The development of vernier acuity in human infants aged 2-9 months was assessed by a preferential looking procedure using a vernier-motion display. The displacement of vernier offsets gives the impression of motion only when the vernier offsets are detected. Grating acuity of the same group of infants was also measured by a preferential looking procedure. Vernier acuity was found to be superior to grating acuity only after 3 months of age. This superiority of vernier acuity was compared with the superiority of stereoscopic acuity to grating acuity. The two classes of hyperacuity proved to be almost equivalent in terms of their developmental time-courses. A common physiological basis for the development of hyperacuities is suggested.
通过使用游标运动显示器的优先注视程序，对2至9个月大的人类婴儿的游标视力发育进行了评估。只有当检测到游标偏移时，游标偏移的位移才会给人运动的印象。同一组婴儿的光栅视力也通过优先注视程序进行了测量。发现只有在3个月大之后，游标视力才优于光栅视力。将游标视力的这种优越性与立体视力相对于光栅视力的优越性进行了比较。事实证明，这两类超视力在其发育时间进程方面几乎是等效的。有人提出了超视力发育的共同生理基础。
