What? It’s not “poverty” that makes you dumb? Once again the data contradict Leftist nostrums. Many of the skills mentioned below are closely linked to IQ. Mental speed and brain size have long been known as correlated with IQ. So the research below confirms a lot in IQ research. Note the confirmation that IQ can’t be “trained”

HOW well you play a video game can be predicted by measuring the size of structures in your brain. Researchers have found certain brain centres play a vital role in influencing traits crucial to video game success. The findings could lead to applications for education and treatment of dementia.

The study, published in the scientific journal Cerebral Cortex, adds to evidence that a collection of distinctive tissues deep in the brain influence the ability to refine motor skills, learn, plan, and adapt quickly to a changing environment. “This is the first time that we’ve been able to take a real-world task like a video game and show that the size of specific brain regions is predictive of performance and learning rates,” said University of Pittsburgh psychology professor Kirk Erickson.

The study was done by Pittsburgh University, the Massachusetts Institute of Technology, the McGovern Institute for Brain Research, and the Beckman Institute for Advanced Science and Technology at the University of Illinois.

Researchers explored an anomaly between novice and veteran players. Research had shown expert players outperformed novices in areas such as attention and perception. But training novices for endless hours produced no measurable benefit to their cognitive abilities.

The study’s authors believed existing differences between individual brains might explain the anomaly. They concentrated on an area known as the striatum. “Our animal work has shown that the striatum is a kind of learning machine – it becomes active during habit formation and skill acquisition,” said McGovern Institute investigator Ann Graybiel. “So it made a lot of sense to explore whether the striatum might also be related to the ability to learn in humans.”

The researchers used high-resolution magnetic resonance imaging to analyse brain regions of 39 adults aged between 18-28 who’d spent less than three hours a week playing video games in the previous two years.

Half were asked to focus on maximising their score; the rest were asked to periodically shift priorities, improving skills in one area before moving to something else. Players who had a larger brain “reward centre” did better early on; players whose brain centres for motor skills and adaptation were larger performed best overall.
