很多动物可以利用数量信息。但是关于动物对数量信息的利用方式有2种看法:
1. 动物仅仅在迫不得已时才利用数量信息,它们会首先选用颜色、形状等信息
2. 动物总是会自发地利用数量信息了解周围环境。
研究者利用猕猴进行了一项测试,”匹配任务“。但是这次的测试有多个正确答案,比无论颜色匹配正确、形状匹配正确还是数量匹配争取都可以获得奖励。
令人吃惊的是,所有猕猴会首先选择数量比例作为匹配任务的决策依据。

How Much Does Number Matter to a Monkey (Macaca mulatta)?
a slick online interface for browsing multi-facetted data structures, such as the collection of past Nobel price prize winners. the "elastic list" concept enhances traditional facet browsing by visualizing relative proportions (weights) of metadata values by size or brightness, & by using animated filtering transitions.
for instance, a brighter background indicates a higher weight of a specific metadata value compared to the overall distribution, such as "Switzerland" & "female" for the winners of the Nobel Peace price. users can also investigate little sparkline diagrams to explore the temporal distribution of each metadata value over time.
