old children participated in a computer-based ball tossing game called Cyberball during which they were either included or ostracized. Then, they completed a facial emotion recognition task in which they were required to identify neutral facial expressions, or varying levels of intensity of angry and fearful facial expressions. Results indicated lower misidentification rates for children who were previously ostracized as compared to children who were previously included, both at 5 and 10 years of age. Moreover, when looking at children's accuracy and sensitivity to facial expressions, 5-year-olds' decoding abilities were affected by the social manipulation, while no difference between included and ostracized participants was observed for 10-year-olds. In particular, included and ostracized 10-year-old children as well as ostracized 5-year-olds showed higher accuracy and sensitivity for expressions of fear as compared to anger, while no such difference was observed for included 5-year-olds. Overall, the current study presents evidence that Cyberball-induced inclusion and ostracism modulate children's recognition of emotional faces.

Motivated Social Affordance Judgments of Humor Styles

Despite the ingratiating function of humor, not all humor is created equal. Individual differences in humor styles may inform perceptions of whether prospective group members afford affiliative opportunities, with affiliative humor being regarded as especially beneficial. In this research, we tasked participants with evaluating social targets espousing different humor styles to identify these targets' abilities satisfy and impede both affiliative and social goals (Study 1) while determining if individual differences in these motives foster heightened preferences (Study 2). Affiliative and self-enhancing humor afforded the most affiliative and self-protection opportunities, whereas aggressive humor afforded more threats. Additionally, higher need to belong heightened preferences for affiliative humor. Results provide evidence for assortative sociality in the identification of optimum group members based on humor displays.

A boost in self-esteem after positive social evaluation predicts social and non-social learning

Fluctuations in self-esteem resulting from social acceptance and rejection could guide social behaviour by putting us in a state that is more or less open to social experiences. However, it remains unclear whether social acceptance and rejection may shape learning from social information depending on individual differences in self-esteem changes. Here we used a social feedback paradigm to manipulate social acceptance and rejection in a between-subjects design. Subsequently, we administered a behavioural task that enables the assessment of how well individuals learn on the basis of own experiences versus social information. Participants receiving positive (N = 43) versus negative (N = 44) social evaluation demonstrated an increase in subjective self-esteem. Importantly, the effect of the social evaluation on social learning was moderated by self-esteem changes. Specifically, an increase in self-esteem, as induced by positive evaluation, was associated with increased learning from social, but decreased learning from individual information. A decrease in self-esteem in response to negative evaluation was associated with decreased learning from individual information. These data suggest that increases in self-esteem in response to positive evaluation can induce a shift in the inclination to use social versus non-social information and may open one up to constructive learning from others.

Affective and cognitive impact of social overinclusion: a meta-analytic review of cyberball studies

Belongingness is a central biopsychosocial system. Challenges to belongingness (i.e. exclusion/ostracism) engender robust negative effects on affect and cognitions. Whether overinclusion - getting more than one's fair share of social attention - favourably impacts affect and cognitions remains an open question. This pre-registered meta-analysis includes twenty-two studies (N = 2757) examining overinclusion in the context of the Cyberball task. We found that the estimated overall effect size of overinclusion on positive affect was small but robust, and the effect on fundamental needs cognitions (belongingness, self-esteem, meaningful existence and control) was moderate in size and positive in direction. Notably, the effect sizes of overinclusion were smaller than the corresponding effects of exclusion. Finally, the effects of overinclusion on positive affect were greater for high, as compared to low, socially anxious individuals. Exploring the sequelae of the full range of inclusion experiences - from exclusion to overinclusion - may enrich our understanding of the functioning of the belongingness system as well as its interaction with another central biosocial system - the social status system.

An examination of dispositional social needs, agent knowledge, and two dimensions of product anthropomorphism: A serial mediation model

Thriving attention has been paid to the process and concept of anthropomorphism in marketing literature, as the concept is considered to be a precursor of positive marketing outcomes. However, prior studies have not clarified the position or role of inductive reasoning and anthropomorphism or explained the relationship between anthropomorphism and consumers' individual dispositions. This paper aims to delve into the relationship between consumer psychological and dispositional motivational traits for a given product advertisement that has been personified and imbued with human body features. Building on the literature, a conceptual model has been proposed in which the psychological process-agent knowledge and dispositional motivation to meet social needs have been taken as independent variables positively related to one another and also related individually to the two distinct dimensions of anthropomorphism (i) physical anthropomorphism and (ii) anthropomorphic thinking. Furthermore, it was empirically tested if these two dimensions and these independent variables are linked in a sequential manner. The results show that the need for belonging is positively associated with agent knowledge acquisition, physical anthropomorphism, and anthropomorphic thinking for a given stimulus. Similarly, agent knowledge induced by a humanized stimulus was also positively associated with the two dimensions of anthropomorphism. Furthermore, the two dimensions had a positive relationship with one another. Finally, the need for belonging is also positively associated with agent knowledge and two dimensions of anthropomorphism in a sequential manner. Findings indicate that marketers need to take into account dispositional and psychological factors which might ultimately affect their anthropomorphic inferences in order to induce anthropomorphic thinking because of which positive marketing outcomes take place.

