See Table 6.4.
| Background | Experiment AIIIE1 found an effect for a stationary visual background reducing simulator side-effects. But this reduction might disappear if attention is forced into the visual foreground. |
| Hypothesis | A visual background in agreement with inertial cues should reduce simulator side-effects, even if the visual foreground is not in agreement with inertial cues. |
| Methods | A circular vection stimuli was provided both with and without a stationary visual background. Measures included per-exposure postural in stability and post-exposure reported simulator sickness. A visual task forced attention into the visual foreground. |
| Results | Postural instability was significantly lower with a stationary visual background (p < .03). |
| Conclusions | The results support the hypothesis. |
