Abstract：
Mapping numbers onto space is a common cognitive representation that has been explored in both behavioral and neuroimaging contexts. Empirical work probing the diverse nature of these spatial-numerical associations (SNAs) has led researchers to question 1) how the human brain links numbers with space, and 2) whether this link is biologically vs. culturally determined. We review the existing literature on the development of SNAs and situate that empirical work within cognitive and neuroscientific theoretical frameworks. We propose that an evolutionarily-ancient frontal-parietal circuit broadly tuned to multiple magnitude dimensions provides the phylogenetic substrate for SNAs, while enculturation and sensorimotor experience shape their specific profiles. We then use this perspective to discuss educational implications and highlight promising avenues for future research.
摘要：
将数字映射到空间是一种常见的认知表示，已在行为和神经影像学背景下进行了探索。探索这些空间-数字关联（SNA）的多样性的经验工作导致研究人员质疑1）人脑如何将数字与空间联系起来，和2)此链接是否在生物学上与文化决定。我们回顾了有关SNA发展的现有文献，并将该实证工作置于认知和神经科学理论框架内。我们建议将进化上古老的额叶-顶叶回路广泛调整到多个幅度维度，为SNA提供了系统发育基础，而充实和感觉运动体验塑造了它们的特定轮廓。然后，我们使用这个观点来讨论教育意义，并强调未来研究的有希望的途径。
