Distinct neural dynamics of the observed ostracism effect in decision-making under risk and ambiguity.

Observational ostracism, as a form of social exclusion, can significantly affect human behavior. However, the effects of observed ostracism on risky and ambiguous decision-making and the underlying neural mechanisms remain unclear. This event-related potential study investigated these issues by involving participants in a wheel-of- fortune task, considering observed ostracism and inclusion contexts. The results showed that the cue-P3 component was more enhanced during the choice phase for risky decisions than for ambiguous decisions in the observed inclusion contexts but not in the observed ostracism contexts. During the outcome evaluation phase, feedback-related negativity amplitudes following both risky and ambiguous decisions were higher in the no-gain condition than in the gain condition in the observed inclusion context. In contrast, this effect was only observed following risky decisions in the observed ostracism context. The feedback-P3 component did not exhibit an observed ostracism effect in risky and ambiguous decision-making tasks. Risk levels further modulated the cue-P3 and feedback-related negativity components, while ambiguity levels further modulated the feedback-P3 components. These findings demonstrate a neural dissociation between risk and ambiguity decision-making during observed ostracism that unfolds from the choice phase to the outcome evaluation phase.

Resting-state neural correlates of individual differences in ignored experience and its deleterious effect.

Uncovering the neural mechanisms of ostracism experience (including its subclasses of excluded and ignored experiences) is important. However, the resting-state functional brain substrates responsible for individual differences in ostracism experience and its negative effects remain largely undefined. This study explored these issues in a sample of 198 Chinese college students by assessing the amplitude of low-frequency fluctuations and functional connectivity. The findings indicated a positive correlation between ignored experience and the amplitude of low-frequency fluctuations in the right superior frontal gyrus and the functional connectivity between the right superior frontal gyrus and left cerebellum posterior lobe. Additionally, a negative correlation was found between ignored experience and the functional connectivity between the right superior frontal gyrus and the bilateral insula as well as the bilateral inferior parietal lobule. Moreover, the mediation analysis demonstrated that the effects of the functional connectivities of right superior frontal gyrus-left cerebellum posterior lobe and right superior frontal gyrus-right inferior parietal lobule on revenge intention were mediated by ignored experience. Our study offers novel insights into the neural correlates of both individual variations in ignored experience and its typical deleterious effect. These results could deepen our understanding of individual differences in negative experiences and inspire the development of targeted interventions for social stress from the perspective of the brain.

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.

Workplace ostracism in healthcare: Association with job satisfaction, stress, and perceived health.

AIMS: To examine (1) the association between healthcare workers' workplace ostracism and job satisfaction, stress and perceived health, and (2) whether this relationship is mediated by loneliness and self-esteem. DESIGN: A cross-sectional study. METHODS: Healthcare (N = 569) managers and employees (nurses, practical nurses, doctors and social workers) in Finland responded to a semi-structured survey in January 2021 and evaluated their experiences of workplace ostracism, job satisfaction, stress, perceived health, loneliness and self-esteem during the last year. To examine the association of these variables, linear regression and mediator model tests were performed. RESULTS: Workplace ostracism had a clear direct association with job satisfaction, stress and perceived health. Loneliness fully mediated the relationship between workplace ostracism, stress and perceived health, and partly mediated the association between workplace ostracism and job satisfaction. Self-esteem partly mediated the association between workplace ostracism, stress, job satisfaction and perceived health. CONCLUSION: The experience of workplace ostracism in organizations is a significant factor in job satisfaction, stress and perceived health. Healthcare organizations could strengthen job satisfaction and increase workers' well-being by strengthening social relationships in the organization and, via that, reducing turnover intention. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE: This study gives understanding and information to the healthcare profession on how workplace ostracism affects work well-being and workplace relationships. Workplace ostracism decreases interaction, which can also endanger patient care if information is not openly exchanged. IMPACT: This study indicated that workplace ostracism weakened job satisfaction more than loneliness. More commonality and consideration for others at work are needed because these factors may help increase work well-being and decrease exits from working life. Further research is needed on why workplace ostracism occurs in healthcare workplaces. REPORTING METHOD: STROBE. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

It will (never) stop hurting: Do repeated or chronic experiences of exclusion lead to hyper- or hyposensitive psychological responses?

