采用纵向实验设计，测量了4、6、8个月婴儿在跟踪突然变化轨迹时的扫视反应时（SRT）。SRT从4月龄时的595 ms（SE=30）降至8月龄时的442 ms（SE=13）。此外，SRT在高速度（比较4.5和9度/秒）和垂直（与水平相比）扫视期间较低。
Saccadic reaction time (SRT) of 4-, 6- and 8-month-old infants' was measured during tracking of abruptly changing trajectories, using a longitudinal design. SRTs decreased from 595 ms (SE=30) at 4 months of age to 442 ms (SE=13) at 8 months of age. In addition, SRTs were lower during high velocities (comparing 4.5 and 9 degrees/s) and vertical (compared to horizontal) saccades.
