Game theory: New approach shows promise for memories

Researchers are finding that playing certain video games can help residents boost their ability to recall prior events.

By playing three-dimensional video games, seniors can boost the formation of memories, according to neurobiologists at the University of California in Irvine. 

In addition to improving eye-hand coordination and reaction time, these games also may help people who lose memory as they age or suffer from dementia. Full findings appear in The Journal of Neuroscience.

For their work, Craig Stark, Ph.D., and Dane Clemenson, Ph.D., of UCI's Center for the Neurobiology of Learning & Memory, recruited non-gamers to play either a video game with a passive, two-dimensional environment (“Angry Birds”) or one with an intricate, three-dimensional setting (“Super Mario 3D World”). 

Participants played the games for 30 minutes each day over two weeks.

Before and after the two-week period, players took memory tests that engaged the brain's hippocampus, the region associated with complex learning and memory. They were given a series of pictures of everyday objects to study. 

Then, they were shown images of the same objects, new ones and others that differed slightly from the original items and asked to categorize them. Recognition of the slightly altered images requires the hippocampus, Stark says, and his earlier research had demonstrated that the ability to do this clearly declines with age. This is a large part of why it's so difficult to learn new names or remember where you put your keys as you get older.

Those playing the 3-D video game improved their scores on the memory test, whereas the 2-D gamers did not. The boost was not small, either. 

Memory performance increased by about 12%, the same amount it normally decreases between the ages of 45 and 70.
