Infants' visual processing of objects is characterised by a developmental trend from a predominantly analytical to a configural processing mode. In two studies with 6- and 8-month-old infants, we sought to replicate this finding in a purely visual condition (inspecting objects), and to examine how far redundant visual-haptic information present in a visual-haptic condition influences the processing mode. Infants were familiarized with two objects differing in three dimensions (texture, size and shape). At test, infants were presented with a familiar object, a switch object consisting of a recombination of familiar dimensions, and a novel object, and looking times were measured. Results indicate a transition from analytical processing at 6 months to configural processing at 8 months in the visual condition. In the visual-haptic condition, both age-groups displayed configural processing. Thus, redundant visual-haptic information seems to enhance object processing.
婴儿对物体的视觉加工具有一种发展趋势，即从主要的分析性加工模式转变为整体性加工模式。在两项针对6个月和8个月大婴儿的研究中，我们试图在纯粹的视觉条件下（检查物体）重现这一发现，并探究在视觉-触觉条件下存在的冗余视觉-触觉信息在多大程度上会影响加工模式。让婴儿熟悉两个在三个维度（质地、大小和形状）上不同的物体。在测试时，向婴儿呈现一个熟悉的物体、一个由熟悉维度重新组合而成的转换物体以及一个新物体，并测量他们的注视时间。结果表明，在视觉条件下，6个月大时为分析性加工，8个月大时转变为整体性加工。在视觉-触觉条件下，两个年龄组均表现出整体性加工。因此，冗余的视觉-触觉信息似乎会增强物体加工。
