Maybe a lot faster than you think. If you only count in the usual way you’d best give up before you even start. If you’re willing to see what your mind can really do, then go on…
A series of dots will flash on the screen. You’ll have somewhere around one or two seconds to type in the number of dots you see. There will be no way for you to actually count the dots one by one so you’ll have to rely on your ability to make a split second response if you want to get ANY answer correct on this test.
Does that sound like a good challenge?
Try it for yourself.
