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.

InfophileSomething weird was going on with that comment. As soon as I posted it, it looked like it had replies from the past. And now I can't even find it. Ah well, it was getting off-topic for that thread anyway.10/01/2014 - 4:29am
Sleaker@CraigR been using Win8.1 for a while, I don't really see any usability difference between it and 7 (Work uses 7)10/01/2014 - 2:16am
Craig R.Ok, my internal debate was short-lived. If Win10 is still a year out, I'm not waiting that long for an SSD, so on Win7 I will remain.09/30/2014 - 7:52pm
Matthew Wilsonits called windows 10, and I am happy to get the start menu back.09/30/2014 - 7:18pm
Jessy HartIs this stuff about Windows 10 legit? Is it actually called Windows 10 or is it just some stupid joke?09/30/2014 - 6:57pm
ZippyDSMleeSo I been trying to play Bioshock Infinite I got all the DLC,ect but do not want the extras to make your charatcer over powered from the start.....they force you to take them which is quite annoying......09/30/2014 - 6:45pm
Craig R.I need to upgrade to an SSD, still seriously debating moving to Win8.1 from 7 at the same time09/30/2014 - 6:07pm
Craig R.Win10 is probably Win8.1 with more cleanup and the Start button back.09/30/2014 - 6:06pm
Sora-ChanAhh, it's just weird seeing someone's post all of a sudden have replies from days prior before it was posted due to that.09/30/2014 - 5:49pm
MechaTama31sora: I broke the ordering intentionally, as AE's and my conversation had squeezed the text boxes down to be quite slim. I replied to an earlier post of his instead of the one I was actually replying to.09/30/2014 - 5:46pm
MechaTama31So, 9 would have been the good one, but they are skipping it to do two crap ones in a row?09/30/2014 - 5:41pm
Sora-ChanSo, judging from the poll post for #gamergate, it looks like too many thread replies breaks the ordering of posts, as seen with the recent post from Infophile.09/30/2014 - 5:31pm
Andrew EisenOr no! It wasn't Y3K compliant. Microsoft thought it best to super future proof its OS and skipped straight to 10 which is Y3K compliant!09/30/2014 - 5:01pm
Andrew EisenJust tell them it wasn't Y2K compliant.09/30/2014 - 5:00pm
Craig R.Looking forward to having to explain to coworkers down the road what ever happened to 9 *sigh*09/30/2014 - 4:57pm
Craig R.2k was crap. XP was solid, 7 is good, 8.1 is actually really good once you make it look like 7 :)09/30/2014 - 4:52pm
Sora-Chan@MP As someone who has used each version of windows since 3.1... I prefer Vista over 7 for various reasons. The only thing I give 7 over Vista is preformance. They really screwed up a bunch of things when making 7. Also, XP was a pain. 2k was better.09/30/2014 - 4:13pm
Jessy Hart@E. Zachary Knight Is that show called Pac-Man and the Ghostly Adventures?09/30/2014 - 3:34pm
IanCWin 8 isn't bad, it just can't decide whether to be a desktop OS or a tablet OS.09/30/2014 - 2:40pm
IanCI think its a way of getting round giving it free to Win 8 users...09/30/2014 - 2:39pm