Unlike one-time lab manipulations of exclusion, in real life, many people experience exclusion, from others and from groups, over extended periods, raising the question of whether individuals could, over time, develop hypo- or hypersensitive responses to chronic exclusion. In Study 1, we subjected participants to repeated experiences of inclusion or exclusion (three Cyberball games, time lag of three days, N = 194; 659 observations). We find that repeatedly excluded individuals become hypersensitive to inclusion, but not to exclusion. Study 2 (N = 183) tested whether individuals with chronic experiences of real-world exclusion show hypo- or hypersensitive responses to a novel episode of exclusion. In line with Study 1, exclusion hurt to the same extent regardless of baseline levels of chronic exclusion in daily life. However, chronically excluded individuals show more psychological distress in general. We discuss theoretical and practical implications for dealing with chronically excluded individuals and groups.

Profiles of Loneliness and Ostracism During Adolescence: Consequences, Antecedents, and Protective Factors.

This longitudinal study (N = 1078, 46% boys; 54% girls) examined profiles of loneliness and ostracism during adolescence and their consequences and antecedents. Longitudinal latent profiles analyses identified four distinct profiles: (1) High emotional loneliness (25%), High and increasing social loneliness (15%), High peer exclusion and high social impact (9%) and No peer problems (51%). Subsequent internalizing problems were typical for the High and increasing social loneliness profile and externalizing problems for the High emotional loneliness and High peer exclusion and high social impact profiles. Furthermore, effortful control, prosocial skills, and relationship quality with parents and teachers were highest in the No peer problems profile, whereas the High and increasing social loneliness profile had the lowest self-esteem and was characterized by low surgency/extraversion, high affiliativeness, and high negative affectivity.

Work ethics and its relationship with workplace ostracism and counterproductive work behaviours among nurses: a structural equation model.

BACKGROUND: The organization's work ethics is the cornerstone to promoting positive nurses' behaviours and overcoming counterproductive ones. PURPOSE: The current study aims to explore the relationship between work ethics (WEs) and counterproductive work behaviours (CWB) among nurses and testify to the mediating role of workplace ostracism (WO) in this relationship. METHODS: A descriptive correlational study was conducted in an Egyptian hospital. A convenient sample of staff nurses (N = 369) who agreed to participate in the study answered work ethics, counterproductive work behaviours, and workplace ostracism questionnaires, which were proven to be valid and reliable study measures. Descriptive and inferential statistics were applied, and relationships were presented using structural equation modelling. ETHICAL CONSIDERATIONS: Ethics Committee approval, written informed consent, data privacy and confidentiality, and participants' rights to voluntary participation and withdrawal were maintained. RESULTS: The majority of nurses (78.5%) perceived a high level of work ethics while majority of nurses reporting low levels of counterproductive work behaviours and workplace ostracism (82.25%, 75.75%), respectively. In addition to the negative correlations, the findings revealed that WEs have a significant negative influence on each of CWB (ß - 0.482, p < 0.005) and WO (ß - 0.044, p < 0.005). The regression analysis showed that WEs can negatively predict about 15% of the variance in each of CWB and WO. On the other hand, WO has a positive effect on CWB (ß 0.035, p < 0.021) and mediates the relationship between WEs and CWB. DISCUSSION: Ostracism negatively affects the attitudes of nurses, which in turn results in negative behavioural outcomes (i.e., deviant behaviour). CONCLUSION: It is imperative for the hospital and nurse managers to establish a work environment that fosters support and cultivate work ethics and ethical work climate with the aim of managing negative work behaviours, enhancing nurses' retention and satisfaction, and eventually improving the quality of patient care.

Aggressive intentions after social exclusion and their association with loneliness.

Both social exclusion and loneliness are aversive experiences that can lead to hostile behavioral reactions, including aggressive behavior. This study aimed to assess whether a social exclusion scenario in the subject's imagination elicits aggressive reactions towards an excluding person as measured with the hot sauce paradigm. Furthermore, we studied the effect of loneliness on such reactions. In total, 251 subjects (67.7% female; mean age 27.3 ± 9.3 years) participated in this study which was based on an online survey. After trait loneliness was assessed with the UCLA Loneliness scale at baseline, two imaginary scenarios were presented in randomized order, i.e., an exclusion condition (with one of two working colleagues excluding the participant from a social activity) and an inclusion condition (without exclusion). Following each scenario, participants had the task to allocate the amount of hot sauce to each colleague that they find appropriate. Participants distributed significantly more hot sauce to the excluder than to the includers. The amount of hot sauce was significantly correlated with loneliness for all includer interactions (i.e., after the inclusion as well as the exclusion scenario), but not for the interaction with the excluder. Our results support the hypothesis that social exclusion elicits aggressive behavior. Interestingly, the experience of loneliness seems to be associated with an increase in aggressive behavioral tendencies or a lack of their inhibition. The cognitive and/or emotional processes underlying the interplay between social exclusion, loneliness and aggression should be a focus of future research.

