Statistical analysis of baseline nocturnal EEG profiles identified two groups of S s (a restless and quiet set) who differed in their performance efficiency under acute sleep deprivation. The restless group with less slow‐wave sleep, more body movements, more awakenings, more transitions from stage to stage, and longer sleep latencies showed greatest sleep‐loss decrement. On the first night of recovery sleep, the sleep profiles of the two groups were virtually identical, but by the third recovery night, the restless group was again showing signs of disturbed sleep. Within each group, all S s had highly systematic stage‐of‐sleep cycles, forming Markov chains of at least order one.
