一个“transfer-across-depth-cues”的方法被用来探索的能力的发展，产生和使用的空间表征的一个对象指定的静态图片的深度线索。婴儿习惯于一个物体的深度指定的一个线索，然后提出了相同的形状与深度指定的不同的线索。只有当那个物体的抽象表征形成时，才可能发生跨线索的迁移。阴影和线条连接点独特地决定了这些显示器中的3D形状，因此它们看起来要么是一块平顶蛋糕，要么是火箭。如果没有这些线索，两幅线条画都是一样的。6至7个月的婴儿表现出明显的转移证据，而4至5个月的婴儿则没有。一个对照实验表明，年幼的婴儿可以区分对象时，一个单一的深度线索指定的形状。这些结果与我们之前的研究结果相似，后者表明6至7个月大的婴儿表现出跨越阴影和表面轮廓线索的迁移，指定凸表面和凹表面（A。Tsuruhara，T. Sawada，S.金泽，M. K. Yamaguchi，& A. Yonas，2009）。这项工作支持的假设，形成3D空间表征的能力，从图片深度线索发展约6个月大。关键词：婴儿形状知觉，图画深度线索，明暗，线条连接，知觉发展
A "transfer-across-depth-cues" method was used to explore the development of the ability to generate and use spatial representations of an object as specified by static pictorial depth cues. Infants were habituated to an object with depth specified by one cue and then presented with the same shape with depth specified by a different cue. Only if an abstract representation of that object had been formed could transfer across cues occur. Shading and line junctions uniquely determined the 3D shapes in these displays so that they appeared to be either a slice of cake with a flat top or a rocket. Without these cues, both line drawings were identical. Infants aged 6 to 7 months showed significant evidence of transfer, while infants aged 4 to 5 months did not. A control experiment demonstrated that the younger infants could discriminate between the objects when a single depth cue specified the shapes. These results are similar to our previous findings, which indicated that 6- to 7-month-old infants show transfer across shading and surface-contour cues, specifying convex and concave surfaces (A. Tsuruhara, T. Sawada, S. Kanazawa, M. K. Yamaguchi, & A. Yonas, 2009). This work supports the hypothesis that the ability to form 3D spatial representations from pictorial depth cues develops at about 6 months of age.
