It has been a long- accepted fact that teenage drivers are at a much higher risk of not just being involved in accidents, but also being killed in car crashes. Although there are many factors that enhance the risk of being involved in accidents for teenage drivers, a new study finds that emotional processes triggered by the brain can impair critical decision-making abilities in a teenage motorist, increasing the risk of being involved in an accident.
The research was conducted by scientists at the University of Turku in Finland. As part of their research, the scientists paired 17 high-risk teen subjects with another 17 low-risk drivers and compared them on car racing video games. As these objects drove cars on their video games, they were presented with a junction where they had to make two choices - either run the yellow light and risk being involved in an accident, or wait for 3 seconds before driving on. The game was designed in such a way that the fastest way of winning the race, was to run the yellow light without being involved in an accident.
The scientists found that the young male drivers in the study who had a much higher tolerance for risk, simply barged on, and took the riskier option without spending too much time thinking. In contrast, the drivers with a lower tolerance for risk were more likely to think for a while, consider their options, and then decide whether they would stop or move on.
In the high-risk category, the teenage male drivers were found to be dominated by emotions that led them into taking risks and driving on regardless of the consequences. These drivers were less likely to experience any major dilemmas when faced with a choice like this. Drivers of the same age with more mature emotional processes were much more likely to stop, and consider before driving on.
