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 veloci- ties (comparing 4.5 and 9°/s) and vertical (compared to horizontal) saccades.