Hostility bias or sadness bias in excluded individuals: does anodal transcranial direct current stimulation of right VLPFC vs. left DLPFC have a mitigating effect?

Exclusion has multiple adverse effects on individual's well-being. It induces anger and hostile cognitions leading to aggressive behavior. The purpose of this study was to test whether exclusion would affect recognition of anger on ambivalent faces of the excluders. We hypothesized that exclusion would elicit more anger encoding (hostility bias) than inclusion, but this effect would be mitigated by anodal tDCS of right VLPFC or left DLPFC-regions engaged in negative affect regulation. Participants (N = 96) were recognizing emotions (anger, sadness, happiness) on ambiguous faces of individuals who-as they were told-liked them or not. Results showed that exclusion induced more sadness bias. tDCS to VLPFC decreased anger and increased sadness recognition on excluders' faces compared with includers' faces, expressing a mixture of these two emotions. Additionally, stimulation to VLPFC and DLPFC decreased latencies for faces expressing sadness (sad-angry and happy-sad) but increased for happy-angry faces. Stimulation to VLPFC also increased reaction time to excluders faces while stimulation of DLPFC decreased reaction latency to includers faces. Results were discussed with the reference to the form of exclusion, motivational mechanism affected by disliking but also to lateralization (valence vs. arousal theory) and cortical regions engaged in encoding sadness after a threat to belonging.

Challenges in detecting proximal effects of existential threat on lie detection accuracy

The present work documents our investigation of proximal (i.e., immediate) effects of existential threat on the process of lie detection. Specifically, we hypothesized that lie detection accuracy will be higher in a mortality salience (MS) condition compared with the control condition. In two lab-based studies (N = 120; N = 109) and one internet study (N = 1294), we did not find any evidence for this hypothesis, that is, MS effects on lie detection accuracy were constantly not significant. However, these null findings should not be overstated. Instead, the present contribution aims to reveal the theoretical and methodological challenges in properly testing proximal MS effects on lie detection accuracy. First, we make transparent that our theoretical assumptions regarding the underlying mechanisms changed during the research process from MS-induced vigilance (Studies 1 and 2) to MS-induced negative affect (Study 3) and remain speculative. Moreover, we show how and why we adapted the operationalization from study to study to optimize adequate testing of the idea. In sum, this work aims to be informative for conducting future research rather than to provide conclusive evidence against or in favor of the investigated idea.

Facing social exclusion: a facial EMG examination of the reaffiliative function of smiling

Social exclusion influences how expressions are perceived and the tendency of the perceiver to mimic them. However, less is known about social exclusion's effect on one's own facial expressions. The aim of the present study was to identify the effects of social exclusion on Duchenne smiling behaviour, defined as activity of both zygomaticus major and the orbicularis oculi muscles. Utilising a within-subject's design, participants took part in the Cyberball Task in which they were both included and excluded while facial electromyography was measured. We found that during the active experience of social exclusion, participants showed greater orbicularis oculi activation when compared to the social inclusion condition. Further, we found that across both conditions, participants showed greater zygomaticus major muscle activation the longer they engaged in the Cyberball Task. Order of condition also mattered, with those who experienced social exclusion before social inclusion showing the greatest overall muscle activation. These results are consistent with an affiliative function of smiling, particularly as social exclusion engaged activation of muscles associated with a Duchenne smile.

