This is a very interesting topic that has I had thought about for a long time. Well, according to research and statistics,lying is a skill all children learn. It is a tool for avoiding blame or punishment, and for shoring up a poor self-image. While all children lie, some do it much more than others. Psychologists who study lying have found patterns that help predict which children will lie the most.

The most common reasons for lying, particularly among younger children, is a fear of punishment. This is especially true when the punishment is severe or the parents have unrealistically high expectations for their children.

For older children, chronic lying is often a rebellion against restrictions. It is a way to challenge a parent's authority. Preteens no longer feel they must tell their parents everything they do; they may respond with a lie to what they perceive as an intrusive question.

As they grow older, children realize that the greatest control they can have is the control of information. Generally, the more intrusive or overinvolved parents are, the more likely it is that preadolescents will lie by omitting information. Often they do this blatantly, as if to emphasize their growing need for privacy. "Where did you go?" "Nowhere." What did you do?" "Nothing." "Who was there?" "Nobody you'd know."

A sudden increase in lying can also be a signal that something's wrong in the family. This is especially true if the child is acting out in other ways, such as stealing or committing vandalism. You should pay particular attention if the victims of the thefts or other petty crimes are other family members. Often this is a cry for help that is much louder than his words alone could be.
