Get Grandma an Xbox: Video games shown to aid seniors
NEW YORK — It probably won't become as popular as “Grand Theft Auto,” but a specialized video game may help older people boost mental skills such as handling multiple tasks at once.
In a preliminary study, healthy volunteers ages 60 to 85 showed gains in their ability to multitask, to stay focused on a boring activity and to keep information in mind — the kind of memory you use to remember a phone number long enough to write it down.
All those powers normally decline with age, Dr. Adam Gazzaley of the University of California, San Francisco, and colleagues noted in a study released on Wednesday by the journal Nature.
The study was small, with only 16 volunteers training on the specially designed game. Gazzaley and other brain experts said bigger studies were needed to assess whether the game could help people function in their everyday lives. He's co-founder of a company that aims to develop a product from the research.
Specialized video games might one day be able to boost mental abilities not only for healthy adults of middle age or older, but for children with attention deficit disorder, people with post-traumatic stress disorder or brain injury and older adults with depression or dementia, he said.
The work is the latest indication that people can help preserve their brainpower as they age through mental activity. There are “brain training” games on the market and books devoted to the topic. Gazzaley stressed that claims should be backed up by evidence and that his results don't mean any commercial video game can help mental performance. His game was designed to exercise specific abilities, he said.
The game, called Neuro-Racer, involves doing two things simultaneously. A player uses a joystick to guide a car along a hilly, twisting road, steering it and controlling its speed. At the same time, a series of signs — actually colored shapes — appears on the screen. The player is supposed to push a button only when a particular kind of sign appears. Players were scored on how quickly and accurately they reacted to the right signs.
The game progresses to harder levels as a player improves, to keep it challenging.
In a separate experiment with 174 volunteers between the ages of 20 and 79, the researchers found that as people age, driving the car interferes more and more with performance on reacting to the signs.
But for 14 of the 16 participants who played the game at home for a total of 12 hours during a month, the training decreased the amount of interference. In fact, on this measure, they did better than a group of 20-year-olds who played the game for the first time.
The improvements were still apparent six months after the training stopped.
Brain experts unconnected with the study said previous research has shown that older people can improve on mental skills such as multitasking if they are trained. But the training in past multitasking studies was “boring as all get-go,” said Elizabeth Zelinski, a professor of gerontology and psychology at the University of Southern California. Presenting an appealing game like NeuroRacer instead could help people stick with it, she said.
