In good and bad, depending on quantities and opposite input: your thinking becomes what you put into your brain. the eudcation you get from only reading comics does not compare to the one you get from going to university and reading world literature. Some games may be able to train you let's say systemic thinking and understanding of networks and complex interrelations. Others may train your reflexes only, or your eye-hand-coordingation. Obviously, you need to look closer. You could call SH3/4 a historic game, but you won't get any relevant historic education from playing it, you won'T win the intelletcual ability to analyse the conflict and form an educated opinion about how it emerged, why, and what came as a consequencesfrom it after WW2. So, the educational value of SH3/4 nevertheless is almost nil.

To assume games do no effect cognitive functions and behavior in different ways, sometimes for the better, sometimes for the worse, is illogical.

But possible that the subject itself does not even get a clue on how it has changed in personality, and thus will reject the possibility alltogether. But the experts to assess that are not the effected individuals in this case, but the outside observers.
