Describe the effects of partial, and selective sleep deprivation

What will be an ideal response?

Partial sleep deprivation occurs when people make do with substantially less sleep then normal over a period of time. This is associated with impaired attention, reaction time, motor coordination, and decision making. It may also negatively affect endocrine and immune functioning. Sleep deprivation also appears to play a role in many motor vehicle accidents.

The existence of distinct sleep stages implies that each stage may have its own function. To investigate this possibility, researchers have selectively deprived subjects of either REM sleep or slow-wave sleep. In both kinds of selective deprivation, subjects experience an increased need for that stage of sleep specifically. In addition, both REM deprivation and slow-wave deprivation produce a "rebound effect" in which subjects make up for lost time when allowed to sleep normally again. Studies suggest that REM and slow-wave sleep contribute to the firming up (consolidation) of learning that takes place during the day.
