there are some fun games and fantasy games like Myst, one of the highest-selling games in the industry, which invite kids into a world that requires them to solve a mystery or accomplish a goal. There are many others that require little more than quick, aggressive, violent responses to a perceived threat. These games reward kids for their speed in reacting and for their quick reflexes. The reactive portions of their brains are strengthened. The abilities to reflect and respond are not reinforced; in fact, they are stifled.
