In this article, the authors explored the existence of across-notation automatic numerical processing using size comparison and same-different paradigms. Participants were Arabic speakers, who used 2 sets of numerical symbols -- Arabic and Indian. They were presented with number pairs in the same notation (Arabic or Indian) or in different ones (Arabic and Indian). In the size comparison paradigm, 2 digits differing both numerically and physically were compared on the physical dimension. Nevertheless, there was evidence that participants automatically processed the irrelevant numerical dimension in different notation pairs. In the same-different paradigm, 2 digits were presented either in the same or in different notations. Participants had to indicate whether the 2 digits were physically the same. The results again showed evidence for the automatic processing of numerical magnitude for pairs in different notations. Findings of both experiments suggest that numbers in different notations are automatically translated into a common representation of magnitude, in line with M. McCloskey's (1992) abstract representation model.
在本文中，作者使用大小比较和异同范式探究了跨符号自动数字处理的存在情况。参与者为说阿拉伯语的人，他们使用两组数字符号——阿拉伯数字和印度数字。向他们呈现相同符号（阿拉伯数字或印度数字）或不同符号（阿拉伯数字和印度数字）的数字对。在大小比较范式中，对在数值和物理上都不同的两个数字在物理维度上进行比较。然而，有证据表明参与者会自动处理不同符号对中不相关的数字维度。在异同范式中，以相同或不同符号呈现两个数字。参与者必须指出这两个数字在物理上是否相同。结果再次显示出对不同符号数字对进行数字大小自动处理的证据。两个实验的结果表明，不同符号的数字会自动转换为一个共同的大小表征，这与M. 麦克洛斯基（1992）的抽象表征模型一致。
