Recent studies have examined linguistic abilities in apes. However, although human mathematical abilities seem to be derived from the same foundation as those in language, we have little evidence for mathematical abilities in apes (but for exceptions see refs 7-10). In the present study, a 5-yr-old female chimpanzee (Pan troglodytes), 'Ai', was trained to use Arabic numerals to name the number of items in a display. Ai mastered numerical naming from one to six and was able to name the number, colour and object of 300 types of samples. Although no particular sequence of describing samples was required, the chimpanzee favoured two sequences (colour/object/number and object/colour/number). The present study demonstrates that the chimpanzee was able to describe the three attributes of the sample items and spontaneously organized the 'word order'.
最近的研究对猿类的语言能力进行了考察。然而，尽管人类的数学能力似乎与语言能力源自相同的基础，但我们几乎没有证据表明猿类具备数学能力（不过有一些例外情况，见参考文献7 - 10）。在本研究中，一只5岁的雌性黑猩猩“爱”（Pan troglodytes）接受训练，学会用阿拉伯数字说出展示物品的数量。“爱”掌握了从一到六的数字命名，并能够说出300种样本的数量、颜色和物品名称。虽然对描述样本并没有特定的顺序要求，但这只黑猩猩偏好两种顺序（颜色/物品/数字和物品/颜色/数字）。本研究表明，这只黑猩猩能够描述样本物品的三个属性，并自发地组织“词序”。
