If you ask me, I'd better walk. But I can't.
PS
Walking releases brain-derived neurotrophic factor, playing FPS does not.
Your classic comment certainly stands, though. Based on how they recruited their testing sample, it could easily be that the gamer kids were just wealthier. Many likely confounders aren't mentioned in the study all.
But whether or not there's causation involved, this study tells us precious little about gaming and "cognitive performance" in general, since the stop-signal and n-back tasks they used have obvious connections to gaming but very little relevance to most other areas of cognitive functioning (of course kids who play video games for hours every day will probably respond quicker to which way an arrow on a computer screen is pointing).
"researchers stress that this cross-sectional study does not allow for cause-and-effect analyses, and that it could be that children who are good at these types of cognitive tasks may choose to play video games."
Plus I am not sure that this is "better" cognitive performance, vs just "different". Perhaps kids who don't play video games are better at e.g. music? The article doesn't go into that.
Likewise I am not sure that video games are necessarily more stimulating that other real-world activities. Sure there are lots of boring things we make kids do, but there are also other joyful things that they really like too which are "real world" (adventure playgrounds, lego, swimming parks etc)
Eventually I stared messing about more inside the framework, now I work as an SRE for a streaming service. Never pursued software development as I thought I was too stupid, and now pay would be too shite as a junior dev :)
In a sense Blizzard entertainment just happened to "save my life" (I'm certain I would have a dogshit life without this, many reasons).
I think more games should embrace modding like Blizzard games do/did with maps, workshops (while not being minecraft).
I absolutely think that it's your PoV that's correct rather than the articles.
Maybe it's the kids with better cognitive performance that like videogame better. I wouldn't find that unlikely considering it's more mentally stimulating than other "real-world" activities.
Also, I personally learned to code by writing bots for an MMORPG, so I definitely owe my career to videogames.
