The mapping abilities of four-year-old children in York, England, Durb
an, South Africa, Tehran, Iran, Mexico City, Mexico and Evanston, Illi
nois, USA were investigated, using a methodology involving air-photo i
dentification and simulated navigation on an air photo. The results sh
ow that essential mapping abilities (perspective and scale transformat
ions) are well developed by the age of four in these cultures, and pro
vide some evidence in support of the hypothesis that mapping abilities
emerge without training in very young children of all cultures.
