Wow judging by the amount of intolerance and pedantic annoyance in this and you previous replies I'm guessing you must be really smart and the fact that you must interact with us mere mortals must just eat you up.[/vent]
I for one thing would have liked to see whether the results observed in the group that received the games console were seen also in the control group after they received their consoles. That would certainly seem to have been completely feasible. Also it would be interesting to see if the test scores improved over time because as we all know when you have an awesome new toy you want to play with it all the time but interest wanes as time passes.
Something tells me that a few decades ago the introduction of a baseball kit or a new bicycle would have produced much the same effect.
ps: Mister Dvorkin, please don't eviscerate me again with your clever, clever wit.
