When Power Makes Others Speechless: The Negative Impact of Leader Power on Team Performance
研究发现，正式领导者的权力感会导致言语主导，减少团队沟通，从而降低团队绩效，且这种效应仅在领导者拥有正式职位时出现。
We examine the impact of the subjective experience of power on leadership dynamics and team performance and find that the psychological effect of power on formal leaders spills over to affect team performance. We argue that a formal leader's experience of heightened power produces verbal dominance, which reduces team communication and consequently diminishes performance. Importantly, because these dynamics rely on the acquiescence of other team members to the leader's dominant behavior, the effects only emerge when the leader holds a formal leadership position. Three studies offer consistent support for this argument. The implications for theory and practice are discussed.
