Patient discussion about deprivation

Q. what are the affects of sleep deprivation, and can I counteract them? I’m a college student and I’ve been sleeping for 5-6 hours a night for the past month…what symptoms should I expect? And how can I counteract them?

A. I studied this just 2 days ago:

Studies on sleep deprivation are actually beginning to show that people do not require as much sleep as traditionally taught. While sleep deficits effect first auditory acuity, and can even cause people to go into what are called microsleeps, researchers are finding that when people are being deprived of sleep they actually sleep more efficiently (spending more time in stages 3 and 4 of sleep) The problem is that people do not train themselves properly to shortened sleep periods, thus stuggle to adapt when they cannot receive the customary eight hours. Ideally, with adequate control and preperation, people can sleep for 4 hours a night and be fully cognatively functional.

Just thought you'de find that interesting

What is new in this paper is that we provide a comprehensive summary of the evidence--more comprehensive we believe than any other review to date--and also introduce a new perspective on the ontogenetic origins of depravity, namely, what is known from animal and human research about the long-term effects of maternal deprivation.

The body of literature that we refer to is the research on maternal deprivation, which includes studies involving both animals and humans (studies of postinstitutionalized children raised by adoptive parents).
We will use the term maternal deprivation to refer to the wide range of possibilities here, including maternal privation--being deprived of maternal care from birth--and maternal deprivation--being separated from the biological mother after some period of maternal care (Ainsworth, 1962; Gandelman, 1992).
