Research Compares Teenagers Who Frequently Game to Gamblers

November 17, 2011 -

Researchers at the Charité University Clinic for Psychiatry and Psychotherapy in Berlin, Germany, found that gamers who play "frequently" have greater left striatal gray matter volume compared with those that are considered to be moderate gamers. Researchers say that these findings show the importance of "striatal volume and activity in shaping preference of skills for video gaming."

"The key finding of higher volume in left ventral striatum associated with frequent video game playing is in conceptual accordance with findings of enhanced dopamine release during [this activity] and excessive gambling in Parkinson's patients [given] dopaminergic medication," the investigators write.

Researchers were led by Simone Kühn, PhD, from the Faculty of Psychology and Educational Sciences, Department of Experimental Psychology, Ghent Institute for Functional and Metabolic Imaging, Ghent University, Ghent, Belgium; Charité University Medicine; and Physikalisch-Technische Bundesanstalt, Berlin and Braunschweig, Germany. They analyzed MRI scans of 154 14-year-olds from the IMAGEN project, a European multicenter genetic neuroimaging study in teenagers.

Participants were divided into groups, based on a median of 9 hours weekly spent playing video games into 2 playing categories: frequent (76 total - 24 girls, 52 boys) and moderate (78 total - 58 girls, 20 boys).

Researchers found that the frequent gamer group had a significantly increased volume of left grey striatal matter compared with moderate gamers, which in turn was associated with higher functional MRI activity when not winning in a gambling task. The increased activity was negatively correlated with deliberation time in betting, as evaluated using a Monetary Incentive Delay task used to assess brain activity during reward anticipation and reward feedback.

"Individuals with higher ventral striatum volume might experience video gaming as more rewarding in the first place. This in turn could facilitate skill acquisition and lead to further reward from playing," the authors write. "If the striatal differences observed in the current study are indeed an effect of gaming, video gaming might pose an interesting option to explore structural changes in addiction in future studies."

The IMAGEN study receives research funding from the European Community's Sixth Framework Program and is supported by the UK Department of Health National Institute for Health Research–Biomedical Research Center 'Mental Health' and a MRC program grant. Additional funding was provided by the Berliner Senatsverwaltung. The study was published online November 15 in Translational Psychiatry.

I like how this research doesn't use vague test measures but actual MRI-results. And more importantly, they admit they don't know which of the two is the cause.

Is King right? Should all games adopt the free-to-play model?:

MaskedPixelanteNumber 3: Night Dive was brought to the attention of the public by a massive game recovery, and yet most of their released catalogue consists of games that other people did the hard work of getting re-released.04/17/2014 - 8:46pm
MaskedPixelanteNumber 2: If Humongous Entertainment wanted their stuff on Steam, why didn't they talk to their parent company, which does have a number of games published on Steam?04/17/2014 - 8:45pm
MaskedPixelanteNumber 1: When Night Dive spent the better part of a year teasing the return of true classics, having their big content dump be edutainment is kind of a kick in the stomach.04/17/2014 - 8:44pm
Matthew Wilsonhttp://www.giantbomb.com/articles/jeff-gerstmann-heads-to-new-york-takes-questions/1100-4900/ He talks about the future games press and the games industry. It is worth your time even though it is a bit long, and stay for the QA. There are some good QA04/17/2014 - 5:28pm
IanCErm so they shouldn't sell edutainment at all? Why?04/17/2014 - 4:42pm
MaskedPixelanteNot that linkable, go onto Steam and there's stuff like Pajama Sam on the front-page, courtesy of Night Dive.04/17/2014 - 4:13pm
Andrew EisenOkay, again, please, please, PLEASE get in a habit of linking to whatever you're talking about.04/17/2014 - 4:05pm
MaskedPixelanteAnother round of Night Dive teasing and promising turns out to be stupid edutainment games. Thanks for wasting all our time, guys. See you never.04/17/2014 - 3:44pm
Matthew WilsonAgain the consequences were not only foreseeable, but very likely. anyone who understood supply demand curvs knew that was going to happen. SF has been a econ/trade hub for the last hundred years.04/17/2014 - 2:45pm
Andrew EisenMixedPixelante - Would you like to expand on that?04/17/2014 - 2:43pm
MaskedPixelanteWell, I am officially done with Night Dive Studios. Unless they can bring something worthwhile back, I'm never buying another game from them.04/17/2014 - 2:29pm

NeenekoAh yes, because by building something nice they were just asking for people to come push them out. Consequences are protested all the time when other people are implementing them.04/17/2014 - 2:06pm
Matthew Wilsonok than they should not protest when the consequences of that choice occur.04/17/2014 - 1:06pm
NeenekoIf people want tall buildings, plenty of other cities with them. Part of freedom and markets is communities deciding what they do and do not want built in their collective space.04/17/2014 - 12:55pm
Sora-ChanI realize that they have ways getting around it, but one reason might be due to earthquakes.04/17/2014 - 4:42am
Matthew WilsonSF is a tech/ economic/ trade center it should be mostly tail building. this whole problem is because of the lack of tail buildings. How would having tail apartment buildings destroy SF? having tail buildings has not runed other cities around the US/world04/16/2014 - 10:51pm
Matthew WilsonAgain the issue is you can not build upwards anywhere in SF at the moment, and no you would not. You would bring prices to where they should have been before the market distortion. those prices are not economic or socially healthy.04/16/2014 - 10:46pm
ZippyDSMleeYou still wind up pushing people out of the non high rise aeras but tis least damage you can do all things considered.04/16/2014 - 10:26pm
ZippyDSMleeANd by mindlessly building upward you make it like every place else hurting property prices,ect,ect. You'll have to slowly segment the region into aeras where you will never build upward then alow some aeras to build upward.04/16/2014 - 10:25pm
