Abstract
The purpose of this experiment was to study young children's capacity to predict the arrival of an approaching car.This was studied by means of filmscenes showing a child looking at an approaching car.The scenes are ended when the car is at a constant distance, but a time-code is still running.The subject is required to stop the time-code when he thinks that the car will pass the child. The following variables are varied in the film: the street shown, the type of car, and the speed at which the car approaches the child (slow, medium or fast). Three groups of each 24 subjects are used: children from grade ½, 4/5 and adults.
