Narrator: Parents, listen up – just watching your child's body language may not be enough to determine whether or not they are telling the truth. This is Science Today. A new study by psychologist Kang Lee of the University of California, San Diego found that when it comes to kids, even police officers are often wrong when looking to body language as an indicator of truth telling.
Lee: You must have heard when a person lies the person they try to avoid eye contact. The person appear fidgeting and nervous and this and that. It turns out these things are not true, including kids as young as three years of age when they lie they look right into your eyes.
Narrator: So, Lee warns that the old adage of watching for nonverbal cues can be misleading – especially when it comes to children.
Lee: You have to accept the fact that children will lie and number two, that they lie very well. In particular, they can manage their body language and their facial expressions very well. So you cannot rely on the cues to detect there lies.
