title: Signal onset and task variables in auditory evoked potentials.
abstract: Two auditory evoked potential studies were run to determine the effects of stimulus rise times on amplitude of N1-P2 onset and offset potentials. Onset potentials were reduced with increased onset durations. No consistent relationship was found in N1-P2 offset potentials as a function of stimulus rise time. The effects of listening tasks and stimulus duration were also examined.
