The contractor conducted research to: establish the magnitude and duration of sleep inertia after waking from short episodes of sleep; determine how the level and time course of sleep inertia varies according to circadian phase; and determine how the level and time course of sleep inertia varies according to the duration of prior waking. The specific objectives were 1. To determine the magnitude of any decrements in performance and subjective and/or neurophysiological alertness upon waking from naps ending at 0200 hrs (after about 20 hrs awake), compared to the 'no nap' condition, 2. To determine the time course for any decrements to return to baseline levels (compared to the no-nap condition). 3. To determine whether the nap (duration, proportion of SWS or sleep stage on awakening) influences the magnitude or time course of sleep inertia effects under these conditions. |
