Body Language of Pupillary Reflex, Pupil Dilation or Pupillary Constriction

by Chris • October 27, 2014 • 0 Comments

Body Language of Pupillary Reflex, Pupil Dilation or Pupillary Constriction

Cue: Pupillary Reflex

Synonym(s): Pupillometrics, Pupillary Constriction.

Description: The pupils of the eyes (the dark part of the eye) expand or contract dependent on the level of arousal. The pupils will automatically open up and allow more light into the eye on arousal or if we see something we like. Conversely, they will contract or close when we see things we don’t like. The pupils also respond automatically to changes in light. They open when it’s dark and close when it’s bright. This protects our eye from harm and increases our ability to see as the level of light changes.

In One Sentence: The papillary reflex refers to the dilation of the pupils in response to arousal.

How To Use it: Pupils react autonomically to light and emotion, thus it is not something that can be consciously controlled. However, one might artificially create situations which control the size of the pupil. For example, to create wide attractive pupils simply set up dates in low lighting conditions. Candlelight, for example will cause the pupils to dilate, thus making them more attractive. Women can make their eyes more dreamy in profile photos by digitally enhancing the size of their pupils. Likewise, matching your desires to reality will cause eyes to dilate naturally. In other words, finding a correct dating match, which really creates excitement, will naturally produce eyes that dilate, thus compounding the attraction effects.

Context: a) General b) Dating.

Verbal Translation: “When I’m aroused or when I like what I’m seeing, my pupils dilate and open wide so I can take it all in. When I’m turned off, or it’s bright, my pupils contract and take in less light.”

Variant: See Bedroom Eyes or Dialated Pupils.

Cue In Action: a) Mom’s eyes dilated to the max as she watched her newborn baby. a) During poker, he hit the card he liked and his eyes dilated widely, fortunately he wore sunglasses protecting them from sight. b) Her eyes dilated as she observed her muscularly sculpted boyfriend undress.

Meaning and/or Motivation: Pupillometrics is the study of pupil size in relation to emotion such as liking, interest, fear and dislike. Research has shown that young children have larger pupils than adults. This is probably a way for kids to appear more attractive and gain favour and attention. Watch how cartoonist’s habitually embellish the eyes of their characters to make them more appealing.

Pupil dilation can help a body language reader assess when emotion is taking place. Under stress or arousal of any kind, be it liking or visceral disliking, the pupils expand to permit more light to enter facilitating vision. This can include stress and fear due to lying, any other fearful situation and even attraction.

Conversely, the eyes contract due to not liking. This is an entirely autonomic process and not consciously controlled. When assessing someone on their pupil size, be sure to account for changes in ambient light, as the pupils will also respond to these changes.

Cue Cluster: Watch for congruency in body language to determine the meaning behind the pupillary reflex. Liking (dilation) would be coupled with head tilted to the side, open and relaxed facial expressions, smiling and loose body language. Disliking (contraction) would be coupled with head on, hard eyes, pursed lips, grimacing, eyebrows coming together and so forth. Also watch for changes in ambient light which will also determine the meaning behind the pupils.

Body Language of Pouting Lips or Lip Parting

by Chris • October 27, 2014 • 0 Comments

Body Language of Pouting Lips or Lip Parting

Cue: Pouting Lips.

Synonym(s): Lip Parting, Parting Lips, Bottom Lip Jut.

Description: a) When the lips form a pout or kiss and are pushed forward. Sometimes the cue is barely detectable where the lips only press together slightly. b) A facial gesture done by pressing the lips together and pushing them forward and crunching the eyebrows downward and inward as if in grief. A childlike facial expression where the bottom lip is pushed out.

In One Sentence: Pouting lips signals a negative though or the desire to kiss.

How To Use it: In dating, eyes to the lips of another coupled with lip pouting signals that one is ready to kiss. Women can use this gesture with good results at the end of a date to signal to their partner that they are ready for intimacy.

Pouting can also be used to manipulate the emotions of others. Children, like adults, can use the expression to show sadness. When viewed, others are likely to offer a caring response which can help you get what you want.

Context: a) Dating b) General.

Verbal Translation: a) “I really want to kiss someone, and I’m puckering in anticipation.” b) “I’m upset and it’s causing me grief forcing me to press my lips together.”

Variant: See Compressed Lips.

