The IQ test DD took didn't have a speed measure, but there is no doubt in my mind that she would get a high processing speed score on one that did. Like your son, she is very fast (not always true with writing assignments--that's the exception) and very obviously "quick." This does sometimes mean she is sloppy. She tends to skim directions and to not always see every problem on a page because she's flying through the work. I made up a dorky little song to the tune of Row, Row, Row Your Boat, except it's "Check, Check, Check Your Work, Always Check Your Work!"
