本研究的目的是发现是否有联运的形状从触摸到视觉，反之亦然，在2至3个月大的婴儿谁还没有达到视觉指定的对象。在第一个实验中，习惯化程序用于每种模式，两个样本的32名儿童。在触觉和视觉模式中发现了习惯化和歧视，这两种模式的总探索时间是相同的。在第二个实验中，让32名儿童以视觉或触觉的方式熟悉一个物体，然后使用（1）相同或（2）不同的物体进行两次测试。如果转移确实发生，则在新模式中呈现的熟悉对象的探索时间应该小于在新模式中呈现的新对象所需的探索时间。此外，当熟悉的物体以熟悉的模式呈现给婴儿时，婴儿应该识别出熟悉的物体。此外，模态内辨别应发生在不同模态的连续呈现之后。发生了从触觉到视觉的联运转移，但没有发生从视觉到触觉的联运转移。与在4/5个月大的儿童中获得的数据进行比较，为讨论这些发现提供了基础。
The aim of this study is to discover whether there is intermodal transfer of shape from touch to vision and vice versa in 2- to 3-month-old infants who are not yet capable of reaching out to visually specified objects. In the first experiment, a habituation procedure was used for each mode, with two samples of 32 children. Habituation and discrimination were found in the tactile and visual modes, and total exploration time was identical for the two modes. In the second experiment, the 32 children were made familiar with an object in either the visual or the tactile mode, and then two tests were carried out using (1) the same or (2) a different object. If transfer does occur, exploration time for the familiar object presented in the new mode should be less than that required for a new object presented in the new mode. Also, the infants should recognize the familiar object when it is presented to them in the familiar mode. In addition, intramodal discrimination should occur after successive presentations in different modes. Intermodal transfer from touch to vision but not from vision to touch did occur. Comparison with data obtained in 4/5-month-old children provides the basis for discussion of these findings.
