Stimulus schematic for Exp 1 (gap closure) with depth motion components (bold black line) added to the horizontal motion vectors (gray). (A) Pure-depth looming added motion perpendicular to the horizontal component, thus decreasing the angular speed of the object. (B) Towards-observer looming added motion in the direction of the observer thus maintaining angular position and speed.
