Playing Medal of Honor and Need for Speed yield differing effects on brain

A new study has found that adolescents who play violent video games may exhibit lingering effects on brain function, including increased activity in the region of the brain that governs emotional arousal and decreased activity in the brain's executive function, which is associated with control, focus and concentration. The findings were presented earlier this week at the annual meeting of the Radiological Society of North America (RSNA).

 

"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," said Vincent P. Mathews, M.D., professor of radiology at Indiana University School of Medicine in Indianapolis. Co-authors to the study are Yang Wang, M.D., Andrew J. Kalnin, M.D., Kristine M. Mosier, D.M.D., Ph.D., David W. Dunn, M.D., and William G. Kronenberger, Ph.D.

 

Dr. Mathews and colleagues randomly assigned 44 adolescents to play either a violent video game (Medal of Honor: Frontline) or a nonviolent video game (Need for Speed: Underground) for 30 minutes. The researchers then used functional magnetic resonance imaging (fMRI) to study brain function during a series of tasks measuring inhibition and concentration. One test used emotional stimuli and one did not.

 

fMRI measures the tiny metabolic changes that occur when a part of the brain is active. These changes will appear as a brightly colored area on the MR image, indicating the part of the brain that is being used to process the task. The two groups did not differ in accuracy or reaction time for the tasks, but analysis of the fMRI data showed differences in brain activation.

 

Compared with the group that played the nonviolent game, the group that played the violent video game demonstrated less activation in the prefrontal portions of the brain, which are involved in inhibition, concentration and self-control, and more activation in the amygdala, which is involved in emotional arousal.

 

"During tasks requiring concentration and processing of emotional stimuli, the adolescents who had played the violent video game showed distinct differences in brain activation than the adolescents who played an equally exciting and fun – but nonviolent – game," Dr. Mathews said. "Because of random assignment, the most likely factor accounting for these differences would be the group to which the volunteers were assigned."

 

The researchers hope to conduct additional research on long-term effects of violent video game exposure and the impact of these brain functioning differences.

 

"Additional investigation of the reasons for and effects of this difference in brain functioning will be important targets for future study, but the current study showed that a difference between the groups does exist," Dr. Mathews said.

Violence only difference?

So, have they really proved that violence in games affect the brain, or just that Need for Speed and Medal of Honor affect the brain in different ways?

The reasearch does not say that there can not be an effect from violent games, but also not that there is one unless they are able to rule out all other differences between the games as the cause for the differing results.

There is usually a significant difference in pace in racing games and FPS games that even if both are "exciting" could easily affect how you use your brain in order to play the two. The tasks you perform are only very shallowly similar in the two games.

An FPS game tends to be much more "reactive" than a racing game. You constantly scan the environment for threats and react to them as they appear. A racing game is all about learning the track and to keep the perfect line. About repeating the same pattern down to perfection.

This kind of research does not sound very scientific to me. It's just intended to "prove" a point.

If they really wanted to make this comparison right they could just have made two mods of the same game. One which includes violence and one where you shot water or something. This comparison shows they don't understand games. FPS is all about being alert and always wondering who will pop out where. Many people including me get a sense of being "scared" when an enemy jumps out. but its not really that I am scared its more of a way of trying to react really fast to unexpected events. Driving games are not like that. they are much more about getting in the flow and if you are good you can do it without much attention eg "I know this course and this car so I basically know what to do and what will happen"

Interesting study, to bad they didn't ask a gamer first of what to compare.

There are different types of "Violent" video games. Grand Teft Auto is a much different game than Medal of Honor. There are also different types of "non-violent" games like Need for Speed and NBA 2k7. I want to also see some satistics on this experiment not a picture of one persons brain activity.

I think this project is just being used to sterotype all "Violent" video games are bad for you.

I have to agree that they are stereotyping that all violent games are bad for you. Frankly, I will say it again, I play imported Japanese games where rape and torture are main themes, and I am not doing them in real life.

Time to realize that the real issue behind violence in society is children being beaten by their parents and other children in schools and at home.

The conclusion was:
the group that played the violent video game demonstrated less activation in the prefrontal portions of the brain, which are involved in inhibition, concentration and self-control, and more activation in the amygdala, which is involved in emotional arousal.

So what are you saying? having emotion is bad now? and inhibition is always good?
You might just as well conclude that this study says non-violent games are emotionally stifling and should be discouraged, also they aren't worth their money for they create no emotional response.

