Video games improve decision making skills

People who play action video games are known for their fast reaction times compared to those who don't play the games. And it isn't that they are just "trigger happy," according to researchers. They might be better decision makers as well.

Rather, gamers are better at making quick and accurate decisions based
on evidence extracted from their surroundings (a skill known as
probabilistic inference). That appears to explain why video game playing
skills translate into broad improvements in many kinds of tasks,
regardless of whether those tasks depend on the ability to pay attention
or visual acuity, said Daphne Bavelier of the University of Rochester.
Benefits of video games
Such transfer of learning is notable because most kinds of training lead
to improvements only on the specific task at hand, with limited
improvements on other, even closely related tasks. "That's why when you
give a test that's just a little different from what you did in class,
half the students fall flat," Bavelier said. "Transfer of learning is
lacking."
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," Bavelier said. "It's not exactly what
you'd think of as mind enhancing." Strategy or role-playing games don't
have the same effect.
Faster judgments
Bavelier was able to compare the skills of action gamers versus
non-gamers through a series of carefully controlled and simple
decision making experiments in which people were presented with an array
of dots and asked to identify the primary direction of the dots'
motion. That task was made easier or more difficult by varying the
number of dots moving in the same direction. Video game players were
able to make those judgments faster without sacrificing accuracy,
Bavelier and her colleagues found. Video game players also excelled in
an auditory decision making test in which participants were presented
with noises through headphones and asked to decide whether the sound was
heard in their right or their left ear.
The reason for such broad improvements in performance may be that action
video games don't have a clear "answer". They are inherently
unpredictable. "Unlike standard learning paradigms, which have a highly
specific solution, there is no such specific solution in action video
games because situations are rarely, if ever, repeated," the researchers
write. "Thus, the only characteristics that can be learned are how to
rapidly and accurately learn the statistics on the fly and how to
accumulate this evidence more efficiently."
Non-gamers who play get better too
The researchers don't yet know exactly what happens at the level of
neurons when people play video games to support those decision making
skills. But it's not that video games appeal to people with super vision
or an unusual attention to detail, Bavelier said. Non-gamers who are
forced to play action video games for 50 hours get better at making
informed decisions, too. You don't even have to like playing the games –
you just have to play them.
The researchers include C. Shawn Green, Alexandre Pouget, and Daphne
Bavelier, University of Rochester, Rochester, NY. Their findings are
reported in the September 14th issue of Current Biology, a Cell Press publication.
