Perceptual Vertigo: A Dimensional Study

Abstract

Nine Ss were used in an experiment to determine the effects of peripheral flicker and the degree of structure of the stimulus field upon the incidence and degree of vertigo. The groups of Ss were defined as: (a) Susceptible, (b) Non-susceptible, and (c) a highly-trained Aviator group. Visual presentation of the stimuli was accomplished by means of a hemispheral scene and a wide-angle lens system. Ss' verbal responses were recorded and analyzed. The groups responded with a greater degree of vertiginous response to the stimuli of peripheral flicker in a field of low structure.
