16周大的婴儿能够区分由自身运动产生的光位移和由运动物体产生的光位移，并且他们只使用后者来感知部分遮挡物体的统一性。在静止物体周围移动观察者所产生的光学变化所产生的注意力水平，与静止观察者观看静止显示器的特征相同，远低于静止观察者观看移动显示器所显示的注意力水平。通过移动物体以保持与移动观察者的恒定关系而产生的没有主体相对位移的物体的真实位移，引起的注意水平比静止的显示器更高，并且更具有对移动显示器的注意特征，这一发现表明检测到真实的运动。先前的报道发现，婴儿从运动信息中感知部分遮挡物体的统一性的能力依赖于真实物体的运动，而不是一般的光学位移。结果表明，物体感知依赖于三维布局中表面运动的配准。
Sixteen-week-old human infants distinguish optical displacements given by their own motion from displacements given by moving objects, and they use only the latter to perceive the unity of partly occluded objects. Optical changes produced by moving the observer around a stationary object produced attentional levels characteristic of stationary observers viewing stationary displays and much lower than those shown by stationary observers viewing moving displays. Real displacements of an object with no subject-relative displacement, produced by moving an object so as to maintain a constant relation to the moving observer, evoked attentional levels that were higher than with stationary displays and more characteristic of attention to moving displays, a finding suggesting detection of the real motion. Previously reported abilities of infants to perceive the unity of partly occluded objects from motion information were found to depend on real object motion rather than on optical displacements in general. The results suggest that object perception depends on registration of the motions of surfaces in the three-dimensional layout.
