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.


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.
