Psychophysiological distinctions in emotional responding: sensitivity to perceiving loss of connection.

Emotion involves oneself in relation to a subject of attention; e.g., sadness is to be sad about something/someone. This study examined emotional responses to perceiving a loss of connection from oneself. Evidence suggests that Europeans tend to perceive salient objects in the foreground, while East Asians are more likely to perceive holistically, considering the interrelationships between the context and the object. We studied how this distinction affected European Americans' (EA) and Chinese Americans' (CA) sensitivity to perceiving the loss of connection. Both groups were exposed to loss by playing Cyberball, a ball-tossing video game, and then watched a film clip on grief. We hypothesized that EA would respond with increasing heart rate (HR) variance around the mean when perceiving loss. CA were predicted to show no difference from controls. We also hypothesized that EA would feel sadder, in terms of decreased HR and increased respiratory sinus arrhythmia (RSA), earlier during the film clip. In total, 53 subjects were recruited, of which 40 were EA (47.5% women, age 21.08 ± 1.94 years) and 13 were CA (61.5% women, age 21.05 ± 1.74 years); 25 subjects (19 EA, 6 CA) received 2 out of 48 balls tossed in Cyberball and the controls received 10. ECG, respiration, and facial electromyography (fEMG) data were acquired. The results during Cyberball showed that EA's HR variance relative to baseline (HR SDc/b) had an upward trend on perceiving loss. Contrary to prediction, CA also showed higher levels of HR variance relative to baseline. The ANOVA of HR SDc/b revealed that the interaction effect of two factors, time and condition, was statistically significant (p = 0.009). However, as predicted, EA in the experimental condition had decreased HR and increased RSA, a sign of withdrawal in sadness, 30 to 60 s into the sad clip. fEMG data at the corrugator muscle revealed that EA activated higher peak intensity 5.5 s earlier than CA (increased 1.571 vs. 0.844). This difference, however, was not statistically significant. The evidence suggests that increased exposure to loss automatically led to increased HR variance in both groups even when subjects were informed that players were computer-generated. However, the effect was stronger on EA to increase their arousal and sensitivity to grief thereafter.

Examining the causal effects of social exclusion on shame and dissociative detachment.

BACKGROUND AND OBJECTIVES: Dissociative detachment experiences (e.g., derealization, absorption) underpin much psychopathology and are often researched in relation to co-occurring affective states such as shame, the latter being known to occur in situations involving actual or perceived negative social evaluation. The association between shame and dissociative detachment may also be moderated by individual differences in people's need to belong. The goal of the present study was to experimentally investigate the effects of social exclusion on shame and dissociative detachment depending on perceivers' need to belong. METHODS: After measuring individual differences in need to belong and shame proneness, the Cyberball paradigm was utilized to communicate either social inclusion or exclusion. Following Cyberball, a sample of 281 participants completed measures of state shame and state dissociation. RESULTS: Social exclusion increased dissociative detachment, and these effects were mediated by increases in state shame. These effects were particularly evident among people with a high need to belong. LIMITATIONS: Other individual differences such as rejection sensitivity may also moderate the relationship between exclusion and shame. While Cyberball can be used to investigate shame, it can only induce shame via social exclusion, whereas shame can also be elicited in other ways such as performance failure. CONCLUSIONS: Social exclusion can elicit shame, which is most acutely felt by those with a strong need to belong, and this aversive experience appears to be managed by dissociative detachment.

The smallest things make me emotional! Emotion reactivity in non-suicidal self-injury: trait, state, and physiological differences.

