| Abstract: | Postural stability is critical for our ability to engage in other behaviors and can be influenced by several factors, including changes in optic flow. In situations where postural stability is degraded for prolonged periods of time, motion sickness commonly results. The current research examined how the complexity of a motion stimulus and the coupling of a motion stimulus to the actions of the participant influenced postural sway and motion sickness. Differences in incidence of motion sickness and postural sway characteristics emerged across conditions. In particular, postural sway of participants who became motion sick was characterized by increases in magnitude and spatial complexity but by a decrease in temporal complexity compared with participants who remained well.
