虽然在第一年期间，人们对物体操纵的发展有了相当多的了解，但对婴儿如何手动探索物体表面以及如何将物体与表面联系起来的了解较少。为了解决这些问题，60名婴儿(分别为6、8和10个月大的20名)被展示在桌面上硬的和软的物体上，这些物体的材料特性各不相同。桌面表面要么是液体的，要么是不连续的，要么是柔性的，要么是刚性的。结果表明，婴儿有选择地探索物体、表面及其相互作用，根据物体或表面的材料属性定制他们的手动操作。在某些情况下，选择性随着年龄的增长而增加。这些发现对于理解问题解决和工具使用的起源具有重要意义。
Although a considerable amount is known about the development of object manipulation during the 1st year, less is known about how infants manually explore surfaces and relate objects to surfaces. To address these issues, 60 infants (20 each at 6, 8, and 10 months of age) were presented hard and soft objects on tabletop surfaces, which varied in terms of their material properties. Tabletop surfaces were either liquid, discontinuous, flexible, or rigid. Results indicated that infants explored the objects, surfaces, and their interactions selectively, tailoring their manual actions to the material properties of the objects or surfaces. In some instances, selectivity increased with age. The implications of these findings for understanding the origins of problem solving and tool use are considered.
