The influence of shared mental models on team process and performance

The influence of teammates' shared mental models on team processes and perf ormance was tested using 56 undergraduate dyads who "flew" a series of miss ions on a personal-computer-based flight combat simulation. The authors bat h conceptually and empirically distinguished between teammates' task- and t eam-based mental models and indexed their convergence or "sharedness" using individually completed paired-comparisons matrices analyzed using a networ k-based algorithm. The results illustrated that both shared-team- and task- based mental models related positively to subsequent team process and perfo rmance. Furthermore, ream processes fully mediated the relationship between mental model convergence and team effectiveness. Results are discussed in terms of the role of shared cognitions in team effectiveness and the applic ability of different interventions designed to achieve such convergence.
