Figure 6: Effects of education on number representations in Tsimane’ adults.
From: Universal and uniquely human factors in spontaneous number perception

Tsimane’ adults show an effect of education on the perception of number but not cumulative surface area. The beta weights were calculated from a mixed model logistic regression showing the effect of education on number and area weights in Tsimane' adults (n=51). Error bars represent the s.e. of the mean.