Cue In Action: a) She was aroused by Dave and found herself subconsciously pressing her lips together as if she was already kissing him – the anticipation was driving her mad. b) She was only 3 years old, but knew full well that if she pouted for long enough with sad eyes, Dad would do anything she wanted.

Meaning and/or Motivation: a) Lip puckering is a sexual cue, or desire to kiss, when in context.

b) Bottom lip jut is a negative thought indicator or that disagreement is present especially if accompanied by frowning, scrunched eyebrows, or other negative cues. This gesture is usually done by small children or by adults resorting to juvenile characteristics trying to secure affection, privilege, resource, or reward of some kind from another person. The lip jut is also called pouting and shows helplessness and lack of agency. This is the case when done by adults or children.

Cue Cluster: Lip puckering is usually associated with a) Other sexual cues of interest such as strong eye contact or eye to mouth, neck titled to the side and neck displays, lip licking and self touching or b) With hung or hunched shoulders, sad droopy eyes, scrunched up eyebrows, head down, verbal sighs and other helpless and dejected body language.

Body Language of The Parade

by Chris • October 27, 2014 • 0 Comments

Body Language of The Parade

Cue: Parade (the).

Synonym(s): (the) Catwalk.

Description: The “parade” occurs when a woman walks with an exaggerated swinging or rolling of the hips, back arched, stomach flat, breasts protruding, and head held high.

In One Sentence: The parade is a way to showcase sexuality to others.

How To Use it: Women can use the parade most effectively. For men, this is called swagger. If women wish to be noticed for their sexual assets, they should swing their hips in full view others, especially the ones they wish would notice most. This can be done by walking, but equally, can be done by rolling the hips in a fixed position. Men find an exaggerated parade to be highly visible and difficult to ignore so women can effectively use it to solicit men.

Caution is in order when using the signal since the parade is considered a broadcast signal, and therefore, difficult to anchor to a specific person. In other words, the cue casts a ‘wide net’ potentially drawing in men of lesser quality. However, the cues’ strength relies on this by drawing in many potential “male orbiters” whom are ready to do perform various services for a shot at romance. Women therefore, can use the signal to solicit general attention and then simply refuse those advances which do not meet her criteria.

Context: Dating.

Verbal Translation: “My hips are the focal point of my sexuality so I’m swaying them hypnotically up and down to draw your attention to my sexual bits – I sure hope you notice!”

Variant: The hips are a source of great power in female sexuality. Any draw to the pelvis indicates a desire to showcase a woman’s virility for the admiration of others. A bare midriff is particularity alluring because it exaggerates the hip-to-waist ratio. Incidentally, the tight flat stomach is the first casualty of pregnancy, which reduces the hip-to-waist ratio significantly. For this reason, a bare midriff is normally always reserved for women in the pre-childbearing years of the late teens and early twenties or those in peek physical fitness.

The same effect is accomplished with skintight dresses, and also bikinis or adornments such as waistlets and belly button piercings. They serve to draw the eye to the relative difference between the hips and waist. See Hip Tilt.

Cue In Action: She was newly single and feeling positive. You could tell she was prowling because she appeared confident and vibrant. When she walked, she commanded attention and the boys couldn’t help but look. It was obvious by the way she pranced that she was available and advertising.

Meaning and/or Motivation: Women naturally have wider hips than men in order to accommodate childbirth and it is the exaggeration of the differences between men and women the makes them sexy.

The parade is a way for women to attract attention by emphasizing their hips. Studies show us that women out of committed relationship naturally walk in this manner to attract attention.

For this reason, runway models are also instructed to walk with a hip tilt but in a much more exaggerated way. The hip emphasis posture is pervasive in fashion and advertising. We see women slouching to one side forcing their hips out to emphasize their curves, or walking in an exaggerated way, bouncing their hips up and down as if on a pendulum. Their hips are seen swaying high from the left side, dropping, then right side, dropping.

Picturing this parade or “cat-walk” in the nude and you get the sense that there is an obviously hypnotic purpose to the method. Because the hips move about a center pivot, the eye is drawn front and center to the woman’s genitals – acting like a beacon.

Out of consciousness the parade is not overt or striking, but now that you understand the characteristics, you can watch for it. Women can also roll their hips while standing. This draws attention to their pelvic region.

