When the team examined the results of the experiment more closely, they noticed that the monkeys tended tounderestimate(低估)a sum compared with a single symbol when the two were close in value - sometimes choosing, for example, a 13 over the sum of 8 and 6.
当研究小组更加深入地检测试验结果的时候, 他们注意到, 当两个符号在数值上接近的时候, 猴子们倾向于低估总和——例如, 有时猴子认为13大于8和6的总和。
