Good continuity of arcs induces motion binding(Summary of Awarded Presentation at the 29th Annual Meeting)

抄録

We demonstrated that good continuity, or amodal collinear connectivity, generates an integrated object from component arcs and this integration brings motion binding (Lorenceau & Shiffrar, 1992). Therefore, the existence of corners is not a required factor for motion binding. We presented to observers either a circle or a four-pointed star composed of four arcs with occluders. Motion binding was perceived for both configurations. However, the bound shape appeared rigid with stars, but appeared elastic with circles. This difference probably arises from less tolerance for fluctuation in integration based on continuity than that in integration based on corners.
