Accuracy of Facing Movements Executed without Vision

Abstract

58 university-age men and women were blindfolded and ear-plugged and asked to execute facing movements of 90°, 180°, and 360°. 90° turns were overestimated, while 180° and 360° turns were underestimated. The accuracy of judgments on this task depended upon the individual making the turn, the direction in which the facing movement was made, and the magnitude of the turn requested.
