"5. It's proven that aggression levels change while playing violent video games. Do you think this change is permanent?"
False, from what I've read. Aggression levels are higher while playing, surely, but if anything people of all ages (16-60) are more calm while not playing, if they regularly play video games for at least a couple of hours a week.
I'm well aware, my secondary research is just facts facts facts from research that's already been approved. It was hard to devise a primary research to gather facts so, after asking my teacher, it's come down more to what the public opinion and knowledge is rather than the actual facts.
Aggression levels do rise while playing, and after playing there's a 3-4 minute cooldown slot but after that they're back to normal. Well, some research says. There's a LOT of contradiction in the current research, but this specific one is much more plausible and has more reliable results than "once you play, you're angry forever."