Cue Cluster: The gesture might be accompanied by a sideways glance and slightly parted wet lips, which could be unconsciously exaggerated by saliva or lipstick.

Body Language of Nose Crinkle, Nose Turning or Nose Shrug

by Chris • October 24, 2014 • 0 Comments

Body Language of Nose Crinkle, Nose Turning or Nose Shrug

Cue: Nose Crinkle

Synonym(s): Half-Sneer, Nose Shrug, Nose Turning, Nose Twitch, similar to a sneer.

Description: The nose momentary twitches to the side. Imagine a half sneer where the nose moves to one side rather than flexes in a full sneer.

In One Sentence: The nose crinkle signals a negative thought.

How To Use it: The nose crinkle is highly effective when used as a microexpression to show distain. Following a statement you disagree with, crinkle the nose by flexing the muscles around it forming an expression similar to disgust. This should be held only momentarily and follow the statement immediately. Since the cue is held for such a small amount of time, flashing it shows your true feelings, but since it’s not vocal or persistent, carries less weight and therefore puts you at less risk to scrutiny.

The signal can also be used between two parties whom wish to share a secrete dislike. For example, eye contact toward a friend coupled with a nose crinkle upon the entry of a new associate indicates dislike.

Context: General.

Verbal Translation: “I don’t like what I’m seeing or hearing and it’s forcing my nose to crinkle up as if I’m taking in a particularly offensive odor.”

Variant: The nose might do a full sneer with both sides of the nose flexing in unison.

Cue In Action: When it was suggested that the lunch hour be reduced from a full hour to half that in order to boost productivity, the associate shrugged his nose to the side in a half-sneer. It was obvious that he wasn’t in favour of the motion.

Meaning and/or Motivation: A signal of dislike or disbelief as if a person is moving their nose away from a disagreeable smell.

Cue Cluster: The nose turning is associated with other negative body language, watch for eyebrows to come together in grief, eye rolling, head turning away and eye contact toward supporters rather to the presenter of the information. The body might also be turned away from the presenter of the information.

Body Language Category: Automatic gesture, Closed facial gestures, Dislike (nonverbal), Leaked or involuntary body language, Microexpression, Microgestures, Micromessaging, Negative body language, Rejection body language.

Body Language of Nail Biting

by Chris • October 24, 2014 • 0 Comments

Body Language of Nail Biting

Cue: Nail Biting

Synonym(s): Fingernail Biting, Cuticle Biting, Nail Picking, Biting Fingernails.

Description: Biting or picking at the fingernails. Can be so sever that it results in bleeding, disfigurement, or unsightly nails down to the quick.

In One Sentence: Nail biting is a sign of insecurity, anxiety, discomfort and lack of self-confidence.

How To Use it: Nail biting is a negative nonverbal cue. It is not advised that one should do it unless one wishes to feign anxiety.

Context: General

Verbal Translation: “I’m suffering from extreme inner turmoil and anxiety. I need to pacify myself by reverting to childlike suckling or mouthing of my fingers, as a substitute for my mother’s breast.”

Variant: Any object to the mouth indicates a need for to pacify including, thumb sucking, sucking on pens, chewing on the arms of the glasses and sucking on a cigarette. Other tension relieving activities include adjusting clothing when it’s not needed, playing with an object, running fingers through the hair and shaking a shoe.

Cue In Action: Gordon Brown, the UK Prime Minister, has the look of a frequent nail bitter. He likely suffers a great deal of internal stress.

Meaning and/or Motivation: Nail biting is a form of emotional body language, and when present, is usually habitual because of its origins. The habit which is highly unsightly screams “I am insecure.” These types of gestures are called “pacifying behaviours” because they are designed to reduce anxiety when exposed to something distressing.

Nail biting signals apprehension, anxiety, discomfort and a lack of self-confidence. Putting any object in the mouth is a signal of inner turmoil and negative feelings. The mouth is utilized as a source of pacifying as the breast was during infancy and indicates a need to be reassured. Biting the nails also serves as a mouth cover which blocks the mouth from the sightline of others creating additional security and secretiveness, but also creates suspicion in others.

The astute nonverbal reader will carefully observe a person for their unique mannerisms as they are difficult for people to control and hide. This makes a quick check of the nails and fingers for excessive chewing particularly important in gaining insight into a body language target. Nails that appear wider than they are long, called ‘brachyonychia’ is a sure sign that a person doesn’t feel at ease and regularly suffers from extreme tension. A thumb that is frequently sucked might appear worn or have chew marks or indentations.

