Eye and head tracking of an oscillating visual flow was studied in 1-, 2-, and 3-month-old infants using EOG and an opto-electronic system. A pronounced decrease in phaselag of gaze velocity was observed over this age period, from 170 to 70 msec, but gain changed only marginally. Latency of the onset of tracking decreased with age from 860 to 560 msec. During tracking, the velocity of the head showed high frequency components in the 1-6 Hz range, to which the eye movements were reciprocal and without systematic phase lag. This coordination improved with age.
使用眼电图（EOG）和光电系统，对1个月、2个月和3个月大的婴儿进行了振荡视觉流的眼动和头部追踪研究。在这个年龄段观察到注视速度的相位滞后显著降低，从170毫秒降至70毫秒，但增益仅略有变化。追踪开始的潜伏期随年龄从860毫秒降至560毫秒。在追踪过程中，头部速度在1-6赫兹范围内显示出高频成分，眼球运动与之相反且没有系统的相位滞后。这种协调性随着年龄的增长而改善。
