Psychological Science: While it’s well known that using a cell phone while driving is a
recipe for disaster, A study from psychological scientists Warren
Brodsky and Zack Slor of Ben-Gurion University of the Negev found
evidence that the music teens listen to may also have a hazardous
influence on their driving. And it’s not just fiddling with the volume or trying to skip a song
that divert a person’s attention away from the road, the music itself
can interfere with teens’ ability to stay focused on driving. “Drivers underestimate in-car distraction from activities, which are
widely acceptable but not necessarily safe, involving a range of mundane
activities such as simply listening to music,” the researchers write in
the journal Accident Analysis and Prevention.
The researchers recruited 85 novice drivers between 17 and 18 years
old. Just over half of the participants were male, and on average they’d
had a driver’s license for about 7 months. Each participant was
assigned to drive a series of routes along with an experienced driving
instructor in a specially wired car.
On two of the 40-minute drives, the teen driver was asked to bring
along a playlist of their own music to listen to. For the other four
drives the participant either had no music, or listened to an
instrumental soundtrack specially designed by the researchers to
encourage safer driving.
After each trip, subjects completed a post-trip questionnaire rating
their ability to drive safely and their perceived level of enjoyment
from the music. The accompanying driving instructor wrote a brief
commentary describing the driver’s behavior on the trip, and then
completed a scale to tabulate any driving errors that occurred.
According to data collected from the vehicles, the teens played their
own music at much louder volumes than the safe-driving music. They also
rated their mood as significantly higher when listening to their own
music.
However, they also had significantly more driving errors when they
were listening to their own music, including dangerous behaviors like
speeding, aggression, and weaving.
All 85 subjects committed at least three serious safety errors in at
least one of the six trips; 27 received a verbal warning from the
driving instructor, and 17 required steering or braking by the
instructor to prevent an accident.
“Young-novice drivers remain more prone to distraction as they are
less efficient in processing visual information needed to drive safely
while engaging in other non-driving tasks – such as music listening,”
Brodsky and Slor conclude.
Interestingly, another experiment conducted by Ayça Berfu Ünal of the
University of Groningen found that music didn’t have much of an effect
on more experienced drivers. In fact, under certain conditions it may
even help improve drivers’ performance.
A group of 47 drivers in their 20s and 30s completed two rounds in a driving simulator: one with music and one without.
For the music condition, participants were asked to bring in a
playlist of their own music.The drivers performed equally well while
driving with music and without music; specifically, drivers were better
at following another vehicle when they listened to music as compared to
when there was no music. Heart rate monitors indicated that listening to
loud music increased participants’ level of arousal while driving.
“It’s fairly logical – people need a certain degree of ‘arousal’ to
stop themselves getting bored. In monotonous traffic situations, music
is a good distraction that helps you keep your mind on the road,” Ünal
explained.
However, she also suspected that while music may not take a toll on
mental effort in experienced drivers, it may have a different effect in
younger, inexperienced drivers.
