It seems so simple: you look both ways and calculate the time it will take to cross the street without getting hit. But according to this study, children under a certain age lack the perceptual judgment and motor skills to make this assessment.
“Some people think younger children may be able to perform like adults when crossing the street,” said Jodie Plumert, professor in the University of Iowa’s Department of Psychological and Brain Sciences. “Our study shows that’s not necessarily the case on busy roads where traffic doesn’t stop.”
