Is there a link between above average intelligence and quirks? Somewhere I vaguely remember reading about quirks and intelligence; My son just turned 6 and he has been exibiting peculiar mannerisms, i.e., he would wiggle his body in little quirky motions every couple of minutes. When given a "stop this or else..." he did. But now he wrinkles his nose like he needs to sneeze; he says he doesn't know why he does it; that it itches; used to wink his eyes; pull at his shirt. He is not hyperactive, he taught himself to read 1 year ago, now he is reading with great comprehension at the 5th grade level, he plays chess, does mutiplication, can spell better than his sister in 7th grade, computer literate, etc....
