But the important aspect is the sensory conflict
between actual orientation and what is anticipated.
Some propose theories of motion sensitivity and visual vertigo result in a sensory conflict
, or mismatch between the visual, vestibular and somatosensory systems.
All this sensory conflict
makes you feel like you're starring in a movie, detached from the wild and whirling world, lit by your own personal spotlight.
On the other hand, a 3-D object flying off the screen causes a sensory conflict
, which intensifies over a longer period.
Sensory reweighting is also important in the situations of sensory conflict
that frequently occur in daily activities; for example, when someone stands next to a bus in movement.
Used as a spinning platform to simulate movement encountered in flight, the chair tests a student's ability to perform standard in-flight tasks of varying complexity while learning to overcome sensory conflict
005) than children with no documented deficit on all posturography trials that presented sensory conflict
The most widely accepted theory is the sensory conflict
theory put forth by Reason (1978) and Reason and Brand (1975).
The most popular explanation of motion sickness, the sensory conflict
theory (Reason & Brand, 1975; Oman 1990) suggests that motion sickness results from the misinterpretation of concurrent sensory input from the visual and vestibular systems.
Traditional explanations of motion sickness are grounded in the concept of sensory conflict
conditions have been shown to have a greater effect on sway in older persons compared with the young (Straube, Botzel, Hasken, Paulus, & Brandt, 1988; Teasdale, Stelmach, & Breunig, 1991; Woollacott, Shumway-Cook, & Nashner, 1986).
Spatial disorientation , then, occurs because, "The three-dimensional environment of flight is unfamiliar to the human body, creating sensory conflicts
and illusions that make spatial orientation difficult, and sometimes impossible to achieve.
