In this study I will present two different infants’ studies. First is glossiness perception in infants by using preferential looking paradigm (Yang et al, submitted). Their first experiment showed that the 7-8-month-olds, but not the 5-6 month-olds, significantly looked longer at the glossy object to the matte object. Their second experiment showed that the 7-8-month-old infants could discriminate between the glossy object and the textured object even though both had similar luminance histograms. On the other hand, the infants showed no discriminate for the textured object over the matte object even though they had largely different histograms. These findings suggest that 7-8-month-old infants perceive difference between glossy objects and matte objects on the basis of surface representations. Second is to explore the ability to generate spatial representations of an object as specified by static-pictorial depth cues by using a "transfer-across-depth-cues" method (Tsuruhara et al, 2009, 2010). 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. Six- to seven-month-old infants showed significant evidence of transfer from shading to surface contours and from shading to line-junctions, while four- to five-month-olds did not. This work supports the hypothesis that the ability to form 3D spatial representations from pictorial depth cues develops at about six months of age. |
