In a longitudinal field study of 37 professional project teams over almost 2 years, we investigated the dynamic relationship between perceptual shared cognition and team potency in predicting team performance. Our main results show that initial levels and change in perceptual shared cognition explain team performance outcomes through initial levels and change in team potency, respectively. Thereby, our findings confirmed that initial levels and change in team potency operated as an explanatory mechanism for the relationship between shared cognition and team performance. Interestingly, shared cognition change shows larger benefits on team performance outcomes than initial levels. In addition, we show differential relationships of task‐ and time‐related shared cognition with the quality and timeliness criteria of team performance. Whereas shared task cognition predicts team performance in terms of both output quality and timeliness, shared temporal cognition predicts timeliness only. Altogether, this research suggests the unique theoretical value of change in perceptual shared cognition in explaining team performance and of affective‐motivational team states as an alternative explanatory mechanism for the impact of shared cognition on team effectiveness.

感知共享认知和团队效能的动态如何预测团队绩效

在近两年的时间里对37个专业项目团队进行的纵向研究中，我们调查了感知共享认知与团队效能之间在预测团队绩效方面的动态关系。我们的主要结果表明，初始水平和感知共享认知的变化分别通过初始水平和团队效能的变化来解释团队绩效的结果。因此，我们的研究结果证实了团队能力的初始水平和变化是共享认知与团队绩效之间关系的解释机制。有趣的是，共享的认知变化比初始水平显示出更大的团队绩效收益。此外，我们展示了与任务和时间相关的共享认知与团队绩效的质量和及时性标准之间的差异关系。共享任务认知根据输出质量和及时性预测团队绩效，而共享时间认知仅预测及时性。总之，这项研究表明，感知共享认知的变化在解释团队绩效和情感动机团队状态方面的独特理论价值，是共享​​认知对团队效能的影响的另一种解释机制。
