Stimuli used in Experiment 3. Top left: Initial condition scene. Each test condition involves a modification to an object in one of the four corners of the picture. In four cases, the shape is projected with a local-linear projection, e.g., as shown on the center. In four other cases, non-geometric modifications are performed, e.g., right. Besides, in a post-experiment survey we show participants a composite image (bottom left) containing all four projection manipulations.
