Interesting. DS3.11 also demonstrates strong decoding capability, without same level of comprehension. He's an early reader too (2.7y). Within the last few months he's picked out more emotionally complex reactions from characters in both books and movies. I'm sure his emotional maturation is related to development of comprehension. He's also started reading in his head. Don't know where this fits in but he seems tickled by it.
Good point Portia about asking for a description - I've been guilty of asking for same. I'm always surprised that a kid who can detail every sandwich eaten, shirt worn and activity and partnership from a day at school isn't able to consistently describe. Thanks for the reminder!
Thanks for the NWEA site reference and plus Indigo. I'm interested to check it out.
