One of the most fundamental achievements in infants' cognitive development is their appreciation that material objects exist permanently in space and time. Recent findings suggest that infants fail to identify fragmented material objects as continuously existing items. Four experiments assessed 8-12-month-old infants' ability to further represent an object that was fragmented into two or more parts. Results suggest that infants successfully trace the spatiotemporal displacement of fragmented objects, but that their processing of size/quantity-related property information may be affected. This suggests that, contrary to recent claims, 8- to 12-month-old infants can and do appreciate the continuity of fragmented objects.
婴儿认知发展中最基本的成就之一是他们认识到物质对象在空间和时间中永久存在。最近的研究结果表明，婴儿无法将碎片化的物质对象识别为连续存在的物品。四项实验评估了 8-12 个月大的婴儿进一步代表被分成两个或更多部分的物体的能力。结果表明，婴儿成功地追踪了碎片化物体的时空位移，但他们对大小/数量相关属性信息的处理可能受到影响。这表明，与最近的观点相反，8 至 12 个月大的婴儿能够并且确实理解碎片化物体的连续性。
