People who look at you look away and not telling the truth, says the popular belief. In this regard, current theory holds that there is a relationship between eye movements and tell the truth, which is a key element in Neuro Linguistic Programming (NLP) and dynamic formal model of how the mind and human perception . If you try to lie or be honest, it is believed that right-handed people, who look up to the right, display a constructed or imagined event. While people who do the left, might be viewing a memory of the memory.
True or false?
To check how true is this belief, British researchers at the University of Edinburgh and the University of Hertfordshire, conducted a study that argues that this claim is unfounded. In the first part, the research published in the journal PLoS ONE, filmed a group of volunteers who are filming their eye movements, either telling a story true or false. After this, their eye movements were coded.
In a second step, the scientists worked with another group of volunteers informed about the theories of Neuro Linguistic Programming, to whom was asked to review the tapes and try to detect who lied observing eye movement of the participants. But know not demonstrated that improved the detection of lies. In this regard, Richard Wiseman, a psychologist at the University of Hertfordshire, said that “the results of the first study showed no relationship between lying and eye movement and the second showed that inform people about the claims made by NLP practitioners did not improve their ability to detect lies.”
Abandon the belief
The survey involved a third phase in which we analyzed videos of people who sought help from family have disappeared or have been victims of a crime. For researchers, this suggests that differences in the behavior of liars and those who say the truth, but there are no patterns in eye movements. Following this research, the position of these scientists is sharp, because they found no grounds to substantiate certain eye movements are a sign of lying, so they suggested abandoning that belief. “It’s time to leave that way to detect deception,” said Caroline Watt, researcher at the University of Edinburgh.