Objective: The current study sought to clarify the role of emotion reactivity in non-suicidal self-injury (NSSI) by examining three forms of emotion reactivity (physiological and self-reported trait and state reactivity) among a sample of young adults with or without a history of NSSI. Materials and methods: Seventy-six adults (M age = 20.97, 73.7% female) participated in a semi-structured clinical interview to determine NSSI history and completed a measure of trait emotion reactivity. Participants then provided state emotion reactivity ratings before and after a social rejection task, recovery period, and positive mood induction while physiological data was continuously recorded. Results: Although individuals with a history of NSSI perceived themselves to be more emotionally reactive, these participants were not more physiologically reactive, nor were their state reactivity ratings significantly different from individuals without a history of NSSI. Discussion: Results suggest increased emotionality in response to a stressor is within normal bounds and not unique to individuals with a history of NSSI, and provide implications for future research on the etiology and treatment of NSSI.

Here Comes Revenge: Peer Victimization Relates to Neural and Behavioral Responses to Social Exclusion.

The aim of this study was to examine whether repeated victimization relates to differential processing of social exclusion experiences. It was hypothesized that experiences of repeated victimization would modulate neural processing of social exclusion in the insula, anterior cingulate cortex, and lateral prefrontal cortex. Furthermore, we hypothesized that repeated victimization relates positively to intentions to punish excluders. Exploratively, associations between neural processing and intentions to punish others were examined. The sample consisted of children with known victimization in the past two years (n = 82 (behavioral) / n = 73 (fMRI), 49.4% girls, Mage = 10.6). The participants played Cyberball, an online ball-tossing game, which was manipulated so that in the first block participants were equally included and in the second block they were excluded from play. Victimization was not related to neural activation during social exclusion, although there were indications that victimization may be related to increased insula activation during explicit exclusion. Behaviorally, repeated victimization was related to more intention to punish excluders. Neural activation during social exclusion did not predict intentions to punish excluders, but results tentatively suggested that increased insula activation during social exclusion may be related to increased intentions to punish. Together, these results provide a replication of earlier Cyberball studies and point toward differential processing of social exclusion by children who are victimized.

Social Exclusion Effect on Self-Efficacy.

Research and theory indicate that self-efficacy can be influenced by factors related to persuasion, experiences of success, and emotional states. These factors can include situations that challenge people's beliefs about their abilities. Social exclusion is associated with deprivation of the need for control, low self-control, and low self-esteem. This study examined whether social exclusion might affect general self-efficacy beliefs. It was predicted that self-efficacy would be lower in the exclusion condition than in the inclusion condition and that satisfaction of the need for control and belonging would mediate the exclusion effect on self-efficacy. Feelings of control and belonging were manipulated using a Cyberball game in which participants were excluded or included in the online ball-tossing game. The results confirmed the hypotheses. Self-efficacy, belonging, and control were lower in ostracism than in the inclusion condition. Control and belonging were positively related to self-efficacy and mediated the effect of ostracism on self-efficacy. Research suggests that creating an environment that satisfies control and relatedness needs may foster self-efficacy and that each need is important.

Automatic detection of facial expressions during the Cyberball paradigm in Borderline Personality Disorder: a pilot study.

Borderline Personality Disorder (BPD) symptoms include inappropriate control of anger and severe emotional dysregulation after rejection in daily life. Nevertheless, when using the Cyberball paradigm, a tossing game to simulate social exclusion, the seven basic emotions (happiness, sadness, anger, surprise, fear, disgust, and contempt) have not been exhaustively tracked out. It was hypothesized that these patients would show anger, contempt, and disgust during the condition of exclusion versus the condition of inclusion. When facial emotions are automatically detected by Artificial Intelligence, "blending", -or a mixture of at least two emotions- and "masking", -or showing happiness while expressing negative emotions- may be most easily traced expecting higher percentages during exclusion rather than inclusion. Therefore, face videos of fourteen patients diagnosed with BPD (26 ± 6 years old), recorded while playing the tossing game, were analyzed by the FaceReader software. The comparison of conditions highlighted an interaction for anger: it increased during inclusion and decreased during exclusion. During exclusion, the masking of surprise; i.e., displaying happiness while feeling surprised, was significantly more expressed. Furthermore, disgust and contempt were inversely correlated with greater difficulties in emotion regulation and symptomatology, respectively. Therefore, the automatic detection of emotional expressions during both conditions could be useful in rendering diagnostic guidelines in clinical scenarios.

