Illusory Self-Motion (Vection) May Be Inhibited by Hypobaric Hypoxia
Vection is described as illusory self-motion, or the sensation of body movement produced solely by visual stimulation. It has been previously shown that visual perception and attention can be impaired by conditions of higher altitudes (hypobaric hypoxia). This paper describes the effects of hypobaric hypoxia on vection. The authors used a dark climatic chamber to compare vection strength under both normal and high altitudes. Optic flow displays were used to rate vection perception. They observed significant differences in vection strength measurements between the normal and high altitude conditions, and concluded that vection was inhibited by high altitude. The findings can be used to promote further research in order to increase understanding of altered perception and air pilot safety.
