The mapping abilities of four-year-old children in York, England, Durban, South Africa, Tehran, Iran, Mexico City, Mexico and Evanston, Illinois, USA were investigated, using a methodology involving air-photo identification and simulated navigation on an air photo. The results show that essential mapping abilities (perspective and scale transformations) are well developed by the age of four in these cultures, and provide some evidence in support of the hypothesis that mapping abilities emerge without training in very young children of all cultures.  相似文献