Involvement in cyberbullying events and empathy are related to emotional responses to simulated social pain tasks.

Introduction: This study aims to explore the relationship between cyberbullying involvement either as a perpetrator or a victim and emotional responses to virtual social exclusion and inclusion. Previous research has predominantly focused on the impacts of in-person bullying. Our study shifts this focus to the cyber realm. Methods: A total of 156 adolescents living in northern Italy were recruited (Mage: 12.26; SD = 0.87; 43% female). After completing measures of empathy and involvement in cyberbullying, adolescents participated in the cyberball tasks. Latent profile analysis was used to identify subgroups. Results: We found three groups: Class 3, reporting negative responses to the social exclusion tasks and positive responses to the social inclusion tasks; Class 1, reporting neutral emotional responses to social inclusion and negative emotional responses to social exclusion; and Class 2, showing neutral responses to 'social exclusion' tasks and strongly positive responses to 'social inclusion' tasks. Linear regression revealed that cyberbullies report a typical emotional response to exclusion and inclusion tasks (Class 3), whereas cybervictims are more likely to report negative responses to both exclusion and inclusion events (Class 1). High levels of empathy are associated with the manifestation of a typical emotional response (Class 3), in contrast to an impaired emotional response characterized by neutral or positive responses to conditions of 'social exclusion' and positive responses to conditions of 'social inclusion' (Class 2). Conclusion: Results underscore the complex interplay between cyberbullying roles and emotional responses to virtual social experiences. Theoretical implications and limitations of the research are discussed.

Being close or being alone: How Social ostracism affects solitude preference.

Social ostracism refers to the phenomenon of being excluded from social interactions and not being accepted by society. While previous research has examined its impact on prosocial and antisocial behaviour, few studies have investigated how individuals respond to ostracism by seeking solitude. Therefore, our study aims to explore the association between social ostracism and solitude seeking as well as the potential psychological mechanisms involved. We conducted three studies involving 488 Chinese students (59% female) and found that (a) long-term ostracism experiences positively correlated with preference for solitude, (b) short-term ostracism did not immediately lead to solitude seeking but increased the desire to establish new connections with others and (c) hostile assessment and negative emotions played a chain mediation role in the relationship between social ostracism and solitude seeking. These findings provide new insights and empirical evidence for understanding the relationship between social ostracism and solitude-seeking.

Increased anger and stress and heightened connectivity between IFG and vmPFC in victims during social interaction.

Self-identification as a victim of violence may lead to increased negative emotions and stress and thus, may change both structure and function of the underlying neural network(s). In a trans-diagnostic sample of individuals who identified themselves as victims of violence and a matched control group with no prior exposure to violence, we employed a social exclusion paradigm, the Cyberball task, to stimulate the re-experience of stress. Participants were partially excluded in the ball-tossing game without prior knowledge. We analyzed group differences in brain activity and functional connectivity during exclusion versus inclusion in exclusion-related regions. The victim group showed increased anger and stress levels during all conditions. Activation patterns during the task did not differ between groups but an enhanced functional connectivity between the IFG and the right vmPFC distinguished victims from controls during exclusion. This effect was driven by aberrant connectivity in victims during inclusion rather than exclusion, indicating that victimization affects emotional responses and inclusion-related brain connectivity rather than exclusion-related brain activity or connectivity. Victims may respond differently to the social context itself. Enhanced negative emotions and connectivity deviations during social inclusion may depict altered social processing and may thus affect social interactions.

The effect of ostracism on prospective memory in problem solving.

