How this information is used to detect lies:
Example: Let’s say your child ask’s you for a cookie, and you ask them “well, what did your mother say?” As they reply “Mom said… yes.” they look to the left. This would indicate a made up answer as their eyes are showing a “constructed image or sound. Looking to the right would indicated a “remembered” voice or image, and thus would be telling the truth.
