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.

MattsworknameAndrew and EZK help me pull back a bit , still working on it05/22/2015 - 7:06am
ConsterI think IP is the only person here who doesn't think IP needs to dial it back several levels.05/22/2015 - 6:14am

MattsworknameWell, on another subject, Saw this, and while I know it's fox news, thuoght I should share it05/22/2015 - 1:34am
MechaCrashYeah, even I think IP needs to dial it back.05/22/2015 - 12:35am

MattsworknameRE doc, everyone has a tendancy to let emotion get ahead of them, especially in an annoymous forum like the web. We have have those moments. Ip however has nothing but those moments. it's why I stopped responding to him, regardless of what he thinks or05/21/2015 - 11:17pm
DocMelonheadNo offense, but I see your behaviors in the comment sections uncalled for.05/21/2015 - 8:51pm
DocMelonheadHell, I could use both Goth_Skunk and IronPatriot as an example of such behavior between the two.05/21/2015 - 8:43pm
Andrew EisenMock? Ridicule? No, we're talking about serious threats and abuse, not people being cheeky or mean. Big difference.05/21/2015 - 8:42pm
DocMelonheadIn fact I see both mocks and ridicule between both the GamerGate Supporters and GamerGate Critics.05/21/2015 - 8:41pm
DocMelonheadAs for the Harassment, well, this is the internet; people will mock and ridicule whoever they want, whenever they want, at all times.05/21/2015 - 8:40pm
Mattsworknamegoth I think all media news outlets have that disclaimer05/21/2015 - 8:39pm
Andrew EisenThat's an... interesting way to interpret that.05/21/2015 - 8:36pm
Goth_SkunkAnd re BBC vs Rockstar: Ahh. I missed that. Woops!05/21/2015 - 8:33pm
Goth_SkunkAE: The entire disclaimer is a valid reason why I don't take it seriously. Particularly the part where they say "the information contained herein may not be necessarily accurate or current." Because fact-checking, like math, is haaaaaaaaard!05/21/2015 - 8:32pm
MattsworknameI take all media reporting with huge skepticism. the Mary sue Included. that said, there not as bad Jezebel.05/21/2015 - 8:27pm
