Visual Cognition

Here's another experiment. It's not one of his, but Richard Wiseman introduced me to it at The Amazing Meeting 4 last year. The video was produced by the Professor Daniel Simons at the Visual Cognition Lab at the University of Illinois.

In the video, you'll see a group of college students tossing basketballs around in a hallway. Some are in white shirts, some are in black shirts. The idea is that you have to count the number of times the students in the white shirts touch a basketball. It takes a keen eye to keep track of them as they move around. I can't embed the video for copyright reasons, but you can watch it here, then come back to this page for the second part.

Done?

Okay. Now, go back and watch it again -- the exact same video -- this time keeping an eye on the students in the black shirts, and see if you notice anything you missed the first time.

Note: If you're going to comment on this, please don't give anything away.
