Abstract:
A conflict among sensory signals frequently underlies problems of disorientation, vertigo, and motion sickness. In this study, visual information in conflict with vestibular signals was presented to groups of subjects by illuminating the test room for brief periods during angular deceleration, or immediately after termination of deceleration. Trials were otherwise in total darkness. Both primary nystagmus and primary sensations of vertigo were markedly shortened during the periods of darkness subsequent to the intervals of light. In addition, strong secondary reactions both nystagmus and vertigo frequently followed the vision-attenuated primary responses. Author
