**Clown on a unicycle**

One experiment displayed how cell phones contributed to inattentional blindness in basic tasks such as walking. The stimulus for this experiment was a brightly colored clown on a unicycle. The individuals participating in this experiment were divided into four sections. They were either talking on the phone, listening to a digital audio player, walking by themselves or walking in pairs. The study showed that individuals engaged in cell phone conversations were least likely to notice the clown.
