The Feet Are Honest

Feet aimed toward another person says "I'm interested in YOU."

Feet aimed toward another person says “I’m interested in YOU.”

It has been said that the feet are the most honest part of the body as it applies to the language they emit. Millions of years ago, we gave up quadrupedalism to walk upright leaving our feet to the dirt. While our hands busied themselves with other complex tasks like fire building, making clothing and shelters, throwing spears our legs were relegated to more primitive activities like locomotion. The hands, because of their opposable thumbs are more useful to complex tasks putting the thinking neocortex in charge. This in turn hampers honest language because the thinking mind can, within reason, eliminate the type of body language it desires.

These feet want to escape and so are turned away.

These feet want to escape and so are turned toward the escape route.

The feet on the other hand, carried out more traditional tasks like escaping predators, avoiding hot sand or coals from the fire, leaping from slithering snakes or poisonous spiders, or navigating rough rocking river bottoms. The feet were therefore connected more to the reptilian brain which reacts to stimuli directly instead of contemplating higher order tasks that require planning. When we’re frightened it doesn’t take much to put our feet in gear by getting them tucked under our legs and coiled up, or freezing instantly or get pulled up onto a chair when startled by a mouse that catches our eye scampering across the shadows of a room. Our feet carry the flight or fight reaction to the letter, although they tend to first freeze, then take flight through distancing them from negative stimuli, and if neither is possible will begin to kick or fight. None of these tasks require high order thinking, they are based on reaction and are immediate.

The same sorts of positive reactions can be read in the feet. For example, we know that children are interested in play rather then eating when their legs bounce at the dinner table quickly trying to eat their food so they don’t miss the next inning in street ball. Even if they don’t fidget the feet will still point, or inch toward to door in effort to prepare for escape. Even the feet of adults reveal true emotions by pointing away from boring conversations or toward a lover. Adults can also be seen “Jumping for joy”, even if rarely such as when they are surprised by winnings at the casino slots, or are when met with a grandson at the airport. People of all ages can seem to float on their feet showing joy, which is an important “gravity defying” body language showing that they are excited. Young babies and toddlers, when held by a parent who’s been absent for a short while, will kick up and down and the entire body will jump with joy despite being confined in an embrace. None of a child’s body is as exuberant as their legs and feet!

It is not all that surprising that our feet go unnoticed. Our faces are complicated and at times expressive, even though we quickly learn to hide our emotions so as to deceive others. We learn early enough that when cameras are shoved in our faces, to smile, even though we have nothing to smile about or to “turn that frown upside down” when we are in a bad mood. Naturally we get good at feigning emotions with our “poker faces.” Yet throughout the years, our feet pass under the radar, tucked under tables, hidden under clothing and shoes to do menial tasks like bring us from point A to point B and back again. Our feet and legs can display boredom through repetitive motions, joy by lifting the body up and down, fear by being tucked under a chair, depression by laying lazily or motionless and sensuality by being uncovered and flaunted. The list goes on.

As you read this book pay particular attention to foot and leg language which is peppered throughout, as these will be cues that indicate true hidden meaning and emotions that is much more reliable than other body language cues.

How The Lymbic System Affects Body Language

The limbic system is a set of brain centers including the amygdale, hippocampus, anterior thalamic nuclei, and limbic cortex. These structures in collection handle emotion, behavior, long term memory and olfaction or the sense of smell. In 1952 researcher Paul MacLean started using terms to divide the brain by function and what he thought was their origin. He called collections of the brain the “reptilian brain” which included the base of the brain and brain stem, the “mammalian brain” or the limbic brain and the “neocortex” or human brain. Scientists have proposed that the brain has evolved from a primitive reptilian brain to the more complex neocortex. By examining images of the brain, it become apparent to scientists that the brain has “stacked” specialized structure upon specialized structure in what seems like a progress through time. Think of how rocks form through sedimentation over time, and you have a rough idea of how brains have evolved. By moving inwards from the outer layers of the brain to the center it has been theorizes that one is moving back in time to the original “primitive” brain. This is why the center brain is called the reptilian (original, less complex) brain whereas the neocortex (“neo” meaning new, more complex) which the mammalian brain, is located on the outside.

As it applies to nonverbal behaviour, it is the limbic brain that is responsible because it reacts naturally to the world around us, and the stimulus it contains. Behaviours produced by the limbic brain, over say behaviours that are controlled by the neocortex, are a true honest response. In other words, the limbic brain controls emotional body language so it’s our best gauge to indicate what the body is really feeling. It is the limbic brain that controls the arms, feet, hands, heads, and torsos when someone is feeling embarrassed or ashamed, sad, fearful, excited or happy. The limbic brain is hardwired into our nervous system and goes back in time with us through our evolution.

While our neocortex can at times suppress the limbic brain, it can only do so when it is no occupied doing other things. The neocortex is in charge of doing complex conscious tasks (like calculus, engineering, and so forth), so when it is overwhelmed or turned off entirely, the body accidentally leaks emotional body language for others to read. The neocortex, because it is under conscious control, is the least reliable and least honest part of the brain. Research shows that the neocortex is the most active part of the brain during deception which is why it has been called the “lying brain.” Cheats might be able to control the words they use to describe their thoughts, but they can’t control their visceral reactions to these words, nor can they control their expressions stemming from this motivation. This is exactly how and why we can catch liars, read fear, stress, sadness, anger and so on.

Turtling is a limbic response to confrontation. The head sinks, shoulders shrug, and the body takes on a smaller form to avoid being seen as a threat.

When you think of the limbic brain imagine the autonomic response that happens when we are startled by a loud bang. Naturally our bodies tense up, our heads duck into our torsos and our hands are pulled inward while our nervous system puts our heart into high gear through a dose of adrenaline. It is the same part of the brain that makes the feet fidget or hands shake when excited, or makes our hands sweat when under pressure. Our limbic brain also goes into hyper-drive when we see a distant relative after years apart, or when someone wins the lottery or gets a strong hand in poker. No matter what we do, we can’t stop this from happening. I will add too, that with some practice we can learn to hide, or minimize even these reptilian behaviours such as clasping the hands together to reduce shaking when excited, or tucking the legs in behind a chair to lock them in place when someone really wants to flee. However, even this body language shows the neocortex trying to override the reptilian brain and in so doing producing yet another stream of body language for us to read. At the scene of an accident we fully expect to see the limbic system take over producing trembling, nervousness, and discomfort. What would First Responders be left thinking if they showed up at an “accident” where the caller was relaxed and calm, yet the victim lay strewn about, dying and bloodied? Naturally, the police would think something was amiss and would pull the witness aside as a prime suspect for a crime. Therefore, we should always look for limbic responses and tie them to context so we know when something is not right. When limbic responses stop, we know that the stimulus for their creation has also stopped, so we must then find out the reason.

The limbic brain is the part of the brain that controls our root processes. To put this into perspective, imagine the activities in the repertoire of a lizard. Being cold blooded, he seeks sun when possible to speed up his metabolism, eats when hungry, drinks when thirsty, either freezes, flees, or fights when scared, and has sex when horny. He does not do calculus or engineer tall skyscrapers because he does not have the capacity, but this notwithstanding; he survives, because his limbic mind tells him everything necessary to do so. In evolutionary terms, so too does our limbic mind. It tells us when to be scared and what to do about it, be it freeze and reduce movement so as to get under the radar of assailants, to run and so get our feet pointed in the right direction, to get our hearts pumping to run and so on. It also controls root emotions – it tells our feet to move and jump with joy, and fidget in preparation to leave when bored.
