Child's play

GPS World, March, 2008

Researchers at the University of Bristol have shown that GPS can be used to demonstrate how children as young as three find their way around, reports vnunet.com. Previous research has suggested that humans don't use landmarks to orient themselves until about age six, but those studies took place in artificial lab environments.

Using GPS to track children in a park as they searched for prizes, researchers found that children as young as three use outdoor landmarks, like trees and buildings, to find their way around.
