一些实证研究表明，6-7个月以下的婴儿无法从他们的环境中提取静态单眼深度信息。本研究的目的是通过使用弯曲Y结表示的三维结构来扩展这些发现。5个月和8个月大的婴儿习惯于画圆柱体的线条。在测试过程中，婴儿们观看了两种显示，其中一种是习惯性图形的表面标记被删除，另一种是边缘被删除。方差分析显示，1个月大的受试者在缺乏边缘的不适应显示上看的时间明显更长，而5个月大的受试者则没有。研究结果证明，8个月大的婴儿能够区分表示边缘的线条和表示标记的线条，并且他们能够使用线的连接点来感知画在画面平面上的三维物体的线条。(C) 1999学术出版社。
Several empirical studies demonstrate that infants under 6-7 months of age are unable to extract static-monocular depth information from their environment. The aim of this study was to extend these findings by using a three-dimensional structure indicated by curved Y junctions. Infants 5 and 8 months of age were habituated to the line drawing of a cylinder. During test trials, the infants viewed two displays, one in which a surface marking had been deleted from the habituation figure and one in which an edge had been erased. An ANOVA revealed that the I-month-ord subjects looked significantly longer at the dishabituation display lacking the edge, whereas the 5-month-olds did not. The results provide evidence that 8-month-old infants distinguish between lines indicating edges and lines indicating markings and that they are able to use line junctions to perceive line drawings as depictions of three-dimensional objects in the picture plane.
