Abstract : The primary objective of the three studies completed was to determine whether motion sickness susceptibility was related to different measures of visual persistence. In these studies, motion sickness susceptibility was determined by exposing the subjects to a rotating optokinetic drum while the electrogastrogram and subjective indices of motion sickness were recorded concurrently. Subjects were tested for persistence of visual cues using one or more of the following procedures: a walking task, a computer simulation task, a temporal measures of vection, and three measures of spatial abilities. In Experiment 1, 50 subjects were tested; in Experiment II, 24; and in Experiment III, 45 were studied. Mixed results were obtained in the three experiments, but in general, those subjects who showed greater persistence, reported more severe symptoms of motion sickness. In addition, those subjects who did poorly on a water level test of spatial abilities, reported greater symptoms of motion sickness. We continue to believe that perceptual/cognitive style is germane to the issue of individual differences in responding to rapidly changing visual environments.
