We've covered why commercial brain training apps mostly fail to show real-world benefit. Action video games have a separate, older, and notably different research record, specifically around attention.
What the Research Found
A study in Neuropsychologia examined attention skills in people who regularly play action video games, fast-paced games demanding rapid visual tracking and quick decisions, and found measurable improvements in attentional capacity compared to non-players. This built on earlier work in the same research line examining visual attention specifically.
Why This Is Different From Brain Training Apps
The key distinction is what's actually being measured. Brain training apps claim broad benefits, memory, reasoning, everyday cognitive performance, that research consistently fails to support. Action video game research is narrower and more specific: measurable improvements in visual attention and rapid target detection, skills closely related to what the games themselves demand. That's a much more modest, and much better supported, claim.
Still Narrow Transfer, Just a Different Kind
This isn't evidence that action games make you smarter generally, it's evidence for a specific, well-defined attentional benefit. That's the same near-transfer versus far-transfer distinction covered in the brain training piece, just landing on the more favorable side of it for this particular skill.
The Bottom Line
Not all "brain-boosting" claims about games deserve the same skepticism. Action video games have a real, specific, decades-old research record behind attention improvements, a genuinely different case than the commercial brain-training industry's broader, less-supported claims.
