What the study found
Repeated sleep restriction produced cumulative cognitive performance deficits that subjective sleepiness did not fully track.
Scope & limitations
48 healthy adults aged 21–38; experiments included 14 nights of restricted time in bed
The laboratory design controlled sleep opportunities and measurement conditions. Findings demonstrate cumulative performance changes; individual recovery timing and everyday settings require separate observation.
Population & sample
48 healthy adults aged 21–38; experiments included 14 nights of restricted time in bed
Exposure or intervention
4, 6 or 8 hours in bed per night; a separate total-deprivation experiment
Outcomes
Cognitive performance, subjective sleepiness and sleep physiology
Time frame
14 nights of restriction or 3 nights without sleep; 3 baseline and 3 recovery days in each experiment
