I've heard that the more extreame LOGs can be associated with 'a certian concreteness.'
This was certianly true of my DS, it got worse ages 10-13, and is delightfully improving by leaps and bounds now at 14.
I had the intuition that it was important to get my DS out of the house at age 13 because his 'black and white' thinking was allowing him to blame all his woes on 'mom and dad.' I wanted him to get into a bigger world where he was in a more responsibly position and had more of a sense of being free to determine his own fate. And I wanted the structure and support of a 'snoopy' boarding school.
I don't know if my intuition was correct, but DS14 is much more self-reflective, and 'full color' in his outlook after 4 months of school.
Yippee!
