两个实验考察了5个月大的婴儿对以触觉和视觉模式呈现的一组物体之间的数字对应关系的敏感性。实验采用了一种经典的从触觉到视觉的跨通道迁移任务。婴儿首先熟悉右手中一个接一个呈现的两到三个不同的物体。然后，向他们展示包含两到三个物体的可视显示器。视觉展示依次呈现(实验1)或同时呈现(实验2)。在这两个实验中，结果表明，婴儿看视觉显示器的时间更长，其中包含的物体数量与触觉熟悉阶段不同。综上所述，结果表明，婴儿能够检测到触觉和视觉刺激序列之间的数字对应，并加强了5月龄婴儿对少数物体(两个或三个)跨感觉通道的非固定和抽象表征的假说。(C)2006 Elsevier Inc.保留所有权利。
Two experiments investigated 5-month-old infants' amodal sensitivity to numerical correspondences between sets of objects presented in the tactile and visual modes. A classical cross-modal transfer task from touch to vision was adopted. Infants were first tactually familiarized with two or three different objects presented one by one in their right hand. Then, they were presented with visual displays containing two or three objects. Visual displays were presented successively (Experiment 1) or simultaneously (Experiment 2). In both experiments, results showed that infants looked longer at the visual display which contained a different number of objects from the tactile familiarization phase. Taken together, the results revealed that infants can detect numerical correspondences between a sequence of tactile and visual stimulation, and they strengthen the hypothesis of amodal and abstract representation of small numbers of objects (two or three) across sensory modalities in 5-month-old infants.
