The process by which an initially leaderless group differentiates into one containing leadership and secondary role structures was examined using the swallowtail catastrophe model and principles of selforganization. The objectives were to identify the control variables in the process of leadership emergence in creative problem solving groups and production groups. In the first of two experiments, groups of university students (total N = 114) played a creative problem solving game. Participants later rated each other on leadership behavior, styles, and variables related to the process of conversation. A performance quality measure was included also. Control parameters in the swallowtail catastrophe model were identified through a combination of factor analysis and nonlinear regression. Leaders displayed a broad spectrum of behaviors in the general categories of Controlling the Conversation and Creativity in their role-play. In the second experiment, groups of university students (total N = 197) engaged in a laboratory work experiment that had a substantial production goal component. The same system of ratings and modeling strategy was used along with a work production measure. Leaders in the production task emerged to the extent that they exhibited control over both the creative and production aspects of the task, they could keep tension low, and the externally imposed production goals were realistic.
运用燕尾突变模型和自组织原理,研究了一个最初无领导的群体分化为一个包含领导和次要角色结构的群体的过程。目的是确定创造性问题解决小组和生产小组中领导出现过程中的控制变量。在两个实验中的第一个实验中,大学生群体(总人数N = 114)进行了一场创造性问题解决游戏。参与者随后根据领导行为、风格以及与对话过程相关的变量对彼此进行评分。还纳入了一项绩效质量衡量指标。通过因子分析和非线性回归相结合的方法确定了燕尾突变模型中的控制参数。领导者在角色扮演中,在“控制对话”和“创造力”这两个一般类别中表现出了广泛的行为。在第二个实验中,大学生群体(总人数N = 197)参与了一项具有大量生产目标成分的实验室工作实验。使用了相同的评分系统和建模策略以及一项工作生产衡量指标。生产任务中的领导者出现的程度取决于他们对任务的创造性和生产性方面都能进行控制,能够保持低紧张度,并且外部设定的生产目标是现实的。
