I'm not a psychologist, but I did stay at a Holiday Inn last night. Psychology is not an exact science. From the few classes I have taken, I understand that we (people) know very little how our environment truly impacts human development. You can't point the finger at videogames without pointing it at all other forms of media. Also how much can you blame outside stimulus when the individuals mind may already be defective to start with. I think you (not literally you) could play the blame game all day but never really know the true cause. Ssssoooooo yes and no. For a healthy person I would say no, for someone who has a preexisting condition maybe, but maybe not. Its like a circle!!! Not like a square!!!
