Microexpressions

Micro

Microexpressions, such as this furrowed forehead (a negative thought indicator) are called “leaked” because they happen quickly and last only fractions of a second before disappearing. Because they are difficult to control, they tend to be reliable indicators of truly felt emotions.

 

Microexpressions are facial movements or expressions that flash across the face at such a fast rate that they are barely perceivable. Slow motion replays of high speed videography easily shows what is difficult to see in real time. The persistence of these cues range from 1/25 to 1/5 of a second. It is the study of microexpressions that assumes that certain aspects of facial expressions reveal this duplicity to betray the liar. The research was originally pioneer by Guillaume Duchenne in the 1800s as we saw in an earlier chapter who discerned the difference between real and fake smiles from the use of the zygomatic major muscles which pull the corners of the mouth upward and the orbicularis oculi, the muscle around the eye that pulls the cheek up while lowering the brow. This was the true smile and in the same way, other unconscious microgestures reveal negative emotions. Presumably it is more difficult to prevent a felt emotion in addition to creating a false emotion than to simply neutralize the face. The term “masked” refers to any facial emotion that is either replaced by a different falsified expression, or is neutralized with no emotion present. This is when microexpressions should be most evident.

Microexpressions, on the other hand, are tied to leakage in so much as they are an attempt to hide our true feelings. When we tell a lie, and if we hold any remorse for that lie, repressed or otherwise, our faces should reveal these cues through facial expressions. When a deceiver tries to repress an emotion caused by lying, the result is a micro display that briefly comes across the face instead. Other times these cues happen at a much slower rate and are perceivable by the naked eye. Those that can intuitively detect lies often score high on the ability to recognize microexpressions.

Lies can be betrayed by signs of emotions as they relate to microexpressions or in other words, it is difficult for a liar to create emotions that don’t exist. For example, it is difficult to consciously narrow the red margins of the lips so this can be an indicator of feigned anger. Rarely do we detect these fake emotions though, which is partly due to the fact that we simply don’t care to know the truth as it serves no useful purpose to us; there is no reward or incentive.

A study conducted in 2008 by Stephen Porter and Leanne Brinke of Dalhouse University who examined microexpressions through the examination of high speed video cameras found some, but incomplete support, for their use in detecting feigned emotions. In fact the emotions they did uncover occurred over a much longer time which could suggest that they might be easier to detect than previously though. They also found that it was far easier to neutralize the face (show no expression) than to create an artificial emotion. In the neutral face, they found a lower blink rate, possibly due to the effects of claming up, but where a masked face appeared, they found increased blinking likely due to the stress associated with faking a face. Other studies suggest that liars increase blink rate, as we recall. They also found that all participants showed at least one inconsistent emotion during deception showing that leakage might be ubiquitous, but the overall success rate was still only sixty percent. Confusing the findings further, they found that microexpressions were found throughout positive emotions.

To date very little study has gone into microexpressions which is surprising given the widespread attention is had been given. It is currently being utilized as a massive foundation for the U.S. transportation agency to help identify suspicious passengers. While the science is incomplete with regards to microexpressions, it is important to realize their existence, real or not, because the next time we wait to board a plane, the eye in the sky and the personnel on the floor are eagerly watching for our nervous ticks for the opportunity to pull us aside for more questioning. The rational of course is that while nervous ticks might not accurately betray a liar all the time, it does form a basis to increase the level of investigation even if there are occasional misses. The (not too?) distant future might hold recognition software that reads all levels of being, from gait to blood pressure, voice inconsistencies and perhaps microexpressions. Most experts agree that this technology, due to its complex nature, won’t be in production for some time though.

Summary – Chapter 6

We saw, in this chapter on smiles and laughter, that smiles are controlled by two sets of muscles called the zygomatic major muscles, that run down the side of the face to connect the corners of the mouth and the orbicularis oculi to help pull the eyes back. The orbicularis oculi produces crow’s feet, smiling eyes or Duchenne smiles, all names meaning the same thing; “real smiles.” The zygomatic muscles, on the other hand, are consciously controlled and can be a giveaway to a false smile as does asymmetry.

Next we looked at the origins of the smile, be it from fear as in the “fear grin”, or from happiness and whether happiness creates smiling or vice versa. We concluded that smiles today symbolize submission and are contagious. We then found that there are five commons smiles, the tight lipped smile with low intensity (indicating a hidden attitude or thought), tight lipped smile with high intensity (not a full honest smile but shows openness), the uneven smile (tongue-in-cheek humour or sarcasm), the upper smile (hidden agenda), the grin or smirk (indicating smugness and arrogance) and the broad smile (a true smile). We found that smiles generate leniency, release endorphins so can be addictive, and that women are more likely to smile than men and do so to placate them. We then covered context as it relates to humour and how humour has many different forms, how humour helps people bond and that it isn’t unique to humans since rats and gorillas emit similar vocalizations. We then looked at the differences between the sexes and saw that women laugh much more at men, than do men at women, suggesting a courtship link to laughter and that men use humour to playfully insult other men whereas women use it to bond. We then discovered that put-down humour can create belongingness so long as it is well received and avoids hitting on insulting truisms, that women should avoid snorting since it is unsexy and that laughter can help people recover from illness.

The Most Common Types Of Smiles

The following is a comprehensive list, with accompanying description, outlining the various smiles you might encounter.

______________________________________________________________________________________________

The tight lipped smile with low intensity.

The tight lipped smile with low intensity.

