Violent video games like "Call of Duty" can help trigger-happy players make decisions faster in real life, according to a study released on Wednesday


"These benefits of video games stem only from action games, which almost always means shooter games, where you go through a maze and you don't know when a villain will appear," researcher Daphne Bavelier said in a statement.


The study, published in the journal Current Biology, involved testing 26 people aged 18 to 25, none of whom had played shooting games before, over several months.

Half of the participants played 50 hours of shooting games like "Call of Duty" and "Unreal Tournament" while the other half played 50 hours of a strategy game, "The Sims 2."

They were then given various tests such as deciding which direction a group of dots on a screen was moving at varying speeds, and deciphering which ear was hearing noises.

The researchers found that the group who had played the shooting games was able to make judgments faster and more accurately. They were found to be 25 percent better at decision making.
