Numerical cognition might be embodied, that is, grounded in bodily actions. This claim is supported by the observation that, potentially due to our shared biology, finger counting is prevalent among a variety of cultures. Differences in finger counting are apparent even within Western cultures. Relatively few indigenous cultures have been systematically analyzed in terms of traditional finger counting and montring (i.e., communicating numbers with fingers) routines. Even fewer studies used the same protocols across cultures, allowing for a systematic comparison of indigenous and Western finger counting routines. We analyze the finger counting and montring routines of Tsimane' (N = 121), an indigenous people living in the Bolivian Amazon rainforest, depending on handedness, education level, and exposure to mainstream, industrialized Bolivian culture. Tsimane' routines are compared with those of German and British participants. Tsimane' reveal a greater variation in finger counting and montring routines, which seems to be modified by their education level. We outline a framework on how different factors such as handedness and reading direction might affect cross-cultural and within-cultural variation in finger counting.
数值认知可能是具体的，也就是说，基于身体动作。这一说法得到了以下观察结果的支持：由于我们具有共同的生物学基础，手指计数在各种文化中都很普遍。即使在西方文化中，手指计数的差异也很明显。相对较少的土著文化在传统的手指计数和用手指表示数字（即 montring）的常规方面得到了系统的分析。使用相同的方案在不同文化中进行比较的研究就更少了，这使得对土著和西方的手指计数常规进行系统比较成为可能。我们分析了生活在玻利维亚亚马逊雨林中的提斯曼人（N=121）的手指计数和 montring 常规，这些常规取决于惯用手、教育水平以及接触主流、工业化玻利维亚文化的程度。提斯曼人的常规与德国和英国参与者的常规进行了比较。提斯曼人在手指计数和 montring 常规方面表现出更大的差异，这似乎是由他们的教育水平所改变的。我们概述了一个框架，说明惯用手和阅读方向等不同因素如何影响手指计数的跨文化和文化内差异。
