Cooperation after social exclusion: To reconnect or to harm?

Abstract

Predicting a person's reaction after experiencing exclusion is an important question, which is accompanied by paradoxical answers. An excluded person may tend to harm others (antisocial reaction hypothesis), treat them with increased ingratiation (prosocial reaction hypothesis), or withdraw from further social contacts. The aim of this study was to test the hypotheses about the prosocial and antisocial responses in the social dilemma context, specifically, to examine whether social exclusion will result in reduced or increased cooperation in the Trust Game. The sample included 175 participants (females = 142), first‐ and second‐year psychology students. There was a between‐subject design 3 exclusion (exclusion vs. inclusion vs. neutral) × 2 history (known vs. unknown partner), with Social value orientation being treated as a covariate. Social exclusion was manipulated using the get‐acquainted paradigm, and the Trust Game was used to measure the willingness to cooperate. The level of social value orientation was measured using the Social Value Orientations (SVO) Slider Measure. Despite the successful manipulation of social exclusion, the results do not support studies showing that exclusion influences cooperation in a mixed‐motive situation. Only the main effects of the history were observed (p = .012, η2 = .04.), and social value orientation was a significant predictor of the level of cooperation (p ≤ .001, η2 = .08.). The conclusion is that the experience of social exclusion made participants no less able to analyze social cues and willing to cooperate in the Trust Game.