Successfully generating plans, while seemingly straightforward, can be riddled with external and internal interferences. One important possible source of interference is ostracism, which has been consistently shown to induce negative psychological effects in various executive functions. Therefore, understanding the impact of unforeseen ostracism on planning is vital to a broad spectrum of the population, from university students, whose self-esteem partly derives from social acceptance, to healthcare professionals, whose performance oftentimes relies on peer feedback. An individual's ability to navigate through intended actions is an evaluation of their prospective memory (PM), which is traditionally divided into three consecutive phases: (1) planning, (2) recall, and (3) performance. This study primarily focused on the impacts of ostracism via Cyberball simulation on the first two phases of PM in the Tower of London (TOL), an assessment of executive functioning designed specifically to test planning ability during problem solving. Using Bayesian analysis, the study found substantial evidence of there being no difference in planning success between social exclusion and inclusion conditions. However, an individual's sex had significant effects on their planning success at baseline (i.e., inclusion condition). Surprisingly, there was no difference in performance between male participants and female participants when excluded, suggesting that ostracism may play an equalizing role. In addition, male participants both listed more moves at planning and recalled more moves, which led to no difference between sexes in terms of recall percentage. This study underscores a need to consider various factors such as sex and differing perceptions of ostracism when analyzing and addressing problem solving performance.

Decreased salivary alpha-amylase reactivity for excluded young women after a speech task.

Salivary alpha-amylase (sAA) has gained popularity as an easily collected biomarker for sympathetic nervous system activation, and research has shown increases in sAA after completing experimental stress tasks in certain groups. However, recent work suggests that salivary cortisol, another stress biomarker, is suppressed after a speech task among experimentally induced exclusion in young women. The present analysis investigated the sAA response in biologically female undergraduates (n=31) who completed a game of Cyberball and then a speech anticipation task. Results showed that women in the social exclusion experimental group had a greater decrease in sAA compared to young women in the inclusion group after the speech task. Results of this study provide support for stress response suppression in women who have experienced social exclusion. The present findings provide pilot evidence for future, larger studies to advance the tend-and-befriend theory.

Preexposure to one social threat alters responses to another social threat: Behavioral and electrophysiological evidence.

A recent Cyberball study has indicated that the experience of loss of control can affect how people process subsequent social exclusion. This "preexposure effect" supports the idea of a common cognitive system involved in the processing of different types of social threats. To test the validity of this assumption in the current study, we reversed the sequence of the preexposure setup. We measured the effects of social exclusion on the subsequent processing of loss of control utilizing event-related brain potentials (ERPs) and self-reports. In the control group (CG, n = 26), the transition to loss of control elicited significant increases in both the P3 amplitude and the self-reported negative mood. Replicating the results of the previous preexposure study, these effects were significantly reduced by the preexposure to an independent social threat (here: social exclusion). In contrast to previous findings, these effects were not modulated by the discontinuation (EG1disc, n = 25) or continuation (EG2cont, n = 24) of the preexposure threat. Given that the P3 effect is related to the violation of subjective expectations, these results support the notion that preexposure to a specific social threat has widespread effects on the individuals' expectancy of upcoming social participation and control.

When a Negative Experience Sticks With You: Does the Revised Outcome Debriefing Counteract the Consequences of Experimental Ostracism in Psychological Research?

For research purposes, it is generally accepted that experimental ostracism manipulations can lead to a reduction of participants' well-being. To eventually restore participants' well-being, researchers rely on post-experimental debriefings that discredit prior deception. However, evidence suggests that discredited beliefs can persevere. The present research investigates whether a potent debriefing procedure restores participants' well-being after an experimentally induced ostracism experience. In two studies, participants were either excluded or included in a Cyberball game, indicated their well-being, and were debriefed. In two additional conditions, participants were debriefed before indicating their well-being. Ostracism compared to inclusion led to decreased positive and increased negative mood. The debriefing did not counteract this effect (Studies 1 & 2). Unwanted aftereffects of the manipulation persevered for more than one day after the experimental session (Study 2). These findings question the effectiveness of debriefings and raise issues about research ethics.

Evidence of deviant parasympathetic response to social exclusion in women with borderline personality disorder.

