I was rated a 92% stickler, but I don't think you should put commas after 'or' (or 'and', mostly), so I don't agree with their rating - in reality I'm a 100% punctuation stickler, but with a modern take on punctuation.
I took part in an interesting email discussion recently about spelling. How do some people become good spellers while some intelligent and successful people can't spell? You could ask a similar question about punctuation because the two are related, I think. Is it something to do with spatial-visual styles of learning and all that jazz? I was a very good speller as a child - I was also very good at maths. I have a brilliant sense of direction (if I say so myself). I'm the sort of person who can arrive in a foreign city, glance at a map and find my way around immediately. The sort of person who automatically looks at the sun to work out where I stand. (The eeriest moment on my first foray into the northern hemisphere was the first time I realised that the sun wasn't in the northern sky.) For me, all of that is connected, but I guess it ain't necessarily so.
I live with someone who can barely read a map (which makes for lots of friction on car journeys) and has a terrible sense of direction. She's a pretty good speller and punctuater but has a typical girl's anxiety about numbers.
I think Olle is going to be a good speller. He seems to understand the basic rules, in so far as English has rules. And from early on he seemed to know where he was placed - he'd point out landmarks as we drove past them. He can lead us to a destination he's only been to once before.
But one of the big struggles he and I had when he was younger was over jigsaw puzzles. I'd read that other kids his age (eg three) were able to do simple jigsaws so I expected him to be able to. He couldn't. He just didn't seem to get it. I'd get very exasperated. I knew this was not a good thing but when did knowing anything stop people from behaving badly. It frustrated me that he didn't seem to be able to piece a picture together. It also made me feel as if I'd done something wrong, somewhere along the line. (I spent a lot of time until he was about four feeling like I'd done something wrong. This was nothing to do with him and everything to do with me, as is probably evident.)
What have jigsaw puzzles got to do with spelling or punctuation? Possibly nothing. Or maybe it's that they are both a kind of visual scaffolding.
Of course, I now have a child who can stare at a Where's Wally picture for hours. And do a highly complex Where's Wally jigsaw puzzle. He can build Lego creations with barely a glance at the instructions even though he didn't make blocks into a tower until he was well over three (the books all said he'd be doing this when he was one. He didn't.)
Maybe spelling and punctuation are more a function of attitude than supposed brain type. Maybe it's got nothing to do with memory or visuals and everything to do with method, perfectionism, aesthetics, attention to detail or some combination of these.