Do preschoolers track and evaluate social includers and excluders?

Social exclusion is harmful and leads to negative consequences across the lifespan. Based on studies primarily with adults, psychologists have characterized a highly sensitive "ostracism detection system" that acts quickly and automatically to detect exclusion and mitigate its effects. However, research with children has not fully explored whether a system with similar characteristics is operational in early childhood, and prior work probing children's responses to exclusion has produced mixed findings. We investigated 4- to 6-year-old children's abilities to negatively evaluate those who have excluded them as well as to use these experiences for prosocial gossip. Children engaged one pair of play partners in an inclusive game and engaged another pair in an exclusive game. Nearly one third (n = 28 of 96) did not accurately recall who had excluded them. Yet those who did recall their game experiences evaluated excluders more negatively than includers, and they were less likely to recommend excluders as play partners to others. These findings indicate that not all children sensitively track their excluders' identities-but those who do so will evaluate excluders negatively. More work is needed to understand developments in how and when children recognize their own exclusion and whether the underlying processes should be viewed as homologous to adults' ostracism detection system.

Reconsidering the role of interpersonal stress in eating pathology: Sensitivity to rejection might be more important than actual experiences of peer stress.

Rejection sensitivity (i.e., the tendency to anxiously expect, readily perceive, and overreact to real or perceived rejection) is theorized to play a role in the onset and maintenance of disordered eating. Although rejection sensitivity has repeatedly been associated with eating pathology in clinical and community samples, the pathways through which this psychological trait influences eating pathology have been not fully established. The current study investigated peer-related stress, which can be influenced by rejection sensitivity and is associated with eating pathology, as a mechanism linking these constructs. In two samples of women - 189 first-year undergraduate students and 77 community women with binge eating - we examined whether rejection sensitivity was indirectly associated with binge eating and weight/shape concerns via ostracism and peer victimization, both cross-sectionally and longitudinally. Our hypotheses were not supported: there were no indirect associations between rejection sensitivity and eating pathology via interpersonal stress in either sample. However, we did find that rejection sensitivity was directly associated with weight/shape concerns in both samples and with binge eating in the clinical sample in cross-sectional (but not longitudinal) analyses. Our findings suggest that the association between rejection sensitivity and disordered eating is not dependent on actual experiences of interpersonal stress. That is, simply anticipating or perceiving rejection may be sufficient to play a role in eating pathology. As such, interventions targeting rejection sensitivity may be helpful in the treatment of eating pathology.

Intensity, intent, and ambiguity: Appraisals of workplace ostracism and coping responses.

Using both correlational and experimental designs across four studies (N = 1251 working individuals), the current project aimed to contribute to the understanding of workplace ostracism by studying two research questions. First, we tested whether the subjective experience of targets reflects the current theorizing of ostracism. Second, drawing from the transactional theory of stress and coping, we investigated whether this subjective experience impacts targets' coping responses. Findings based on exploratory and confirmatory factor analyses supported the current theorizing of workplace ostracism such that perceived intensity, intent, and ambiguity were reflected in how targets appraised being ostracized at work. The appraisals were also related to coping responses. Perceived intensity predicted more approach-oriented (e.g., confrontation) and less avoidance-oriented coping responses (e.g., minimization). While attributions of intent also predicted some coping responses (e.g., instrumental support seeking), the explanatory power of perceived ambiguity was lower than the other two appraisals. Although these researcher-defined dimensions may be reflective of targets' experience, we propose that predictions made based on these dimensions need further refinement. The theoretical and practical significance of these findings are discussed in relation to how workplace ostracism is typically studied in the literature.

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.

The mediating role of social ostracism in the effect of social media addiction on loneliness in adolescents.

OBJECTIVE: This study aimed to determine the mediating role of social ostracism in the effect of social media addiction on loneliness in adolescents. METHODS: This descriptive and cross-sectional study was conducted with 1225 adolescent students attending high school in a province in Eastern Turkey between 30 May 2023 and 01 August 2023. The study data were collected using the "Personal Information Form", "Bergen Social Media Addiction Scale", "UCLA Loneliness Scale-Short Form" and "Ostracism Experience Scale for Adolescents". The analysis of the study data was performed by using SPSS 22.0, AMOS V 24.0, and G*Power 3.1 Statistical package software. RESULTS: It was determined that the model created in line with the determining the mediating role of social ostracism in the effect of social media addiction on loneliness in adolescents was compatible and the model fit indices were within the desired limits x2/df = 4.481, RMSEA = 0.05, CFI = 0.96, GFI = 0.96, AGFI = 0.94, IFI = 0.96. Social media addiction has been found to affect loneliness and social ostracism (p < 0.05). It was found that social ostracism affected the level of loneliness (p < 0.05). It was determined that social ostracism had a mediating role in the effect of social media addiction on loneliness (p < 0.05). CONCLUSION: As the level of social media addiction increases, the level of loneliness and social ostracism increases. As the level of social ostracism increases, the level of loneliness increases. Longitudinal studies on the factors affecting loneliness are recommended. PRACTICE IMPLICATIONS: In order to reduce the loneliness and social ostracism levels of adolescents, their access to social media should be controlled. Programs to reduce social ostracism should be designed.

