(1) Playing online “brain-training games” doesn’t help you become smarter or more focused.
(2) Companies behind these training programs promise to sharpen the mental skills of young people and slow their decline in older adults. (3) However, the Federal Trade Commission recently ordered one of the largest companies involved in creating these games to stop
making such claims.
(4) Some scientists claim the games work, but Daniel Simons, a psychology professor at the University of Illinois at Urbana-Champaign, and six other scientists reviewed over 130 studies of brain games and concluded that “many of the studies did not really adhere to what we think of as the best practices.” (5) He also stated that while some of the studies were good and showed that the games help people get better at a specific task, there was a lack of evidence showing that practicing a specific skill resulted in gains in memory or thinking. (6) I asked my friend Mitch, who plays brain games, if he saw any improvements in his grades after playing these brain games over the course of a few months. (7) He laughed and said, “No, but they’re fun to play!”
