Grinity, do you remember where you read about the cortical thickening delay? Very interesting.
I've heard this also. I recall reading something about it (can't remember where) and I also had an email discussion with someone at SENG who said that gifted kids are similar to ADHD kids in this regard (delayed meta cognition and cortex development... or something like that... I should pull up the email so I can quote it correctly). Anyway... she said that gifted kids shouldn't be tested before the age of 8 years because behaviours can get in the way of results.
