Vernier and grating acuity were measured in infants up to 6 months of age using a two-alternative forced-choice preferential looking technique. Vernier resolution was measured using a horizontal vernier grating. The grating was presented on half of the screen while the other half contained horizontal lines which were continuous with the vernier grating. Movement artifacts were eliminated by making both halves of the display move as the offsets were introduced in half of the display field. Vernier acuity, like grating acuity, improved about 3 octaves over the first 6 months of life. Moreover, the vernier resolution of infants, as of adults, was better than grating resolution.
使用二选一的强迫选择优先注视技术，对6个月龄以下的婴儿进行了游标和光栅视力测量。使用水平游标光栅测量游标分辨率。光栅显示在屏幕的一半，而另一半包含与游标光栅连续的水平线。当在显示区域的一半引入偏移量时，通过使显示器的两半都移动来消除运动伪影。与光栅视力一样，游标视力在生命的前6个月提高了约3个八度。此外，婴儿的游标分辨率与成人一样，优于光栅分辨率。
