虽然4个月大的婴儿通过遮挡感知物体轨迹的连续性，但对这个年龄段指定遮挡表面的信息知之甚少。我们在涉及84名参与者的3个实验中对此进行了研究。测试声称，5个月大的婴儿无法感知Kanizsa图形作为一个闭塞的表面（Csibra，2001），我们证明，4个月大的婴儿认为轨迹连续性背后的这个数字提供其水平范围很小。我们证明了可见的遮挡边缘或背景遮挡的存在不足以指定遮挡表面，但它们的组合是足够的。因此，除了物体的删除和增生，可见的遮挡边缘和背景的遮挡对于这个年龄段的遮挡表面的感知是必要的。
Although 4-month-olds perceive continuity of an object's trajectory through occlusion, little is known about the information specifying an occluding surface at this age. We investigated this in 3 experiments involving 84 participants. Testing the claim that 5-month-olds are unable to perceive the Kanizsa figure as an occluding surface (Csibra, 2001), we demonstrated that 4-month-olds perceived trajectory continuity behind this figure providing its horizontal extent was small. We demonstrated that the presence of visible occluding edges or occlusion of background was insufficient to specify an occluding surface but that their combination was sufficient. Thus, beyond object deletion and accretion, both visible occluding edges and occlusion of background are necessary for perception of occluding surfaces at this age.
