The IQ levels in Table 1 are interesting -- basically if you know nothing else about a kid other than they are reading before K, you should revise your estimate of their IQ from 100 to 130. I.e., there is big news in the fact that a kid is reading early.
I've always been of the opinion that it means nothing negative about a child's IQ if he/she is NOT reading early, but it probably means something positive is he/she IS. There did seem to be a bit in that article about kids w/o high IQs who were preocious readers, but not a lot (I skimmed). I have not met a child who was a self-taught, fluent reader before K who was NOT gifted, although I am told they are out there.
