DescriptionTeam members co-regulate their activities and move together at the collective level of behavior while coordinating their actions toward shared goals. In parallel with team processes, team members need to resolve uncertainties arising from the changing task and environment. We explored the neurodynamic tension between resolving individual uncertainty and participating in collaborative processes during high fidelity team training.
Electroencephalography (EEG) was collected from five two-person medical flight teams and following pre-processing to remove non-brain signals the interbrain coherence (IBC) were estimated by wavelet coherence and compared with the neurodynamic information (NI) of each individual, a measure that maps closely with person’s uncertainty.
Analysis of the IBC and NI on a second-by-second basis showed that the dynamics of each were mutually exclusive suggesting that the factors elevating and resolving NI levels are single person processes and that the involvement of interbrain processes is minimal.