I don't see anywhere where the researchers make a moral judjement on either. This is research that is very interesting research. You could possibly find some similarities between the brain activity during certain types of games and their real-life counterpart activities. That would be the holy grail of the future of "realistic" games. How can we get your brain to react just like in real life? A lot of potential...

While I agree there is a difference in the two styles of games, I would like to point out that there is a similar learning curve to FPS maps in multiplayer. Good players learn the maps and where the enemy is most likely to appear and at which time, best defensive/offensive locations, etc.

I agree. This has the smell of bullshit.

Where's the constant. Aka the group of People who play neither?
Any one in any sort of science field would immediately see the problem with this type of test. It yields results, but the question still remains, what are those results, what do they mean, and how did they derive them.

No shit, that a game alters your state of mind. Driving for pete sake, alters your state of mind. Everything has an effect on it. And so, how do we know that the other gamers weren't effected in any way shape or form by the "non-violent" games.

I'd like to see a little more research and evidence before I made any conclusions on the effects of Violence in Videogames has.

Going off on what you said... while playing a FPS game, most tend to try to startle the user or simply being injected into a fast-paced situation. These require the fight-or-flight thinking that the doctors noticed that the CoD players showed after playing. Now, these reactions aren't necessarily caused by violence... they're caused by a sudden situation in which failure is imminent unless proper actions are taken. FPS games can take it to a higher level with sound effects such as bullets or rockets or whatever it might be.

Essentially, the adrenaline released during such a stimuli don't just magically disappear. It will still exist in your system for a little bit and that's what these doctor's observed.

That was exactly my point.

Did the differences really stem from the violence, or other differences.

I am pretty sure you could create a non-violent game that induces the same kind of fight-or-flight syndrome.

It's pretty easy to compare apples and oranges and come to the conclusion that they are different.

So...Medal of Honour is "violent"...based on ESRB I guess. Maybe they should compare Grand Theft Auto: San Andreas and Winning Eleven 8. I think they would have the results turn the other way around. Meaning the "violent" GTA:SA will not have as much effect as WE8 since WE8 needs more response and reaction from the players.

Yeah, we can do our own study too. We named it "Violent games are not as brain damaging as non-violent ones" whereby we kill people in The Sims 2 (Violent) and then, we play FIFA World Cup 2006 (non-violent). There, our "scientific" conclusion based on our "selective" test scenarios.

P.S. Playing Dark Messiah doesn't make me want to kill people with a sword/dagger/staff/a random object and see everything bloody, THAT i want to do in a GAME and actually, seeing blood in real-life makes me a bit sick.

Sure the prefrontal regions are less active in an FPS: the whole point of an FPS is to quickly and simultaneously identify and eliminate a threat which is why the amygdala is more activated (as expected with threat ID)

And of course the prefrontal regions are more active in a driving sim: you don't just "react" - you have to make judgment calls and interpret stimuli in a more detailed fashion to corner properly - in an FPS you don't have time to process - fire first, ask questions later!

The research seems to be perfectly valid at first glance, but does not detail if there are lingering effects and certainly doesn't imply that violent games are bad. More media spin on this.

I have to say this article has some of the best comments I've ever read.

I think that everyone will agree that all this study managed to prove was that it takes less "brain power" to play a racing game than a FPS. Anyone who has ever played one of the endurance races on Gran Tursimo will agree with me on this one. After about lap 10 you're not even thinking anymore. You've learned what buttons to push when, and the brain goes on auto-pilot. If you can find the person who plays a FPS like that, they are either a god, or just a free kill.

All this study shows is exactly what those who funded the study wanted it to show.

Might there be a correllation between violent behavior and excessive video gaming? Possibly...even probably.

But, that doesn't explain causation at all. Which spurred which? Does the individual play violent video games as an outlet for pent up aggression or is the aggression a result of video gaming? This study, and all others like it, address neither.

We can go on and on about how different stimuli affect the brain and draw all kinds of irrelevant conclusions. I'd venture to say that golfers suffer the same kind of rage when they miss a birdie putt as a thirteen year-old boy suffers when he misses a head-shot in Counterstrike and is instead gunned down. Does that mean that golfing is inherently bad because it excites players to anger?

If we believe what these scientists say, then the answer must be yes.

The extent of this study is too small and too narrow minded to draw any conclusions from, but there is some truth to it.

They should factor in that people play these games about 8h straight on, and the also games like Medal Honor isn't that violent compared to other games. The study says "shoort-term" effects as well, which doesn't bother me that much either.

