At first glance, can you tell in which direction the bus is moving?
A puzzle asking students to determine which direction a bus is traveling is leaving some adults flummoxed.
National Geographic has produced its own version of the popular brainteaser displaying a yellow bus with matching windows at either end. Because the image gives no glimpse of a front hood or other distinguishing characteristics, the viewer has no idea which is the front and which is the back.
When National Geographic quizzed some kids using the brainteaser in its Brain Games TV series, 80 percent of children under 10 got it right, according to Daily Mail.
The brainteaser is not new, but has resurfaced after being shared on social media.
The correct answer is that the bus is traveling to the left. But if you’re in the U.K. or any other country that drives on the left side of the road, the opposite is true.
The key to solving the puzzle is in the passenger doors -- or lack thereof. Because the picture does not show any doors, that means they must be on the other side.
Adults are said to have a harder time identifying the direction of the bus than children, but there’s no definitive data proving it.
It’s been theorized that children fare better at using visual clues and previous experience to translate a picture of situation.
Research from University College London and Birkbeck, University of London discovered that kids under 12 observe visual information differently from adults, according to Metro.
Children have a tendency to use the first visual cue their brain processes when forming judgments, making them less precise but much quicker.
On the other hand, Adults use various kinds of visual information in addition to sensory cues when coming to a conclusion.
