- Restoration theories
- Physiological patterns associated with sleep are produced by the recovery processes of the body
- Oswald
- People recovering from trauma e.g. drug overdoses sleep more time in REM sleep
- Skin cells grow more in sleep. This can be linked to increased release of growth hormones during deep NREM sleep.
- Concluded that REM was for recovery of brain while NREM for the body
- He predicted that burning up resources during the day will result in longer sleep
- sleep deprivation will effect brain function and behaviour
- Effects of sleep deprivation
- People can endure long periods of sleep deprivations with no effects
- Can effect mental functioning but the effects vary per person
- afterwards, only a small proportion of sleep lost is recovered
- Recovery is concentrated on the deep stages of NREM or REM
- Horne's restoration
- Sleep- deprived participants given cognitive tasks could maintain reasonable cognitive functions
- eventually deprivation produces effects on memory and attention
- moderate sleep deprivation appears to have few if any effects on the body
- When allowed to sleep, deprived participants make up far more of the REM or NREM sleep that they have lost
- Sleep- deprived participants given cognitive tasks could maintain reasonable cognitive functions
