Perception of the postural vertical in normals and subjects with labyrinthine defects.

Abstract
9 normal men and 10 men with vestibular defects were studied in a lateral tilt chair for 30 successive settings to the postural vertical. A significant decrease in the average error was found for both groups. The normal Ss exhibited smaller average errors; however, the differences were small particularly after 15 trials and were not statistically significant. (16 ref.)
