研究一通过相关法（N = 267），采用自编成长观问卷、简式自我控制量表以及青少年排斥经历量表，考察了成长观在社会排斥与自我调节能力关系中的调节作用。研究发现，社会排斥可以负向预测个体的特质性自我控制水平，成长观可以正向预测个体的特质性自我控制水平，成长观在社会排斥与自我调节能力关系中的调节效应显著。研究二通过实验法(N = 55)进一步做出因果推论。选取坚持性作为指标测量个体的自我调节/自我控制水平，首先通过基于虚拟现实技术的网络聊天任务启动被试的排斥感/接纳感，之后通过文章阅读启动被试的成长观/有害观信念，最后被试完成举哑铃任务。结果发现，社会排斥的主效应不显著，信念启动的主效应不显著，交互作用显著。对于排斥组来说，接受成长观信念启动的个体在哑铃任务上的坚持性显著优于有害观信念启动的表现；对于社会接纳组来说，不同信念启动组个体在哑铃任务上的坚持性不存在显著差异。该结果排除了情绪的中介作用、有害观信念启动对个体排斥感的诱发以及成长观信念的溢出效应等可能解释。本研究支持了社会排斥的隐性契约理论，并揭示了认知策略（成长观）在应对社会排斥引发的负面效应中所具有的重要作用。未来研究可通过不同的自我调节测量范式验证该结果，并探讨个体原先具有的成长观信念能否应对排斥后的自我调节失败。

The present study investigated whether holding growth mindset can buffer the negative effect of ostracism on self-regulation. Two studies provided converging evidence. Study 1 carried out correlational design (N = 267) and found that social exclusion together with weak growth mindset predicted impaired trait self-control, while growth mindset moderated the relationship between chronic ostracism experience and trait self-control, thus provided preliminary evidence that growth mindset buffer the negative effect of ostracism on dispositional self-regulation. Study 2 (N = 55) used experimental design to further drew the casual inference. We found that ostracized participants (manipulated by VR-version O-Cam paradigm) who were primed with the belief that ostracism was detrimental to personal growth and development showed declined persistence than their included counterparts in a tired and distressing handgrip task. In contrast, participants who were primed with the beliefs that ostracism could aid their growth and development were resistant to the self-regulatory failure followed by ostracism. Alternative explanation such as mood mediation, the effect of harm mindset on perceived ostracism, and the spillover effect of growth mindset on self-regulation have been ruled out. The present studies supported the implicit bargain theory, and shed light on the cognitive strategy naming growth mindset for post-ostracism coping. Future research can use different self-regulation paradigms to provide converging evidence, and can also investigate how the preexisting growth mindset works to cope with self-regulatory failure following ostracism.
