The Restoration Theory Of Sleep
The function of sleep is to allow the body to be repaired/ restored
Hartmann (1973) said that REM sleep is a time for making neurotransmitters to compensate for the amount used during the day. Stern and Morgane (1974) also thought that REM sleep allows the brain to restore levels of neurotransmitters to 'factory settings'. Oswald (1980) claimed that NREM sleep restored the body and REM sleep restored the brain, through protein synthesis and that Slow Wave Sleep (SWS) helped the body restore itself. Horne (1988) distinguished between core (SWS & REM) sleep and optional (stages 1 to 3) sleep
The main predictions of Restoration Theory are: Deficits in functioning when sleep deprived 'Rebound' effects following sleep deprivation Increase in REM sleep during brain growth, reorganiation and repair Increase in SWS during times of illness or injury
Deficits when sleep deprived? Peter Tripp 201 hours Randy Gardner, a 17 year old student, stayed awake for 11 days (260)
Rebound effects? Dement (1960) PPs deprived of REM sleep seemed to have a need to catch up Attempts to enter REM sleep doubled from an average of 12 to 26 times by the seventh night. When allowed to sleep normally the participants spent much longer than normal in REM sleep, as did Randy Gardner.
Increase in REM sleep during brain growth and repair?
Total sleep time increases during illness REM increases during recovery from brain injury, ECT & drug withdrawal
Evaluation The FACE VALIDITY of this theory is high – it makes sense. Extrapolating from hamsters, cats and rats to humans is always risky. The research is not always RELIABLE and so we might question its VALIDITY. (cf human sleep deprivation studies and animal sleep depriavation studies – fatal or not fatal? ) Case Studies- 'Alien Among Us' criticism It is easy to obtain quantitative (OBJECTIVE? ) data on REM, amount of neurotransmitters etc
The main problem. . . is the lack of death among humans who are sleep deprived!!
