ONR Research Quantifying Video Game Playing and Visual Attention
Posted by jasonwong in attention, perception on January 27th, 2010
“We have discovered that video game players perform 10 to 20 percent higher in terms of perceptual and cognitive ability than normal people that are non-game players,” said Ray Perez, a program officer at the ONR’s warfighter performance department…”
(Researchers Examine Video Gaming’s Benefits from the American Forces Press Service)
Ever since Green & Bavlier’s (2003) paper in Nature, cognitive scientists have known that playing video games increases one’s performance in basic visual attention tasks. This result has been replicated, extended and restricted (only first-person shooter games lead to this effect and not games like Tetris), and it is good to see these results being applied. Many university laboratories have been working on applications, but now with funding from the Office of Naval Research, actual data has been collected with a focus on practical applications. Many times in my own presentations, I say that the new generation of sailors and soldiers are better because of their video game experience, and now I have practical data I can use as evidence. I look forward to seeing new research in this field and hopefully conducting some of my own.
A note: Ray Perez is essentially a funding officer – he has a PhD and understands the research, but he mostly controls the purse strings and gives money out to universities, industry, and government research labs (such as the one I work for) to do the work. It is disappointing that the article describing this research seems to attribute all the work to Dr. Perez, which is incorrect. He certainly made the research possible with ideas and (most importantly) money, but another organization carried out the work and should be credited in the article.
I am giving a Google Tech Talk today!

My friend from graduate school, Ricardo Prada, now works at Google in the User Experience Group. He saw that I was in the Palo Alto area for a week on a work project, and he invited me to give a Google Tech Talk. It was an opportunity that I could not turn down (not that I would ever want to!). After about a month of work on this talk and hours of practice, today is the day. Here is the talk announcement:
Google tends to record these talks on video and put them up on YouTube, so I hope this occurs with mine. I’ll link to it as soon as it’s up.
Human Factors in the News
Posted by jasonwong in attention, automation on October 23rd, 2009
The Human Factors and Ergonomics Society conference took place this past week in San Antonio, TX. I saw a lot of interesting talks that are relevant to my work with the Navy, and I got to see a lot of friends from my previous life as an undergrad at the University of Illinois and grad student at George Mason University.
I am honestly amazed, however, that this story happened during the Human Factors conference:
Pilots missed Twin Cities by 150 miles – but how?
WASHINGTON — Were the pilots distracted? Catching up on their sleep? Federal investigators struggled to determine what the crew members of a Northwest Airlines jetliner were doing at 37,000 feet as they sped 150 miles past their Minneapolis destination and military jets readied to chase them. Unfortunately, the cockpit voice recorder may not tell the tale.
A report released late Friday said the pilots passed breathalyzer tests and were apologetic after Wednesday night’s amazing odyssey. They said they had been having a heated discussion about airline policy. But aviation safety experts and other pilots were frankly skeptical they could have become so consumed with shop talk that they forgot to land an airplane carrying 144 passengers.
They did not respond to communications from air traffic control, they missed every alert the flight management system threw at them… who knows what else they missed? Was it a case of pilot fatigue? Inattentiveness due to a heated discussion?
And if it WAS all due to a heated discussion, what does that mean for us drivers? No more passengers in the car? If you get into an argument or too involved in a conversation that you have to pull over?
Insanity! It seemed like everyone was talking about this story. At least you had 1000+ human factors professionals on the case!
Obama bans “Text Messaging” for federal workers like me
President Obama banned text messaging while driving for all federal workers yesterday. Good.
I wish the government would choose a broader term than “text messaging”, however. The ban encompasses e-mail on phones as well, and also futzing with a GPS while driving (which I am certainly guilty of). From the order itself:
(b) “Texting” or “Text Messaging” means reading from or entering data into any handheld or other electronic device, including for the purpose of SMS texting, e-mailing, instant messaging, obtaining navigational information, or engaging in any other form of electronic data retrieval or electronic data communication.
I wish the White House chose a broader term than “text messaging,” though. Most people hear “text messaging” and think – well, text messaging – and may decide the ban does not cover other text input or activities that draw the eyes away from the road. Obtaining navigational information is certainly not text messaging.
And if I wanted to get really nitpicky – isn’t tuning your radio a form of electronic data retrieval? Hmmmm. OK, probably not. Though I bet finding that one song on my iPod is.
Cell Phones and Driving: Still bad, but who is listening?
The New York Times has an article today about the risks of distracted driving. What is amazing about this is that everyone knows talking/texting while driving on a cell phone is bad for you, yet some of us continue to do it.
“We’ve spent billions on air bags, antilock brakes, better steering, safer cars and roads, but the number of fatalities has remained constant,” said David Strayer, a psychology professor at the University of Utah and a leading researcher in the field of distracted driving.
“Our return on investment for those billions is zero,” he added. “And that’s because we’re using devices in our cars.”
The article looks at driving research from one of the world’s experts – David Strayer from the University of Utah, and it takes a look at the policy side of things, too. This is an excellent example of where cognitive psychology research intersects with public policy. Why is it so hard to put down the phone?
Others cite more fundamental reasons to block any such legislation. “To me, the death of freedom is far worse than the risk of talking on the phone while driving,” said Carl Wimmer, a state representative in Salt Lake City who successfully fought a bill this year to ban talking while driving. “Why pick on cellphones?” he asked, noting that distraction comes in many forms. “You can’t legislate against stupidity.”
Exactly. We should repeal the ban on drunken driving while we’re at it, too. Ugh.
But not all cell phone ban opponents are as stupid as Carl Wimmer. Some actually make a reasonable point.
“I should pay attention to the road,” [19-year old University of Utah student Anne McLaren] said afterward. But sometimes it’s hard to ignore the phone, she added, like when her parents want to reach her. “My dad gets more mad if I don’t have the phone than if I’m talking and driving.”
And many parents can attest to that.