Social Context and Rejection Expectations Modulate Neural and Behavioral Responses to Social Feedback

When meeting other people, some are optimistic and expect to be accepted by others, whereas others are pessimistic and expect mostly rejections. How social feedback is evaluated in situations that meet or do not meet these biases and how people differ in their response to rejection and acceptance depending on the social situation are unknown. In this study, participants experienced rejection and acceptance by peers in two different social contexts, one with high (negative context) and the other with low probability of rejection (positive context). We examined how the neural and behavioral responses to rejection are altered by this context and whether it depends on the individual's sensitivity to rejection. Behavioral results show that, on average, people maintain an optimistic bias even when mostly experiencing rejection. Importantly, personality differences in rejection sensitivity affected both prior expectations to be rejected in the paradigm and the extent to which expectations changed during the paradigm. The context also strongly modulated ERPs and theta responses to rejection and acceptance feedback. Specifically, valence effects on neural responses were enhanced in the negative context, suggesting a greater relevance to monitor social feedback in such a situation. Moreover, midfrontal theta predicted how expectations were changed in response to prediction errors, stressing a role for theta in learning from social feedback. Surprisingly, interindividual differences in rejection sensitivity did not affect neural responses to feedback. Our results stress the importance of considering the interaction between subjective expectations and the social context for behavioral and neural responses to social rejection.

Touched by loneliness-how loneliness impacts the response to observed human touch: a tDCS study

Lonely people often crave connectedness. However, they may also experience their environment as threatening, entering a self-preserving state that perpetuates loneliness. Research shows conflicting evidence about their response to positive social cues, and little is known about their experience of observed human touch. The right inferior frontal gyrus (rIFG) is part of an observation-execution network implicated in observed touch perception. Correlative studies also point to rIFG's involvement in loneliness. We examined the causal effect of rIFG anodal transcranial direct current stimulation on high- and low-loneliness individuals observing human touch. In a cross-over design study, 40 participants watched pictures of humans or objects touching or not touching during anodal and sham stimulations. Participants indicated whether pictures contained humans or objects, and their reaction time was measured. Results show that the reaction time of low-loneliness individuals to observed human touch was significantly slower during anodal stimulation compared to high-loneliness individuals, possibly due to them being more emotionally distracted by it. Lonely individuals also reported less liking of touch. Our findings support the notion that lonely individuals are not drawn to positive social cues. This may help explain the perpetuation of loneliness, despite social opportunities that could be available to lonely people.

Social threat indirectly increases moral condemnation via thwarting fundamental social needs

Individuals who experience threats to their social needs may attempt to avert further harm by condemning wrongdoers more severely. Three pre-registered studies tested whether threatened social esteem is associated with increased moral condemnation. In Study 1 (N = 381) participants played a game in which they were socially included or excluded and then evaluated the actions of moral wrongdoers. We observed an indirect effect: Exclusion increased social needs-threat, which in turn increased moral condemnation. Study 2 (N = 428) was a direct replication, and also showed this indirect effect. Both studies demonstrated the effect across five moral foundations, and was most pronounced for harm violations. Study 3 (N = 102) examined dispositional concerns about social needs threat, namely social anxiety, and showed a positive correlation between this trait and moral judgments. Overall, results suggest threatened social standing is linked to moral condemnation, presumably because moral wrongdoers pose a further threat when one's ability to cope is already compromised.

Perceiving faces through reconnection-colored glasses after social exclusion: Evidence from N100

Social exclusion motivates individuals to selectively reconnect with others, in which face categorization plays an important role. However, it remains unknown how reconnection possibility interacts with perception at the very early stage of face categorization. To address this issue, after social exclusion or social inclusion priming, participants were instructed to select one person from two gender-matched strangers as a future "coworker" (with high reconnection possibility; the left one is a future "stranger," with low reconnection possibility) for another ostensible task, and then complete an orientation judgment task of self-face, coworker face and stranger face, with event-related brain potential (ERP) recordings. Results showed that excluded participants produced larger N100 to future coworker face than to stranger face, but no such difference was found among included participants. Compared with included participants, excluded participants produced significantly larger N100 to future coworker face. Moreover, N100 elicited by future coworker face was significantly negatively correlated with rating scores of exclusion only for social excluded participants. These findings indicate that social reconnection desire may contribute to the biased face perception which facilitates face categorization of socially excluded people.

Social exclusion enhances affiliative signaling

Reciprocating smiles is important for maintaining social bonds as it both signals affiliative intent and elicits affiliative responses. Feelings of social exclusion may increase mimicry as a means to regulate affiliative bonds with others. In this study, we examined whether feelings of exclusion lead people to selectively reciprocate the facial expressions of more affiliative-looking people. Participants first wrote about either a time they were excluded or a neutral event. They then classified 20 smiles-half spontaneous smiles and half posed. Facial electromyography recorded smile muscle activity. Excluded participants distinguished the two smile types better than controls. Excluded participants also showed greater zygomaticus major (mouth smiling) activity toward enjoyment smiles compared to posed smiles; control participants did not. Orbicularis oculi (eye crinkle) activity matched that of the smile type viewed, but did not vary by exclusion condition. Affiliative social regulation is discussed as a possible explanation for these effects.

