Pre-school children and the traffic light task.

An experiment was conducted to determine whether preschool kindergarten children are capable of learning a simulated traffic light task. It was found that some children under three years of age learnt to perform the task, and many of them made no errors. Although performance improved with age, it was concluded that if a child is mature enough to be accepted at preschool kindergarten, he is likely to be able to learn the simulated traffic light task.
