Children Who Play Video Games Are Better at Working Memory Tasks

Basically, people who are exposed to simulations (video games) as a child have more knowledge/memory/awareness of patterns that are used in these games. Due to the general fact that video games tend to drive players to a goal, people who played video games as a child tend to have an easier time focusing on the details of an environment (in this study, processing 3d objects) and ignore details that are not relevant for the task at hand.

It is important to note that the difference between [past] video game players and non video game players, is that the difference in ability to process these 3d objects lessened once players spent time in training exercise (presumably from the article says, Super Mario 64).

Not groundbreaking, but it makes solid sense to me. The rewards-driven nature of games helps promote patterns of learning/memory that help accomplish the task. These same patterns stay with the person as they get older and they can apply the same principles to tasks outside of video games.
