Media and the contact hypothesis. An experimental study on the impact of parasocial contact.

Does parasocial contact impact on inter-group bias? Widening the scope of Contact Theory, this study aims at experimentally examine the impact of parasocial out-group presentation on decisions in a two-person prisoner's dilemma game and social cognitive constructions of the social event. Within a minimal group experiment, 80 university students were randomly assigned to anonymous or video-wise personalization conditions. Participants rather took personal advantage of expected contributions to a commonly shared dilemma situation in anonymous settings than if a member of the out-group was personalized (p < .05). As perceptions of group boundaries, out-group homogeneity, and similarity did not systematically differ across the conditions, implications are discussed.

准社会接触（parasocial contact）是否会对群际偏见（inter-group bias）产生影响？本研究旨在拓展群际接触理论（Contact Theory）的研究范畴，通过实验探究准社会外群体呈现对双人囚徒困境博弈（two-person prisoner's dilemma game）中的决策行为，以及该社会事件的社会认知建构的影响。本研究采用最小群体实验（minimal group experiment）范式，招募80名大学生被试并将其随机分配至匿名条件与视频个性化条件。实验结果表明，相较于外群体成员被个性化处理的情境，匿名条件下的被试更倾向于为获取个人利益，利用共享困境情境中的预期合作贡献（p < 0.05）。由于群体边界知觉、外群体同质性与相似性在各实验条件下均未出现系统性差异，本文最后对本研究的理论启示进行了讨论。
