The motion aftereffect as a universal phenomenon in sensory systems involved in space orientation: II. Auditory motion aftereffect

Abstract

Adaptation to sound source motion can cause noticeable changes in spatial perception of the following sound stimuli. Neural mechanisms of selective sensitivity to motion are the basis of this phenomenon, called the auditory motion aftereffect. The auditory motion aftereffects were demonstrated under different stimulation conditions, both after the presentation of different motion models and in the real sound source motion. The auditory aftereffects are specifically characterized by its spatial and frequency selectivity as well as by the optimal motion velocity at which the effect is maximal. These features and the presence of the intersensory motion adaptation effects indicate a common nature of the auditory and visual motion aftereffects and allow suggesting the existence of the common system of motion adaptation for different modalities that provide spatial orientation.