Stressful social situations like social exclusion are particularly challenging for patients with borderline personality disorder (BPD) and often lead to dysfunctional reactive behaviour of aggression and withdrawal. The autonomous signature of these core symptoms of BPD remains poorly understood. The present study investigated the parasympathetic response to social exclusion in women with BPD (n = 62) and healthy controls (HC; n = 87). In a between-subjects design, participants experienced objective social exclusion or overinclusion in the Cyberball task, a virtual ball-tossing game. Need threat scores served as individual measures of perceived exclusion and the resulting frustration of cognitive-emotional needs. Five-minute measurements of high-frequency heart rate variability (HF-HRV) at three time points (before, during, after Cyberball) indicated parasympathetic tone and regulation. We observed a trend towards lowered baseline HF-HRV in BPD vs. HC in line with previous findings. Interestingly, the parasympathetic response of patients with BPD to objective and perceived social exclusion fundamentally differed from HC: higher exclusion was associated with increased parasympathetic activation in HC, while this autonomic response was reversed and blunted in BPD. Our findings suggest that during social stress, the parasympathetic nervous system fails to display an adaptive regulation in patients with BPD, but not HC. Understanding the autonomous signature of the stress response in BPD allows the formulation of clinically relevant and biologically plausible interventions to counteract parasympathetic dysregulation in this clinical group.

Neural correlates of social exclusion and overinclusion in patients with borderline personality disorder: an fMRI study.

BACKGROUND: Interpersonal difficulties of patients with borderline personality disorder (BPD) are closely related to rejection sensitivity. The aim of the present study was to gain further insight into the experience and cerebral processing of social interactions in patients with BPD by using fMRI during experimentally induced experiences of social exclusion, inclusion, and overinclusion. METHODS: The study involved 30 participants diagnosed with BPD (29 female and 1 male; age: M = 24.22, SD = 5.22) and 30 healthy controls (29 female and 1 male; age: M = 24.66, SD = 5.28) with no current or lifetime psychiatric diagnoses. In the fMRI session, all participants were asked to complete a Cyberball task that consisted of an alternating sequence of inclusion, exclusion, and overinclusion conditions. RESULTS: Compared to healthy controls, participants with BPD reported higher levels of inner tension and more unpleasant emotions across all experimental conditions. At the neural level, the participants with BPD showed lower recruitment of the left hippocampus in response to social exclusion (relative to the inclusion condition) than the healthy controls did. Lower recruitment of the left hippocampus in this contrast was associated with childhood maltreatment in patients with BPD. However, this difference was no longer significant when we added the covariate of hippocampal volume to the analysis. During social overinclusion (relative to the inclusion condition), we observed no significant differences in a group comparison of neural activation. CONCLUSIONS: The results of our study suggest that patients with BPD experience more discomfort than do healthy controls during social interactions. Compared to healthy participants, patients with BPD reported more inner tension and unpleasant emotions, irrespective of the extent to which others included them in social interactions. At a neural level, the participants with BPD showed a lower recruitment of the left hippocampus in response to social exclusion than the healthy controls did. The reduced activation of this neural structure could be related to a history of childhood maltreatment and smaller hippocampal volume in patients with BPD.

Unmet expectations: social inclusion and the interaction between social anxiety and ambiguous or positive feedback.

Introduction: This study explores the impact of preferential inclusion on fulfilling basic needs following ambiguous or positive social feedback, considering the moderating effect of social anxiety. Methods: Participants (N = 438) received either positive or ambiguous social feedback and engaged in a social participation or preferential social inclusion task. They completed measures of the fulfillment of their fundamental needs, social anxiety, and other personality traits. Results: The results indicate that preferential social inclusion (Uberball condition) enhances the fulfillment of fundamental needs compared to social participation (Cyberball inclusion condition). Furthermore, receiving positive social feedback considerably strengthens the negative relationship between social anxiety and fundamental need fulfillment when followed by ordinary social participation relative to preferential social inclusion presumably because these individuals react more strongly to unmet expectations of extreme social acceptance. Discussion: This research suggests that individuals with high social anxiety may not experience the usual benefits of social participation unless they experience extreme social inclusion.

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.

