Sensitivity to the sudden displacement (phase shift) of a single monocularly presented sinusoidal grating is increased when a static grating of similar spatial frequency is presented to the same eye. If the static grating is presented to the other eye instead sensitivity is, at best, halved. This demonstration implies that monocular and binocular visual pathways differ in their sensitivity to spatial variations of contrast. In addition it provides another example in which the monocular visual pathways are more sensitive to spatial displacements than the binocular pathways.
当向同一只眼睛呈现空间频率相似的静态光栅时，对单眼呈现的单个正弦光栅的突然位移（相移）的敏感度会增加。如果将静态光栅改为呈现给另一只眼睛，那么敏感度充其量减半。这一证明意味着单眼和双眼视觉通路在对对比度空间变化的敏感度方面存在差异。此外，它还提供了另一个例子，即单眼视觉通路比双眼视觉通路对空间位移更敏感。
