Ive seen the video with the gorilla before years ago and it still nearly got me (I was busy counting how many times the ball was being passed ) and then I noticed something not right and remembered I had seen this before! This shows how strong our selective attention can be!
I work in a school and it is so bust but just about no matter what you can always hear your own name being called (your brain is tuned in to hearing this and filtering out 'white noise' (which there is lots of at work so I have become a pro at this!)
Right! Another fascinating fact is that even if a child is separated from his mom at both, he will always hear her voice in a crowd. Even if he doesn't know why her voice is standing out...
Yeah that sound right as it fits with attachment theory.
