Sixty four healthy volunteers, aged 20 to 36 years, were grouped in teams of four. Eight teams were military (24 males and 8 females) and 8 were civilian (17 males and 15 females). Fifty six subjects were randomly assigned either to a feedback or no feedback condition and 8 military subjects did a control condition (solo condition). Participants were equipped for continuous ambulatory recording of EEG, EOG and EMG and completed 14 x 2-hour experimental blocks during the sleep deprivation portion of the experiment. Subjects completed two additional 25-min team task sessions (before and after the nap) to study the effects of sleep inertia on team performance. The Team and Individual Threat Assessment Network (TITAN), was used in this experiment to investigate team decision making. A two-hour nap was scheduled between 1330 and 1530 hrs after 30.5 hrs of sleep loss. Titan performance showed that whether subjects were performing in teams or individually they suffered from significant sleep inertia impairments immediately upon awakening from the nap. However, teams were able to improve their performance with time awake whereas individual performance was still affected by sleep inertia by the end of the 24 min session. TRUNCATED
