Hey George. Does your sons lower PSI show itself in any practical ways? Is he particularly strong in any academic areas vs others?
I think high WMI allows him to ponder a whole lot of stuff in his head at once, and so he can be really thorough...
I have always said he seems to always have something going on in his head. I have had similar experiences, in that he takes his time to really consider his responses before answering a question (or sometimes responding to a directive). I'm not sure if it takes a while to travel from his ears to get to the point that he understands what needs to be done, or if he is just over analyzing!
I haven't experienced the math issue you described.
