Multitasking: You can’t pay full attention to both sights and sounds
The reason talking on a cell phone makes drivers less safe may be that the brain can’t simultaneously give full attention to both the visual task of driving and the auditory task of listening, a study by a Johns Hopkins University psychologist suggests.
The study, published in a recent issue of “The Journal of Neuroscience,” reinforces earlier behavioral research on the danger of mixing mobile phones and motoring.
“Our research helps explain why talking on a cell phone can impair driving performance, even when the driver is using a hands-free device,” said Steven Yantis, a professor in the Department of Psychological and Brain Sciences in the university’s Zanvyl Krieger School of Arts and Sciences.
