Fig. 1.

Time course of a (test) trial. After 1 s of fixation and a gap period (target blanked for 300 ms), the target started moving horizontally at a constant velocity. After 600 ms, the target was blanked for 800 ms (blanking period) and continued moving for another 600 ms. Target velocity (15 or 20°/s) and direction (to the left or to the right) were randomized across blocks but kept constant within a block. Each frame in the figure corresponds to a specific period of the trial, with duration reported in parentheses.
