The effect of uniform virtual appearance on conformity intention: Social identity model of deindividuation effects and optimal distinctiveness theory

摘要

This study integrates social identity model of deindividuation effects (SIDE) and optimal distinctiveness theory (ODT) in investigating the effect of uniform virtual appearance on individuals’ willingness to conform to a majority opinion in computer-mediated groups. SIDE posits that sharing the same visual cue can promote group identification process and eventually induce stronger conformity. Meanwhile, ODT indicates that too much visual similarity rather concerns individuals about their deprived uniqueness, so they would be reluctant to conform to a majority opinion as a way to restore their uniqueness. This study concurs with previous research based on SIDE by showing that group identification induced by uniform appearance increases conformity intention. It also showed that perceived deindividuation, another variable that is induced by a high level of visual similarity relative to others, decreases conformity intention. As a result, the current study shows that the effect of virtual uniform appearance on conformity intention is inconsistently mediated by group identification and perceived deindividuation.
