Document Summary

These areas are involved in most cognitive tasks, particularly attention, executive. Each level has a knock-on effect on the next level. Level 3 - executive function (behaviours that allow us to deal with changing environment, goal-oriented behaviour) Level 1 - alertness/arousal (we need alertness for most cognitive tasks) Acute sleep loss > degrades due to time. Chronic sleep loss > degrades cumulatively each day of poor sleep. Time of day/phase > alertness is worse at night. Sleep inertia > alertness is worse on awakening. Presence of sleep disorder > alertness is worse in those with sleep disorders. Karolinska sleepiness scale (kss) and stanford sleepiness scale (sss) > kss used more often than sss as the wording is better. Used to be controversy in the literature over how good people are at determining their own sleepiness > generally people are good. Conducted multiple times, connected to a polysomnography. Measure how long it takes them to fall asleep at each opportunity.
