It seems like video games are just about everywhere. 00:00:00
People have them in their homes, on their computers, and even small handheld versions. 00:00:03
NASA uses simulators, which are similar to video games, to train and help pilots stay focused while flying a plane. 00:00:07
Derived from this research, NASA researchers have incorporated the use of video games 00:00:14
to help treat patients with Attention Deficit Hyperactivity Disorder. 00:00:19
Linda Beth Bureau explains. 00:00:23
Have you ever met someone with Attention Deficit Hyperactivity Disorder, or ADHD? 00:00:30
Chances are that you have. 00:00:36
It is estimated that as many as 6% of all Americans suffer from this problem. 00:00:38
Common symptoms of ADHD can include poor attention span, impulsive behavior, and, in some cases, hyperactivity. 00:00:43
Currently, drug treatment is the most widely used approach to control the unwanted behavior associated with ADHD. 00:00:51
But would you believe that playing video games might help people with ADHD control their behavior? 00:00:58
Researchers at NASA Langley Research Center and Eastern Virginia Medical School have been conducting research 00:01:05
which shows that the use of a specially adapted video game controller, 00:01:11
in conjunction with something called biofeedback, may drastically change the way we treat ADHD. 00:01:16
We came up with this idea for a way to treat ADHD in children with our work in flight simulators 00:01:23
where we were interested in pilots' attentiveness and how to improve that. 00:01:29
We connected their brainwaves to the flight simulator so that it affected how much control they had over the flight simulator. 00:01:33
We decided that this might have some usefulness in brainwave biofeedback training, 00:01:39
and we substituted video games for the flight simulator, 00:01:44
and that brought the element of motivation, the entertainment value, into biofeedback training. 00:01:47
Biofeedback is a treatment technique that teaches patients to train and control normally involuntary body functions, 00:01:53
like brainwaves, by using displays of signals from their own bodies. 00:01:59
With the aid of a biofeedback machine, patients with ADHD can learn to train the brainwaves that are associated with focusing. 00:02:03
Patients train these brainwaves by increasing the strength of high-frequency beta waves 00:02:10
and decreasing the strength of low-frequency theta waves. 00:02:15
Practicing these brainwave changes has been shown to lead to an improved ability to pay attention. 00:02:18
These brainwaves can be trained much like an athlete trains his muscles. 00:02:24
For example, when a pitcher throws a ball towards home plate, 00:02:28
if he is off the mark, then he must adjust his delivery the next time he throws the ball. 00:02:32
Biofeedback training works similarly. 00:02:36
If a patient's brainwaves are not on target, then the patient must adjust his brainwaves to meet the desired goal. 00:02:39
So, just as the pitcher uses his muscles to adjust his delivery, the patient uses his mind to adjust his brainwaves. 00:02:45
Video games offers the element of motivation. 00:02:52
They make the training, biofeedback training, entertaining for children. 00:02:56
Biofeedback training typically is just showing children displays of their brainwaves and asking them to control that. 00:03:01
What we've done is embedded that in an entertaining, enjoyable activity. 00:03:08
This technology works by connecting a child's brainwaves to a video game controller. 00:03:12
In the NASA EVMS study, several off-the-shelf video games would link to the biofeedback signal from the patient's brainwaves 00:03:18
through the handheld controller that guides the game's action. 00:03:25
When the game was activated, the patient's brainwaves actually became a part of the game. 00:03:29
While a patient is playing a car racing game, for example, 00:03:35
the sensors pick up high-frequency beta waves and low-frequency theta waves from the player's brain. 00:03:38
If the biofeedback machine reads a higher percentage of theta waves, 00:03:44
it sends a signal to the controller which lowers the top speed that the player's car can reach. 00:03:48
To increase his top speed, the player must increase his percentage of beta waves. 00:03:53
The player learns through trial and error to produce more beta waves and not limit his car's top speed. 00:03:58
With enough training, changes in the patient's brain become automatic 00:04:04
and can lead to improved attention and behavior all the time. 00:04:08
I would like to see this available to people to be able to bring into their home 00:04:12
and enjoy the benefits of biofeedback training through entertaining activities. 00:04:16
Home versions of this technology are currently being developed 00:04:21
that would incorporate sensors embedded into a helmet to measure players' brainwaves. 00:04:24
If this technique continues to prove to be effective, 00:04:29
one day kids may actually have a good excuse to play video games. 00:04:32
