Cadence Intonation (linguistics), the variation of pitch and tempo in speech tempo. The pace often slows when people are concentrating.

Canalizing To give a particular direction to or provide an outlet for something.

Casual crowds A group or gathering whose members are unaware that they are part of a crowd and yet they obey the rules, often complex ones such as pedestrians walking in various directions but avoiding contact, through following unwritten, unconscious rules.

CAT communication accommodation theory People adopt aspects of speech patterns in efforts to strengthen bonds or acceptance, or influence a relationship. This includes reducing differences of dialect, accent and word usage when wishing to emphasis contrast, and increasing the similarities/regularities when seeking approval.

Catapult A body position in which the hands are clasped behind head, elbows back, chest puffed out, legs stretched out. The result is an increased body size suggesting confidence, self-satisfaction, or high status, but as this makes the individual look threatening it can be considered disguised aggression.

Categories Humans learn concept by separating the similar and grouping them. We infer or summarise once a person has been placed in a category. It’s categories that allow people to compare and contrast.

Cathartic A cathartic behaviour providing psychological relief through the open expression of strong emotions; causing catharsis, such as exhalation which can express relief.

Center-stage effect People situated in the middle of a group tend to be overlooked, or paid less attention to, than other members. Typically, this applies to lectures, with public speakers making more eye contact with those to their left and right sides.

Certainty A firm conviction or lack of doubt, which can be signalled by a single nod, erect posture, power posing, solid gestures and handshaking, plus a swiftness of dismissive behaviours if/when their conviction is challenged.

Chair straddle As with the power pose stance, the feet placed beyond the width of the hips, but this time the doer straddle a chair, with the back of the seat in front of them. Despite the obvious use of a barrier this is considered a dominant, masculine pose, and phallic display (despite the chair covering this area). 

Chameleon effect A term first used by Chartrand & Bargh, chameleons are mimics, assuming the attitudes, appearance and actions of others they wish to emulate or impress, possibly to influence. The opposite to ‘leopards’ who make effort to fit in, says King, chameleons are adept at reading people and are continually adjusting to fit in.

Channels of communication These are many different ways in which people communicate messages. Some categorise them as facial expressions, body language, voice, verbal content, verbal style and back-channelling; others as haptics, vocalics, kinesics, proxemics, etc. 


Checking belongings When people are in stressful situations they often check their belongings. Perhaps patting a pocket to check a wallet's presence, moving their phone closer, pulling a bag close, or checking tickets prior to a performance or journey. These reassure and keep the brain busy, releasing mental energy. 


Cheek biting A pacifier performed when experiencing stress. A self-restraint or self-punishment action as an individual attempt to gain control.

Cheek framing When the jaw is rested on a thumb with the hand’s index finger vertical alongside the cheek. Often performed when a doer, in thought, is weighing up their options or considering how to process the information they are hearing. 

Cheek screw A rotating straight forefinger is pressed into the centre of a cheek, commonly used by men in Italy to signal that a woman is attractive.

Cheek touch Often a pacifier, when someone touches their cheek it can be to relieve stress. It may also signal boredom. 

Cheeks Can be revealing, both in their appearance and movements. From blushing to smiling, to make up and beards - or the width of one’s face - cheeks communicate. 

Chemosignals Human communicate their emotional states to each other through chemical signals. For example, the smell of fish enhances suspicion. Fear signals confer a survival advantage through sensory acquisition, whilst a disgust signals trigger sensory rejection, another survival enhancer.

Chest puffing Like many other animals, humans puff out their chests when aiming for territorial dominance. This can be a display of aggression when space has been violated. Chest puffing, if combined with the pulling in of the stomach can also be an attempt to make oneself more sexually attractive.

Chewing Oral comforting actions can come in the form of object adapters including the likes of chewing a pencil or gum, or nail biting. They are often performed when the brain requires the release of calming endorphins such as those stimulated through chewing. This action also helps the face move, which is shown to be preferable to receivers than seeing a stone face.

