Do any of you know Davidson's rationale for using the FSIQ rather than the GAI on Wechsler tests? It seems a little inconsistent of them.

I understand that they have to have some sort of cutoff. I think it would be good, though, if they explained their logic.

Also, the lower age limit used to be 4. Why not offer support to families when their children are 4 and are starting school? This tends to be a very difficult time for people.
