Understanding Change Blindness: A Hazard in Driving

Are we deaf to change blindness? A growing number of automobile accidents are caused by a driver attending to a secondary tasks, for example, talking on the phone, adjusting the radio and text messaging. When sudden changes in traffic occur cognitive attention is necessary to take appropriate action (States, 2001). Yet many people overestimate the capacity of their visual attention necessary to perceive a change (Levin, Momen, Drivdhal, & Simons, 2000). Rensink, O’Regan, & Clark argue that attention is a limited resource and necessary to perceive change (1997). Visual distractions and change blindness can hijack a person's attention making change perception more difficult (Grimes, 1996). Change blindness is a phenomenon where a person fails …show more content…

Research is sparce on the capacity of attention in a multtask environment. This raises an important question as to what is happening with our attentional system when change blindness occurs. Consequently, There are few studies that explore how auditory and visual stimuli share attention and whether un-related auditory processing could undermine a visual change detection task. Additionally, auditory distractions may prove to have a bigger impact on driving than previously thought. At the very least this study is intended to provide individuals with a convincing argument against using their smart phone while driving an automobile and provide support to similar research studies. More research is necessary to further convince drivers the nature of attentional limitations and change blindness on the road. The present study examines a person’s ability to detect change when their cognitive attention is disrupted by an auditory shadowing task. Our first hypothesis predicts that as the level of mud splash is increased, the reaction time to detect change in a scene will increase. Similar results will be found when the experimental condition adds a low level audio and verbal shadowing
