Effect of Body Tilt on Auditory Lateralization

A pulsed 1000-Hz pure tone was dichotically presented to 16 Ss in a “lateralization” task under body positions of erect, 30° left and right tilt, and 60° left and right tilt. With the method of limits no significant effect of body tilt on the perception of auditory midline or on the difference limen was found. Significant effects were found for ascending and descending trials on perception of the auditory midline as well as an interaction effect between body positions and left and right ears. The findings were contrasted with those of studies dealing with the effect of body tilt on auditory “localization.”
