The effect of stimulus expectancy on dishabituation of auditory evoked potentials

Having foreknowledge of the type and timing of sensory stimulation modulates the electrophysiological response and can result in short-term habituation. Here we explore if dishabituation is similarly affected.Seventeen healthy subjects were tested with five different auditory stimuli paradigms to see if knowledge of the stimulus train length and/or deviant stimulus affects the amount of dishabituation of auditory evoked potentials. Furthermore...
