Abstract This paper presents a meta-analysis of 79 cases (N = 21,857) testing the effectiveness of mediated intergroup contact on prejudice. Positive mediated contact decreased (r = −.23; 95% CI, −.29 to −.17), whereas negative mediated contact increased prejudicial attitudes (r = .31; 95% CI, .24 to .38) and intergroup anxiety and empathy were both significant mediators of these relationships. Furthermore, the data revealed no significant differences between parasocial and vicarious effects, positive and negative mediated-contact effects, or the effects of the duration of mediated-contact stimulus exposure on prejudice. However, the data did reveal experiments to have stronger effects than survey research. These and other results are discussed along with implications, limitations, and future research directions.

中介接触与偏见的元分析

摘要 本文对 79 例 (N = 21,857) 进行了荟萃分析，以测试介导的群体间接触对偏见的有效性。积极介导的接触减少（r = -.23；95% CI，-.29 至 -.17），而消极介导的接触增加了偏见态度（r = .31；95% CI，0.24 至 .38）和群际焦虑和同理心都是这些关系的重要中介。此外，数据显示准社会和替代效应、积极和消极的中介接触效应或中介接触刺激暴露持续时间对偏见的影响之间没有显着差异。然而，数据确实显示实验比调查研究具有更强的效果。讨论了这些和其他结果以及影响、局限性和未来的研究方向。
