我们研究了光泽知觉婴儿使用优先寻找范式。在实验1中，两个娃娃形状的物体的图像与磨砂和光泽的表面呈现给婴儿年龄5至6个月和7至8个月。结果显示，7到8个月奥尔兹，而不是5到6个月奥尔兹的婴儿，在光滑的物体上看的时间明显长于无光泽的物体。在实验2中，我们还采用了一个对象，这是哑光和覆盖有纹理的白色油漆飞溅，其亮度直方图几乎是相同的光泽对象。结果表明，7 - 8个月大的婴儿可以区分有光泽的物体和有纹理的物体，即使两者具有相似的亮度直方图。对于不包含面部特征的简单球体，获得了定性相似的结果。因此，实验1和2的结果不是由于娃娃面部特征的可见性差异。这些结果表明，7至8个月大的婴儿感知光滑物体和无光泽物体的表面表征的基础上的差异。
We examined glossiness perception in infants using a preferential looking paradigm. In experiment 1, the images of two doll-shaped objects with matte and glossy surfaces were presented to infants aged 5 to 6 and 7 to 8 months. The results showed that the 7 to 8 month olds, but not the 5 to 6 month olds, looked significantly longer at the glossy object than at the matte object. In experiment 2, we additionally employed an object that was matte and covered with textures of white paint splashes, whose luminance histogram was almost identical to that of the glossy object. The results showed that the 7 to 8 month old infants could discriminate between the glossy object and the textured object even though both had similar luminance histograms. Qualitatively similar results were obtained for simple spheres that did not contain facial features. Therefore, the results of experiments 1 and 2 were not due to differences in the visibility of the dolls' facial features. These findings suggest that 7 to 8 month old infants perceive difference between glossy objects and matte objects on the basis of surface representations.
