Abstract:

The goal of this 18-month project was to validate and extend a framework for the continuous and quantitative modeling of the neurodynamics of Submarine Piloting and Navigation teams. The studies reported indicate that the use of EEG technologies coupled with nonlinear dynamical modeling approaches, provides a viable approach for studying teamwork over minutes to hours and perhaps longer time scales. The studies show that it is possible to create a structure of symbols from the cognitive relationships of different team members such that the short and long-term linear relationships among those symbols represents a collection of teamwork structures that change over time. The structure of the neurophysiologic data streams is dynamic and multifractal with short-term persistence and longer-term correlations. The structure changes in response to major changes in the task, can be disrupted by internal and external perturbations to the task and team, and reveals novice expert differences. Furthermore, team training factors, including training type and level of team experience, simultaneously impact team neurophysiology and communication in related ways. Challenges remain before this technology becomes routine, but as these capabilities mature we believe these models will accelerate our understanding of the workings of real teams performing real tasks in real environments.
