Measuring the Amplitude of the N100 Component to Predict the Occurrence of the Inattentional Deafness Phenomenon

Abstract : In the field of aviation, a significant amount of accidents are attributable to a phenomenon called inattentional deafness, defined as “the propensity to remain unaware of unexpected, though fully perceptible auditory stimuli such as alarms”. The present study aimed at testing the impact of cognitive load on the perception of auditory information unrelated to the piloting task at stake in an ecological flight context. Pilots had to perform simultaneously a piloting task (i.e., approach and landing) in a A320 flight simulator and a passive auditory oddball task, with standard (80%) and deviant (20%) tones played. Lower N100 amplitudes were found in response to deviant tones when the piloting task was associated with a high cognitive load than a low cognitive load, demonstrating that cognitive load disrupts the perceptual processing of auditory stimuli, which is likely to trigger inattentional deafness in pilots.
