THE ILLUSORY PERCEPTION OF MOVEMENT CAUSED BY ANGULAR ACCELERATION AND BY CENTRIFUGAL FORCE DURING FLIGHT I. METHODOLOGY AND PRELIMINARY RESULTS.

Abstract

Experiments were carried out on three subjects using five basic maneuvers in addition to control periods of straight and level flight. It was shown that angular acceleration and g during flight induce illusory perceptions of motion and displacement of an objectively motionless object. The magnitude of the illusory effects may be great, the fixation object appearing to be displaced as much as 60 degrees from its actual position. The significance of this finding for aviation is evident. The method is adaptable to a number of types of studies concerned with the influence of angular acceleration and g on visual perception.
