Watch: Can you tell if your child is lying?

'And we found that those young children who have more advanced mind-reading and self-control abilities tell lies earlier and are more sophisticated liars. As it turns out, these two abilities are also essential for all of us to function well in our society.' It's not easy to tell when kids lie, but behind that neutral mask, 'the child is actually experiencing a lot of emotions, such as fear, guilt, shame and maybe a little bit of liar's delight.' Here are some figures as well, to think about. Lee shares, 'We found that regardless of gender, country, religion, at two years of age, 30 percent lie, 70 percent tell the truth about their transgression. At three years of age, 50 percent lie and 50 percent tell the truth. At four years of age, more than 80 percent lie. And after four years of age, most children lie. So as you can see, lying is really a typical part of development. And some children begin to tell lies as young as two years of age.'
