Temporal pacing in task forces: Group development or deadline pressure?
研究通过两个实验分离了任务节奏与群体生命周期，发现间断平衡模型中的时间模式反映的是截止日期下的任务节奏，而非群体发展过程。
Research on the punctuated equilibrium model of group development confounded group life span with member tusk completion. We report two studies that separate task pacing, from life span development. In one, 50 students simultaneously performed group and individual projects. In the second, student groups worked on two tasks sequentially. Results indicate that the temporal pattern postulated in the punctuated equilibrium model reflects task pacing under u deadline, rather than the process of group development.
