The Locus of Adaptation to Auditory—Visual Conflict

Abstract

The site of adaptation resulting from exposure to spatially discordant visual and auditory cues was determined by comparing, for both sensory modalities, shifts in pointings with shifts in estimations of ‘straight ahead’. The exposure task consisted of monitoring a synchronous series of flashes and noises separated 15° laterally by prisms. The shifts it produced for both modalities were of nearly equal magnitude in the two tests. The results suggest that auditory–visual conflict is resolved through recalibrations at the level of sound–head and of eye–head articulations.
