A study which will be released in the March issue of the Journal of Experimental Psychology says that drivers who use cell phones tend to be <a href="http://news.com.com/2100-1033-982325.html">more distracted than drivers who stay off the cell phones.</a> The study found that even those drivers who used a hands free style of cell phone suffered from a type of tunnel vision while driving which they call inattention blindness. David Strayer, an associate professor of psychology at the University of Utah, who led the study explained that the <a href="http://www.psych.utah.edu/AppliedCognitionLab/JEP_Applied_Final.pdf">study</a> (PDF Document link) was conducted using a group of 20 volunteers in a driving simulator. Their reaction times and driving performance and style were measured while they used cell phones and while they werent using cell phones. Strayer said that the study revealed that their performance was clearly negatively affected when they drove while a cell phone was in use, regardless of whether it was a hand held or a hands free phone. Phone users tended to follow too closely, braked too late, and generally were less cognizant of fast changing traffic conditions. This results of this study, combined with a 1997 New England Journal of Medicine editorial critical of cell phone use while driving, would seem to buttress the argument of some that cell phone use should be banned outright. It casts into doubt the efficacy of laws, similar to the New York law which allows only the use of hands free units while driving, which have been passed in local communities around the nation. Strayer said that this inattention blindness was not a factor for drivers listening to music or talking to a passenger in the car. Should ALL cell phones be banned while driving?
