共享认知对科研团队绩效影响的实证研究

An Empirical Research on the Impact of Shared Cognition on Team Performance

摘要:

自构念提出以来，交互记忆系统与共享心智模型的研究便近乎平行发展，实证探索两大共享认知构念间的复杂关系及其团队影响具有重要意义。以34个科研团队为样本的问卷调查数据表明：交互记忆系统、团队心智模型和任务心智模型分别正向影响团队绩效；交互记忆系统、任务心智模型在团队心智模型与团队绩效的关系中起到中介作用，且两个特定中介效应间差异不显著。由此可见，交互记忆系统和任务心智模型是团队心智模型影响团队绩效的两条同等重要的作用机制。最后讨论了研究启示与未来研究方向。

Abstract:

Researches on transactive memory system and shared mental model have almost developed in parallel since the two constructs were proposed. It is of great significance to explore the complex relationship between transactive memory system and shared mental model, while few empirical studies have been conducted so far. In the paper, we conducted a questionnaire survey with 34 research teams which were conveniently sampled form three universities in China. The results showed that transactive memory system, team mental model and task mental model presented a positively impact on team performance respectively. More than that, transactive memory system and task mental model mediated the relationship between team mental model and team performance, and the difference between the two sepcific mediating effects was non-significant at 0.05 level. Furethermore, the correlation between transactive memory system and task mental model became non-significant after the effect of the team's mental model was controlled. Therefore, there are two equally important but different mechanisms—transactive memory system and task mental model—for team mental model to influence team performance. Finally, we discussed the implications for our findings and directions for future research.