Social stress, performance after-effects and extra-role behaviour.

The article is concerned with the after-effects of social stress on work performance. In a lab-based experiment, seventy participants were assigned to either a stress condition or a no-stress condition. In the stress condition, participants received fake negative performance feedback and they were ostracised by two confederates of the experimenter. Participants carried out the following tasks: attention and divergent creativity. The effects of social stress were examined at three levels: performance after-effects on unscheduled probe tasks, extra-role behaviour and subjective operator state. The manipulation check confirmed that participants experienced social stress. The results showed after-effects of social stress for some forms of extra-role behaviour (i.e. spontaneous reactions) and for the accuracy component of attention. Furthermore, social stress was found to increase negative affect and to reduce self-esteem. The findings point to the importance of assessing different types of after-effects rather than limiting the methodological approach to instant effects on performance.Practitioner summary: The study aimed to examine the multiple effects of social stress. Social stress resulted in increased negative affect and lower self-esteem. Furthermore, social stress was found to reduce the propensity of humans to show extra-role behaviour (i.e. providing spontaneous help to others).

Post COVID-19 workplace ostracism and counterproductive behaviors: Moral leadership.

BACKGROUND: The wide proliferation of Covid-19 has impacted billions of people all over the world. This catastrophic pandemic outbreak and ostracism at work have posed challenges for all healthcare professionals, especially for nurses, and have led to a significant increase in the workload, several physical and mental problems, and a change in behavior that is more negative and counterproductive. Therefore, leadership behaviors that are moral in nature serve as a trigger and lessen the adverse workplace effects on nurses' conduct. AIM: this research is directed to explore the impact of post-COVID-19 workplace ostracism on nurses' counterproductive behavior and examine the role of moral leadership as a mediating factor in post-COVID-19 workplace ostracism and nurses' counterproductive behavior. ETHICAL CONSIDERATION: Ethical review and approval Was received from Ethical Committee at the Faculty of Nursing, Alexandria University, Egypt. METHODS: A cross-sectional and correlation study was implemented in all units of medical, surgical, critical and intensive care units by using three tools; moral leadership questionnaire, Workplace Ostracism Instrument (WOS), and Counterproductive Work Behaviors Questionnaire (CWBs). A convenient sample of 340 from 699 bedside nurses was granted. RESULTS: This study revealed that nurses' perceived moderate mean percent (55.49 ± 3.46) of overall workplace ostracism and counterproductive behavior (74.69 ± 6.15). However, they perceived a low mean percentage of moral leadership. There was a significant positive correlation between workplace ostracism and counterproductive behavior. Otherwise, a significant negative correlation was found between moral leadership, workplace ostracism and counterproductive behavior. Also, this study proved the mediating effect of moral leadership in decreasing workplace ostracism by 79.3% and counterproductive behavior by 36.7%. CONCLUSION: Hospital administrators need to be aware of the significance of moral leadership and apply integrity in the clinical setting to reduce the drawback of isolation on nurses' conduct and increase value for the organization as a whole and nurses in particular.

Unethical pro-supervisor behavior and employees' family satisfaction: The roles of workplace ostracism and work-home segmentation preference.

The present study proposes a moderated mediation model that examines how and when unethical pro-supervisor behavior is related to employees' family satisfaction. The two-wave study design consisted of 207 full-time employees in China. The study results indicate that unethical pro-supervisor behavior is negatively related to family satisfaction, and that workplace ostracism mediates the influence of unethical pro-supervisor behavior on family satisfaction. In addition, the relationship between workplace ostracism and family satisfaction as well as the indirect influence of unethical pro-supervisor behavior on family satisfaction through workplace ostracism, are moderated by employees' work-home segmentation preference. The study findings not only enrich the literature on unethical pro-supervisor behavior, but also have important practical implications for organizational managers.

What Happens to Those Who Exit Jehovah's Witnesses: An Investigation of the Impact of Shunning.

