引入视觉诱导器的水平振荡可以增强观察者对垂直运动光流模式诱导的垂直自运动的错觉。为了检验增加视网膜图像运动对促进向量的影响，在不同的刺激条件下分析了向量强度，其中视网膜图像的振荡由视觉刺激的运动和观察者的眼球运动决定。结果表明，视网膜上的视刺激振荡调节视向易化，而非视刺激振荡本身。因此，目前的实验显然支持这样的假设，即增加视网膜图像运动在促进向量中起着关键作用。
Horizontal oscillation introduced into a visual inducer can enhance an observer's illusory perception of vertical self-motion induced by a vertically moving optic flow pattern. To examine the effects of increased retinal image motion on the facilitation of vection, vection strength was analysed under various stimulus conditions where the oscillation of the retinal image was determined both by the motion of the visual stimulus and the observer's eye movements. The results indicated that the facilitation of vection was regulated by the oscillation of the visual stimulus on the observer's retina rather than the stimulus oscillation per se. Thus, the current experiment clearly favours the hypothesis that increased retinal image motion plays a critical role in the facilitation of vection.
