Could a video game make you a better driver? More importantly, could computer software prevent teenagers from making fatal mistakes or even weed out older drivers whose debilities make them crash-prone?
While no one is suggesting that games like Grand Theft Auto will help junior make safer left-hand turns, there are researchers who believe that specially designed cognitive assessment software can train neophytes and aging drivers. Much as games like Brain Age for the Nintendo DS are intended to improve mental acuity, the cognitive software uses bouncing balls and visual memory tests to gauge driving skills.
There are already programs like the American Automobile Association's (AAA) Roadwise Review (about US$15), which is intended to help older people evaluate their driving. The program was based on research by the US National Highway Traffic Safety Administration (NHTSA) and the National Institute on Aging that showed that older drivers who had significant declines in particular cognitive abilities were up to five times as likely to be in a car accident as their peers.
Roadwise assesses eight physical and mental fitness elements related to driving, an especially pressing issue with an estimated 40 million people over the age of 65 expected to be driving by 2020, up from 29 million in 2005, AAA said.
The program, which takes about 30 minutes to complete, amounts to a do-it-yourself driving checkup, including video clips explaining the relevance of tests that check visual search and memory skills.
Taking the test myself, I dutifully squinted at flashing icons and followed instructions to connect numbers and letters in series with a computer mouse. Much to my relief, my test results revealed no impairments, but then again, I'm under 50.
If Roadwise does reveal impairments, AAA reminds users that the computer program is not equivalent to being examined by a doctor and that users may want to take additional steps, like seeing an ophthalmologist if one has difficulty discerning low-contrast objects.
"The program only looks at abilities that are known to decline with age," said Dannielle Sherrets, AAA's manager of traffic safety research and analysis.
So the program may not reveal other problems. Furthermore, Roadwise isn't intended to improve cognitive shortcomings.
IMPROVING SKILLS
There are other programs that will test mental agility and then use subsequent computer training sessions to improve a driver's skills. One such program is an online application called DriveFit (US$89), which was developed by CogniFit, an Israeli firm specializing in cognitive training software. DriveFit uses visual and memory tests to measure 12 driving-related cognitive abilities. It assesses reaction times, as well as a person's propensity to take risks, ability to judge relative speed and process information when attention is divided (for example, driving while talking on a cellphone). The company says people who are slower at processing information in these areas are going to be more dangerous drivers.
I found DriveFit's 30-minute evaluation much more challenging than AAA's. Some sections were like a sophisticated version of Pong, in which I had to track moving objects on the computer screen and quickly judge the relative speeds of moving balls. In other sections, my memory was strained trying to recall ever lengthening number sequences and answer questions based on split-second glimpses of photos of busy intersections.
The results were humbling.
The program found that I was very good at cognitive skills associated with being able to accurately judge how long it would take me to stop at a red light. The program also indicated that I had good visual scanning skills, useful for frequently checking my mirrors.
However, even though I regard myself as a model citizen, I received very low marks when it came to being able to obey traffic regulations, and I was judged to be poor at divided-attention tasks.
I had hoped for some sort of encouraging "Congratulations! You're a superb driver!" message.
Instead, the CogniFit program promised to work on my weak points via 24 computer-based training sessions to be taken over a couple of months.
The program can also be used at the other end of the dangerous-driver spectrum: new teenage drivers.
According to NHTSA, teenage drivers are the only age group more dangerous than retirees and are involved in three times the fatal crashes of all other drivers. A frightening statistic indeed, and one that has encouraged some driving instruction courses to use DriveFit to augment in-car training.
The British School of Motoring uses CogniFit software for training, as does Young Drivers of Canada, a driving school based in Ontario, which has used the DriveFit program with students for more than two years.
Peter Christianson, the company's president, said it trained 30,000 students a year, and each has a DriveFit assessment "before they go into the car so our instructors know their weaknesses."
Studies conducted by CogniFit with the departments of motor vehicles (DMVs) in New York and Maryland found that of the 259 people participating in the tests, 95 had weakness in risk-taking and perception. In subsequent driving-simulator tests, members of this group indeed had twice the accidents of the rest of the group
NOT CONCLUSIVE
But such results are far from conclusive. Clicking on a mouse while staring at a computer screen can't completely predict how a driver will behave behind the wheel of his own car on the road with other drivers, said Anne McCartt, senior vice president for research at the Insurance Institute for Highway Safety.
"So while research has shown a relationship between cognitive measures and crashes, the research is not precise enough to identify a particular driver as being a high risk," she said.
So such tests shouldn't be used as the sole determination of whether to suspend an older driver's license or restrict a teenage driver's permit, McCartt said.
Nevertheless, companies like CogniFit said cognitive assessments could help DMVs and insurance companies determine which drivers may need additional instruction. In fact, Michael Farrara planned to open a high-tech driving program this spring at the Driving Center in Hillsborough, New Jersey. The three-month program will rely solely on driving simulators for instruction and use DriveFit's software for cognitive assessment and training.
While such training is too new to conclusively determine its effectiveness, I'm going to finish mine. After all, it couldn't hurt.
Two sets of economic data released last week by the Directorate-General of Budget, Accounting and Statistics (DGBAS) have drawn mixed reactions from the public: One on the nation’s economic performance in the first quarter of the year and the other on Taiwan’s household wealth distribution in 2021. GDP growth for the first quarter was faster than expected, at 6.51 percent year-on-year, an acceleration from the previous quarter’s 4.93 percent and higher than the agency’s February estimate of 5.92 percent. It was also the highest growth since the second quarter of 2021, when the economy expanded 8.07 percent, DGBAS data showed. The growth
In the intricate ballet of geopolitics, names signify more than mere identification: They embody history, culture and sovereignty. The recent decision by China to refer to Arunachal Pradesh as “Tsang Nan” or South Tibet, and to rename Tibet as “Xizang,” is a strategic move that extends beyond cartography into the realm of diplomatic signaling. This op-ed explores the implications of these actions and India’s potential response. Names are potent symbols in international relations, encapsulating the essence of a nation’s stance on territorial disputes. China’s choice to rename regions within Indian territory is not merely a linguistic exercise, but a symbolic assertion
More than seven months into the armed conflict in Gaza, the International Court of Justice ordered Israel to take “immediate and effective measures” to protect Palestinians in Gaza from the risk of genocide following a case brought by South Africa regarding Israel’s breaches of the 1948 Genocide Convention. The international community, including Amnesty International, called for an immediate ceasefire by all parties to prevent further loss of civilian lives and to ensure access to life-saving aid. Several protests have been organized around the world, including at the University of California Los Angeles (UCLA) and many other universities in the US.
In the 2022 book Danger Zone: The Coming Conflict with China, academics Hal Brands and Michael Beckley warned, against conventional wisdom, that it was not a rising China that the US and its allies had to fear, but a declining China. This is because “peaking powers” — nations at the peak of their relative power and staring over the precipice of decline — are particularly dangerous, as they might believe they only have a narrow window of opportunity to grab what they can before decline sets in, they said. The tailwinds that propelled China’s spectacular economic rise over the past
