Mental contrasting promotes effective self-regulation for the benefits of groups

Self-regulation is essential for maintaining harmonious social connections and sustaining groups, yet little research has examined how individuals regulate their actions for the benefits of groups and which self-regulatory strategies promote effective self-regulation (active engagement and disengagement) in group contexts. In three experiments, focusing on identity groups (family and friends in Study 1) and two distinct functional groups (workplace teams in Study 2; sports teams in Study 3), we investigated whether mental contrasting of a desired future with the obstacle of reality, compared to indulging in the desired future, facilitates expectancy-dependent contributions for the benefits of groups. We assessed participants' expectancies of successfully contributing to their groups and varied the mode of thought (mental contrasting vs. indulging). Contributions to groups were measured 1 week (Studies 1 and 2) and 3 weeks later (Study 3). Results showed that mental contrasting guided people to align their actions with expectancy levels; the higher their expectancy, the more people contributed to their groups. In contrast, indulging resulted in insensitivity to expectancy levels. Our findings suggest the potential applicability of the mental contrasting strategy for promoting effective self-regulation in various group settings and provide insights into designing interventions to enhance individuals' engagement in groups.