Understanding Capacities for Interpersonal Distress Tolerance in Individuals with Suicide Ideation.

INTRO: The relationship between suicide ideation (SI) and distress tolerance (DT) is characterized by inconclusive results. The current study aimed to test the association between tolerance for interpersonal distress and SI in light of the Interpersonal-Psychological Theory of Suicide. METHODS: 194 participants ranging in SI severity were recruited via Amazon Mechanical Turk and completed a cognitive distress task (Distress Tolerance Task) and an interpersonal distress task (CyberBall) to assess (1) the association between SI severity and persistence with the tasks, and (2) self-reported psychological distress associated with the tasks. RESULTS: A series of multilevel model analyses showed that increased SI predicted greater persistence with the interpersonal-distress task versus the cognitive distress task. In addition, higher SI predicted more distress during the interpersonal task. CONCLUSIONS: Individuals with higher SI levels demonstrated a greater capability to persist with the interpersonal distress, despite feeling psychologically worse. These findings further support the central role of interpersonal needs in SI by emphasizing the importance of operationalizing DT in a manner that is relevant to suicide desire.

SI is associated with persisting longer in interpersonally distressing situations.SI is also associated with higher levels of distress following social exclusion.In SI research the specific type of distress needs to be accurately operationalized.

Causal effects of appearance-related social exclusion on state body dissatisfaction among young Chinese adults.

OBJECTIVES: Numerous studies have linked experiences of appearance-related interpersonal rejection to body dissatisfaction (BD), though few experimental studies have been conducted. This study assessed causal effects of appearance-related social exclusion during an online Cyberball game on state BD as well as potential moderators of this association. METHODS: Young Chinese adults (60 women, 37 men; age 20.08 ± 1.32 years) were asked to provide an image of themselves that would be sent to other players prior to a visual perception study involving Cyberball, a virtual ball-tossing game that is used to elicit temporary social exclusion effects. Participants completed a trait Fear of Negative Appearance Evaluation (FNAE) measure before or after engaging in the Cyberball task in addition to post-task state measures of BD and positive mood facets. RESULTS: Participants randomly assigned to the social exclusion condition (i.e., receiving 2 of 30 possible throws) reported significantly higher post-Cyberball state BD and significant happiness/energy level/self-confidence deficits compared to peers in a social inclusion condition (i.e., receiving 12 out of 30 throws). A hierarchical regression analysis indicated social exclusion condition membership and trait FNAE elevations, but not their interaction, were significant predictors of higher state BD scores, independent of the impact of gender. CONCLUSIONS: Social exclusion experiences linked to physical appearance are a significant causal influence on increases in state BD and positive mood decrements among young Chinese adults.

Divergent emotional and autonomic responses to Cyberball in patients with opioid use disorder on opioid agonist treatment.

The perception of social exclusion among patients with opioid use disorder (OUD) could be affected by long-term opioid use. This study explores the emotional and cardiac autonomic responses to an experience of ostracism in a sample of participants with OUD on opioid agonist treatment (OAT). Twenty patients with OUD and twenty healthy controls (HC) performed a ball-tossing game (Cyberball) with two conditions: Inclusion and Ostracism. We measured self-reported ratings of perceived threat towards one's fundamental needs and respiratory sinus arrhythmia (RSA) immediately after the game and 10 min after Ostracism (Reflective stage). Following ostracism, participants with OUD self-reported blunted feelings of threat to the fundamental need to belong. RSA levels were significantly suppressed immediately after ostracism and during the Reflective stage in comparison with HC, indicating an autonomic alteration in response to threatening social situations. Finally, only among HC higher perceived threats towards fundamental needs predicted increases in RSA levels, suggesting an adaptive vagal regulation in response to a perceived threat. Conversely, among patients with OUD the subjective response to ostracism was not associated with the autonomic reaction. OAT may have a protective effect against negative feelings of ostracism. However patients with OUD on OAT present poor autonomic regulation in response to social threats, which could reflect their trait hypersensitivity to social rejection.
