Video Games Lead to Faster and Accurate Decisions

Video Games Lead to Faster and Accurate Decisions

Cognitive scientists from the University of Rochester have discovered that playing action video games trains people to make the right decisions faster.

The researchers found that video game players develop a heightened sensitivity to what is going on around them, and this benefit doesn't just make them better at playing video games, but improves a wide variety of general skills that can help with everyday activities like multitasking, driving, reading small print, keeping track of friends in a crowd, and navigating around town.

The researchers tested dozens of 18- to 25-year-olds who were not ordinarily video game players. They split the subjects into two groups. One group played 50 hours of two fast-paced action video games and the other group played 50 hours of a slow-moving strategy game.

After this training period, all of the subjects were asked to make quick decisions in several tasks designed by the researchers. In the tasks, the participants had to look at a screen, analyse what was going on, and answer a simple question about the action in as little time as possible (i.e. whether a clump of erratically moving dots was migrating right or left across the screen on average). In order to make sure the effect wasn't limited to just visual perception, the participants were also asked to complete an analogous task that was purely auditory.

The action game players were up to 25 percent faster at coming to a conclusion and answered just as many questions correctly as their strategy game playing peers.

"It's not the case that the action game players are trigger-happy and less accurate: They are just as accurate and also faster," author Daphne Bavelier said. "Action game players make more correct decisions per unit time. If you are a surgeon or you are in the middle of a battlefield, that can make all the difference."

The authors' neural simulations shed light on why action gamers have augmented decision making capabilities. People make decisions based on probabilities that they are constantly calculating and refining in their heads, Bavelier explains. The process is called probabilistic inference. The brain continuously accumulates small pieces of visual or auditory information as a person surveys a scene, eventually gathering enough for the person to make what they perceive to be an accurate decision.

Action video game players' brains are more efficient collectors of visual and auditory information, and therefore arrive at the necessary threshold of information they need to make a decision much faster than non gamers, the researchers found.
