时间、空间和数字的表征在灵长类动物的认知系统中是严格联系在一起的。在这里，我们表明，仅仅观察数字符号会对它们的持续时间产生偏见，这取决于数字的大小。在第一个实验中，一组健康的受试者被要求完成一项时间估计任务，要求判断测试刺激的持续时间比先前参考固定刺激(数字5；持续时间300ms)的持续时间更长还是更短。测试刺激为数字1、5和9，范围在250到350毫秒之间。主要结果表明，时间知觉根据数字表示的大小存在偏差：低数字(即1)导致低估，高数字(即9)高估感知持续时间。对照实验表明，无论测试什么数字，这一结果都是一致的，但如果使用字母表，则不是这样。这些发现论证了认知系统中时间和数字之间的功能交互作用。(C)2008爱思唯尔爱尔兰有限公司。保留所有权利。
The representation of time, space and numbers are strictly linked in the primate's cognitive system. Here we show that merely looking at number symbols biases a temporal judgment on their duration depending upon the number's magnitude. In a first experiment, a group of healthy subjects was submitted to a time estimation task, requiring to judge whether the duration of a test stimulus was longer or shorter than that of a previous reference fixed stimulus (digit 5; duration 300 ms). Test stimuli were the digits 1, 5 and 9 ranging between 250 and 350 ms. The main results showed that temporal perception was biased according to the magnitude expressed by the digit: low digits (i.e. 1) leading to underestimation and high digits (i.e. 9) an overestimation of perceived duration. Control experiments showed that this result was consistent whatever digits were tested but not when letters of the alphabet were used. These findings argue for a functional interaction between time and numbers in the cognitive system. (c) 2008 Elsevier Ireland Ltd. All rights reserved.