Cue Cluster: Generally, nail biting is a stand-alone cue that needs no additional reinforcement to have true meaning – though one should watch for additional cues of discomfort and desire to pacify.

Body Language Category: Blocking or Shielding, Displacement behaviour, Emotional body language, Idiosyncratic body language, Leaked or involuntary body language, Low confidence body language, Negative body language, Nervous body language, Pseudo-infantile gestures, Pacifying body language, Security blankets, Stressful body language, Suspicious body language, Worry body language or worry.

Body Language of Micronodding

by Chris • October 24, 2014 • 0 Comments

Body Language of Micronodding

Cue: Micronodding

Synonym(s): N/A

Description: A barely perceptible dip of the head usually at the end of a sentence or statement with a return to the upright position.

In One Sentence: Micronodding tells others that concealed agreement is present.

How To Use it: Use the micronod to encourage others to speak without signaling a desire to cut them off. A micronod is a way to tell others that you agree with them without being overt. It’s also useful when you don’t want to be called upon to add anything new to a conversation – a silent agreement.

When you boss is speaking, a micronod can signal that you and he are on the same page. The same works between spouses and friends. A micronod can also substitute for actual listening. A few nods here and there will show that you are “listening.” Most will read this as “I understand.”

The micronod can also punctuate sentences, especially when they are provocative. In other words, a micronod is a way to throw down a challenge. This will help assert your points and show others that you are confident in what you are saying.

Context: General.

Verbal Translation: a) “I’m fully committed to my statement and nod slightly to show that I’m willing to stand behind it. I issue my confidence in my idea as a challenge.” b) “I agree with what you are saying, but don’t want to be known for it so I’m doing my best to stifle it.”

Variant: See Head Nod.

Cue In Action: George Bush habitually micronodded his head while uttering the words “make no mistake.”

Meaning and/or Motivation: A micronod is usually aimed at the listener as a slight attack and commitment to what is being said.

Other times, a micronod signals covert or reserved agreement which is stifled, but still manages to leak from the body. In this form, it signals that a person does not wish to be known for agreement. Take for example a micronod while agreeing that the team of which you form a part, isn’t as superior to the other team. While you might consciously or even subconsciously agree with the statement, you wouldn’t want to overtly endorse it to betray your teammates or admit weakness.

Cue Cluster: N/A

Body Language of Lip Chewing or Chewing The Lips

by Chris • October 23, 2014 • 0 Comments

Body Language of Lip Chewing or Chewing The Lips

Cue: Lip Chewing or Chewing The Lips

Synonym(s): Chewing The Lips, Biting The Lip, Lip Nibble, Cheek Biting, Lip-to-Lip Bite, Lip Chewing.

Description: a) The lower or upper lip is bitten. b) The lips are brought tightly together against the teeth as if the lips are biting each other in a lip-to-lip bite. It is visible as the lips come inward slightly. c) The teeth bite the insides of the cheeks or the corner of the mouth visible as the mouth is contorted sideways to bring the cheek toward the teeth. The lips may purse and also bounce up and down as if chewing food.

In One Sentence: Lip chewing is a negative thought indicator.

How To Use it: One should avoid chewing on the lips as it tells others that you are suffering from negative internal emotions. Feigning or actual negative emotions, on the other hand, can incentivize others to offer care and support. Therefore, the signal has applications as an honest gesture of suffering.

Context: General.

Verbal Translation: “I’m pacifying and punishing myself due to the negative thoughts and feelings I carry around with me.”

Variant: When pacifying is necessary, people find comfort in biting other objects such as pencils, their fingernails or the stems of their glasses. They may also pull and pinch at themselves. See Lip Biting or Biting The Lip, Lip Picking.

Cue In Action: She was on antidepressant medication and seeing a shrink but even in benign social situations, she would be found fretting as she chewed the insides of her cheeks.

Meaning and/or Motivation: Sucking, plucking, picking or chewing the lips, rubbing them with a finger or thumb are all forms of auto touching. Confident individuals would never consider using this type of behaviour out of insecurity.

When someone feels anxious they habitually find an outlet via chewing. Usually this is a pencil or pen, fingers or finger nails but when nothing else is available or as a default, the lips or sides of the mouth are chewed.

