Effects of Transformational Leadership and Anonymity on Idea Generation in Computer-Mediated Groups
通过实验室实验，研究了高/低变革型领导风格和匿名性对使用群体决策支持系统的大学生工作小组创意生成的影响，发现高变革型领导提升创意质量，匿名性增加批评性评论。
A laboratory experiment was conducted to evaluate the effects of high and low levels of transformational leadership style and anonymity on 36 undergraduate student work groups using a Group Decision Support System (GDSS) to perform an idea generation task. Transformational leadership was manipulated through confederate leaders who displayed leadership behaviors and entered comments into the GDSS according to scripts. Results of analysis of variance indicated that groups working under high transformational leadership generated more original solutions, supportive remarks, solution clarifications, and questions about solutions and reported higher levels of perceived performance, extra effort, and satisfaction with the leader than groups working under low transformational leadership. Results also indicated that anonymous groups generated more critical comments and less problem clarifications than identified groups. Implications of these results for organizational researchers and managers are discussed.
