Table 1.

Target speed (mean and standard deviations across observers) as inferred from the distance between target onset position and saccade endpoint and speed of postsaccadic pursuit, as a function of the speed of the internal motion.

Internal speed	Saccades	Pursuit
5 dva/s	11.92 (0.95)	6.65 (0.53)
10 dva/s	12.20 (1.19)	6.80 (0.61)
15 dva/s	12.06 (1.33)	6.66 (0.48)
