Outline and evaluate restoration explanations of the functions of sleep [4+16 marks] the two most influential restorative theories are those of oswald (1980) and horne (1988) they propose that sleep serves a restorative function. Outline and evaluate one or more evolutionary explanations for the functions of sleep (24) intro: behaviors evolve, develop if they provide selective advantages for the animal sleep=evolved into an essential behavior and serves an adaptive purpose in the eea. According to the repair and restoration theory of sleep, sleeping is essential for revitalizing and restoring the physiological processes that keep the body and mind healthy and properly functioning this theory suggests that nrem sleep is important for restoring physiological functions, while rem sleep is essential in restoring mental functions.
Sleep, dreams and sleep disorders is the mandatory topic in the individual behaviour unit what you must know about from this topic: (ie you could be asked specifically about it) biological approach and cognitive approach. Outline and evaluate one or more evolutionary explanations for the functions of sleep (8 + 16) according to the evolutionary approach, the function of sleep serves an adaptive purpose and sleeping patterns have evolved naturally in order to promote survival. Outline and evaluate the restoration theory as an explanation of the function of sleep according to restoration theories, the purpose is to repair and renew the brain and the body through restoring energy resources, repair and growth of tissue cells and muscles and replenishing neurotransmitters.
Restoration theory proposes that sleep is a time for restoration of physiological systems, especially the brain, that are active during the day for example, oswald (1980) found that damage to the brain through a drug overdose, increased the amount of rem sleep in an individual this suggests that. The restoration theory states that the function of rem is for brain growth and repair, because babies have long periods of active sleep, this helps their brains to develop and learn the credibility of the restoration theory is further increased in light of the fact that babies that are born prematurely can spend up to 90% of their sleep in rem. Outline and evaluate one or more evolutionary explanations for the function of sleep plan study play para 1 predator avoidance sleep constrained by predation risk. November 20, 2014 november 20, 2014 sheywood biological rhythms, sleep and sleep disorders: a2 level function of sleep, restoration theory, sleep, sleep deprivation ao1 according to the restoration theory, the function of sleep is to restore the brain and body by replenishing the levels of neurochemicals and restoring energy.
In evaluating restoration explanations of the function of sleep, it is key to point out that many animals that are largely inactive, sleep for extended periods of time, such as the giant sloth which sleeps 20 hours despite its low energy expenditure. Outline the lifespan changes in patterns of sleep for each age group there are major chnages in sleep as humans grow from infancy to old age, for example the amount and kind of sleep we experience infancy: infants tend to sleep about 16 hours a day (it is not continuous), shorter sleep cycles then adults. Evolutionary explanations of sleep have an adaptive purpose to maximise the chances of survival and pass on the genes to offspring one of the main features of the evolutionary explanation is sleep conservation, as proposed by webb (1982. The restoration explanation suggests that sleep allows biological systems to return to optimal working order during slow wave sleep (sws), growth hormone is secreted, which stimulates growth in childhood and in adulthood are vital for the restoration of body tissue as it enables protein synthesis and cell growth.
Outline and evaluate restoration theory as an explanation of the function of sleep (8+16 marks) sleep is believed to function as a means of restoring the biological system to a better working order this is the basis of the restoration theory, sleep is divided into several different stages such as sws, and rem sleep, oswald proposed that each of these sleep stages has a different restorative. The final stage of sleep, called rapid eye movement (or rem) sleep is characterized by random, jerky eye movement, fast, shallow breathing, and the temporarily paralysis of one's limbs. Below is an essay on functions of sleep from anti essays, your source for research papers, essays, and term paper examples outline and evaluate one explanation for the functions of sleep according to the restoration theory, sleep helps humans restore themselves to full functioning capacity. Outline and evaluate restoration explanations of the function of sleep (8+16 marks) outline and evaluate evolutionary explanation of the function of sleep (8+16 marks) describe and evaluate explanations for insomnia (8+16 marks. Apart from being of general interest, you may be able to incorporate some of the information into an essay on sleep function or use it to evaluate one of the two main theories anecdotal evidence is provided by the way we feel so refreshed and renewed after a good night's sleep.
Restoration theories suggest that the function of sleep is to repair and restore the brain and body if this did not happen, then the functioning of the brain and body would gradually break down. Sleep patterns may be more due to genome lag, which occurs because the environment changes much more quickly than the genes, and the introduction of electricity may account for the decrease in hours of sleep as we are now able to stay awake for longer. Outline and evaluate one restoration account of the function of sleep essay sample the restoration theory of sleep map is carried out by oswald who argues that the intent of slumber is to reconstruct low energy militias extinguish waste merchandises from musculuss fix cells and retrieve physical abilities that have been lost during the.
Sleep 'outline and evaluate the restoration theory as a function of sleep' (8 marks + 16 marks. The restoration theory says we sleep to restore the body's ability to function at the end of the day oswald said that short-wave sleep (sws) is for restoring the body in terms of physical activity, whilst rem sleep is for resting the brain functions. The importance of restorative sleep and sleep continuity for adult humans, restorative sleep should account for 50% of the total night's sleep, evenly divided between stage n3 delta and stage rem sleep at 20-25% each. Published: mon, 5 dec 2016 sleep is known as the circadian rhythms it's mean sleep-wake cycle one cycle is one day and controlled by the hypothalamus sleep is very important to each person.
