The blink flurry, aka the eyelid flutter, a rapid succession of three or more blinks, has been connected to a high cognitive or emotional load and deception. This article summarises the scientific and anecdotal evidence, shedding light on this intriguing yet common behaviour.

I recently contributed to Body + Soul’s article on how to stop being a conversation killer. In the article, I talk about body language and expression that can kill a conversation. While, Psychologist, Lauren Florko talks about common mistakes conversation killers make.

Listen to my discussion with Philip Clark (and guests) from ABC Radio, on Nightlife’s Body Language episode. In this article, you can also find out what I do to conquer pre-interview nerves and the fear of public speaking.

Gladys Berejiklian’s strange cheek sucking and cheek puffing nonverbal behaviours at recent press conferences have caught the attention of the media. Read this article to find out the meaning of cheek sucking and cheek puffing behaviours. And why Gladys Berejiklian attempts to suppress her emotion.

A body language expert explains the deeper things you can tell from a person’s body language and posture. If you know what you're looking for.

It turns out Ronan Keating had it right when he sang “you say it best when you say nothing at all,” because non-verbal behaviours such as body posture and body language can provide great insight into a person from their personality, to their mood and emotions.

When I was asked by ABC Radio Perth to look at Bernard Tomic’s nonverbal behaviour, I surprised to see a series of flirtatious winks, backed up by his verbal message. It was on closer inspection I discovered some other interesting and telling behaviours, which revealed the bigger picture. In this post, I shed light on Tomic’s true emotion.

A recent request to analyse Gable Tostee’s behaviour and statements from a 60 Minutes interview with Liam Bartlett, led me through an emotional journey of surprise, contempt, sadness, disgust and anger–almost all of the universal expressions of emotion. How could this case have ended up with an acquittal?

In this post, we seek to discover the truth, reading the body language of the Skripal poisoning suspects–Russian spies, Alexander Petrov and Ruslan Boshirov. Are they lying about their true identity?

Why do we judge people from the moment we see them? And when we feel threatened by them, what happens during our body’s emergency response to fear. Read about my involuntary nonverbal behaviours when I encountered a guy with Tourette Syndrome. Both our bodies reacting to a stimulus.

Last week a client asked me if I'd ever blogged about Lloyd Rayney, a prominent Perth Barrister, who in 2010 was charged with the murder of his wife (2007). He was found 'not guilty' in 2012. I'm not too familiar with the case as I didn't pay much attention to it at the time; back then I lived in the UK and later, on the other side of Australia, in Sydney. From what little I had heard, since moving to Perth a year ago, I assumed Lloyd Rayney was guilty. This was largely based on public consensus in Perth, though I don't directly recall any conversations about the case, so most likely I've been swayed by the media.

You probably felt awkward when you saw South Korea expert, Professor Kelly's reaction as he was interrupted by his children during his BBC interview. But do you know why you felt his discomfort? Find out which nonverbal behaviour repeated nine times, to make you feel his pain.

Part two, The Role of your Body in Eliciting Truth, of my article Deception Detection Uncovered; Truth Seeking Through Interrogation, is out now in Australian Security Magazine.

Part one, Identifying Nonverbal Cues, Clues to Dig Deeper, looked at several nonverbal cues that, when seen, alert us to a potential issue; an area in which we should dig deeper in our quest to discover the truth or true feelings. Part two, The Role of your Body in Eliciting Truth, explores the other side of the equation; how you can use your own body language, gesture and expression to facilitate truth seeking. 

This weekend Trump apologised for his comments from the recently uncovered 2005 video, in which he brags to Billy Bush about his advances on, and treatment of, women:

"You know I'm automatically attracted to beautiful [women] I just start kissing them. It's like a magnet. Just kiss. I don't even wait. And when you're a star they let you do it. You can do anything. Grab them by the pussy. You can do anything."

During his apology, we see a one-sided shoulder shrug. This is a nonverbal cue, usually associated with lying, due to it's meaning. It signals that the speaker has no confidence in the words they speak. A full shoulder shrug (both shoulders) signals the opposite; confidence in spoken words.

These two nonverbal cues can be seen in video footage of Adeel Khan, who today, was found guilty of deliberately setting the convenience store alight and murdering the man who lived upstairs. Khan pleaded not guilty to all charges. In this video, (at approx. 45 seconds) Khan's blink rate increases to 100 blinks per minute, in response to the question, "Mr Khan, I'll ask you, did you burn down the property?". There's a clear distinction between blink rate before and after the question. 

When we experience positive emotions, various parts of the body point upwards, defying gravity. This video snippet, a Malcolm Turnbull interview, is a good example of gravity-defying body language. Turnbull defies gravity several times, elevating his body as he raises on his toes, each time he talks about positive outcomes.
