Restoration theory AO2
- Sleep deprivation
- Total deprivation
- case studies such as Peter Tripp who stayed awake for 201
hours and suffered psychotic episodes
- as a result support the idea that sleep is for
restoration of brain and neurostransmitters
- Randy Gardner stayed awake for 260 hours - did
not have the same effects as Tripp
- does not support findings that sleep
deprivation causes psychotic episodes
- case studies such as Peter Tripp who stayed awake for 201
hours and suffered psychotic episodes
- Partial deprivation
- if denied REM sleep participants
spend more sleep in REM
- suggests that REM sleep is more
important for us than other stages
- studies done in a laboratory in order to record sleep patterns
- therefore lack ecological validity
- therefore lack ecological validity
- we are unlikely to get a normal nights sleep in a laboratory
whilst wired to machines
- if denied REM sleep participants
spend more sleep in REM
- Total deprivation
- Endurance athletes
- Shapiro et al found that athletes such as marathon
runners sleep for longer after the event than usual
- suggesting that sleep does aid restoration
- suggesting that sleep does aid restoration
- however other studies do not support these findings
- while such athletes fell asleep quicker they did not sleep for longer
- Shapiro et al found that athletes such as marathon
runners sleep for longer after the event than usual
- Amino acids
- Horne argues that the amino acids that are
needed for protein synthesis
- tissue repair and growth are only available for
5 hours after eating
- suggests that protein synthesis
cannot occur during sleep
- casts doubt on
restoration theories
- Horne argues that the amino acids that are
needed for protein synthesis
- IDA
- Case study evaluation
- only represent a small sample of people and
these people are likely to be unique
- will have volunteered for the study and probably
motivated to cope with the deprivation
- therefore be careful in
generalising these findings
- only represent a small sample of people and
these people are likely to be unique
- Animal studies
- experiments on animals suggests sleep
deprivation can lead to death
- supporting restoration theory
- supporting restoration theory
- as well as being unethical, sleep patterns are
different in animals from humans
- procedures used to keep animals awake which may have lead to stress
and this could cause death rather than deprivation
- experiments on animals suggests sleep
deprivation can lead to death
- Case study evaluation
