The unicycling clown phenomenon: Talking, walking and driving with cell phone users

Compared with individuals walking alone, in pairs, or listening to their ipod, cell phone users were the group most prone to oblivious behavior: only twenty-five percent of them noticed the unicycling clown. The walkers not using a cell phone noticed the clown over fifty-percent of the time.

Furthermore, the cell phone users had difficulties performing even the simple task of walking, an action that should require relatively few cognitive resources. They walked more slowly, changed direction more often, were prone to weaving, and acknowledged other individuals more rarely.

Dr. Ira E. Hyman, Jr. at Western Washington University, head researcher of the study, says, "If people experience so much difficulty performing the task of walking when on a cell phone just think of what this means when put into the context of driving safety. People should not drive while talking on a cell phone." Furthermore, the research shows that the level of familiarity with the person's real-world environment does not affect their attentional awareness.
