Research: Predicting Video Game Skills Through Brain Imaging

January 14, 2011 -

New research from the University of Illinois unearths a technique that can predict "with unprecedented accuracy" how well a subject can perform on complex tasks simply by analyzing a certain part of the brain. University of Illinois Beckman Institute director Art Kramer and colleagues have developed a way to predict how well study subjects would do on a strategic video game using established brain imaging techniques.

Using magnetic resonance imaging and multivoxel pattern analysis, researchers found differences in patterns of a "particular type of MRI signal, called T2, in the basal ganglia of study subjects." Analyzing these differences enabled researchers to predict between 55 - 68 percent of the differences in performance among 34 subjects who later learned to play a game developed by the university.

"There are many, many studies, hundreds perhaps, in which psychometricians, people who do the quantitative analysis of learning, try to predict from SATs, GREs, MCATS or other tests how well you're going to succeed at something," said University of Illinois psychology professor and Beckman Institute director Art Kramer. But, he adds, never to this level of detail.

First subjects had their brains imaged, then spent 20 hours learning to play a game called Space Fortress. In the game players must destroy a fortress without losing their own ship to several different hazards and defenses. Subjects had little or no experience with video games prior to the study. The game was designed to test participants' real-world cognitive skills.

"We predict up to three times as much of the variance (in learning) as you would using performance measures," Kramer said. The researchers tested their results against other measures and replicated the findings in new trials with different study subjects.

"Our data suggest that some persistent physiological and or neuroanatomical difference is actually the predictor of learning," Kramer said.

Kramer cautions that these findings should not be interpreted to mean that some people are destined to succeed or fail at a given task or learning challenge, adding that "many of these components of brain structure and function are changeable," he said.

Craig R.tldr: I'm a gamer, and imo those who support GamerGate should feel free to take a flying leap off a cliff.09/20/2014 - 1:27pm
Craig R.Not only that, I'm pretty sure that if actual studies were done, you'd still deny them, Sleaker. After all, it's not what you'd want to hear to support your rose-colored view of GamerGate.09/20/2014 - 1:18pm
Craig R.There IS an issue. Nor do we need a study to show that if you deny it then you're part of the problem.09/20/2014 - 1:17pm
Sleakersimply oust people that do harass others.09/20/2014 - 11:34am
Sleaker@Conster - I can say the same thing if you think there's been more than a handful. Until there's an actual study on rates no one can claim to know how widespread the incidence of harassment is. Thus the best we can do is 'there might be an issue' and...09/20/2014 - 11:33am
ConsterSleaker: if you think there's only been "a handful of" incidents, you have your head stuck *somewhere* - I'm assuming it's sand.09/20/2014 - 5:38am

Andrew EisenWell this is unique! A musical critique of the Factual Feminist's "Are Video Games Sexist?" video. https://www.youtube.com/watch?v=-K4s7cV4Us409/20/2014 - 2:41am
Andrew EisenSome locked threads. Some let them be. So, no, I'm not seeing a problem here. No corruption. No collusion. No ethical problem with privately discussing ethics.09/20/2014 - 12:48am
Andrew EisenAnd still, in the end, Tito made up his own mind on how to handle his site. All 150 or so members went off to handle their own sites in their own ways. Some talked about it. Some didn't. Some changed disclosure policies. Some didn't.09/20/2014 - 12:40am
Andrew EisenThere were two comments other than Kochera and Tito's. One pointed out the Escapist Code of Conduct, another comment was in support of Tito.09/20/2014 - 12:40am
Andrew EisenKochera privately expressed his disagreement on how Tito decided to do something. No, I don't consider that crossing a line nor do I consider the exchange an example of the group pressuring him.09/20/2014 - 12:36am
Kronotechnical reasons. Anyways, I need to get to sleep as well.09/20/2014 - 12:29am
KronoAnd he wasn't the only one pushing Tito to censor the thread. If Tito had bowed to peer pressure, we likely wouldn't have gotten this http://goo.gl/vKiYtR which grew out of that thread. Said thread also lasted until a new one needed to be made for09/20/2014 - 12:28am
Krono@Andrew So it's an example of Kuchera crossing the line from reporter to advocate. And an example of the group pressuring for censorship.09/20/2014 - 12:21am
E. Zachary KnightAnyway, I am off to bed. I will probably wake up to all of this being knocked off the shout box.09/20/2014 - 12:20am
E. Zachary KnightKrono, that is the type of reading too much into things that bugs me. Ben did no such thing. Greg had the last word in that part of the exchange. The rest was about how to approach the story and Quinn.09/20/2014 - 12:19am
Andrew EisenSo?09/20/2014 - 12:13am
KronoExcept that the forum thread wasn't harassment, and Kuchera continued to push for the thread's removal after Tito made it clear he didn't consider it harassment.09/20/2014 - 12:12am
