FRIDAY, Jan. 22
(HealthDay News) -- Slaying orcs, charting military campaigns and gunning down
bad guys might not sound like things seniors would be interested in pursuing
for fun or exercise.
But they might want to
start, some experts on aging say.
Research has found
that off-the-shelf video games have the potential to help seniors age more
gracefully, keeping their minds sharp and responsive through game play.
"There's a
growing body of evidence that suggests playing video games actually can improve
older adults' reflexes, processing speed, memory, attention skills and spatial
abilities," said Jason Allaire, an associate professor of psychology at
North Carolina State University and co-director of its Gains Through Gaming
Lab.
With the advent of the
Nintendo Wii, there's even the potential that video games could provide seniors
with an outlet for physical exercise.
The Wii uses special
controllers that require arm and body movements, and a number of games have
been developed for the system specifically to provide an exercise program.
One study found that a
Wii bowling game boosted the heart rate of players at a senior center in
Pensacola, Fla., by about 40%. The game required that the players, who were in
their 60s, 70s and 80s, hold the controller like a bowling ball and swing it to
hit the pins in a virtual bowling alley.
"The Wii is a
perfect vehicle because it is so easy," Allaire said. "It's in a lot
of senior centers already. Older adults already tend to use it."
The potential of video
games to keep minds sharp was highlighted in a 2008 study in which 40 people in
their 60s and 70s were asked to play Rise of Nations, a real-time strategy game
for computers that can be found in many stores that sell video games.
"We wanted to see
whether we could take an off-the-shelf game and see fairly substantial
changes," said Art Kramer, a professor of neuroscience and psychology at
the University of Illinois at Urbana-Champaign, who participated in the study.
Researchers measured
the cognitive abilities of the players, none of whom had played any video games
for at least two years. They then had half the group play Rise of Nations for
nearly 24 hours total over an eight-week period.
Follow-up tests found
that the seniors who played the strategy video game improved their performance
on tests of memory, reasoning and cognition. There were particular
improvements, Kramer said, in what's called executive control processes --
abilities such as planning, scheduling, dealing with ambiguity and
multi-tasking.
"As we get older,
we show declines in many of those abilities," he said. "As a result
of doing certain things, we end up doing them less often. The kinds of
processes that were exercised in the video game were some of the processes that
older adults show deficits on."
Allaire is part of a
team that has been given a $1.2 million grant from the National Science
Foundation to do further research on whether and how video games can boost
memory and thinking skills in the elderly.
The researchers plan
to have seniors play a Wii game called Boom Blox that involves using weapons
such as slingshots and cannonballs to demolish on-screen targets. The research
will also involve World of Warcraft, an online role-playing game, Allaire said.
The plan is to assess
three aspects of video game-playing that are thought to drive cognitive
improvements in older people, Allaire said. They are:
- Attentional demand. "You have to pay attention to what's going on on the screen and react quickly," he said. "The more attention you expend on the video game, the better you get at focusing your attention."
- Novelty. "There's a lot of research that, when we're put in novel situations or are learning novel things, it activates our brains," he said.
- Social interaction. "People who stay more socially engaged have more cognitive function," he said. "We think people will interact with each other through collaborating and playing the game."
Though the research
efforts show the possibilities of using video games to help aging adults,
Allaire noted that no studies have shown a transfer of video-game skills to
real-world activities.
"Is it going to
help you remember to take your medications, or to remember what you wanted to
buy at the store?" he asked. "That really hasn't been proven."
Kramer said that
seniors should consider video games one of a number of things they can do to
keep themselves sharp.
"I would not
suggest that video games would be the only or even the best way to exercise
those cognitive functions," he said, noting that physical exercise, social
interaction and diet are already proven ways to promote mental abilities as you
get older. "I would recommend they get out and ride a bike. I would
recommend they learn a new language."
