处理文物是无处不在的人类技术，但如何年幼的孩子从事空间协调的行为与这些文物还没有得到很好的理解。为了解决这一问题，使用运动跟踪技术对17-36个月的儿童（N = 30）进行了研究，因为他们将手柄伪影的远端节段放入槽中。手柄与远端节段正交。结果显示，在前瞻性控制的发展差异与工件的空间结构。尽管所有儿童都完成了装配，但年龄较小的儿童首先定向手柄，然后是远端节段（并且仅在远端节段接触槽之后），而3岁的儿童在远端节段接触槽之前，在不同的空间平面中同时定向手柄和远端节段。事实证明，选择一个有效的抓握姿势对所有孩子来说都很困难。结果进行了讨论，在儿童如何开始涉及到他们的行动的三维空间结构的处理对象和前瞻性的控制对象的运动在多个空间平面。
Handled artifacts are ubiquitous in human technology, but how young children engage in spatially coordinated behaviors with these artifacts is not well understood. To address this issue, children (N = 30) from 17-36 months were studied with motion tracking technology as they fit the distal segment of a handled artifact into a slot. The handle was orthogonal to the distal segment. Results revealed developmental differences in prospective control tied to the artifact's spatial structure. Although all children accomplished fitting, younger children first oriented the handle and then the distal segment (and only after the distal segment contacted the slot), whereas children by 3 years of age oriented the handle and distal segment simultaneously in different spatial planes, prior to the distal segment contacting the slot. Choosing an effective grip posture proved difficult for all children. Results are discussed in terms of how children begin to relate their actions to the 3-dimensional spatial structure of handled objects and the prospective control of object movement in multiple spatial planes.
