I have heard and read that mathematically gifted kids- boys, as far as I have discovered- reach their peak IQ at around 10.
What's the source of this (and what does it mean)?
I read it online in random scholarly articles (don't have the sources on hand, but you can google it), and I have heard this from a few parents, who had their sons tested, then retested a few years later to find a big jump in the VCI and a mild jump in the PRI. They tended to have first tested around six or seven, then again at 10 or 11.
I don't know why, but it seems like, in a verbally gifted world, that the mathy kids don't become "noticeable" until their verbal ability levels up. When I was looking up info about mathematicians, one thing I also noticed was a lot of them didn't become "gifted" until 10.
That makes sense. I do think mathy kids that (younger) age get short changed by the WISC IV compared to their math scores.
