对数字的记忆会随着年龄和经验的增长而提高。改进的一个潜在来源是儿童对大小的表示从对数到线性的转变。为了测试这一点，幼儿园学生和二年级学生估计了数字在数轴上的位置，并回忆了小插图中呈现的数字（研究 1）。在控制了年龄的影响和近似数量级的能力（映射器状态）后，数轴估计的准确性预测了数字回忆任务的记忆准确性。为了更直接地测试线性数值幅度表示是否会提高记忆力，一半的儿童获得了关于他们的数轴估计的反馈（研究 2）。正如预期的那样，即使在控制了年龄和制图者状态之后，学习线性表示再次与数字信息的记忆联系起来。这些结果表明，数字幅度的线性表示可能是数字回忆准确性发展的一个因果因素。
Memory for numbers improves with age and experience. One potential source of improvement is a logarithmic-to-linear shift in children’s representations of magnitude. To test this, Kindergartners and second graders estimated the location of numbers on number lines and recalled numbers presented in vignettes (Study 1). Accuracy at number-line estimation predicted memory accuracy on a numerical recall task after controlling for the effect of age and ability to approximately order magnitudes (mapper status). To test more directly whether linear numeric magnitude representations caused improvements in memory, half of children were given feedback on their number-line estimates (Study 2). As expected, learning linear representations was again linked to memory for numerical information even after controlling for age and mapper status. These results suggest that linear representations of numerical magnitude may be a causal factor in development of numeric recall accuracy.
