On Perceptions

This is my favorite illustration about attention and perception. The original page is here.
In the movie below you will see a group of college students passing a basketball.  Some are wearing black shirts and some are wearing white. You must count the number of times the WHITE team bounces the ball between two players. Keep track of the total.
Go ahead and do it. I’ll wait.

Now, watch the movie again, but don’t count anything. Just watch.
Did you see anything you missed the first time?

I have shared this around quite a bit since I found it, and in my experience, less than half of the viewers see the something extra the first time.
This is called Inattentional Blindness.
