Effects of Simulated Viewpoint Jitter on Visually Induced Postural Sway
Abstract
In this study we examined the effects of simulated horizontal and vertical viewpoint jitter on the vection and postural sway induced by radial patterns of optic flow. During each trial, observers were exposed sequentially to 20 s periods of radially expanding flow, radially contracting flow, and static visual scenes. For half the trials, simulated viewpoint jitter was added to the radially expanding/contracting optic flow patterns. In experiment 1, we found that, while this jitter increased the backward postural sway induced by radial expansion, it actually decreased forward postural sway induced by radial contraction. However, in experiment 2 we found that jitter increased both the forward and backward vection induced by radially expanding and contracting flow patterns. We conclude that the processes involved in postural control are more sensitive to the sensory conflicts generated by viewpoint jitter than those involved in the perception of self-motion, and that the observed asymmetries in forward and backward sway are ecological in origin.

Palmisano et al. (2009) found that adding visual jitter to a stimulus that created forward vection increased sensory conflict but resulted in stronger vection; no sickness data were reported.
“Support for this assumption is also provided by Palmisano et al. (2009), who added visual jitter to a stimulus that created forward vection. Despite increasing the sensory conflict by adding the visual jitter, results showed stronger vection than the same visual stimulus without jitter. However, no sickness data were reported in this study.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
