I tend to put my faith in what Reneer says. Mainly because he makes more than a little sense when it comes to these matters.
Well, that just made my day. ^.^
I think I'll ignore all the experts on addiction and psychology in this thread (i.e all of you, apparently) and say that the report was probably trying to say that playing over 2 hours of video games is a sign of possible addiction, it's not concrete evidence and should not be taken as such but it shouldn't be ignored either.
This.
Apparently I didn't think to make it clear earlier, but I'll that oversight here:
1. The report is not saying that 2+ hours of video-game / screen time a day means you are addicted, as Exorince pointed out.
2. The 2 hour limit per day was originally set by the AAP and was meant for kids, not advlts. You're all advlt.
3. This report is talking about addiction potential, and even then there isn't clear evidence.
4. The report itself even says that there is no clear evidence that video-game overuse should classify as an addiction (page 4):
However, as with findings on long-term aggression, there is currently insufficient research to definitively conclude that video game overuse is an addiction.
