Here’s an on-line test that we’ve had some fun with. About 20 images flashed on the screen and your responses are measured to the millisecond. Afterwards it gives you your times for each response, your average, your standard deviation, and some raw score I guess (not sure how to read that.) Anyway, pretty fun.

Tried it 3 times. Raw scores were:
69.92
77.19
73.28
I’m not sure what that’s measuring, however.

Interesting test…not sure what it means, but it was a lovely way to kill a minute or two.

They raw scores seem to be percentages. The top score on the chart is 314. After you do the test, I’m guessing that your scores are averaged against 314 (perfect score?) to get a result.
two raw scores for me:
94.59
96.03

The way I read it is that the “314” (314 milliseconds) is the longest time you took among all of your responses.

Or on a slow connection today. I had to laugh we I saw the “accurate to one millisecond”. Sure, it may be, but there’s no way to compensate for the traffic delays.

Might be … but we also have to remember that we’re talking about a ‘click’ and the speed of light here.

Looks like a flash game so it’s handled local not over the network.
Got 74.something lowest
82.something highest

I notice the site is shilling something. Also that I seemed to be doing way badly on all the tests. Don’t know if there’s any connection there…
I did the “brain aging” test and it told me I had the brain of a 90 year-old :rolleyes:
Where’s my walking stick?

It says 341 in the top left corner, 75.93 in the top center, average 263.3 standard deviation 32.29. How do I interpret that? If I improve do those numbers get higher or lower?

I did this a second time and got, from left to right top to bottom:
292 - seems to be the worst one
80.47 - maybe the percentile?
248.5 - Average of all tests
22.53 - standard deviation (shows consistency)
Fastest I can see from the numbers at the bottom is 221 milliseconds.

My average was 63.92, but I’m too dumb to understand what that’s supposed to represent.

90.2 now. Whoot, I think!

I figured they’d need a calender to measure mine, I’m terrible at this type of thing. Anyhow, here you are:
292
67.96
Average - 294.2
St. Dev. - 27.45
As you might imagine, I’m terrible at videogames.

For the first score it is definately the higher the better (probably a percentile of all tests). I tried to be particularly slow and got 40.2 but by trying to be fast got 70.7
I wonder how much your keyboard will effect the scores, as in how far you need to press the down arrow key before it is registered?

So I’m fastest so far…good.
I would have been very surprised had it been otherwise.

Well according to their charts, we all have the reaction times of 80 and 90 year olds. Me being in the 80 range 🙂 … that said, I also have the “Brain Age” of a 90 year old. And, if I have to say it myself, I still look damn good.
Link to the “Brain Age” test.

I took it again. I’m almost certain that the the top number is a percentage against tests.
Until someone can beat my 96, I claim the fastest finger title.
