Ok, I'm giving a free ISCID membership away to the first person who can come up with the correct answer tp this counting problem:
Here's the task: You'll watch a video. There will be three people with white shirts and three people with black shirts. They will all be passing basketballs. You want to focus on the people with the *white shirts* and keep count of the number of passes between people with only white shirts (not black). It is actually much more difficult than you might suppose. Once you've done the experiment, post an answer. One guess per person. The first person to get the answer right gets a free 1 year membership to ISCID. If you know the answer already, please refrain from posting.

LOL I was too impatient to watch it. But is the gorilla a "black shirt"?
(I saw his shadow before he even entered the scene. Doesn't that screw up the whole experiment as proposed? Is that what you IDers are good for?!... LOL Aren't you just a bunch of subversives?! They have a place for you in the Lubyanka.)
Is that the 800-pound "gorilla" you guys keep talking about? (I think the gorilla was about 160.)

Janitor,
I've heard that 50-70% of those who are intensely focused on the experiment miss the gorilla on the first scan. I know I did ![[Razz]](tongue.gif)

This really IS difficult. There are at least three passes in there where it could be that a black shirted player passes to a white shirted player and vice versa. The Gorilla messes everything up. There also appears to be on very quick, sneaky pass as the gorilla passes through.
If I'm right about those, then I think there's only 12 passes directly from white to white.

The experiment is to make you not notice the gorilla, not to make you count the number of passes. When I am intently trying to count passes between white-shirted people, I can't tell that the gorilla is a gorilla and not a black-shirt, even though I know from previous viewings that it must be there.
It is equally hard to count passes between black shirts, but then the gorilla becomes exceedingly obvious.
It's a very amusing demonstration of the cognitive/perceptual effect of selective attention.
