This study examined relationships between participation and performance within a team and performance transfer effects between opponents in an Emergency Response (ER) simulation. Classical organizational theories have emphasized the importance of group participation for organizational performance, but there have been few or no attempts to investigate participation-performance relationships in short-interval time series. The experimental task was a Stag Hunt game, as defined in game theory; performance trends would be affected by levels of participation, which in turn should be affected by recent performance experiences that modulate the players' self-efficacy for the task. Participants were 62 undergraduates who were organized into 11 teams of 3 or 4 members playing an ER board game against one attacker. Time series analyses were conducted through nonlinear regression with exponential structural equations and by linear analyses for comparison. Results showed that performance time series of one opponent did not affect the other for teams of this size. Teams showed higher levels of adaptability compared to attackers, as evidenced by higher Lyapunov exponents. Performance affected group participation levels more so than the other way around. There appeared to be emergent group dynamics occurring between two experimental sessions that moderated the validity of the core linear and nonlinear models. Emergent group properties are one of several possible directions for further investigation within this experimental paradigm. Nonlinear models were more accurate than linear models after correcting for correlated residuals.
本研究考察了应急响应(ER)模拟中团队内部参与度与表现之间的关系,以及对手之间的表现转移效应。经典组织理论强调群体参与对组织绩效的重要性,但很少有人尝试在短时间间隔的时间序列中研究参与度与表现之间的关系。实验任务是博弈论中定义的“猎鹿博弈”;表现趋势会受到参与度水平的影响,而参与度水平反过来又会受到近期表现经历的影响,这些经历会调节参与者对任务的自我效能感。参与者是62名本科生,他们被分成11个由3或4名成员组成的团队,与一名攻击者进行ER棋盘游戏。通过带有指数结构方程的非线性回归以及用于比较的线性分析进行时间序列分析。结果表明,对于这种规模的团队,一个对手的表现时间序列不会影响另一个对手。与攻击者相比,团队表现出更高的适应水平,这由更高的李雅普诺夫指数证明。表现对群体参与度水平的影响大于相反的情况。在两个实验环节之间似乎出现了新兴的群体动态,这调节了核心线性和非线性模型的有效性。新兴群体属性是在这个实验范式内进一步研究的几个可能方向之一。在对相关残差进行校正后,非线性模型比线性模型更准确。
