Abstract:

Social exclusion has two dimensions. One is the target of the exclusion (i.e., the victim) and the other is the source of exclusion (i.e., the rejecter). However, existing paradigms focusing on rejecters have exhibited a limitation in their ability to consistently elicit exclusionary behavior. To address this gap, the present study integrated social exclusion within the framework of the Public Good Game (PGG) and devised a novel paradigm for rejecters. This new paradigm demonstrated a significantly higher success rate in inducing exclusionary behavior. Furthermore, we used two experiments to test it. The result of Experiment 1 showed that participants of the experiment group had a significantly higher rate to do the exclusion behavior than the control group. To simulate real-life social exclusion contexts, Experiment 2 introduced an “anonymous” factor. The results revealed that participants of the experiment group exhibited a significantly higher rate of engaging in social exclusion behavior under the anonymous condition compared to the public condition. The newly developed paradigm in this study proves to be highly effective in eliciting social exclusion behavior, providing a fresh approach to examining social exclusion from the perspective of the rejecter.

Key words: social exclusion, motivation of social exclusion, Public Goods Game, rejecter

摘要：

已有的排斥者研究范式通常存在诱发效率不高的缺点。本研究结合公共物品博弈框架(PGG)，开发了一个能够高效地引发排斥行为的实验范式，并用两个实验对该范式的有效性进行了检验。结果发现，被试对损害团体利益的成员均表现出高度的排斥行为：实验1中实验组被试的排斥诱发率显著高于对照组；实验2增加匿名/公开情境，发现实验组中，匿名条件下被试的排斥行为显著多于公开条件。结果表明，该范式能够稳定有效地诱发排斥行为，是排斥者研究的新方法。
