Three experiments tested the hypothesis that implicit preferences for racial ingroup members are reduced when external mechanisms are available to incentivize cooperation between individuals. Study 1 varied the presence (vs. absence) of a third-party punisher in a series of upcoming cross-group trust games. Studies 2 and 3 held the presence of a punisher constant, but varied the punisher's likely effectiveness at incentivizing cooperation by manipulating the punisher's group membership or whether the punisher's presence was common knowledge. The results of S1 and S2 showed that anticipating an effective third party punisher reduced racial bias on an intervening evaluative priming measure. S3 was more equivocal, but overall (and as indexed by a multilevel meta-analysis) the findings across studies provide evidence for situational tuning of rapid evaluative responses as a function of contextually variable cooperative affordances.

动态调整评估：内隐的种族态度对团体间合作的动机敏感

三个实验检验了以下假设：当外部机制可用于激励个人之间的合作时，种族内族成员的内隐偏好会降低。研究1在即将到来的跨群体信任游戏中改变了第三方惩罚者的存在（相对于缺席）。研究2和3保持惩罚者的存在不变，但是通过操纵惩罚者的组成员身份或惩罚者的存在是否是公知常识，改变了惩罚者在激励合作方面的可能效力。S1和S2的结果表明，预期有效的第三方惩罚者会减少干预性评估启动措施上的种族偏见。S3比较模棱两可
