This may not be something everyone here can relate to; as I understand things, I'm in the minority as I DON'T think visually and in fact have tremendous problems processing things I'm looking at. I can't remember faces very well, much to my embarrassment, and when I think, daydream or recall (well, the latter two involve thinking...but you get the idea), it's in sounds primarily, with, sometimes, shadowy images.
But the worst problem I have is when there's a lot of "stuff" to look at all at once. Remember those old tests, "Stare at this picture for 2 minutes, then turn the page and answer the questions?" I have ALWAYS been a failure at those.
I also have severe depth perception issues...I'll go to catch a ball, am 100% certain of where it's going to, lift the mitt and the ball falls down next to me. So, stuff like that.
The mechanism is: I see "lots of stuff" all together - on a page, on the TV, IRL (grocery stores UGHHHHHHHHHHHHHH! Confusion!) or wherever, and all of a sudden I just can't...understand any of them. I instinctively strain my eyes harder although it's not technically a vision acuity problem at all. All of a sudden, everything is a jumble and nothing makes sense.
With this said, my son is learning violin. I have always wanted to learn an instrument, started several times with the violin, flute and recorder but what stopped me was...the sheet music confused me so badly that I'd be in tears, and I'd give things up before I really started. But now that my son is learning, I once again have the urge to learn, as I love music so very much. Always have. Anyway, I can see the strings, we are starting on the open note strings, E, A, D and G. Piece of cake. I just recall, in my head, the order of the letters. I realize things will get more complex than this, LOL, but...so far, so good. (For my son, too.)
But when trying to "read" the notes while playing them...OMG. Where's E again? Where's A? And why? I semi-remember a few tricks...for example, FACE going upward in the open spaces. But then I have to "count" those upward to see which it is, then play the note. Rather prohibitive and takes a while!
G is...a few lines down below the staff? Is it two? Three? I JUST looked at it and I can't remember.
What happens is, I see all these shapes and lines that are meaningless to my actual experience, they're all similar - little pointy ovals, some with staffs going up or down - or just...lines and spaces. Which is which, again?
I am so sad about this. I really want to learn. Is this an ASD thing? Or is it something NTs might experience too...is this hard? (I try to guard against deciding "everything" must be due to ASD. Some things just aren't!) Will I ever "get it"? Does anybody else have this visual difficulty, and in particular, has anybody else had this issue with trying to learn to read music and if so, did things improve as you practiced?
