"Our study suggests that playing a certain type of violent video game may have different short-term effects on brain function than playing a nonviolent, but exciting, game... What we showed is there is an increase in emotional arousal. The fight or flight response is activated after playing a violent video game," Mathews said.
No real surprise there, if you ask me.
Mathews said he hopes to conduct additional studies on the long-term effects on brain function of exposure to violent video games.
So what is CNN.com's headline on this story about (rather unsurprising) short-term effects, in which the researcher explicitly makes it clear that the results say nothing about long-term effects? Why, naturally, the headline summarizes the story thusly: "Study: Violent video game effects linger in brain"
Why, yes, that does seem to be precisely the opposite of what the study actually examined, thank you for asking.