Regulatory focus and social reconnection following social exclusion

Promotion- and prevention-focused people are differentially sensitive to situational gains and losses, thus we reasoned that people's state regulatory focus following social exclusion should influence whether a social reconnection opportunity is perceived as safe (i.e., will exclusion persist or abate). To create an exclusion condition, all participants believed that other ostensible participants read their personal essay and chose not to work with them (i.e., all participants were excluded). Following the exclusion, participants rated how much they wanted to work with a new partner whose personality was depicted as a safe or unsafe reconnection opportunity. We expected and found that participants who held a prevention focus were willing to work with the partner, but only when the opportunity was perceived as safe. By comparison, participants who held a promotion focus were willing to work with the partner regardless of the opportunity's safety. The relationship between social reconnection safety and regulatory focus and its effect on social reconnection efforts is discussed.

A Decision Architecture for Safety Computations

Accurately estimating safety is critical to pursuing nondefensive survival behaviors. However, little attention has been paid to how the human brain computes safety. We conceptualize a model that consists of two components: (i) threat-oriented evaluations that focus on threat value, imminence, and predictability; and (ii) self-oriented evaluations that focus on the agent's experience, strategies, and ability to control the situation. Our model points to the dynamic interaction between these two components as a mechanism of safety estimation. Based on a growing body of human literature, we hypothesize that distinct regions of the ventromedial prefrontal cortex (vmPFC) respond to threat and safety to facilitate survival decisions. We suggest safety is not an inverse of danger, but reflects independent computations that mediate defensive circuits and behaviors.

Demographic effects on facial emotion expression: an interdisciplinary investigation of the facial action units of happiness

Understanding demographic difference in facial expression of happiness has crucial implications on social communication. However, prior research on facial emotion expression has mostly focused on the effect of a single demographic factor (typically gender, race, or age), and is limited by the small image dataset collected in laboratory settings. First, we used 30,000 (4800 after pre-processing) real-world facial images from Flickr, to analyze the facial expression of happiness as indicated by the intensity level of two distinctive facial action units, the Cheek Raiser (AU6) and the Lip Corner Puller (AU12), obtained automatically via a deep learning algorithm that we developed, after training on 75,000 images. Second, we conducted a statistical analysis on the intensity level of happiness, with both the main effect and the interaction effect of three core demographic factors on AU12 and AU6. Our results show that females generally display a higher AU12 intensity than males. African Americans tend to exhibit a higher AU6 and AU12 intensity, when compared with Caucasians and Asians. The older age groups, especially the 40–69-year-old, generally display a stronger AU12 intensity than the 0–3-year-old group. Our interdisciplinary study provides a better generalization and a deeper understanding on how different gender, race and age groups express the emotion of happiness differently.

Does Social Exclusion Improve Detection of Real and Fake Smiles? A Replication Study

Research on social exclusion suggests an increased attention of excluded persons to subtle social cues. In one study (N = 32), published in Psychological Science, Bernstein et al. (2008) provided evidence for this idea by showing that participants in the social exclusion condition were better in correctly categorizing a target person’s smile as real or fake. Although highly cited, this finding has never been directly replicated. The present study aimed to fill that gap. 201 participants (79.1% female) were randomly assigned to a social exclusion, social inclusion or control condition. Next, participants watched 20 videos of smiling persons and rated whether they show a real or a fake smile. In line with the original study, results showed that participants in the exclusion condition performed better than in the control condition. However, the performance did not differ between the exclusion and inclusion condition—although the pattern was in the predicted direction. In sum, the findings of our study increase rather than decrease confidence in the validity of the investigated idea, but results point to a substantially smaller effect.

Duchenne Smiles as Honest Signals of Chronic Positive Mood

Chronic positive mood (CPM) has been shown to confer a wide variety of social, functional, and health benefits. Some researchers have argued that humans evolved to feel CPM, which explains why most people report better than neutral mood (the “positivity offset bias”) and why particularly happy people have particularly good outcomes. Here, we argue that the Duchenne smile evolved as an honest signal of high levels of CPM, alerting others to the psychological fitness of the smiler. Duchenne smiles are honest because they express felt positive emotion, making it difficult for unhappy people to produce them. Duchenne smiles enable happy people to signal and cooperate with one another, boosting their advantages. In our literature review, we found (a) that not all Duchenne smiles are “honest,” although producing them in the absence of positive emotion is difficult and often detectable, and (b) that the ability to produce and recognize Duchenne smiles may vary somewhat by a person’s cultural origin. In the final section of the article, we consider behavioral influences on CPM, reviewing research showing that engaging in eudaimonic activity reliably produces CPM, as posited by the eudaimonic-activity model. This research suggests that frequent Duchenne smiling may ultimately signal eudaimonic personality as well as CPM.

