It is commonly assumed that there is an interaction between the representations of number and space (e.g., Dehaene, Bossini, & Giraux, 1993; Walsh, 2003), typically ascribed to a mental number line. The exact nature of this interaction has remained elusive, however. Here we propose that spatial aspects are not inherent to number representations, but that instead spatial and numerical representations are separate. However, cultural factors establish ties between them. By extending earlier models (Gevers, Verguts, Reynvoet, Caessens, & Fias, 2006; Verguts, Fias, & Stevens, 2005) based on this hypothesis, the authors present computer simulations showing that a model incorporating this idea can account for data from a series of studies. These results suggest that number-space interactions are emergent properties resulting from the interaction between different brain areas.
人们通常认为数字和空间的表示之间存在相互作用（例如，Dehaene、Bossini 和 Giraux，1993；Walsh，2003），通常归因于心理数字线。然而，这种相互作用的确切性质仍然难以捉摸。在这里，我们提出空间方面并不是数字表示的固有特征，而是空间和数字表示是分开的。但是，文化因素将它们联系在一起。通过扩展基于该假设的早期模型（Gevers、Verguts、Reynvoet、Caessens 和 Fias，2006；Verguts、Fias 和 Stevens，2005），作者提出了计算机模拟，表明纳入该想法的模型可以解释一系列研究的数据。这些结果表明，数字-空间相互作用是不同大脑区域相互作用产生的新兴特性。