Chin Chin behaviour communicates and protects. Even a static, neutral chin sends a signal. Chin size for example, as it can be an indicator of testosterone levels. If a palm covers the chin, preventing its movement, it can be that an attempt to hide an emotion is taking place, or that the person is bored.

Chin down If fleeting and combined with wide open eyes, surprise can be assumed. A dropped chin can also be part of a smile but it’s usually done when hearing bad or sad news. If done with lowered shoulders it may signal refusal.  

Chin flick This involves placing the fingertips of one hand under your chin, pointing to the neck, before scraping and flicking the fingers outwards, towards the target of the message, which says, no, I can’t or I don’t wish to, communicated in an insulting manner. More commonly performed in France and Italy.

Chin jut This appears to be a universal sign of aggression or aggrievance, usually combined with superiority and arrogance. This gesture exposes the throat, demonstrating prepared risk or fearlessness, often directed at a competitor in a challenging way. It can also be performed as an adaptor, especially by men wearing shirts (ventilating). Del Boy (from Only Fools and Horses) does this habitually. The chin jut action has a cultural significance too, as it's used to point directions or signal agreement in certain Eastern countries. 

Chin lift Raising the chin often signals a feeling of confidence or superiority.

Chin point By stretching the neck and pointing the chin, direction can be signalled. This is favoured to pointing with a finger or hand in some countries.

Chin quiver/wrinkle The puckered or wrinkled chin may be a defensive action such as pulling away from a threat. Often combined with a withdrawn chin, if the lips pout it can be a show of defiance.

Chin stroke Associated with thinking and curiosity, this auto-contact movement is a common pacifier.

Chin tuck Protects the vulnerable neck area - protect the trachea and carotid artery - especially if combined with the shoulders raising (or head lowering). The chin tuck lowers the head in a submissive gesture if the eyes gaze downward. A tucked chin is form of withdrawal/distancing but if the head is tiled back it can signal superiority and contempt.

Chin withdraw Similar to the chin tuck, it can be a sign of distancing and protection. The chin pulling back may show doubt or anxiety.

Choreographed gestures If planning a speech or rehearing a performance it’s useful to choreograph gestures. Composing the order and timing of movements helps one’s own memory and facilitates greater audience comprehension.


Clasped hands Can be a sign of self restraint or psychological turbulence, tension being displaced to the grip, the more intense the grip, or interlocked the fingers, the more stress is being experienced. If the clasped hands are raised it may mean frustration. When attempting to deceive it’s also true that fewer gestures and more hand clasping is undertaken. However, the handclasp doesn’t usually relate to stress or anxiety if the clasp is light of grip. If the back of one hand is placed in the palm of the other, either in front of the stomach or behind the back, it may simply be a position of comfort. Locking fingers is common on done for many reasons. Check for the looseness of (or tension in) the fingers as well as accompanying behaviours. 

CLEM conjugate lateral eye movements Coordinated movements of the eye laterally from side, controlled by the paramedian pontine reticular formation. These involuntary eye movements can signal a mind in the process of making a decision or reflecting. Harnad noted that rightward movement is associated with symbolic thinking, while leftward movement associated with visual thinking.

Clenching Humans clench many different muscles at times of stress. A clenched fist can signal frustration or anger, clenched hands restraint or a negative attitude, and clenched buttocks anxiety or fear. Tight lips with a clenched jaw are universal signs that something is wrong.

Closed body language When the body becomes smaller and withdrawn, usually with crossed limbs, a closed posture is adopted. Props can also be used to close off engagement. A sudden movement to a closed position can signal a negative change in mood. However, when someone is cold, their body language looks much like a closed, defensive position. When feet are brought together in a seated position, look for tension in the legs. This is an emotionally closed posture, unlike the same position but with more relaxed muscles. 

Clusters When decoding body language it is always worth looking for clusters, combinations of three or more indicators suggesting the same message.

