I can understand the psychologist's reasoning with the PSP, or any other portable console, but maybe he is a little behind on the times.
How about giving them an XBOX360 or a PS3 with a sizeable collection of multiplayer only games? I mean, they already are over there standing, or sitting, in front of a tv, relaxing and doing absolutely jack but watching appropriately handpicked movies. How about giving them games where they can compete, cooperate, and bond with each other?
How about them playing FPS's on system link, or sports games, or racing games, or building crazy shit in Little Big Planet? If they could send them tv's they could have sent them consoles, right? Videogames can be an engaging, social experience.
I'm not negatively criticizing the decision since videogames aren't a need, at all, just merely pointing out that they could've served a useful purpose given the situation.
Anyways, they'll be allright.
