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.
Would those decisions be made with a keyboard & mouse or a controller? :p
