Killer Conversations: The Hidden Danger of Cell Phones

Distracted Driving
Reading Time: 2 minutes

Do you play with your phone while driving? 

If so, then you’re lucky to be alive. Here are some scary facts that demonstrate the risk you take, and some are quite surprising:

What’s surprising is the fact that you’re a hazard to yourself and others, even if you’re not texting or reading. Even if you’re looking straight ahead at the highway, and not holding the phone while having a conversation. You need only to be listening to it.

Here are two striking images of the visual center in the back of the head — the part you need for safe driving. The red areas in each picture show the degree to which that part of the brain is activated. As you can see, the one on the left shows a high degree of stimulation. That’s because it’s focused on one activity — driving.  

The image on the right shows what happens to the brain when it is forced to divide its attention between driving and just listening to a simple sentence. It’s as if the light dims in the visual center as the focus shifts to the sides and front of the brain (not shown) where listening and language processing take place.

How do airport control tower operators cope with potentially life-threatening distractions? Watch the video presented below and find out. Dr. Paul Atchley — an expert in translational cognitive science — explains all of the above in a lively talk that includes his creative antidote to the hazards of cell phones and other aspects of modern life in general.
