A second group of volunteers was then asked to watch the films and try to detect the lies by watching the eye movements. Prof Wiseman, a psychologist from the University of Hertfordshire, said: "The results of the first study revealed no relationship between lying and eye movements, and the second showed that telling people about the claims made by NLP practitioners did not improve their lie detection skills. A follow-up study involving analysing videos of high-profile press conferences in which people appealed for help in finding missing relatives, or claimed to have been themselves the victims of crime.
While some were telling the truth, others turned out to be lying. There was no evidence of a correlation between lying and eye movements. Co-author Dr Caroline Watt, from the University of Edinburgh, said: "A large percentage of the public believes that certain eye movements are a sign of lying, and this idea is even taught in organisational training courses.

Bouton says exceptions to the usual blink rate mostly have to do with production of dopamine in the body. For example, a person with Parkinson's disease will have a noticeably slower blink rate than what is usual, while a person with schizophrenia will blink more rapidly than normal.
Bouton says that when a person closes his eyes for a second or two, this may indicate he's lied to you, since this is a type of defense mechanism. Normally, he explains, a person will blink at a speed of to milliseconds, or 0. Bouton says sweat may appear on the forehead, cheeks, or back of the neck, and you'll likely observe the person try to wipe it away. Blushing is an involuntary reflex caused by sympathetic nervous system this activates your fight-or-flight response and is a response to the release of adrenaline.
Often when people tell the truth they will nod their heads simultaneously in agreement with what they're saying.

If however, you see this when you are speaking to someone, it may mean they think you are lying. Open palms are a traditional sign of honesty, with palms facing upwards it shows the person has nothing to hide. This stems from when two people would show their palms on meeting, to show they weren't hiding any weapons.
People generally find it difficult to lie with open palms and if they try, it will look contrived. The professional scam-artist will have learned to do this convincingly, to help him charm people into parting with their cash. When someone is telling you a lie, they will often find it difficult to look you directly in the eye. To avoid eye contact they may rub their eyes. Men will rub their eyes briskly or look down when lying. Women are more likely to rub below their eyes or stare up whilst lying.
Prolonged eye contact may also be a clue to a lie. The liar may overcompensate because he knows a lack of eye contact can look suspicious. As with other possible symptoms this should be taken in context with other behaviour. If you watch someone's eyes carefully you get clues to the way they are thinking. This can only be used as a general rule of thumb because everyone thinks in a different way so this won't apply to everybody.
In my experience this does work most of the time, but you have to think carefully about what the person's thought process is when the eye movement takes place. When someone looks up and to the left from your point of view their right they are constructing an image, in other words they are making up a situation in their mind, clearly this could mean they are lying.
If they look left but their eye's stay level they are constructing a sound, for example they could be imagining a conversation that they haven't had. When they look up and to the right they are remembering an image probably not lying and when they look right but keep their eye's level they are remembering a sound. If someone looks down and to the left they are accessing their feelings and when they look down and to the right they are having an internal dialogue with themselves.
