It is interesting! My son was actually NOT a reader before kindergarten - but definitely the lego, maze, suduko dude. He actually hit the ceiling of the pattern matching part of the NNAT test. I remember walking down the street with him when he was younger and he would make patterns of the trees on the boulevard.

My son went from not being interested in reading on his own to reading at 4th to 6th grade level in about 9 months. Once he figured out he could read books like Captain Underpants on his own, he was totally into it. ;-) High quality literature, I know. I definitely think he is a Visual-Spatial learner. It's all or nothing with him.
