I have been marveling at how different so many events in my life look to me in retrospect since learning about this. I always faulted myself for not having a powerful enough brain to process all the stimuli all at once. I mean, other people don't have this issue, so clearly my brain is lacking, right? It never occurred to me that maybe others don't have this issue because they don't notice every little thing in a new scene all at once. My husband confirmed this - he notices things in a methodical order when he goes into a new place (for example). This made me feel SOOOO much better. It's not that my brain is lacking the processing ability, it is that my sense of perception is too strong. My husband suggested that it should be looked at as a strength, not a weakness or a 'condition'. I like that idea. I'm going to call it my 'super power'. :p
Anyway, I recalled a situation when I worked in retail. I was the manager of a very large high end outlet store. It was a busy weekend day, and I had probably 25 employees on the sales floor. Customers were everywhere. I had been in the back for some reason and when I came out onto the sales floor, I immediately knew something was wrong. To this day, I can't put a finger on what I saw, but something triggered my awareness and I immediately called in 'reinforcements'. We were under 'attack' by 6-7 members of a professional shoplifting ring. My trained security employees hadn't noticed it but I immediately did. Everyone joked about it at the time, but now I think it must have had something to do with this. Had I not known my own store so well, I might not have picked up on what was out of place admist the overload....but since it was my store and I knew it like I knew my own bedroom, the anomoly stuck out. Funny.
I need to do some more reading because now I am wondering if there is a hereditary aspect to this. My brother is the same way. He would scream about sock seams as a child (I was never that way) and to this day, hates tags in his t-shirts. He also hated (and would freak out) if a restaurant was too loud. I'll have to send him a link to the quiz to see how much else is true for him.
