- Abstract
- Sinusoidal tones with 200 and 400 ms duration were presented binaurally with equal probability every 1300 ms.Subjects had to indicate by a button press whether a short or a long tone was presented in the current trial. Thestimuli were presented with standard (p = 0.84; 1000 Hz) or deviant (p = 0.16) pitch. These occasional pitchchanges were task-irrelevant. Pitch changes consisting in a frequency increase/decrease of 1%, 3%, 5%, or 10%resulted in prolonged reaction times in the duration discrimination task and MMN, P3a, and RON, componentsin the event-related brain potential that are elicited in the context of distraction. These measures being sensitiveto task-irrelevant pitch changes did increase as a function of pitch deviancy. The findings demonstrate thatrather small task-irrelevant changes in a repetitive sound can cause distraction on a behavioral andelectrophysiological level. Moreover, the psychometric functions supports the view that distraction is not an allor-none-phenomenon and confirms the hypothesis that these event-related brain potential measures are relatedto each other.
