Im doing a science project: Can body language help you determine if a person is lying?

This is my conclusion so far: In conclusion, my hypothesis that body language can, indeed, be a big help in determining whether or not a person is lying was proven correct. Despite the fact that no type of body language suggests ultimate proof of lying, I did background research on body language before experimenting, only to find that during my experiment, many of the surveyed students displayed at least one of these changes when they began to lie.


When a person lies, they’ll normally feel uncomfortable about it, and their displayed gestures will conflict with the words coming out of their mouths. Some people may give away their signs of lying without even realizing it. The body language of lying varies from the ever so tiny curling of the lip to excess and unnecessary laughing.





WHAT ELSE CAN I ADD?

You can add how some do not look the other in the face,, pupils dilate, play with their fingers, etc. and how detectives use subtle body language like this in their proffession to see if a suspect is lying or not.
Reply:I've heard that when faced with a question that a person may lie about - if they look left they're lying, if they look right they're trying to recall.. It's in the eyes
Reply:Touching the nose often indicates a lie. There are at least a couple of good books on body language. Your public library may have them.
Reply:You could suggest what research to do based on your research. Are there questions you would like answered which was brought up by your experiment?





Maybe you could describe how certian you think the experiment was.





What do you think is the importance of this finding?