Acting Surprised: Comparing Perceptions of Different Dynamic Deliberate Expressions

People are accurate at classifying emotions from facial expressions but much poorer at determining if such expressions are spontaneously felt or deliberately posed. We explored if the method used by senders to produce an expression influences the decoder’s ability to discriminate authenticity, drawing inspiration from two well-known acting techniques: the Stanislavski (internal) and Mimic method (external). We compared spontaneous surprise expressions in response to a jack-in-the-box (genuine condition), to posed displays of senders who either focused on their past affective state (internal condition) or the outward expression (external condition). Although decoders performed better than chance at discriminating the authenticity of all expressions, their accuracy was lower in classifying external surprise compared to internal surprise. Decoders also found it harder to discriminate external surprise from spontaneous surprise and were less confident in their decisions, perceiving these to be similarly intense but less genuine-looking. The findings suggest that senders are capable of voluntarily producing genuine-looking expressions of emotions with minimal effort, especially by mimicking a genuine expression. Implications for research on emotion recognition are discussed.

Does It Matter What I Say? Using Language to Examine Reactions to Ostracism as It Occurs

Most of our knowledge related to how social exclusion affects those who ostracize and those who are being ostracized is based on questionnaires administered after the ostracism situation is over. In this research, we strived to further our understanding of the internal dynamics of an ostracism situation. We therefore examined individuals' language-specifically, function words-as a behavior indicative of psychological processes and emergent states that can be unobtrusively recorded right in the situation. In online chats, 128 participants talked about a personal topic in groups of three. In the experimental group (n = 79), two conversation partners ignored every contribution by the third. We found that, compared to the control group, these targets of ostracism used language indicative of a self-focus and worsened mood, but not of social focus or positivity, although positivity was related to a writer's likeability. Sources of ostracism used language suggesting that they were distancing themselves from the situation, and they further engaged in victim derogation. We discuss how our results highlight the severity and potential self-sustainability of ostracism.

The affiliative consequences of same-race and cross-race mimicry

Few studies have replicated and extended the classic mimicry → liking effect. The present research sought to (a) replicate the affiliative consequences of mimicry; (b) test whether the affiliative consequences hold in a context where mimicry may not be normative (i.e., cross-race interactions); and (c) investigate how excluded individuals respond to same- versus cross-race mimicry and non-mimicry. Participants wrote about a control topic or social exclusion and then engaged in a brief laboratory interaction in which they were mimicked or not mimicked by a confederate who was either same-race or cross-race. Then they reported how much they liked the confederate. Within the control condition, the effect of mimicry on affiliation depended on the race of the confederate - but this pattern did not emerge for excluded individuals. The study was unable to conclusively replicate and extend previous findings. The authors make recommendations to promote a more cumulative science of behavioral mimicry.

Social exclusion modulates dual mechanisms of cognitive control: Evidence from ERPs

Many studies have investigated how social exclusion influences cognitive control but reported inconsistent findings. Based on the dual mechanisms of control framework, this study investigated how social exclusion influences proactive and reactive modes of control (Experiment 1) and the underlying mechanisms (Experiment 2). The Cyberball game was used to manipulate social exclusion. Eighty-six female participants (about 40 for each experiment) performed cognitive control tasks while event-related potentials were recorded. In Experiment 1, an AX Continuous Performance Task (AX-CPT) was adopted to differentiate between proactive and reactive control. Results showed that social exclusion weakened proactive control but enhanced reactive control, as reflected by the weaker proactive control indicators (i.e., P3b and CNV), but strengthened reactive control indicators (accuracy and N2) in excluded individuals. More importantly, in Experiment 2, through varying in whether task cues were available before or after target onset in a cued-flanker task, we further manipulated the possibility of engaging proactive control, and found the weakened proactive control could be attributed to both impaired cognitive ability and lowered motivation to engage proactive control in excluded individuals. Together, these results provide insight on how social exclusion influences cognitive control and suggest promising implications for designing effective interventions to relieve the negative impact of social exclusion.

Social anxiety and the interpretation of morphed facial expressions following exclusion and inclusion

BACKGROUND AND OBJECTIVES

Negative interpretation biases are postulated to play etiological and maintaining roles in social anxiety (SA). However, empirical support for interpretation biases of facial expression in SA is inconsistent. Given the importance of signals of (dis)approval in SA, our objective was to examine whether SA is associated with enhanced sensitivity to such signals especially following exclusion.

