Abstract Details

2008, Doctor of Philosophy, Miami University, Psychology.
Postural stability is critical for our ability to engage in other behaviors and can be influenced by several factors, including changes in optic flow. These changes can occur both independently of our own actions and as a result of our own behavior. 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 both postural sway and motion sickness. The results suggest that when the structure of the optic flow is similar to that of our own postural sway, motion sickness is more likely than when the structure is simple. Likewise, if our postural actions result in incorrect perceptual consequences, motion sickness is also more likely. In the latter case, both traditional postural measures and dispersion analysis (a type of fractal analysis) found differences in postural sway for sick and well participants.
