Interaction Effect of Leadership and Communication Media on Feedback Positivity in Virtual Teams
实验研究了领导风格（变革型与交易型）与沟通媒介（虚拟世界或即时消息）如何交互影响虚拟团队中的反馈积极性，并发现反馈积极性与团队满意度、凝聚力等正相关，但与决策质量负相关。
Technology and contextual factors may moderate the effects of leadership in virtual teams. We conducted an experiment to study the effect of leadership styles on feedback positivity in small, ad hoc teams performing a decision-making task using a virtual world or instant messaging. We also examined the relationship of feedback positivity to team outcomes, including satisfaction, social presence, cohesion, group efficacy, consensus, decision quality, and task time. Leadership style interacted with communication medium to influence feedback positivity. Relative to transactional leadership, transformational leadership led to greater feedback positivity in the instant messaging condition but had no effect in the virtual world condition. Greater feedback positivity was positively associated with social presence, discussion satisfaction, cohesion, group efficacy, and task time, but was negatively associated with decision quality.