METHODS

In Study 1, participants (N = 139) underwent an exclusion/inclusion manipulation and were then presented with video clips of smiles gradually changing into disgust expressions (smile-to-disgust). In Study 2 (N = 203), participants saw smile-to-disgust as well as disgust-to-smile clips following an exclusion/inclusion manipulation. Participants' task in both studies was to detect the offset of the initial expression.

RESULTS

Results of Study 1 show that detection latency of smiles' disappearance is negatively associated with SA severity. The results of Study 2 suggest that this association is stronger following exclusion, and specific to the smile-to-disgust as opposed to the disgust-to-smile, transitions.

LIMITATIONS

Our studies did not examine whether the observed interpretation bias was specific to SA.

CONCLUSIONS

Our findings support and refine cognitive theories of SA, suggesting that interpretation biases for facial information in SA may be especially pronounced following exclusion.

Loneliness Modulates Automatic Attention to Warm and Competent Faces: Preliminary Evidence From an Eye-Tracking Study

Social connections are essential for human survival. Loneliness is a motivational factor for building and maintaining social connections. Automatic attention occurs with little cognitive effort and plays a key role in detecting biologically salient events, such as human faces. Although previous studies have investigated the effect of loneliness on social behavior, the effect of loneliness on automatic attention to human faces remains largely unknown. The present study investigated the effects of loneliness on automatic visual attention to warmth and competence facial information, which determines facial attraction. This study included 43 participants who rated warmth and competence facial information. Then, they engaged with the target-distractor paradigm in which they saw two house images at the top and bottom and indicated whether the images were identical. During the task, we presented two faces as distractors and measured visual attention toward the faces as automatic attention because participants did not have to attend to the faces. The results showed an interactive effect between subjective loneliness and facial information on automatic attention. Warm targets automatically captured the attention of people feeling relatively lonely, whereas competent targets automatically captured the attention of those who felt less lonely. These results suggest that loneliness adaptively influences automatic processing of social information.

Effects of rejection intensity and rejection sensitivity on social approach behavior in women

Objective

Perceived rejection plays an important role for mental health and social integration. This study investigated the impact of rejection intensity and rejection sensitivity on social approach behavior.

Method

121 female participants were randomly assigned to one of three conditions differing in the degree of induced rejection (inclusion, medium rejection, severe rejection). Thereafter they were asked to interact with an unknown person during a touch-based cooperative task.

Results

Participants high in rejection sensitivity sought significantly less physical contact than participants low in rejection sensitivity. Individuals in the medium rejection condition touched their partners more often than those in the included condition, while no difference between included and severely rejected participants could be observed.

Conclusions

The results suggest that the intensity of rejection matters with regard to coping. While participants in the medium intensity rejection condition aimed to ‘repair’ their social self by seeking increased contact with others, severely rejected participants did not adapt their behavior compared to included participants. Implications for therapy are discussed.

Beliefs in Conspiracy Theories Following Ostracism

Four studies (total valid N = 643) examined whether ostracism increases people's political conspiracy beliefs through heightened vulnerability and whether self-affirmation intervention counteracts the effect of ostracism on conspiracy beliefs. Compared with their nonostracized counterparts, ostracized participants were more likely to endorse conspiracy beliefs related to different political issues (Studies 1-3). Moreover, heightened vulnerability mediated the link between ostracism and conspiracy beliefs (Studies 1-3). Offering ostracized participants an opportunity to reaffirm values important to them could reduce their political conspiracy beliefs (Study 4). Taken together, our findings highlight the crucial role of vulnerability in understanding when and why ostracism increases conspiracy beliefs and how to ameliorate this relationship. Our findings also provide novel insights into how daily interpersonal interactions influence people's political beliefs and involvement.

Putting Belonging in Context: Communal Affordances Signal Belonging in STEM

A sense of belonging in a particular context is cued not only by the people in the role but by the affordances of the role-that is, the opportunities for goal pursuit. We investigate this role-based belonging in four studies documenting that the perceived affordances of social roles inform sense of belonging and convey known benefits of belonging. Perceiving more communal opportunities in naturalistic science, technology, engineering, and mathematic (STEM) settings was associated with heightened belonging in those roles (Studies 1-2). Experimentally manipulating collaborative activities in a science lab increased anticipated belonging in the lab and fostered interest, particularly among women (Study 3). Finally, mentally simulating communal affordances in a role promoted recovery from belonging threat: Considering communal opportunities in STEM facilitated recovery of STEM-specific belonging after recalling exclusion in STEM (Study 4). Investigations of role-based belonging offer the potential for both theoretical and practical advances.

