Tiny physical ticks might be subtle warning signs that you're in the company of a psychopath.

The personality characteristics that point to psychopathy include antisocial behavior, remorselessness, deception and interpersonal manipulation.

But studies suggest that people who do not yawn when they see someone else do it score higher on psychopathic traits.

The theory is that contagious yawning is driven by empathy - something psychopaths lack. Meanwhile, research suggests there are four other tell-tale physical signs that you're dealing with a psychopath.

Less likely to yawn contagiously

A study conducted by Baylor University in Texas in 2015 analyzed 135 students tested for traits such as Machiavellian egocentricity (a tendency only to consider personal needs), cold-heartedness and rebellious nonconformity.

As is widely known, most people will yawn if someone around them yawns and shows signs of fatigue. The students were shown video clips of people using different facial expressions, including yawning.

The ones who scored highly for cold-heartedness were less likely to yawn.

Brian Rundle, a PhD student involved with the study, told The Times: 'One of the biggest lines of evidence is that (contagious yawning is) very much related to empathy.

'While this is a really interesting finding, it doesn't mean that if you're not affected by a contagious yawn, there's something wrong with you.

'There's some evidence to show that in baboons, dogs, or chimps, the alpha male tends to yawn first,' he added.

'If you're sitting around the campfire, it cues everyone else to yawn, and instead of going to bed at separate times, they all do it simultaneously.'

Other signs include beat hand gestures that psychopaths like Charles Manson might use to emphasize what they want you to hear and downplay what they do not

Limited head movements 

This physical trait was uncovered by a team at the University of New Mexico in Albuquerque.

Scientists developed a specific algorithm that analyzes head movements and tested it on 507 inmates during recorded conversations, varying in length from one to two hours.

Inmates with 'severe and life-course-persistent antisocial behavior' had more rigid and focused orienting of their head during the session, they found. 

The results are interesting because excessive non-verbal cues like head movements, blinks and hand gestures have been linked to deception.

As far back as 900 BC, it was observed that deceitful people demonstrated excessive fidgeting,
