We See Only What We Want to See

You may remember me talking about brain filtering; how our brain filters out what it doesn’t want to pay attention to. You could call it “selective sight”. For you married individuals out there, this is similar to “selective hearing” that plagues inattentive spouses. (I know I’m guilty of it.) I ran across some fun experiments that illustrate this phenomenon.

Simply put, the brain would get overloaded if it analyzed in detail everything we saw. Therefore, it ignores much of what the eyes see. Here’s a video I think you’ll find interesting.

The next video was shown to me in optometry school a few years ago. Play along and do the experiment yourself while watching the video. You’ll be amazed! Just click on this link. While watching the video, try to count the number of times the basketball is passed. Then watch it again, but this time just watch the video.