ONE. The tight lipped smile with low intensity. This smile happens as the lips are stretched across the face and no teeth are showing. The tight lipped smile can vary with intensity as well, and it is directly related to the amount the lips are raise in the corners of the mouth. The low intensity smile has very little upward curl in the corner of the mouth and indicates a hidden attitude or thought, uncertainty, hesitation or lack of confidence. In this smile the lips are stretched toward the ears with no curl using muscles called the risorius. The risorius muscles are unable to raise the corner of the lips. Small babies have been shown to use this smile for all others except their mothers whom they reserve the use of the true smile. This smile is used to placate others or to pose for photographs when we aren’t in the mood. Strangers passing on the street might also use this shallow smile as a form of greeting or acknowledgement. The smile is a feigned or dishonest smile so that others don’t catch on that we actually don’t like them. It might also appear out of nervousness or stressed, so it can appear when meeting new people. For this reason we can call the tight lipped smile the “polite smile.” When the tight lipped smile with low intensity happens in conversation in can serve to negate the previous statement. For example, a man might say about his boss “He’s a great boss, I’d switch companies and follow him anywhere if he left.” and this might be followed by a tight lipped smile serving to negate the comment.

TWO. Tight lipped smile with high intensity. This is a variation on the smile above, yet the corners of the lips rise even further with some teeth showing. The lips are slightly separated, the corners of the mouth are upturned, gaze is steady and warm and the posture is relaxed. We find this smile appearing when meeting new acquaintances, so it’s not a full honest smile, but does show openness to others. The tight lipped smile with high intensity is more appropriate for acquaintances because a full smile is reserved for our friends and family and would only come off as insincere with new company. A full smile around new people would lead them to think “What’s that guy’s problem, he’s grinning like we were the best of friends, yet we just met.”

The uneven smile.  This one is a fake!

THREE. The uneven smile. We might see this smile associated with tongue-in-cheek humour or sarcasm. The smile happens when only one side of the face sports a smile and the other side does not. The opposite side may even be down turned or frowning. The uneven smile depicts a frame of mind in which opposite emotions are present. The uneven smile would accompany cheeky humour amongst friends and would crack to show others that sarcasm was intended. We rarely see this expression aside from in the West, since sarcasm is much less common around the world.

______________________________________________________________________________________________

FOUR. The upper smile. In this smile, the upper lid is raised to expose only the top row of teeth, but the true significance is that the lower teeth remain hidden. In the upper smile the jaw and teeth remain closed and the message conveyed is of medium pleasure and comes off as insecure. Used car salesman, who beam light from their teeth in this way, will seem to have a hidden agenda.

______________________________________________________________________________________________

The grin or smirk.

The grin or smirk.

FIVE. The grin or smirk. The smirk indicates smugness and arrogance. It is a tight lipped smile with the addition of a degree self satisfaction for good measure. A nervous smile often appears like a smirk but they are not to be confused. The smirk has accompanying dominant body language such as head back, shoulders back, open postures along with dialogue riddle with exuberant pride. The smirk will happen too when someone is under direct verbal attack. It’s the sort of face that makes you want to say “Wipe that grin off your face”. Sometimes though the smirk is due to the stress of being put under fire and isn’t always an attempt at questioning authority.

______________________________________________________________________________________________

The broad smile.

The broad smile.

SIX. Broad smile. In this smile the upper and lower teeth are made visible. The gaze is relaxed and the smile is intended to convey joy and pleasure. This is a true smile and not one that is easily faked. The tell tale sign of an honest smile, is the appearance of crow’s feet in the corners of the eyes. Crow feet make it seem as though the eyes are smiling. It is difficult to replicate these smiles without being truly amused or in good company as the muscles are usually out of our conscious control. We should be careful to use this smile, as with all smiles, when most appropriate, as in the wrong context will simply appear insincere.

______________________________________________________________________________________________

The downturned smile.

The down-turned smile.

SEVEN. Down-turned smile or reverse smile.  Happens when the mouth is inverted into a down-facing “u” shape.  It indicates high stress, unhappiness, anger, tension and depression.

Baselining Versus Innate Actions

A 'true smile,' where the corners of they eyes crease, is difficult to fake

There are some key body language gestures which are mentioned throughout the book that don’t need to be compare to a baseline as they tend to be innate and not learned. These gestures will give us clues as to whether actions are currently on their natural baseline or are as a result of some other underlying stress. Some things to consider when formulating a baseline includes a catalog of how often a person gestures and which direction their eyes stare when they are thinking and analyzing (can be an indicator of creative thought or recalling as we shall cover in a later chapter), how do they act when they are successful and what do they do when they are stressed? It is difficult and probably unnecessary for me to offer help in establishing baseline techniques since it’s a natural process that we all do daily. However, the take home message has more to do with protecting ourselves from thinking that all gestures in body language are universal and ubiquitous across all people. This book will help determine cues that fall in and around the baselines of the people around you and provided educated guesses as to their meaning, but this is not to say that each cue means the same thing for everyone.

A final word on proper establishment of baselines is to place most emphasis of a person when they are relaxed or when they are in a normal mood and state. Don’t baseline someone when they are getting ready to go on stage to speak in public or if they are going through a divorce, or have had a recent death in the family. Their body language will be misleading and uncharacteristic. Definitely take culture and intuition into your baseline, but avoid things like projecting and making assumptions. Assumptions clog our ability to see what is really happening because we are putting our thoughts and feelings which we have inside ourselves on someone else. Our life history and experiences do play some purpose when we read people, but they can’t be the dominant force, so don’t let your biases control how you read people. Keep in mind too that almost every other person will look at body language naively. They will think that “A” means “B”, when in fact it might mean “C”, “D” or nothing at all. As an aside, you might want to be careful about using body language to influence others, since your signals might be misread or simply go unnoticed altogether.

So the message here is, just because so and so does this or that, it doesn’t mean one hundred percent this or that! Compare apples to apples and oranges to oranges and him or her to his or her baseline! This will produce a much more accurate read.
