Ostracism -being excluded and ignored -is painful and threatens needs for belonging, self-esteem, control and meaningful existence. Many studies have shown that immediate responses to ostracism tend to be resistant to moderation. Once ostracized individuals are able to reflect on the experience, however, personality and situational factors moderate recovery speed and behavioural responses. Because attachment orientation is grounded in perceptions of belonging, we hypothesized that attachment orientation would moderate both immediate and delayed reactions to laboratory-induced ostracism. Participants from individualistic or collectivistic cultures were either included or ostracized in a game of Cyberball, a virtual ball-toss game. In both cultures, we found that compared to more securely attached individuals, more avoidant participants were less distressed by ostracism, but more distressed by inclusion. It is suggested that over and beyond differences in culture, individuals who avoid meaningful attachment may be less affected by ostracism.

Although numerous studies have shown that prosocial behavior impacts performance within organizations, the mechanisms that encourage or discourage these effects have rarely been explored. Two studies were conducted to shed light on the role of psychological beliefs on prosocial dynamics in predicting organizational performance. In Study 1, employees' beliefs in their inner job-related resources (Occupational Efficacy-OE) were examined as a predictor of OCB. It was posited that OE, which is an inner resource, should positively predict OCB. Study 2 examined whether Collective Efficacy (CE), which is an external resource over which employees have less control, would moderate the OCB-performance prediction. Overall, performance and three core dimensions of performance (quality, creativity and efficiency) were assessed to better capture the specific influence of OCB effects on performance. In Study 1, employees completed inventories measuring their OE, OCB and performance. In Study 2, employees completed inventories measuring their CE and OCB. In addition, their managers completed inventories measuring the CE of their employees' teams and their employees' performance. The results of Study 1 revealed that OE emerged as an antecedent of OCB in predicting performance. In Study 2, OCB positively predicted employee performance above and beyond and the effects of their managers' tenure in position, and CEs. In addition, both employees' and managers' CEs moderated the effects of OCB on performance: the performance effects of OCB increased as employees' and managers' CE increased, and specifically performance efficiency and performance creativity. These findings contribute to a better theoretical and practical understanding of the core factors that affect the organizational dynamics of prosocial behaviors that can lead to higher performance, and the ways in which OCB positively predicts performance in organizational settings.

Ostracism is known to cause psychological distress. Studies have indicated that immediate distress is resistant to individual differences and situational factors, but delayed reactions are more sensitive to moderation. Because attachment orientation is inextricably tied to rejection and inclusion, we hypothesized that attachment orientation would moderate both immediate and delayed ostracism effects and that recalling an attachment event compatible with a person's attachment internal working model would moderate the distress of a laboratory ostracism experience. In two experiments, 158 individualistic (secular Jewish) and 190 collectivistic (ultra-Orthodox Jewish) participants played Cyberball with two other ostensible in-group players. Distress was measured immediately after the game and 30 minutes later. The results show that less anxious and more avoidant individualistic but not collectivistic participants were less distressed by ostracism. After the delay, recall of an attachment event compatible with the participants' internal working model eliminated distress in both individualistic and collectivistic ostracized participants as measured on the needs satisfaction scale. Among individualistic participants, avoidants, who are known to avoid meaningful attachments, were less distressed by ostracism; anxious participants, who seek proximity, were more distressed. Recalling a compatible attachment event may be a mechanism that reduces individuals' perceptions of threats to their fundamental needs.
