Kinetic contours seen in rotating objects provide evidence about contour function in a kinetic condition. It was observed that (i) when an object with an arc-shaped edge in its outline is rotated, a kinetic contour arises from the rotating arc and bounds a 'figure'; (ii) the kinetic contour not only protects the enclosed area of this figure from the destruction caused by motion, but also interrupts the continuity of the surroundings; (iii) kinetic contours are generally perceived to be organized into discs which appear as amodally completed forms in such a way that one object is hidden behind the other. The fact that oval or outline figures rarely produce kinetic contours is assumed to be due to figural self-sufficiency, which does not require perceptual completion through motion.
旋转物体中出现的动态轮廓为动态条件下的轮廓功能提供了证据。据观察：（i）当一个轮廓带有弧形边缘的物体旋转时，一个动态轮廓会从旋转的弧线中产生，并界定出一个“图形”；（ii）该动态轮廓不仅能保护这个图形的封闭区域免受运动造成的破坏，还会中断周围环境的连续性；（iii）动态轮廓通常被视为组织成圆盘状，呈现为一种非模态完整形式，使得一个物体隐藏在另一个物体后面。椭圆形或轮廓图形很少产生动态轮廓这一事实被认为是由于图形自身的自足性，即不需要通过运动来实现感知上的完整。
