It's always good to be on the lookout for unicycling clowns and other dangers while on the move, but if you're talking on a mobile phone, chances are they will escape your attention, according to research highlighted in the Independent. Researchers at Washington University observed pedestrians as they crossed the campus either talking on a mobile phone, listening to a personal music player, in conversation with another pedestrian, or walking alone, without any electronic devices.The researchers noted aspects of their walking behaviour – the time it took them to cross the square, whether they stopped, zig-zagged or stumbled, direction changes , and collisions or near collisions with others. The researchers also observed whether they noticed an obvious distraction just off the walking path, like a brightly-colored unicycling clown ("very rare on campus pathways", according to the study authors).
Only 25 percent of people using their mobile phones noticed the clown, compared to more than half of people in the other groups. Pedestrians talking on a mobile phone were slower, change direction more, have difficulty navigating. The study did not blame electronic devices per se (61% of people using a music player saw the unicyclist) or on having a conversation (chatting couples were the most vigilant with a 71% detection rate).
Instead, mobile phone users fail to notice what is going on around them due to inattentional blindness. The study provides further evidence of the dangers of phone driving and will be published in the December issue of Applied Cognitive Psychology.
