This sort of ability likely can be improved with the right sort of practice exercises...so not so big a deal.
Anyhoo, if this and a slightly increased ability to deal with math are the big differences I’d say that the girls wondrous ability to give birth more than balances the scales :-)
I have always had strong visual imagery skills. I can easily see 3d images of objects and rotate them about. While seeing such imaginary images the visual field can blank out for just a couple of seconds... I think many people do this, it is a bit worrying while driving and so I have to concentrate strongly on the road and not daydream for if I do eyesight blanks out...not good.
I have always been in awe of people with photographic memories, I have a very limited form of it that allows me to generally see the location on the printed page where a specific statement is located... I always skim through books looking quickly only at that spot on the left or right page till I find the info.
But I have an infuriating lack of talent for spelling things aloud, the only way I can do it is to see the word as text suspended in the air and then simply read the letters out one by one. A very roundabout way of doing something so simple.
Picture a red apple.
Turn it around 1/2 way, and then turn it upside down.
All that happens in "a mind's eye"
I agree most can do spatial thinking if they are trained to it.
Your post describes my thinking and abilities....and I know what you mean about not daydreaming while driving.
Let me guess, your grade one report card complained about the amount of time you spend daydreaming too, right?
