Money quote:<p>&#62; "This is the first time that we've been able to take a <i>real world task like a video game</i> and show that the size of specific brain regions is predictive of performance and learning rates on this video game"<p>To be fair, later in the study they mention that a particular sub-class of gaming skills has demonstrable overlap with real-world performance, namely being able to flexibly shift priorities. But taking that phrase out of context is just too tempting.
