People who grew up during the era of video games probably heard their parents scolding them for playing too much. “You’ll rot your brain,” they might have said. As it turns out, they couldn’t have been more wrong

A study out of Florida State University has shown that the 2011 video game Portal 2 is a better workout for a person’s brain than popular software specifically designed for brain training. Val Shute, the researcher in charge of the study, had participants separated into a group that played Portal 2 and a group that used Lumosity (software advertised as a brain workout).

After participants had played their designated game for eight hours, they were instructed to take a variety of standardized cognitive tests. The Portal 2 players showed more improvement in several of these tests, compared to the Lumosity participants, who did not perform better than Portal 2 players in any of them.

Shute told Popular Science that the goal of this study was to see if video games helped with neuroplasticity—which is the idea that the adult brain can grow with training and playing.

Portal 2 released in 2011 for the Xbox 360, Playstation 3, and PC. It features a silent main character, Chell, who is forced to work with her previous nemesis, the A.I. GLaDOS, to solve puzzles while trapped in the depths of Aperture Laboratories. It is easily found at gaming retailers or as a downloadable version.
