24名年龄在2到11周之间的婴儿对对称扩大的阴影做出反应，这些阴影在光学上指定了一个接近的物体，具有综合的回避反应和不安。不对称扩展阴影和指定未命中路径上的对象和后退对象的收缩阴影都不会发生此响应。无论年龄大小，在所有婴儿中都观察到了这种反应，并且向显示器添加动力学深度信息并没有增加反应的强度或可能性。在第二个实验中，七个婴儿对接近真实的物体做出防御性反应，除非它在一条错过的路径上。
Twenty-four infants ranging in age from 2 to 11 weeks responded to symmetrically expanding shadows, which optically specify an approaching object, with an integrated avoidance response and upset. This response did not occur for asymmetrically expanding shadows nor for contracting shadows that specify an object on a miss path and a receding object. The response was observed in all the infants regardless of age, and the addition of kinetic depth information to the displays did not increase the intensity or likelihood of the response. In a second experiment, seven infants defensively reacted to the approach of a real object except when it was on a miss path.
