Study Finds No Evidence Brain Games Improve Cognition

New research suggests that brain training may not protect older people from memory loss or help them think better.

Florida State researcher Dr. Neil Charness, professor of psychology and a leading authority on aging and cognition, teamed up with Dr. Wally Boot, associate professor of psychology, and graduate student Dustin Souders to investigate claims made by the booming brain-training industry.

“Our findings and previous studies confirm there’s very little evidence these types of games can improve your life in a meaningful way,” said Boot, an expert on age-related cognitive decline.

Their findings appear in the science journal Frontiers in Aging Neuroscience.

Charness, who’s also the director of Florida State University’s Institute for Successful Longevity, said an increasing number of people believe brain training helps protect them against memory loss or cognitive disorders.

“Brain challenges like crossword games are a popular approach, especially among baby boomers, as a way to try to protect cognition,” Charness said.

That popularity has turned the brain-training industry into a billion-dollar business. Brain games are available online and through mobile apps that typically sell for about $15 a month or $300 for lifetime memberships.

But advertising for this rapidly growing business sector has sometimes used inflated claims. The Federal Trade Commission fined one brain-training company $50 million for false advertising, which was later lowered to two million dollars.

“More companies are beginning to be fined for these types of inflated claims and that’s a good thing,” Boot said. “These exaggerated claims are not consistent with the conclusions of our latest study.”

The Florida State University team’s study focused on whether brain games could boost the “working memory” needed for a variety of tasks. In their study, they set up one group of people to play a specially designed brain-training video game called “Mind Frontiers,” while another group of players performed crossword games or number puzzles.

All players were given lots of information they needed to juggle to solve problems. Researchers tested whether the games enhanced players’ working memory and consequently improved other mental abilities, such as reasoning, memory, and processing speed.

That’s the theory behind many brain games: If you improve overall working memory, which is fundamental to so much of what we do every day, then you can enhance performance in many areas of your life.

The team examined whether improving working memory would translate to better performance on other tasks or as the researchers called it: “far transfer.”

In short, no.

“It’s possible to train people to become very good at tasks that you would normally consider general working memory tasks: memorizing 70, 80, even 100 digits,” Charness said. “But these skills tend to be very specific and not show a lot of transfer. The thing that seniors in particular should be concerned about is, if I can get very good at crossword puzzles, is that going to help me remember where my keys are? And the answer is probably no.”

Charness noted that other research finds aerobic exercise, rather than mental exercise, is great for your brain. Physical exercise can actually cause beneficial structural changes in the brain and boost its function. He predicts “exer-gaming,” which combines exercise with brain games, will increase in popularity in the 21st century.
