Abstract
The induction of an error between a subject's true orientation and his registered orientation in relation to gravity results in auditory mislocaliza-tions of a similar size and time course. The presence of visual cues prevents the development of errors in the interpretation of posture and, accordingly, prevents the development of errors in auditory localization as well. These observations are interpreted as evidence for a spatial reference system responsible for the maintenance of auditory and visual direction constancy. They demonstrate that where a subject hears a sound is dependent not only on the auditory cues at his ears but also on his registered orientatinn in relation to the gravitational force. vector.
