Ah ha! there. Hard to explain why this is cool to me. Back in 1990/91, I studied a bit about neural networking (the stuff of Artificial Intelligence), which was based on a very old model of "how neurons might work" from back in the 1940s/50s based on weighing perceived significance on edges connected to nodes. Wait, no, easier: "Why is this connection important? I'll give it a score of 58%" "Oh wait but no, this thing over here is ALSO important with a significance of 80%", "CRAP! I'd better update that 58% and make it a 27%" One of those "everything affects everything else" type things. Anyway, it works *REALLY WELL* but it's _slow_ as heck if that's ALL you're using to sort out the world. Thousands of tries to figure out "simple things" when used on computers. [still awesome of course] Anyway, 2nd line in this, which is about the Event Horizon Model - same theory used to explain why we forget things passing through doorways... meant something to me. While some form of "weighted importance" may be true for sorting out long term memory when it enters working memory... [gotta throw out the expectation of finding pickles or poop when your mind pulls forward smells of pickles or poop when someone gives you bad news because it's irrelevant] - it DOESN'T account for stepping through life from event to event, why we forget someone's name we *just met* as we go into the car to leave, or a ringing phone can make us lose our "train of thought" so quickly. Weights are nice for pulling forward old memories for filling in gaps of knowledge about the present moment - but not a very efficient system for juggling working memory. Too big and clumsy. Working memory is a very speedy sorter, and is agile and goes from event to event, resetting itself whenever SOMETHING big enough changing, tossing the old working memory in compressed form back into Long Term Memory.... or maybe some kind of inbetween memory. [these are conceptual "buckets" - not tangible ones, I don't think] Oh, and #5 is interesting: It's the reason why we can't find the car in the parking lot: It's because EVERY MEMORY of EVERY car in EVERY parking lot is overlapping with each other.... and it's really hard, especially when it's the SAME parking lot, different place, to distinguish one event from the other... because they're all practically the same every time.[1]event-horizon-model References Visible links 1. http://icopiedyou.com/wp-content/uploads/2015/08/event-horizon-model.jpg
