Abstract

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 specied by static pictorial depth cues. Infants were habituated to an object with depth specied by one cue and then presented with the same shape with depth specied 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 at top or a rocket. Without these cues, both line drawings were identical. Infants aged 6 to 7 months showed signicant 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 specied the shapes. These results are similar to our previous ndings, 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.
