چکیده انگلیسی
Internal clock models postulate a pulse accumulation process underlying timing activities, with more accumulated pulses resulting in longer perceived durations. We investigated whether this accumulation is reflected in the amplitude of event-related brain potentials (ERPs) elicited by auditory stimuli with durations of 400-600Â ms. In a duration discrimination paradigm, we found more negative amplitudes to physically identical stimuli when they were judged as longer than the memorized standard duration (500Â ms) as compared to being classified as shorter. This sustained negativity was already developing during the first 100Â ms after stimulus onset. It could not be explained as a bias to respond with a particular hand (lateralized readiness potential), but rather reflects a processing difference between the tones to be judged as shorter or longer. Our results are in line with models of time processing which assume that higher numbers of accumulated pulses of a temporal processor result in an increase in perceived duration.
