Eye movements may reveal
whether a person is lying, says study
As per a study, eye movements
can reveal whether a person is lying about recognising someone they know.
The finding could be valuable to police when trying to confirm key
identities in criminal networks such as terrorist cells or gangs, researchers
said.
Using eye tracking technology, researchers from the University of
Portsmouth in the UK found that people's eyes move in a different pattern when
looking at faces they recognise.
"Criminal accomplices often deny that they know other members in
their networks.
However, if a co-conspirator denies recognition in this way, their eye
movements when viewing photos of those suspects, may reveal this type of
lie," said Ailsa Millen, lead author of the study.
The researchers recorded the eye movements of 59 participants while
looking at 200 digital colour photographs of familiar and unfamiliar faces.
Familiar faces included people the participants knew in real life,
famous celebrities and those only seen briefly before the experimental trials.
Sometimes the participants lied about whether they recognised the
photos, sometimes they told the truth.
