The way a person’s eyes move can show whether or not the person recognizes someone else -- even if they try to hide it. That is what a team of international researchers reported recently. The finding could be important for criminal investigators, who often seek information from uncooperative witnesses or suspects. Law enforcement officers often turn to lie-detector tests during criminal investigations. But the test results are not always correct. When asked questions critical to a criminal case, a fast heartbeat or sweaty, sticky hands might make a nervous truth-teller appear to be lying. And, an experienced liar might be able to control those signs and avoid suspicion. Our eyes look at a familiar face differently than they do an unfamiliar one. When people look at unfamiliar faces, their eyes usually move from one feature -- like the shape of the nose -- to other features. Their eyes stop quickly and often as they try to identify the unknown person. When looking at a familiar face, people usually direct their attention to just a few facial features.
