Brain MRI studies have shown that video games develop decision-making skills

Ten years ago at the University of Rochester, they conducted an experiment with gamers, which showed that fans of shooters and action games make more correct decisions per unit of time than supporters of unhurried strategies. This does not directly affect the chance of winning the game, but scientists have noticed that different genres of games set individual vectors for brain development. It was a theory then, but now it has received scientific confirmation from scientists at the University of Georgia.


The researchers used functional MRI to analyze the activity of the brain and its individual structures in real time. Two groups of young people were selected for the experiment, the first group included experienced gamers (they play more than 5 hours a week), the second group included beginners (they play less than 1 hour a week). They were placed in an MRI machine and asked to undergo several tests.

The main purpose of the experiment was to test the speed and accuracy of decision making. The subjects were shown a screen on which dots of different colors moved in random directions. They were given a few seconds to observe, after which the question was asked about where and how the point, chosen at random, was moving. The answer was given only three seconds, after which the task was repeated.

The results confirmed the hypothesis of a decade ago – experienced gamers gave faster and more accurate answers. But the most interesting thing is that MRI showed clear changes in the activity of their brains, primarily in the lingual gyrus, thalamus and additional motor area. Video games have proven to be an effective tool for developing attention, reaction speed, situation assessment and decision making. It remains to learn how to use them specifically for the development of useful skills, and not just for fun.
