Caption

To determine the ability to distinguish large and small quantities of objects, the Cantlon lab tested rhesus monkeys, adults and children in the United States, and adults of the Tsimane', a predominately "low numeracy" cultural group that inhabits an area of remote rain forest in Bolivia. This illustration from the study shows the images subjects were presented as part of the trial protocol. Each sample they viewed, for example, was a dot array, followed by two icons for categorizing the array as little (star) or a lot (diamond). Also shown are dot arrays varying in number of dots and the percentage of surface area they occupied.
