有人建议，添加振荡运动分量可以促进视觉诱导的自运动感知（运动），即使它们在有关自运动的视觉和前庭信息之间产生实质性冲突。在此报告的心理物理实验中，改变了正弦振荡的属性，例如相位或幅度的一致性，以研究附加振荡的促进作用背后的知觉机制。结果表明，主要视觉运动的正交方向上的相干振荡可以促进运动强度，而此外，自运动感知的强度和视觉模式的感知刚性作为刺激属性的函数而协变。这些结果表明，均匀振荡首先增强视觉模式的感知刚性，然后被感知为更刚性的视觉模式会诱导更引人注目的自运动感知
It has been suggested that the addition of oscillating motion components can facilitate visually induced self-motion perception (vection), even though they generate substantial conflicts between visual and vestibular information about self-motion In the psychophysical experiments reported here, attributes of sinusoidal oscillation, such as consistency in phases or amplitudes, were varied in order to investigate the perceptual mechanism underlying the facilitative effects of additional oscillation The results show that coherent oscillation in the orthogonal direction of the main visual motion can facilitate vection strength, whereas variation in the phases or nonuniform amplitude impairs it Furthermore, the strength of self-motion perception and the perceived rigidity of the visual pattern covaried as a function of stimulus attributes These results suggest that uniform oscillation first enhances the perceived rigidity of the visual pattern, and then the visual pattern that is perceived as being more rigid induces more compelling self-motion perception
