替代性排斥对亲社会行为影响的综述

A Review of the Effects of Vicarious Ostracism on Prosocial Behavior

摘要: 替代性排斥是指个体目睹他人遭受排斥时产生的间接心理体验。关于其对观察者亲社会行为的影响，现有研究报告了促进与抑制两类结果。本文在厘清概念的基础上，从“共情–补偿”与“威胁–回避”两条路径梳理研究证据，并评述实验范式、样本构成、行为测量及因果推断的局限。现有结果涉及受排斥者定向补偿、一般助人意愿和社会回避等不同指标，不宜直接视为同一行为效应上的矛盾结论。在此基础上，本文提出有待检验的社会信息加工解释：社交焦虑通过自我聚焦注意影响对他人需求信息的持续注意与整合，并提高预期负面评价在决策中的权重，从而限制共情向实际帮助的转化。未来研究应结合注意过程测量、真实成本助人任务与日常情境追踪，以检验该解释的适用性。

Abstract: Vicarious ostracism refers to the indirect psychological experience of witnessing others being ostracized. Research has reported both facilitative and inhibitory effects on observers’ prosocial responses. This review organizes the evidence around empathy-compensation and threat-avoidance pathways and critically examines limitations in experimental paradigms, sampling, outcome measurement, and causal inference. Compensation directed toward an excluded target, general helping intentions, and social avoidance are distinct outcomes; differences between them should not be treated as contradictory effects on an identical behavior. The review then proposes a social information-processing account that remains to be tested: social anxiety shifts attention toward the self, constrains sustained processing of others’ needs, and increases the decision weight assigned to anticipated negative evaluation, thereby limiting the translation of empathy into helping. Future research should combine measures of attentional processes, helping tasks with real costs, and assessments in everyday contexts to test the conditions under which this account applies.
