Concentrating blocks out distractors? Errr... Isn't that why we concentrate? I mean, I guess I understand the concept of "your mind does x" but this is hardly worthy of a post. If I exclude all other things from my input than that which I want to measure, aren't I, by virtue of the act, expected to miss things?

Now, if you had claimed that even superficial concentration results in high percentage of peripheral data being lost then I would say "ok..." But this only works if you attempt exclusion of all else. I was able to count the ball passings AND notice the anomoly quite easily - barely any effort. I fail to see what this proves other than "if you concentrate on comething, you only see that one thing..." which is the point of concentration in my mind...
