summaryClassically, motion sickness is attributed to perceptual issues, such as the hypothetical "intersensory conflict". Theories based on the concept of intersensory conflict have a poor ability to predict who will become motion sick in any given situation. A new approach to the etiology of motion sickness focuses on perception and action in general, and on the perception and control of posture, in particular. I will describe the postural instability theory of motion sickness, and present experimental findings that support a central hypothesis of the theory: That motion sickness should be preceded by instabilities in the control of body posture (both standing and seated), and that only persons exhibiting these instabilities will develop motion sickness.
