Can You Easily Talk and Drive?

Ever find yourself distracted as you drive and talk business on your cellphone? That's not surprising because your brain cannot easily juggle both. University of South Carolina researchers show that as people prepare to speak or actually speak, they are "four times more distracted than as they listen." Speaking puts far more demands on the brain than listening. Here's why...

"People can tune in or out as needed when listening," contends Dr. Amit Almor, lead researcher. Added to that, he determined, "It's really an attention problem, not really about holding the phone in your hand."

Keep these findings in mind if you conduct business on your cellphone while driving...

• The greater the urge to speak, the greater the distraction from the visual task.
  

• When applied to the visual task of driving, results show that simply using hand-free devices is not very helpful.

• With driving, talking on the phone is very different from talking to someone in the car.

• When someone sits next to you they act as a second set of eyes, and can alert you to things that someone on the other end of your cellphone can't.

Dr. Almor's study really adds weight to earlier Carnegie Mellon studies which show that just listening to a cell phone while driving is a significant distraction, and it causes drivers to commit some of the same types of driving errors that can occur under the influence of alcohol.

This study "used brain imaging to document that listening alone reduces by 37 percent the amount of brain activity associated with driving. This can cause drivers to weave out of their lane, based on the performance of subjects using a driving simulator."

Almor’s findings are particularly relevant in light of recent statistics.

The National Highway Traffic and Safety Administration (NHTSA) reported in April that 25 percent of all car accidents are caused by distractions. A survey done by Nationwide Mutual Insurance in 2007 indicated that 73 percent of drivers talk on cell phones while driving. Given that cell-phone sales have vaulted to 254 million in February 2008 up from (4.3 million in 1990), according to the Cellular Telecommunications & Internet Association, there is good reason for researchers to study the brain and how talking and listening on a cell phone interferes with driving a car.

I have used a Blue Tooth earphone and have engaged in conversation as I was driving so this research was new to me. While I felt I was completely concentrating on my driving, this makes me think twice.
