STONY BROOK - It's well-documented that texting while driving can be extremely dangerous, but a new study says texting while walking may not be the brightest idea, either. Researchers at Stony Brook University tested people's ability to walk to a target while texting and while talking on cell phones. Participants' vision was obscured except for the phone they were holding. The study showed that those who were texting veered significantly off-course, in some cases more than a meter or so. Texting and walking in a living room could mean bumps or bruises from a coffee table, but on a busy city street, it could mean the texter is off of the sidewalk and into traffic.

Professor Lisa Muratori says the results show that the brain can only multi-task to a certain point before some abilities can be compromised.