This is a subconscious return to the mouthing of a breast and reminds adults of the tactile pacifier which it served in infancy. The lips often serve as outlets for anxiety because they are always readily available unlike a pencil or other soother. Lip and cheek biting can also be a form of self-restraint, though usually not if it is done persistently, but rather suddenly in response to a certain message or stimuli. Alternatively, lip chewing can signify the desire to act out aggressively where the pain is turned inward rather than expressed outwardly.

Cue Cluster: When someone is anxious, expect their bodies to reflect a desire to turn inwards such as eyes turned downward and glazed over, head down and the shoulders slump. Emotional downtime, when people escape inward while in public, is characterized by pauses in breathing, subtle chewing of the lips, or very brief eye freezes or glazing over.

Body Language of The Hip Tilt

by Chris • October 23, 2014 • 0 Comments

Body Language of The Hip Tilt

Cue: Hip Tilt

Synonym(s): Hip Canting, Pushing A Hip Out, Hip Swing, Hip Jut, Hip Sway, Hip Roll, Pelvic Tilt, Rotating The Pelvis, Tilting The Pelvis, Rolling The Pelvis, Pelvis Roll, Wiggling.

Description: A female posture. a) Women can be seen slouching to one side forcing their hips out to emphasize their curves. b) While sitting or standing, a woman may subtly roll her pelvis to draw attention to her sexuality.

In One Sentence: The hip tilt is a feminine gesture meant to emphasis the allure of wide childbearing hips.

How To Use it: Women may cant their hips to the side to showcase their fertility to men. In a dating context, dropping one hip emphasizes curves that separate men from women. While walking, a hip sway is particularly effective in attracting or maintaining male attention. Girls are known to adopt this posture early in life which may be the result of modeling older women, or perhaps a genetic predisposition.

Context: Dating.

Verbal Translation: “My hips are wider than yours and I want to draw male gaze so I’m going to exaggerate and draw attention to my wider, sexier hips, by titling to the side or walking with an exaggerated swing.”

Variant: See Parade (the).

Cue In Action: She was it. She made her way across the room to the bar to order a drink and every man’s gaze was drawn in by her cat-walk. Her hips moved hypnotically from side-to-side with each step. She owned the room in her little black dress.

Meaning and/or Motivation: Women naturally have wider hips than men in order to accommodate childbirth and it is the exaggeration of the differences between men and women the makes this sexy.

The hip emphasis posture is pervasive in fashion and advertising. We see women slouching to one side forcing their hips out to emphasize their curves, or walk in an exaggerated way, bouncing their hips up and down as if on a pendulum. Picturing this parade or “cat-walk” in the nude and you get the sense that there is an obviously hypnotic purpose to the method. Because the hips move about a center pivot, the eye is drawn front and center to the woman’s genitals which act as a beacon. Studies show us that women out of committed relationship naturally walk by exaggerating the hips to attract attention.

It has been noted that even girls as young as five to six years of age will “strike a pose” by jutting their hips out to the side. This suggests that its origins are innate, though it could also be mirrored from fashion and magazine advertisements. Curiously, boys are rarely seen performing this posture unless in jest, suggesting it’s sex specific.

Cue Cluster: The hip tilt gesture might be accompanied by a sideways glance and slightly parted wet lips, which could be unconsciously exaggerated by saliva or lipstick. Also watch for back arched, stomach flat, breasts protruding, and head held high.

Body Language of Hard Swallow or Swallowing Hard

by Chris • October 22, 2014 • 0 Comments

Body Language of Hard Swallow or Swallowing Hard

Cue: Hard Swallow or Swallowing Hard

Synonym(s): Swallowing Hard

Description: When the throat swallows harder than normal, possibly even gulping air along with saliva. Sometimes it is audible, but usually only barely.

In One Sentence: A hard swallow indicates stress.

How To Use it: Avoid using the hard swallow unless you want others to see that you are suffering from stressors.

Context: General.

Verbal Translation: “I’m stressed and my swallowing has become conscious and controlled. I do a poor job of it due to stress induced dryness.”

Variant: N/A.

Cue In Action: While presenting his throat dried up. No matter how much water he drank, his mouth still went dry. When it was time to decide over the investment, his financiers were contemplating, and he was audibly gulping as he hard swallowed.

