Abstract：
:The minimum stimulus necessary to define motion is a change in position from one location to another in time, but past studies have provided evidence that the human motion system integrates motion over more than two positions. In this study we demonstrate strong sequential interactions affecting perceived direction in apparent-motion sequences; a perturbing dot can bias the perceived direction of motion between two test dots to which it is relatively close in space (up to 100 min arc) and time (up to 300 msec). These sequential interactions suggest a motion mechanism sensitive to the spatial characteristics of motion trajectories; the interactions are greatest for evenly spaced targets positioned along a single axis. The implications for motion-detection models and models based on attention as a mechanism to create apparent motion are discussed.
