Your trigger finger of course your perverts!!!
A friend posted this on a FPS forums, first person shooter forum, to see how fast people can react to something on the screen, as many people cry hacker when someone is faster then them, they dont beleive it.. and cant admit to it! get that, someone out there who could better then you at something..lol 
So for our scenario, if you had to whip out your camera and all settings were good, or you tossed it to sports mode for a fast capture or something , or you were waiting for that perfect moment to shoot.... and didnt want to miss it, like a cat jumping in the air shot type thing...
how fast could you actually get a shot off? would you get it, or would you miss it....
first one is speed, how fast you react, i avereged .25 and i had just woken up about 20 mins before, then i tried later and did worse being awake!
try it out....

it tests speed, but ALSO, it test to see if you almost react better to something more expected. ? or suprise! seems most people react better to a suprise,, or something not expected...
2nd link.... more of a speed and accuracy, i didnt finish it, i got bored..lol
