We’ve all been warned about the dangers of using our cell phones while driving. But did you know phone usage when you’re simply walking can make you accident-prone, too?

Scientists at Stony Brook University in New York conducted experiments with 33 male and female adults in their 20s and discovered texters in particular had a tough time walking a  straight line between two points.

The results showed cellphone activity clearly interfered with the subjects’ working memory. Those in the group that was tested as they talked  walked about 16 percent slower than before but still in a somewhat straight line. But those in the texting group veered off course by 61 percent and walked 33 percent more slowly.

The researchers, Eric Lamberg and Lisa Muratori of Stony Brook’s School of Health Technology and Management, said that these findings, published in the current issue of the journal Gait & Posture, “may have significant real-world repercussions.” They believe more cognitive effort is involved in using a cellphone than many of us might expect.

In other words, you may think you’re looking up enough while texting or talking, but your brain apparently isn’t absorbing the information necessary for you to walk normally. This, in turn, may cause you to misjudge the distance to a curb or fail to detect subtle changes in your walking surface — and could lead to a fall.  Have you ever had a cell phone incident?
