"Studies have shown that when subjects see an emotional stimulus as opposed to a neutral one, they're slower in making reaction time responses and they're slower when doing a visual search," said Chan. "I wanted to see whether the results would carry over in driving—would we also find more distracted performance in driving?—and we did see that."
Emotionally charged words affected the subjects' driving focus, something that may make driving in real conditions hazardous. Chan says that subjects who viewed the negative words decreased travelling speed when passing the signs and tended to drift and veer from their lane. Conversely, drivers viewing the words with positive connotations sped up when passing the signs—a response the researchers said supported other research.
"There have been studies showing that when you're positively stimulated, your attention broadens, so you perform better when you're in a happy mood," said Chan. "In my results, we also saw that when we looked at the reaction-time data in response to target words, participants actually responded faster in the positive block than in the negative block."
Chan says a precedent already exists Down Under for dealing with this type of distraction, but some places may be harder to convince than others.
"In Australia they have really strict billboard criteria, but in the United States it's less so," she said. "When you're driving in Las Vegas, you'll see a bunch of profane billboards. There are also some really graphic anti-smoking billboards around."
Chan contends that emotional distraction while driving may come from anything from music to news to conversations, so it would be hard to legislate against those types of factors. Self-regulation on the images and language marketers use on billboards could be one way to reduce potential for emotionally related vehicular incidents.
Ultimately, she says, drivers need to take responsibility for their actions behind the wheel, even if it meets reducing the usual driving stimuli such as talking or listening to the radio.
"Any kind of distraction is risky when you're driving. But there would appear to be a larger risk when it comes to emotional stimuli."

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
