Studies examined infants' perceptions of 3-dimensional form, using a kinetic depth effect (KDE) display and displays containing subsets of the motion present in the KDE display. One subset consisted of "between-contour" motion, and the second consisted of "within-contour" motion. Research with adults has suggested that only between-contour motion leads to a compelling depth percept. In Experiments 1 and 2, infants generalized habituation from a KDE display to the between-contour but not the within-contour changes. In Experiments 3 and 4, infants generalized habituation from a KDE display to the between-contour display viewed from a novel orientation but not to the within-contour display viewed from the original orientation. Results indicate sensitivity to between-contour but not within-contour information, suggesting that infants perceive the 3-dimensional form of these displays.
研究使用动态深度效应（KDE）显示器以及包含KDE显示器中部分运动的显示器，考察了婴儿对三维形状的感知。其中一个子集由“轮廓间”运动组成，另一个子集由“轮廓内”运动组成。针对成年人的研究表明，只有轮廓间运动才会产生令人信服的深度感知。在实验1和实验2中，婴儿将习惯化从KDE显示器推广到轮廓间变化，而非轮廓内变化。在实验3和实验4中，婴儿将习惯化从KDE显示器推广到以新方向观看的轮廓间显示器，但不会推广到以原始方向观看的轮廓内显示器。结果表明婴儿对轮廓间信息敏感，而对轮廓内信息不敏感，这表明婴儿能够感知这些显示器的三维形状。
