Fig. 1.

The schematic illustration of experimental setting (A) and the arrangement of target, occluder, impact zone, and starting cross in the working space (B). The starting position of the target was chosen so that the time that it was visible before disappearing behind the occluder was 400–600 ms. A hit was recorded if a subject’s finger touched the red impact zone at any position touching on the hidden target. (C) Histograms of target speed, distance to impact zone, and time to impact zone in each of the three conditions. The variances of time to impact zone were equivalent across conditions in log space and had exactly equivalent distributions in the low- and high-speed variance conditions.
