Over time, my wife and I would notice a change in him. He would become somewhat defiant when we would tell him that he needed to be done watching about /playing video games. He wasn't super pleasant to be around. It was a struggle to get him to take on chores or jobs around the house.
We started to take away the privilege of using his technology. What a change! He became more pleasant and compliant. The change was remarkable.
I am wondering if there is any research out there showing what happens to the brain of a child while playing video games vs using the iPad for academics. I guess I have another thing to look into.