The Impact of Thwarted Belonging on Tolerance of Abusive Behaviors in a Romantic Relationship

Introduction: This work examined the role of thwarted belonging in directing reactions to intimate partner violence (IPV). We tested two competing hypotheses. First, we offered the Insensitivity Hypothesis, which argued that excluded (compared to control) participants would indicate they were comfortable and willing to remain in an abusive relationship longer, an effect likely mediated by reduced relational needs. Second, we offered the Hypersensitivity Hypothesis, which argued that excluded (compared to control) participants would indicate they were uncomfortable and willing to leave an abusive relationship earlier, an effect likely mediated by activation of hostile cognitions.

Methods: To test these, female participants underwent an exclusion or non-exclusion experience, completed measures of the hypothesized mediators, and then read a vignette describing a heterosexual romantic relationship that slowly turned more abusive. Participants took the perspective of the female victim and indicated when they would feel uncomfortable in the relationship and leave the relationship.

Results: Results partially supported the Insensitivity Hypothesis, as exclusion (relative to control) lowered relational needs, and lowered relational needs predicted later desires to exit the relationship (no significant effects emerged for discomfort onset).

Discussion: Implications of these findings for the belonging and IPV literatures are discussed.

Reconsidering the Duchenne Smile: Indicator of Positive Emotion or Artifact of Smile Intensity?

The Duchenne smile hypothesis is that smiles that include eye constriction (AU6) are the product of genuine positive emotion, whereas smiles that do not are either falsified or related to negative emotion. This hypothesis has become very influential and is often used in scientific and applied settings to justify the inference that a smile is either true or false. However, empirical support for this hypothesis has been equivocal and some researchers have proposed that, rather than being a reliable indicator of positive emotion, AU6 may just be an artifact produced by intense smiles. Initial support for this proposal has been found when comparing smiles related to genuine and feigned positive emotion; however, it has not yet been examined when comparing smiles related to genuine positive and negative emotion. The current study addressed this gap in the literature by examining spontaneous smiles from 136 participants during the elicitation of amusement, embarrassment, fear, and pain (from the BP4D+ dataset). Bayesian multilevel regression models were used to quantify the associations between AU6 and self-reported amusement while controlling for smile intensity. Models were estimated to infer amusement from AU6 and to explain the intensity of AU6 using amusement. In both cases, controlling for smile intensity substantially reduced the hypothesized association, whereas the effect of smile intensity itself was quite large and reliable. These results provide further evidence that the Duchenne smile is likely an artifact of smile intensity rather than a reliable and unique indicator of genuine positive emotion.

The subjective value of a smile alters social behaviour

Face-to-face social behaviour is difficult to explain, leading some researchers to call it the “dark matter” of psychology/neuroscience [1]. We apply an idea from neuroeconomics to this problem, suggesting that how people subjectively value facial expressions should predict usage differences during unconstrained interaction. Specifically, we ask whether the subjective value of smiles is malleable as a consequence of immediate social experience and how this relates to smiling during face-to-face interactions. We measured the value of a smile in monetary terms and found that increases in people’s social neediness caused devaluation of polite smiles but no changes in how they valued genuine smiles. This result predicts that participants induced to feel high levels of social need should be less responsive to their social partners’ polite smiles in a subsequent unconstrained social interaction. As expected, high social-need participants returned fewer polite smiles when interacting with a partner, leading to poor interaction outcomes. Genuine smile reciprocity remained unchanged. Findings show that social states influence real-world interactions by changing social-cue valuation, highlighting a potential mechanism for understanding the moment-to-moment control of social behaviour and how behaviour changes based on people’s subjective evaluations of the social environment.

Situational Factors Influencing Receptivity to Bullshit

Individuals are motivated to maintain a sense of meaning, and enact cognitive processes to do so (e.g., perceiving structure in the environment). This motivation to find meaning may ultimately impact humans’ interpretation of "bullshit", statements intended to convey profundity without any meaning. Conversely, subtle cues threatening the meaningfulness of bullshit may elicit greater skepticism. Three studies tested situational factors predicted to heighten or diminish susceptibility to bullshit by changing motivations to seek meaning. We employed diverse methods including symbolic meaning threat (Study 1), social exclusion (Cyberball; Study 2), and manipulating cognitive fluency (Study 3). Taken together, the results indicate basic processes shaping the detection of meaning have implications for the appraisal of ambiguously insightful information.

