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.

ZippyDSMleeI mean 4 main classes and maybe 3 or 4 model’s each…I’am just not seeing it….03/06/2015 - 8:28pm
ZippyDSMleeLame excuse is rather lame. Lets face it these days there there only a couple games that rely on such mechanics and it stifles player creativity to choose a body type for themselves and excludes those that wish to play as something closer to themselves.03/06/2015 - 8:17pm
Andrew EisenDoesn't matter if you play more games where the cast is the same basic character model. In this type of game, being able to easily tell which character you're looking at serves an important purpose.03/06/2015 - 7:29pm
ZippyDSMleeMechaCrash:Meh I've played more stuff that had pickups rather than set class's.03/06/2015 - 7:22pm
MechaCrashZarya's body type also has a pragmatic reason. Ever notice how in TF2, you can immediately tell who's who because they all have very different profiles? Same deal with Overwatch. If you see Zarya, you KNOW it's Zarya.03/06/2015 - 6:32pm

ZippyDSMleeNearly anyway the new UT game has color at least. And wow they changed to C++ 0-o03/06/2015 - 5:43pm
ZippyDSMleeCraig R.: Same reason why UT99/04 and UT3 are diffrent, gritty is the thing to do...at least it was... nearly everyone else grew out of dark and gritty….03/06/2015 - 5:40pm
ZippyDSMleeI doubt each model of characters in COH/COV/CO,ect are kept as unique model data.03/06/2015 - 5:39pm
ZippyDSMleemodel shape.03/06/2015 - 5:38pm
ZippyDSMleeMonte:I think it’s more a part of the engine, yes its more work but you should be able to have some sort of physical collision system in place to keep arms and stuff from clipping. Outside of that the data stored is just number variables to change the m03/06/2015 - 5:38pm
Andrew EisenAt least she's smiling in one of the pics.03/06/2015 - 5:31pm
Craig R.It's like somebody took the color palette and decided that anything approaching 'bright' is unacceptable03/06/2015 - 5:30pm
Craig R.Scratching my head as to why DC shows are as dark and drab, color-wise, as the movies look to be03/06/2015 - 5:30pm
MonteIf for instance you make the character fat, you need to make sure the animation of the character moving his arms and gun around, won't result in them clipping into the character's larger stomach03/06/2015 - 5:22pm
Monte@zippy, I imagine creating customizabel, vastly different body types would add a lot more complexity. Like making sure the character's animation still looks right. It can be done, but it can get complicated03/06/2015 - 5:19pm

prh99I think it probably far easier to add a character than strip a feature from game engine that was baked in from the start.03/06/2015 - 4:45pm
Andrew EisenAs I've said twice already, yes, strides in one area do not absolve anyone from criticism over where else they're falling short.03/06/2015 - 3:04pm
ZippyDSMleeI know I know one thing is not the other. Still worth nagging about.I still do not see why they do not put in body sliders and elt people make thier own body types....I'd do fat/pudgy or chibi befor I do ultra generic prefect body......03/06/2015 - 2:59pm
