When I go many days in a row without enough sleep, I find that my cognitive abilities (i.e. what I am capable of doing) does not seem to significantly decline--as judged by things I build and people I interact with. But, my endurance of focus (the amount of time for which I can perform at a high level) does suffer. The weird thing is that it doesn't feel like I can't keep going... it's just that I sort of somehow don…
Since a few years ago (when I read Why We Sleep [0]) I’ve made it my priority above all else to allow myself 8 hours of sleep, even if I don’t ‘use’ all of it. With more sleep, an innumerable amount of things are better (as read in the book), but subjectively I noticed the following after about a month straight of good sleep: * Pain was far more manageable (IBS, MMA injuries) * Sleep was more restorative when I woke…
Instead now I have an alarm to go bed, and I get up when I feel rested.

The guzey_arena_0 test could be biased by his skill level improving over time by playing it regularly, though if he was an avid FPS gamer prior to the guzey_arena_0 tests, the asymptotic growth of skill had probably leveled off in time. I didn't see this addressed in the paper outside of this section: "I will give myself a sleep opportunity of 8 hours (23:30-07:30). I will practice the tasks I’m going to use in order…

It figures that everyone each has their individual baseline "propensity to stay focused"--and sleep deprivation degrades someone's focus below that. You take a normal person and sleep deprive them, and their "propensity to stay focused" is lowered, but still might fall within an acceptable/functional range.
One theory that's gaining traction is that people with ADHD have a somewhat lower baseline than average, and when you throw in sleep deprivation, their "propensity to focus" falls into dysfunctional territory. Ergo, ADHD might have a large sleep component.
In all cases (which corroborates with your experiences), they found that people are really poor at actively self-detecting those fluctuations.

It's very common. Studies on sleep deprivation report that subjects do not feel their cognitive abilities decline. However, measuring cognition using objective tests does show a significant decrease in these abilities.
Was his assessment basically just playing video games? I've noticed that's an activity I can do proficiently for an extended duration on very little sleep (along with things like "bulk" coding) but there are others I'm awful at unless I'm well rested (eg. complex planning, creative efforts like songwriting) and I've found my communication skills start to become impaired when I'm really sleep deprived. I'd be curious…
I once made a giant switch statement of 150 lines at my first coding job, and I thought I did a job well done. The next day I came back, well rested, only to realize that I could replace the whole thing with an already existing csv file and a for loop.
Whoopsie :)
How I differ from your experience: there's a certain sleep deprivation sweet spot where my "outbound communication" (e.g. talking or sympathy) skills are better, because I'm a bit less inhibited. My "inboud communication" (e.g. listening or empathy) do suffer a bit. I've noticed I become more of a doer (is that how you write it?). Normally, I overthink things, according to others. That's not the case when I'm mildly sleep deprived. Then I am: optimistic, charging in head first and get the job done! Boom! Yea, kinda like that, I think I'd be a good sales guy on mild sleep deprivation. Oh, and I don't worry about the consequences too much :)
When I get too sleep deprived my communication skills do take a hit.

What type of video games? That matters a lot to me. I can play a turn-based game like Civilization completely fine on little sleep (measuring the quality of play objectively, like by productivity or victory within a certain number of turns.) Soft real-time games like say a Mario platformer are a little worse but playable if I'm tired. Hard real-time games with very tight and sensitive timing like Guitar Hero or high-…
Games requiring long term focus, chess for example, I personally have difficulty playing when sleep deprived, even though it is turn based. I find I play at ~200 rating points lower on low sleep.
Games that require fast response and planning suffer on one extreme, and abstract thinking games like chess suffer on the other.

Just recently since I've been working from home all the time, I realized I don't actually need an alarm to get up, since I don't need to leave the house at a predetermined time to beat traffic and get to the office at a reasonable time. Getting up at the same time in the morning was just habit. Instead now I have an alarm to go bed, and I get up when I feel rested.