Cocooning A recoiling action such as curling up or self-hugging, aimed to shut off outside disturbance. More subtle versions like looking at a phone whilst listening to headphones can also be a cocooning behaviour.

Co-evolution The process by which the simultaneous development of two or more organisms occurs. It could be two animals that have coevolved due to a mutual dependency, influence or interaction such as predator and prey, or the beneficial partnership between human and dog.

Cognitive ease Concerned with how our brains process a piece of information, cognitive ease is the measure of how easy this is. The Cognitive ease associated with something will alter how we feel about it and whether we are motivated to invest our time and effort in it. Cognitive ease can help people who have an easy to pronounce name or familiar face. It feels good, but also gives us a false sense of security because it makes us think we understand far more than we actually do.

Cognitive dissonance The mental discomfort (psychological stress) experienced by a person who holds two or more contradictory beliefs, ideas, or values. This state of having inconsistent thoughts, beliefs, or attitudes especially applies to behavioural decisions and attitude change.

Cognitive style Describes the way individuals think, perceive and remember information. Learning is more efficient is a teacher has a similar cognitive style to their pupil.

Cold reading Without the prior knowledge of baselining, or sometimes even context, high-probability guesses are made from signals picked up instantly. Using various cues such as posture, attire, gender, ethnicity, age, hairstyle, information is quickly gathered and tested to form impressions.

Collar pull Ventilation performed when ‘hot under the collar’. A similar action to sweeping hair away, the collar pull usually involved two fingers running along the inside of the collar when stress requires the need for air. The tingling sensation in the neck tissues, perhaps caused by lying, or increased blood pressure and subsequent sweat, can lead to this behaviour.

Collective intentionality Characterises the intentionality that occurs when two or more individuals undertake a task together. To communicate emotion both sender and receiver need a shared understanding of it. It may be that the accepted look of emotion – its corresponding facial expression – is no more than an agreed set of muscular and cardiovascular changes in the given context, necessary to communicate emotion.


Comfort blanket An object that brings psychological comfort or eases anxiety. Also known as a security blanket is refers to the common item that infants cling to at bedtime or carry around with them, typically covering their ventral region. Not restricted to blankets, these object can be other props.

Comfort dividend The benefit gained by putting people at ease, perhaps by making their environment comfortable.

Compassion Sympathetic pity and concern for the sufferings or misfortunes of others, compassion is a basic human nature. When observing suffering most humans feel compassion, something we feel more readily when watching than other emotions.

Complexion The combination of the hot, cold, moist, and dry qualities held in medieval physiology to determine the quality of a body, people now see complexion as the general hue or appearance of the skin and especially of the face.

Compound gestures Involve many independent key elements. Examples are shrugging (palms up, shoulders hunched etc) and laughing (head-back, closed eyes etc).

Compressed lips Perhaps originating from a response to foul tasting food, tight lips with a closed mouth is a common reaction to seeing or hearing something we deem negative. Compressed lips also signal concealment.


Congruence Physical actions should be consistent and one’s physical attitude should match a mental one. There should be congruence between body expressions (posture, gait etc) and facial expressions, tone of voice and other nonverbal channels of communication, if a message is to be encoded successfully. If these are not aligned the message may not be effective. Incongruence with lead to the most negative messages of a mixed signal being that which is decoded.

Conscious gesture This is a deliberate action, made with the sender’s awareness, and typically made to send a message.

Comfort display Behaviour which suggests that the doer is feeling comfortable or relaxed, such as open, splayed body language.

Concealed irritation The act of attempting to hide an emotional reaction or feeling by consciously masking or adopting a different expression. In some cases this concealment can be unconscious, such as the contempt expression, which attempts to hide and suppress.

Confidence Confident people take up more space both vertically, in the form of erect postures, horizontally, in terms of spreading out, and their gait, with striding out or bouncing steps and swinging arms. This space filling also includes legs being stretched out when sitting. Gravity defying behaviours of the face (chin up, nose raised) can signal confidence, whilst confident people use fewer (but bolder) gestures, and usually keep their palms and thumbs visible. The antithesis is apprehension. Raised/visible thumbs, even when arms are crossed, can show confidence.