When and Why Being Ostracized Affects Veracity Judgments

Ostracism—being ignored and excluded by others—is a ubiquitous experience with adverse effects on well-being. To prevent further exclusion and regain belonging, ostracized individuals are well advised to identify affiliation partners who are sincerely well-disposed. Humans’ ability to detect lies, however, is generally not very high. Yet, veracity judgments can become more accurate with decreasing reliance on common stereotypic beliefs about the nonverbal behavior of liars and truth-tellers. We hypothesize that ostracized (vs. included) individuals base their veracity judgments less on such stereotypical nonverbal cues if message content is affiliation-relevant. In line with this hypothesis, Experiment 1 shows that ostracized (vs. included) individuals are better at discriminating affiliation-relevant lies from truths. Experiments 2 and 3 further show that ostracized (vs. included) individuals base their veracity judgments less on stereotypical nonverbal cues if messages are of high (but not low) affiliation relevance.

“You’re such a pain!”: Investigating how psychological pain influences the ostracism of a burdensome group member

Maintaining social relationships with others is essential for survival, but not all relationships are beneficial. Individuals exclude nonbeneficial burdensome group members, those who encumber group success. We investigated whether feeling psychological pain is a mechanism that prompts assessment of social threats―potentially putting the “brakes” on burdensome (nonbeneficial) relationships. Specifically, we investigated if interacting with burdensome individuals caused others to experience psychological pain, negative affect, and to dislike the burdensome individual. Across 5 studies, using 3 different paradigms, we found those who interacted with a burdensome individual experienced psychological pain, which influenced ostracizing (excluding and ignoring) the burdensome group member. In Studies 4 and 5, we found psychological pain mediated the relationship between burdensomeness and ostracism even when we accounted for negative affect and dislike of the burdensome individual. Our results suggest psychological pain can guide social interactions and should be the subject of future research involving social threat.

Feeling Hurt: Revisiting the Relationship Between Social and Physical Pain

Pain overlap theory has generated decades of controversy and still receives considerable research attention. A major advance has been the revelation that social and physical pain activate similar neural regions, providing suggestive evidence of a “piggybacked” alarm system that coevolved to detect social exclusion. Recent developments, however, have brought neural evidence for pain overlap into question. We analyze these developments from a social psychological perspective and identify the need for a reformulated approach. To meet this need, we provide a framework that a priori predicts generalized overlap and specific divergence across a range of biopsychosocial domains. The framework points to a functional pattern for similarities and differences, which can be utilized to generate testable hypotheses so that the field can move forward. To demonstrate the utility and promise of the framework, we identify key hypotheses relating to attention, motivation, and responses to pain, and review research relevant to these hypotheses.

Turning Away From Averted Gazes: The Effect of Social Exclusion on Gaze Cueing

Past studies showed increased sensitivity to other people’s gaze after social exclusion. In the present research, across two studies, we tested whether social exclusion could affect the basic cognitive phenomenon of gaze-cueing effect, namely, the tendency to redirect visual attention to the same location that other people are looking at. To this purpose, participants were socially excluded or included using the Cyberball manipulation. In Study 1, after the manipulation, participants performed a gaze-cueing task in which an individual’s gaze, oriented rightward or leftward, preceded a peripheral target stimulus requiring a simple categorization response. The gaze direction could be congruent or incongruent with the location of the target. Results revealed a reduced gaze-cueing effect for socially excluded than for socially included participants. In Study 2, where human gazes were replaced by arrow cues, such an interaction between social exclusion and trial congruency disappeared, indicating a specific effect of social stimuli. We interpreted these findings with the notion that excluded participants can perceive an averted gaze as a further sign of social exclusion, thus showing a reduced gaze-cueing effect.

Social exclusion reduces the sense of agency: Evidence from intentional binding

Social exclusion is known to induce an immediate threat to one's perceived sense of control. The sense of agency is an important human experience, strongly associated with volitional action. Healthy participants perceive the temporal interval between a voluntary action and its effect to be shorter than the same interval when it separates an involuntary action and effect. This temporal illusion is known as intentional binding and is used experimentally to index the implicit sense of agency. The current study investigated whether activating memories of social exclusion alters intentional binding. Results show that action-effect interval estimates are significantly longer after remembering an episode of social exclusion than after remembering an episode of social inclusion, or a no priming baseline condition. This study is the first to demonstrate the link between feelings of social exclusion and the pre-reflective sense of agency.
