近年来，手指计数和数字加工之间存在很强的函数关系。发展研究表明，个体手指计数系统的结构对算术能力有特定的影响。此外，心理数量表征（“数轴”）的方向似乎受到手指计数习惯的影响。然而，目前尚不清楚手指计数系统的结构是否仍然影响着受过教育的成年人对符号数的处理。在目前的跨文化研究中，我们通过对三组不同参与者（德国聋人手语者、德国和中国听力正常的成年人）的阿拉伯数字比较任务中基于手指的亚五进制效应进行了研究，来探讨这个问题。我们在所有的小组中都观察到五次进制的影响，但在德国的两个小组中尤其如此，他们在手指计数习惯中使用了明确的五次进制系统。结论是，即使在成年人中，身体体验——即数手指——也会影响抽象心理数字表征的结构。因此，目前的研究结果支持了一个普遍的观点，即即使是看似抽象的认知，也可能至少部分植根于我们的身体体验。(C) 2010 Elsevier B.V.版权所有
In recent years, a strong functional relationship between finger counting and number processing has been suggested. Developmental studies have shown specific effects of the structure of the individual finger counting system on arithmetic abilities. Moreover, the orientation of the mental quantity representation ("number line") seems to be influenced by finger counting habits. However, it is unclear whether the structure of finger counting systems still influences symbolic number processing in educated adults.In the present transcultural study, we pursued this question by examining finger-based sub-base-five effects in an Arabic number comparison task with three different groups of participants (German deaf signers, German and Chinese hearing adults). We observed sub-base-five effects in all groups, but particularly so for both German groups who use an explicit sub-base-five system in their finger counting habits. It is concluded that bodily experiences - namely finger counting - influence the structure of the abstract mental number representations even in adults. Thus, the present findings support the general idea that even seemingly abstract cognition may at least partially be rooted in our bodily experiences. (C) 2010 Elsevier B.V. All rights reserved.