Conflicting The human brain can’t hold on to two conflicting ideas without discomfort, and mixed emotions are common, so we employ compound expressions and mismatched displays. These usually send incongruous signals, and the more negative emotion often ends up being the one decoded. Examples of conflicting emotions can be seen with a twisted face, or the body swaying from side to side, as the desire to leave and stay creates conflict. Other restless behaviours are often evident when a person is conflicted, such as tapping and pacing. It can simply be that the words sound positive but the actions suggest otherwise (conscious v unconscious).

Confirmation look/glance Often performed after information has been given in a conversation, this look is a way of checking that the statement has been heard, understood or believed by those (or a particular important person) in earshot.  


Confusion From the receiver’s position, confusion equals mistrust; it’s a reason people find clowns or dolls unsettling, their expressions are fixed and unnatural, they are confusing. Displays of confusion include repetitive movement, shifting, fidgeting, and pacifiers, especially face rubbing. Other signs include eyebrow pinching and attempts to restore order. Dimitrius & Mazzarella state that the people pick up and put down items when experiencing confusion.

Connection A relationship in which a person is linked or associated with someone or something else. The presence of a Duchenne smile, allo-contact, an open posture, close proximity (including leaning) and easy eye contact are signs of connectedness as are mirroring and matching behaviours.

Contagion People pass feelings to one another. This emotional contagion can occur with every encounter experienced as we may feel an echo of another’s mood, something that can spread to others.

Contempt facial expression The feeling that a person or a thing is worthless or beneath consideration. This lack of respect can spark a smirk in which a corner of the mouth tightens (usually the left side). This one side’s cheek dimples, or pulls up toward the eye and ear. It may be accompanied by a scoff/snort, rolling of the eyes or askance look. The asymmetrical expression, often accompanied by anger, denotes a feeling of moral or social superiority and of not wishing (or needing) to engage. It’s often misread and misattributed, as the contempt is as likely to be for a situation as it is a person. It could also be a flirting face. 

Context Consider the environment or situation a behaviour is taking place in. The brain’s hippocampus provides a memory of context which is vital for emotional meaning. Context is usually needed for cues to be deciphered credibly. As with words, half of which are not heard or understood in isolation, images are ambiguous without context. Surroundings affect behaviour. Knowing this, an environment can be adapted or staged to elicit a elicit desirable response.

Contradictory signals Different contradicting messages can be sent simultaneously. The sender mat be feeling the mixed emotions but it makes decoding difficult for the receiver. The contradiction can result in fragmented actions and compound gestures.

Contrastors Words such as but, however, and nevertheless, are used to contrast two statements, the former setting up the latter, either as a way of softening the blow, adding authenticity or holding the floor but (see what I did there) they can end up weakening both statements.

Conscientiousness The personality trait of being careful or diligent, it implies a desire to do a task well. Conscientious people tend to be efficient and organised it is the case that conscientious people are generally better at reading body language.

Conscious The state or quality of awareness, human brains are working hard when engaging the conscious or executive function. For reasons of efficiency and expediency many skills are transferred below consciousness, it’s a purpose of learning. Most decisions are not made as a result of conscious thought. From first impressions, biases and gut instincts, people need to step back and engage conscious thought before making important decisions, when time allows.

Consequentialism Right or wrong depend on the consequences of an act, and that the more good consequences are produced, the better the act. Of all the things a person might do at any given moment, the morally right action is the one with the best overall results/outcomes.

Conventional crowds Brought together by an event, this is a group of people gathered for a purpose, or shared experience.

Cooperative side-by-side position When seated, the most cooperation can be expected from the people by your side, with the most from the person to the right (the right-hand man). When people know each other well they tend to sit side by side with no barrier.

