There's a significant controversy over the value of games that are designed to improve people's mental faculties, as some studies have indicated that brain training only helps prepare you for similar tasks, while others indicate that general improvements are possible. But there turns out to be a type of game that is known to boost a variety of skills, from decision making to tracking multiple objects: standard action games. A study, released today by Current Biology attempts to explain how these video games can produce such wide-ranging improvements.

The authors of the study argue that the root of all these tasks involves making a probabilistic inference, where complete information is missing, so people have to make a best guess based on known odds. Video gaming, in their view, increases the efficiency at which people can process the odds and make an accurate decision—gamers simply can do more with less. As a result, any task of this sort sees benefits.
