In that getting insufficient and/or

In that getting insufficient and/or poor
quality sleep has been shown to affect one's
decision making skills, Todd Maddox, from
University of Texas at Austin (USA), and
colleagues studied 49 West Point military
cadets, subjecting 21 of them to sleep deprivation
and monitoring all subjects for their capacity
to make split-second decisions. The researchers
found that moderate sleep deprivation caused
an overall immediate loss of information-integration
thought capacities, with accuracy on the
test tasks declining by 2.4% when the participants
were sleep deprived and improving by 4.3%
when they were well rested. According to
the findings, people who rely more on rule-based
(over-thinking) strategies are more vulnerable
to the ill effects of sleep deprivation.
