In a multisource, lagged design field study of 66 consulting teams, we investigated the role of leader mood in unlocking the performance potential of functionally diverse teams. In line with our hypotheses, we found that, given high levels of leader positive mood, functional diversity was positively related to collective team identification. In contrast, given high levels of leader negative mood, functional diversity was positively associated with information elaboration in teams. Furthermore, results showed that functional diversity was most strongly related to team performance when both leader positive mood and leader negative mood were high. This study highlights the value of examining seemingly contradictory leadership aspects in the effort to gain a fuller understanding of how to foster performance in diverse teams.

发挥职能多元化团队的潜能：领导情绪的反常作用

在对66个咨询团队进行的多源，滞后设计现场研究中，我们调查了领导者情绪在释放功能多样的团队的绩效潜力中的作用。根据我们的假设，我们发现，在领导者积极情绪高水平的情况下，功能多样性与集体团队认同成正相关。相反，鉴于领导者的负面情绪很高，功能多样性与团队中的信息阐述正相关。此外，结果表明，当领导者的积极情绪和领导者的消极情绪都很高时，功能多样性与团队绩效密切相关。这项研究突出了检查看似相互矛盾的领导方面的价值，以使他们对如何提高不同团队的绩效有更全面的了解。
