Comment on Forever young
NikkiDimes@lemmy.world 3 months agoI mean, you say that, but I’m mid 30s >:D
So I said there is a difference of about 200ms. But humans cannot typically react faster than 200-300 ms. Even young people. Because it takes at least 200ms for a signal to be sent. So I’m suspicious of this result.
I used to do research on reaction time. We throw out any number under 200 because it’s considered not humanly possible and it’s an error measurement.
Perhaps there was delays induced by your testing setup? I regularly hover around 150-175ms depending on the day with pretty much any reaction time test.
We account for all of that. We have higher quality equipment to reduce device delays.
Are you sure you aren’t “predicting” ?
Also I really question how accurate the website is. Has it done latency tests on your screen and keyboard and accounted for that? Because maybe it’s using the wrong information and adjusting your score out of humanly possible ranges.
I say this because it takes nearly 150-250 ms just for the visual stimuli to be processed. There is no way around this. en.wikipedia.org/wiki/P200
There are specific processes that occur in the brain that take time to happen. And these are dependent on size of the brain (a very small factor within same specifics,) and myelination. A much bigger factor even within species.
Myelination is essentially the lubricant and insulation for signal wires. Signal travels faster and in higher quality when neuron connections are adequately myelinated.
This is something mostly genetic but can be degraded with diseases like MS and aging.
Of course having stronger pathways from using those pathways often will make them more accurate.
Motor control is , in many ways, the most simple processes the brain does. It’s not that simple. But compared to a lot of other functions it is.
Motor Pathways are mostly mapped out in humans. However, We still don’t understand completely what the cerebellum does but it’s very involved in motor control. (Not initiation tho). Because of the straight forward nature tho of initiating a response we know those hard limits of reaction time for pushing a button after seeing or hearing a stimuli signal.
Also
The best thing for your brain is adequate, efficient, and reactive oxygen supply.
Meaning the heart and vascular system can re route oxygen quickly to various brain areas in response to need.
People want magic vitamins and neurotropic drugs to make themselves smarter but in reality, cardiovascular health is literally number 1.
Keep mine. It really does depend on tests. A lot of the online tests start with a negative offset to account for paying. So a 160 you would typically add anywhere from 30 to 60 on average. The better online tests will actually run a short ping test in jitter test to set the offset more accurately. Most though don’t and just use a fixed value.
My rule of thumb is most of the time the devs just slap a 50 in there surround number and it kind of covers most bases. So a 160 would be a 210. Which for a test where you can do it repeatedly and be hyper fixated on knowing what you’re doing. You can get pretty damn close to 200, not reliably but that’s going to be like you’re 1% best result which is what people f****** posting.
Like for example, my best results in these sort of tests accounting for offsetter between 190 and 210. But that’s like one in 50 tries. Where my normals closer to like like 230.
And usually I have like a 10 millisecond variance on my average tries.
A lot of the online tests start with a negative offset to account for ping.
Why would they do this? The test runs fully in your browser; there is no ping. Whatever it shows you is what it is. I just made my own very simple reaction tester web app and I get the exact same results as Human Benchmark.
oh that’s because you started at -40ms
I was literally Stadia incarnate in my heyday

Imo, this test is flawed and doesn’t take display refresh rate into account. Well, at least flawed in the sense that you can’t compare it to other people because they may have measured it differently on different hardware. Its not universal.
I’m at work right now and using this shitty screen at 60hz, I got 230ms. I upped the refresh rate as fast as it can go, to 75hz and improved my reaction time to 200ms.
To get accurate results, you’d need to do this test at different stages of your life on the same hardware with the same software version of the test. So take it with some salt.

Of course a test like this does not compensate for all variables. Every piece of in the chain is going to have an effect, from mouse, to your specific computer hardware, operating system, all the way to your display output.
That said, I think your delta of 30ms was just variance that would be reduced by averaging several results. The maximum added latency by using 60hz is 16.66ms, while the maximum average for 75hz is 13.33ms, a far cry from the 30ms you experienced.

Honestly, all you actually would need to do is just go to the steam survey, check what the most common hardware is.
Cuz all you got to do is test against that. As if your response time for example is in the top 10% of people. When your baseline is the most common hardware available then you’re in at worst the top 10% of people. Reaction speed changes depending on task just as much as it does on hardware.
Like personally, I take a reaction test using the most common steam hardware and I’m looking at about 150 milliseconds response time by doing it on my normal hardware which is many times faster. In refresh rate it only shaves like two milliseconds off average and it fluctuates just as much. Like two milliseconds off average and it fluctuates just as much.
I even have a little like toy thing that I picked up one day years ago that tests reaction time using a mechanical device. Testing it. It’s within about 5 to 10 milliseconds of variation off of what most digital online tests that I can find.
And it within margin of error shows exactly the same amount of reaction speed that the online tests show.
So they’re accurate enough at least within a handful of milliseconds.
The toys basically just a taser and two people grip a thing. Whoever grips and clicks the thing faster doesn’t get tased its rather fun.
I almost always win even against my younger cousins and step Brothers who are as young as 12. So my 35 year old ass still has it!
Just don’t ask me to have any amount of reaction speed with my legs. Probably try and kick something. I will miss it. By a mile. 3 hours after you threw it.
