两项实验测试了 4 岁和 8 岁儿童对目标销钉的范围进行编码以及随后区分目标和具有新颖范围的箔片的能力。通过操纵提供刺激的容器的高度，我们测试了孩子们是否使用销钉和容器之间的关系来编码范围。我们发现 8 岁的孩子不依赖于目标销钉和容器之间的关系来编码范围，但 4 岁的孩子只编码目标销钉相对于容器的范围。这种早期相对于一致标准对范围进行编码的能力可以作为发展测量能力的感知基础。
Two experiments tested the ability of 4- and 8-year-old children to encode the extent of a target dowel and later discriminate between the target and a foil having a novel extent. By manipulating the heights of containers in which we presented the stimuli we tested whether children used the relation between the dowels and containers for encoding extent. We found that 8-year-olds encoded extent without relying on the relation between the target dowel and container but 4-year-olds only encoded the extent of the target dowel relative to the container. This early ability to encode extent relative to an aligned standard may serve as a perceptual basis for the developing ability to measure.