I myself find little satisfaction in these types of games, but one every now and then it's fun to blow things up! Keep at it, but do otherthings as well, that's my tip.

As a gamer reading this article, it is clear to me that they want to show a bad reaction to violent video games.

Why not test something that is viewed daily by much more of the population- movies and TV. I'm sure if they tested 1000 people who watched Bambi and the Terminator, that the Terminator crowd would show results that the movie industry would try to squelch or discredit.

In my opinion violent TV and movies are a much bigger threat to people then violent video games. Maybe it is possible that a format (games) that has only been around 20 years or so is the cause of so much violence in the world, but more likely it is something that most people see everyday (movies and TV).

(I don't expunge to try to avoid 'that' political discussion)
For me this sort of disproves the direct 1:1 effects of TV people.

Look, they said temporary first of all. Second, fMRI is basically telling you what areas of the brain are more metabolically active - different parts of your limbic system (part of the brain involved with emotion) *should* be more or less active based on the way something makes you feel. The same goes for performing different tasks; if the driving game is operated via a steering wheel and pedals, but the FPS is mouse and keyboard, you'd expect to see different motor neuron activity in the prefrontal gyrus. It's just cool that we can map this stuff with technology.

Totally.

Driving involves some degree of control and precision, fragging stuff is probably less about control and more about reactions and strategic thinking, maybe emotional response is a byproduct of that type of game.

I'm a total layman, but intuitively I'd say the differnce has more to do with the way the brain is required to parse data than necessarily the method of input / output. You know right away that it "feels" different to be playing these games, these guys are just trying to find some scientific way of framing that.

Don't you guys see it? What you're saying is exactly the point.

I myself am a gamer, I have been for years. I even specifically played Medal of Honor for about 4 years. However, I stopped about six months ago. Therefore, I'm not biased in any way. Been there, done that.

You chaps are saying that FPS games are about scanning and reaction, while racing games are about memorizing the environment and staying on course with it, and that naturally the brain waves are going to be different.

Well that's exactly the point. FPS games teach a person to emotionally scan and react to a situation. Thereby, the our brains learn to not focus. We looks at one base entrance, and another, and another, and look for vehicles, etc. We are not focused or concentrated on one goal. It's about reaction.

On the other hand, a racing game would teach a person to memorize the course of life, and stay on track with it. They know that taking a left turn means taking a left turn, and when it comes again, they know what to do. They stay on the road and focus on not crashing. There's great concentration and one-thought proccessing in a game like NFS.

Now I'm not saying that if someone taps a FPS player on the shoulder they whip out their glock and headshot him, I'm saying that's the way the brain will react on a much more minor scale. As someone way above me said, things that happen to the brain don't disappear, they leave a slight trace, and build.

Thereby, I see this research subject as a start. Not definative in any way. It's really quite a poor job, but there's nothing wrong with it, and as you can see, they don't claim on any details. Quit defending games just because you play them.

If you think this research is bull, then examine your reaction, those who named it so.

You saw it as a threat to you and what you do, so without further research yourself, you simply denounced it as true. Tell me if that doesn't mirror how one plays a FPS.

I think it's fair to say that different activities, even different types of computer games, have an effect on the *pattern* of activity within the brain and this study shows it conclusively.

However, it could be read, that it seems to imply that FPS games produce loss of control, and induce an emotional rather than rational reaction. Our ids and egos rearing their ugly heads. So far so negative.

What it does *not* address, is that maybe it is necessary and healthy for humans to have periods of emotional 'outlet' or a relatively controlled 'loss-of-emotional-control'. Maybe violent FPS players stop their games and are more likely to chill out afterwards. Maybe people who don't play violent FPS games are more likely to argue and beat their wives/kids. I'm not saying there's enough evidence either way, I'm just saying maybe. I can tell you for certain that it's too insubstantial to draw conclusions or pass laws based on the study.

It is an embarrassment to science that people are doing such sloppy work. No wonder the public distrusts scientific research; you can always find somebody to slap together a study purporting to prove whatever premise they want proven.

How about a study that shows the effect on test results of research grants from different entities?

Constantly being in a violent environment, and playing a violent video game are very different things. If your a soldier at war you are witnessing real life violence and are unable to get away from it. With a video game it's fake. When I kill someone in CS I know I didn't actually kill them, I just beat them at the game. And when I'm done playing I may remove myself to an environment of my choosing. And by the way what are your sources for the negative impacts these games have on MOST poeple.
