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.

Andrew EisenIf you do, I hope you can provide some examples of people (again, other than random no-name numbnuts on Twitter) who are genuinely trying to dictate what should and should not be allowed so far as themes, topics, language, plot devices, etc. go.07/01/2015 - 9:43am
MattsworknameI'd go into why I think it's a bigger problem then most realize, but nows not the time really. I'll catch up with everyone later07/01/2015 - 9:42am
Andrew EisenThat's the thing though, rarely is anyone (again, other than random numbnuts on Twitter) attempting to dictate what can and cannot be said or done.07/01/2015 - 9:39am
Andrew Eisen"Don't write rape scenes" is being offered as advice (along with reasons for that advice) not a mandate.07/01/2015 - 9:37am
MattsworknameOh, on that last one andrew I wasn't talking about the article, I was being more general, lately it seems like all the news and media is trying to decide what is and isn't proper to say. Thats what i was refering to.07/01/2015 - 9:37am
Andrew EisenPerhaps you should consider reading the entire article. Despite quotes you can pull from the intro and conclusion, the author isn't arguing that you can't or shouldn't be allowed to cover a certain topic.07/01/2015 - 9:35am
MattsworknameOne of the things I hate right now is that people are trying to be the deciders of what is and isn't proper to be said. It's political correctness to a level that makes me angry.07/01/2015 - 9:29am
Mattsworknamemake them, i just tell peopel that I think what they did sucked. Just cause I dont like what they did, doesn't mean I can tell them "You shouldn't wrtie that" cause thats just another step on the way to telling them "YOU CANT WRITE THAT".07/01/2015 - 9:24am
MattsworknameNo, but you or I aren't the one to tell someone else what they can or cannot do beyond EXTREMELY narrow limits. Telling a person then shouldn't write something or say something. I may hate certain movies or music, doesn't mean I dont' tell peopel not to07/01/2015 - 9:23am

TechnogeekImagine that level of accuracy, only applied to something that has actually caused physiological and psychological trauma in more cases than just whatever the equivalent of the CD-i Zelda games would be.07/01/2015 - 8:40am
TechnogeekThat's the issue I see as well, E. To put it in terms anyone reading this site will likely understand: you know how any time video games show up on TV, they feature absurdly outdated 3D graphics and/or audio from the Intellivison era?07/01/2015 - 8:40am
InfophileWell, you CAN go to a crowded streetcorner and tell everyone who passes by your social security number and bank account PIN, but you shouldn't. Is that censorship?07/01/2015 - 8:36am
E. Zachary KnightSo if it is going to turn out to be a bad scene, why even bother writing it?07/01/2015 - 8:07am
E. Zachary KnightMatts, Goth, The article, and others I have read making the same conclusion, state that most people fail in their attempts to write rape scenes without being overly offensive or overly incompetent in their attempt.07/01/2015 - 8:07am

InfophileIn other words, you stopped when you found out it was arguing for a position you disagreed with, but before you found out why.07/01/2015 - 5:29am
Goth_Skunk"In short, anyone can write a rape scene—but should they? Chances are, the answer is no." And that's where I stopped reading.07/01/2015 - 5:11am
