||Texture and motion spreading, the aperture problem, and transparency.
When a cross of either static or moving texture is inserted in the intersection of an Ehrenstein figure, the texture and its motion appear to spread outside the cross. It is hypothesized that these phenomena are analogous to neon color spreading, wherein an interpretation of a transparent surface makes the properties of that surface, which are physically visible only inside the cross, appear to spread over its apparent extent. In 3 experiments (N = 12), texture and motion of the cross were attributed to the transparent surface. In addition, the spreading changed the apparent aperture within which the texture and its motion were seen, leading to a corresponding change in the apparent direction of motion.
