摘要
交互记忆系统近来被认为是影响工作团队绩效的重要特性之一。以往的研究局限于实验室样本或者由学生组成的临时团队,该研究从高技术企业中选取190个工作团队作为样本,考查了团队的交互记忆系统与团队中的其它现象之间的关系。研究除了发现Lew is的量表中有两个题目不理想外,还发现交互记忆系统与团队成员之间的信任、合作性目标导向具有显著的正相关,同时交互记忆系统与团队的工作绩效和凝聚力也具有显著的关系。该文在检验团队层次的现象时,通过计算团队成员在相应变量上得分的一致性(rwg)来检查加总分析的合理性,这是从事团队层次的研究中需要遵循的方法。
Transactive memory system （TMS） has been recently identified as an important factor to influence team performance. TMS is the shared division of cognitive labor with respect to the encoding, storage, retrieval, and communication of information from different domains that often develops as team members have better understanding of each other＇s expertise. Accumulating evidence has shown that TMS explains team performance in the laboratory, but few studies have been conduc- ted in field settings because there is no proper TMS measure for field settings. We examined the relationships between TMS and other phenomena with a large sample of 190 high-tech work teams in China. We found that two items in the TMS scale developed by Lewis （2003） should be dropped. Furthermore, our results indicate that, TMS is significantly related to trust among team members and the extent to which team members share a cooperative goal. In addition, TMS is both positively related to team performance rated by the team manager and significantly related to team cohesion. In this study, individual members＇scores on various constructs were aggregated into the corresponding team-level scores, and the high agreement index （rMg） among team members legitimize the aggregation. This method should be followed in examining organizational phenomena at the team/group level.
