A- Experimental paradigm: schematic representation of one trial (left panel). Two masks were shown to the left eye of subjects at an alternating rate of 9.45 Hz for 4 s. The pattern of dots was presented to the right eye for variable durations (see methods) and had a random onset time between 0.5 s and 3.5 s after trial start. After 4 s of mask presentation subjects had to indicate with a button press whether they had detected any moving dots or not (2AFC). Four types of motion patterns of dots were used in the experiments (right panel). B- Radial motion, C – Random Walk motion, D- Random trajectories motion, E- Biological motion.
