Is there any good test for sleep deprivation? I've been wondering if polyphasic sleep really works as well as the proponents tend to believe.

I have been too lazy to check if there are dedicated tests for sleep deprivation, but a timed test of something that you should be able to do quickly and easily would work, right? Sudoku, an easy crossword in your daily paper, any of the online IQ tests. IIRC somewhere in gwern's comment history here he's replying to a guy who did polyphasic sleep for a while who found that after about three days he couldn't learn anything (or so he interpreted it based on being unable to learn any new Anki cards). Apparently one proper deep long sleep reverted that. Check brain workshop for a suite of tests anyway.

0Bobertron9yI think I read somewhere that researchers measure the time someone needs to fall asleep for that.
6Vaniver9yA Psychomotor Vigilance Task [] is what I've been using for my sleep dep experiments. It maps pretty well to my subjective experience of tiredness and reveals my worst moments in all their quantitative horror. (Once, at my worst, it took me about 15 seconds to respond to a stimulus.) If you're trying polyphasic sleep, I would recommend everyman over uberman from my experiences.

During our latest meetup, the DC Less Wrong group has decided that we are interested in experimentally testing various lifehacks on ourselves (on an opt-in volunteer basis of course).

We need two things:

  • Metrics (to actually tell if there's a difference or not, rather than convince ourselves that there is)
  • Things to test

Do any other groups have any measurements that they take to track their various attributes? Anything that they'd be interested in testing?
