The authors describe two research experiments exploring the influence of race on the Köhler motivation gain effect with exercise tasks. Experiment 1 tested whether partner racial dissimilarity affects individual performance. Experiment 2 created a team identity recategorization intervention to potentially counter the influence on performance observed in Experiment 1. White male participants were partnered with either a Black or Asian partner (Experiment 1) or with a Black partner utilizing team names and shirt colors as a team identity recategorization strategy (Experiment 2). Racially dissimilar dyads completed two sets of abdominal plank exercises with a Köhler conjunctive task paradigm (stronger partner; team performance outcome dependent upon the weaker-ability participant’s performance). The results of Experiment 1 suggest attenuation of the previously successful group motivation gain effect in the racially dissimilar condition. The simple recategorization strategy utilized in Experiment 2 appeared to reverse motivation losses under conjunctive-task conditions in racially dissimilar exercise dyads.

作者描述了两个研究实验，探索种族对运动任务的科勒动机增益效应的影响。实验 1 测试了伴侣种族差异是否会影响个人表现。实验 2 创建了一个团队身份重新分类干预，以潜在地抵消实验 1 中观察到的对表现的影响。 白人男性参与者与黑人或亚洲伙伴（实验 1）或使用团队名称和衬衫颜色的黑人伙伴合作身份重新分类策略（实验 2）。种族不同的二人组使用 Köhler 联合任务范式完成了两组腹部平板支撑练习（更强的伙伴；团队表现结果取决于能力较弱的参与者的表现）。实验 1 的结果表明，在种族不同的条件下，先前成功的群体动机增益效应减弱。实验 2 中使用的简单重新分类策略似乎可以在种族不同的运动二元组的联合任务条件下逆转动机损失。
