We explored the possible linkages between expert observational ratings of team performance and the fluctuating neurodynamics of healthcare and submarine navigation teams while they conducted realistic training in natural settings. Second-by-second symbolic representations were created of team member’s electroencephalographic (EEG) power across the 1-40 Hz EEG spectrum, and quantitative estimates of the changing dynamics were calculated from the Shannon entropy of the data streams. Significant correlations were seen between the symbol streams entropy levels and ratings of team performance by observers using TeamSTEPPS® (healthcare), or Submarine Team Behavior Toolkit (submarine teams) rubrics. These results suggest that the frequency, magnitude, and / or durations of the teams’ neurodynamic fluctuations might reflect performance aspects detected by expert raters.