Cornering By positioning themselves as a barrier, people can put an individual in a position from which escape is difficult without breaking social etiquette. It can be consciously manipulative, making the victim feel threatened or embarrassed, or unconsciously performer, with the victim stuck listening to the local bore or salesman.

Corpus callosum Joining the human brain’s left and right hemispheres is a band called the corpus callosum, connecting material that allows the two halves to communicate, an interaction that seems to be more profound in women and homosexual men, both of whom have a proportionally larger/thicker corpus callosum.

Cortex The cerebral cortex, also known as the cerebral mantle, is the outer layer of neural tissue or gray matter of the cerebrum of the human brain. The cortex is the area (of the brain) where thought, cognition and the processing of complex sensory information takes place.

Cortisol Closely linked with stress, cortisol is a hormone that works as a key player in the body's stress response. Often measured in research as an indicator of stress, it plays a vital role in the body's functioning.

Courtship displays Behaviours performed between mutually attracted romantic partners. Women use and initiate more courtship gestures than men, and are better as spotting sexual signals. Women also smile and laugh more than men during courtship. Human courtship follows a predictable sequence of actions. Among the many sexual signals are genital framing, closer proximity, more eye gazing, matching and mirroring, and synchronised movement.

Cowboy stance Palms inwards, with thumbs are tucked in to a belt, and the fingers pointing towards the genital area (framing it to draw attention).

Cultural Prevalence Some gestures have different meaning in different countries or cultures. The emblem 'thumbs up' for example, can mean 'good', 'one' or even be an offensive phallic symbol in some countries. 


Cranio-facial Of or pertaining to the cranium and the face.


Cross-gender behaviour Adopting a behaviour or aspect of the social role associated with the opposite sex. It could be adopting the clothing, hairstyle, gestures, speech patterns or gait commonly attributed to the other gender.

Cross-mirroring A form of mirroring performed when a similar but different behaviour is copied. For example, one person may cross their arms in response to another crossing their legs.

Crossing arms Used for many reasons, the arm cross is often taken as a barrier. It could be that the performer is cold, seeking comfort or adopting a habitual pose, but people often see it as defensive, which it can be. There are several variations: the position of the hands (fingers and thumbs), the intensity of the clasp, etc. Is the person reassuring themselves (tight grip) or might the hands be grasping the upper arms (attempting to intimidate).  


Crossing legs Traditional leg crossing is so common that its meaning is multiply, ranging from comfort to anxiety. The difficulty in making a quick getaway suggesting comfort, the body contact and protection aspects easing anxiety. Look for the direction of the knee and foot of the top leg, as this is likely to be directed towards a person of trust or interest. If legs suddenly cross or uncross it can be significant. Uncrossing legs can signal a negative emotion. 



Crotch display The thumb-in-belt cowboy stance is an example of drawing attention to the genitals. Manspreading, or legs apart, leaning back, is another crotch reveal.

Crying Producing endorphins for the purpose of self-anaesthesia, crying can provide a cathartic emotional release. Indeed, laughing, an extension of crying, also produces endorphins. Evident from birth onwards, crying can be attention seeking. In sadness, crying is typically accompanied by adaptors.

Cultural differences People are influenced by cultural forces such as political culture, socioeconomic situations and upbringing. Culture plays a role in how gestures and expressions are performed or suppressed in company. Personal space is also culturally influenced.

Curiosity An important quality relating to inquisitive thinking such as exploration, investigation and learning. It has been found that more curious people are better at reading facial expressions. Curiosity can be seen in eye behaviour that alternates between squinting and raised eyebrows/wide eyes as observation/listening takes place. Slow nodding, a tilted head and forward lean are other cues.

Curtsy A traditional gesture of greeting, in which a girl or woman bends her knees while bowing her head. By taking a lower position the receiver of the curtsy is offered an acknowledgement of their higher status.

Curved arm Often performed when in a seated position, the curved arm is a protective or distancing action with the elbow bent outward towards a potential threat.

Cut-off Blocking actions performed when stressed. This behaviour is done to reduce visual stimuli.
