  Abstract:
A stationary stimulus is perceived to drift in the opposite direction after adaptation to a moving stimulus (static motion aftereffect). It is commonly assumed that positional effects from the static motion aftereffect are mediated by early visual areas. Here we psychophysically showed that these positional effects did not modulate illusory line-tilt aftereffect. Since illusory contours seem to be represented at relatively early stages of visual hierarchy, we suggest that the neural substrates underlying the perception of static motion aftereffect and illusory contours are different.
