A study by Martin Doherty from the Department of Psychology at the University of Stirling, shows that adults are fooled by something called the Ebbinghaus illusion but children aren't.

When gaging the size of an object, adults' brains take into account the context of things around the object but children don't. 

Understanding context develops slowly in children which is why they see the size of the object for what it really is!

So there you have it. Use your children to help you to see the truth but just make sure the cheeky monkeys don't fool you!
