Scientists Made a Video Game That Boosts Short Term Memory in Older



Scientists Made a Video Game That Boosts Short-Term Memory 
in Older Adults 
What if, as well as providing a fun way to enjoy our leisure time, video games 
could provide real benefits to our cognitive powers? That's the promise of a 
new musical rhythm game that can not only teach drumming but also 
improve short-term memory. In a study of the game's effects, 47 adults aged 
between 60 and 79 years were split into two groups: one playing the musical 
rhythm game (called Rhythmicity) and one playing a normal word search 
game, for 20 minutes a day, 5 days a week for 8 weeks. 
The difference between the two groups was clear: as players progressed in 
Rhythmicity, the ways it targeted visual perception and selective attention 
had a knock-on effect on short-term memory, as tested through a face 
recognition exercise. 
"As hypothesized, only the rhythm training group exhibited improved short-
term memory on a face recognition task, thereby providing important 
evidence that musical rhythm training can benefit performance on a non-
musical task," write the researchers in their published paper. 
Rhythmicity was developed with drummer Mickey Hart, once of the Grateful 
Dead, and used visual clues to train participants to play a rhythm on a tablet. 
The tempo, complexity, and precision required were all tweaked as players 
progressed. Part of what makes the game special is that it can adapt itself to 
the person playing it, changing the difficulty level to push the player to 
improve without making it so hard that it's going to spoil the gaming 
experience. 
The post-training analysis was done via electroencephalography (EEG) 
during a recognition task involving unknown faces. Rhythmicity players 
were better at identifying faces after the eight-week course, and the EEG 


readings showed increased activity in the superior parietal lobule 

the brain 
region linked to sight reading music and short-term visual memory. 
"That memory improved at all was amazing," says neuroscientist Theodore 
Zanto from the University of California, San Francisco (UCSF). "There is a 
very strong memory training component to this, and it generalized to other 
forms of memory." The researchers behind the study have been busy in this 
field since 2013 when they developed a game called NeuroRacer 

a game 
that's been shown able to significantly improve diminished mental faculties 
and improve sustained attention and working memory in older adults after 
just four weeks. 
That was followed by a game called Body-Brain Trainer, which a recent study 
has found is able to improve blood pressure, balance, and attention in elderly 
people. In that case, heart rate data was constantly being fed back to the 
software so the game could adapt to participants' fitness levels. 
Another game, the virtual reality Labyrinth which engages users in spacial 
wayfinding, has demonstrated that it can improve long-term memory in 
older adults after four weeks of training. A decline in cognitive control often 
comes with getting older, but these games are evidence that there are ways 
to maintain our mental sharpness. 
"These games all have the same underlying adaptive algorithms and 
approach, but they are using very, very different types of activity. And in all 
of them we show that you can improve cognitive abilities in this population," 
says neuroscientist Adam Gazzaley from UCSF.
