<unk>  has been studied using two types of displays: implied motion (left panel) and smooth animations (right panel). Implied events show a series of pictures that suggest a motion, but at a slow frame rate so there is no apparent motion. Smooth animations have also been used, where the animation is briefly interrupted and then participants either indicate whether a static probe is in the same position as the final frame of the animation (right panel), or are asked to indicate with a mouse cursor exactly where the object disappeared. The basic result is that participants either use the mouse to click beyond the vanishing point, or misidentify forward positioned probes as the location where the object disappeared. So, instead of indicating that the actual 0° probe in a rotation event is the same, participants will say that probes appearing 2°-4° past the vanishing point actually seem to be at the vanishing point itself. However, they will quite readily reject probes that are behind the vanishing point by 2°-4°. Schematic of implied motion trial. Rectangle appears for 250 ms, followed by a blank screen for 250 ms (here slightly transparent so previous rectangle is visible). Subsequent orientations are rotated by 17°, with test probes rotations sampled between 0 and up to ±8°. Task is to determine whether third and fourth orientations were identical. People typically incorrectly identify forward probes as being identical, suggesting they have continued the implied motion of the rectangle. The green cube rotates 50° about vertical axis, briefly disappears (250 ms) and probe appears. The task is to determine if cube reappears in exactly the same orientation. In this demo, the cube actually returns 4° further along the trajectory, though it will likely look as if it returned exactly to where it vanished.
