通常假设数字和空间的表示之间存在相互作用（例如，Dehaene，Bossini，& Giraux，1993;沃尔什，2003），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，空间方面不是固有的数字表示，而是空间和数字表示是分开的。然而，文化因素在他们之间建立了联系。通过扩展基于这一假设的早期模型（Gevers，Verguts，Rumvoet，Caessens，& Fias，2006; Verguts，Fias，& Stevens，2005），作者提出了计算机模拟，表明结合这一想法的模型可以解释一系列研究的数据。这些结果表明，数字空间的相互作用是由不同的大脑区域之间的相互作用产生的涌现特性。(C)2010年爱思唯尔公司All rights reserved.
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. (C) 2010 Elsevier Inc. All rights reserved.
