This gotta be my favorite comment in the entire thread. I take three tests: PVT, a video game, SAT -- and I get accused of "just playing video games" and told to perform a broader spectrum of assessments.
I'm not familiar with PVT, and from the description I thought it seemed itself like a simple (if boring) videogame - or at least measured a subset of similar skills, like reaction time and attention lapse.
Didn't mean to come across as dismissive; I really am interested in broader metrics on this stuff. But don't deprive yourself again just for our sake. Thanks for your work, for reiterating the SAT piece, and for stimulating some great HN discussion.
(ps. You attributed some of the minor, sleep-deprived PVT and SAT deterioration to "getting lost in thought". Do you think you'd encounter the same degree of boredom or drifting focus if you did them again post-experiment, in a well-rested state?)
PVT is a standard in psychology task used to assess sleepiness - no relation to video games
Note that the "getting lost in thought" happened when I slept 8 hours not 4. I think it just came to me taking hours upon hours of very similar tasks.
>I was extremely bored in the last 2 days of taking control measurements and sometimes got distracted and lost in thought, which resulted in me getting 3 and 4 lapses per session (as can be seen on Figure 1). I do not believe that these lapses represent my lack of alertness. ...
>The last low control score on the verbal section is a result of me becoming very bored with taking the SAT 5 days in a row, getting lost in thought for 10 minutes, and having to rush.
I will continue to experiment with sleep, mostly for myself :) and I'm planning to test memory and skill acquisition next time -- these are the two things people say are affected the most, so I'll try to figure out if that is true for me.