Shunning and ostracism have severe impacts on individuals' psychological and social well-being. Members of Jehovah's Witnesses are subject to shunning when they do not comply with the stated doctrine or belief system. To investigate the effects of shunning, interviews with 10 former Jehovah's Witnesses, ranging in age from 20 to 44 years old, were conducted; six male, six White, one Native American, one Black, and two Latinx. Transcripts were analyzed with interpretative phenomenological analysis for narrative themes pertaining to their life after exclusion from their former faith using the context of Jehovah's Witnesses culture. Results suggest shunning has a long-term, detrimental effect on mental health, job possibilities, and life satisfaction. Problems are amplified in female former members due to heavy themes of sexism and patriarchal narratives pervasive in Jehovah's Witnesses culture. Feelings of loneliness, loss of control, and worthlessness are also common after leaving. The culture of informing on other members inside the Jehovah's Witnesses also leads to a continued sense of distrust and suspicion long after leaving.

DRD4 polymorphism associated with greater positive affect in response to negative and neutral social stimuli.

Despite the robustness of DRD4 polymorphism associations with brain-based behavioral characteristics in candidate gene research, investigations have minimally explored associations between these polymorphisms and emotional responses. In particular, the prevalent single nucleotide polymorphism (SNP) -521C/T (rs1800955) in the promoter region of DRD4 remains unexplored relative to emotions. Here, two independent samples were evaluated using different emotion elicitation tasks involving social stimuli: Study 1 (N = 120) evoked positive and negative emotional responses to validated film clips; Study 2 (N = 122) utilized Cyberball to simulate social rejection and acceptance. Across studies, C/C individuals self-reported higher mean positive affect scores using Likert scales versus T carrier individuals, selectively when presented with neutral or negative (but not positive) social stimuli. The consistent findings across these two studies supports a functional consequence of this DRD4 SNP on emotion processing during changing social contexts. Continued investigation will help clarify if a C/C genotype enhances positive emotions under negative circumstances, or if the presence of the T allele reduces positive emotions, and how rs1800955 behavioral associations might generalize across different demographics. Future studies could also reveal if this SNP interacts with other changing environmental conditions to affect emotional responses, such as social limitations during the COVID-19 pandemic.

Does social defeat cause negative symptoms? A prospective study in a multi-national community sample.

Psychological models of the consequences of ostracism (i.e. being socially excluded and ignored) and negative symptoms in schizophrenia suggest that repeatedly experiencing ostracism can lead to elevated levels of amotivation, anhedonia, and asociality (i.e. negative symptoms). We tested this assumption in a prospective study, following up a large multi-national community sample from Germany, Indonesia, and the United States (N = 962) every four months over one year. At each of the four assessment points (T0 - T3), participants rated their recent ostracism experiences and negative symptoms. Using cross-lagged panel analyses we found a) that negative symptoms and experiences of ostracism were significantly associated in each of the four assessment points, b) that ostracism predicted negative symptoms over time (T2 to T3), and c) that negative symptoms increased ostracism (T0 to T1). The results are in line with the social defeat model of negative symptoms and suggest a bi-directional longitudinal relationship between ostracism and negative symptoms. Moving forward, it will therefore be important to gain an understanding of potential moderators involved in the mechanism.

The mechanisms underlying the negative effect of depression on life satisfaction among the elderly: the roles of ostracism and economic income.

OBJECTIVES: Depression is prevalent among older persons, which seriously threatens their life satisfaction. This study aimed to explore the internal mechanisms by which depression influences life satisfaction among the elderly, as well as the mediating and moderating effects of ostracism and economic income, respectively, in a sample of rural older adults across China. DESIGN: This was a cross-sectional survey conducted as part of the project "Thousands of People and Hundreds of Villages (2019)." SETTING: Participants were rural older adults from 31 provincial-level administrative units across China. PARTICIPANTS: The sample composed of 1,754 participants aged 60 years and over. MEASUREMENTS: Depression was assessed with the depression subscale of the Depression Anxiety Stress Scales, life satisfaction with the Satisfaction with Life Scale, ostracism with the Ostracism Experience Scale (OES), and economic income and other control variables with related demographic scales. Moderation and mediation analyses were performed using the regression-based approach as conducted by Hayes (). RESULTS: Depression negatively predicted life satisfaction among the elderly. Ostracism played a partially mediating role between depression and life satisfaction. Economic income moderated the effect of depression and ostracism on life satisfaction: High economic income weakened the negative effect of depression on life satisfaction and enhanced the negative effect of ostracism on life satisfaction. CONCLUSION: Improving depressed elderly people's interpersonal relationships and financial support could improve their life satisfaction.