Meaning and/or Motivation: The hard swallow is a high stress or embarrassment indicator due to low saliva production as the fear response of a person is activated. It is usually involuntary.

In the right context, the hard swallow sometimes indicates that a lie is being told, but it is more reliably, a general signal of high stress.

Cue Cluster: Watch for touching the face and neck, pacing, eyes darting and blushing or blanching.

Body Language of Hand Covering or Cupping The Mouth

by Chris • October 22, 2014 • 0 Comments

Body Language of Hand Covering or Cupping The Mouth

Cue: Hand Covering or Cupping The Mouth.

Synonym(s): Cupping The Mouth, Mouth Slap, Slapping The Mouth, Hand Slapping The Mouth.

Description: a) One or both hands quickly come up to the mouth covering with both palms. b) One hand quickly comes to the mouth palm open against the mouth in a slapping motion.

In One Sentence: Hand to the mouth is a signal of disbelief, shock, mischief, or the desire to reclaim misspoken or damning words by jamming them back in.

How To Use it: Bring the hand to the mouth to show shock or surprise. It is useful to show others that you can’t believe what you just heard or saw. When you say something inappropriate, bringing the hand to the mouth shows other people that you wish to take the words back and wish to prevent any other hurtful words from coming out and doing more damage.

Context: General.

Verbal Translation: a) “I’m scared or surprised by what I’m seeing so I’m covering up my surprised gaping mouth.” b) “I can’t believe what I said or what I heard you say and am covering my mouth in effort to jam the words back in or prevent any more offensive words from coming out.” “My hand is slapping my mouth to prevent me from saying things I shouldn’t and to jam the things I already said, back in.”

Variant: See Hand To Mouth, Hand To Nose, Hand To Eye Gesture, Hand To Cheek. Other variants to the mouth slap include a closed fist against the mouth, a single finger over the mouth in a shh-ing gesture (self silencing), finger in the mouth (sucking for soothing), or the hand-to-mouth in a fake cough.

Cue In Action: a) A bicyclist darted through the intersection and ran head-on into oncoming traffic smashing into the hood of a car. The bystanders were stunned. One of the women was covering her mouth in horror. b) The six year old accidentally let out a cuss word in front of her parents. She quickly slapped her mouth in shame. c) Wendy was a chatter box, and the worst at keeping secrets. She was talking away at the cafeteria when she blurted out that she had an outfit all set out for the special occasion on Friday night. Realizing what she had done, she slapped her mouth with her hand. The birthday party was to be a surprise and the birthday girl was right there at the table.

Meaning and/or Motivation: Mouth covering is a way to reduce the pain of telling a lie. In this case, it is so as to “speak no evil.”

Small children perform a full cover and even slap their mouths when they say something they shouldn’t. However, the mouth slap usually becomes a vestige to other minimized gesture such as the hand to the chin, or the hand coming to the corner of the mouth, or several fingers seemingly busy playing in front of the mouth.

When in the right context, hands to mouth or mouth slapping is a clue to deception and a desire to prevent being detected or revealing too much information. Grown adults will sometimes cup their hands to their mouths like children in effort to “jam the words back in their mouths” but usually use more subtle gestures such as “talking through their hand” which is a gesture done by placing a finger softly over their lips.

Talking with one’s hand covering the mouth, “talking through the hand,” or resting the hand around the mouth by wrapping the fingers around the top, are significant clues indicating insecurity.

Subconsciously, hand-to-mouth gestures leads people to distrust others, and see them as less honest overall. The gesture can be done with a fist, a finger, or a ‘shushing’ motion with the index finger vertically placed over the lips. Other times the subconscious mind is so powerful that the hand comes up and slaps the mouth, but to cover this ‘tell’ up, a fake cough is added.

What starts off as a quick mouth slap movement to the mouth when lying (or swearing) in children, slowly becomes a touch to the corner of the mouth. Later, restraint forces the finger to the side even further and then instead of touching the mouth it touches the side of the nose instead. As people age, they become much more difficult to read. By logical progression, the hardest to read of all are sixty-year-old politicians!

Cue Cluster: The mouth usually gaps open with eyes widening or the mouth jams shut with the head tilted down or away, depending if shock is experienced or words have accidentally spilled out. Sometimes the hands come to the head rather than the mouth during shock. Usually the facial expression is one of surprise. When someone says something regrettable they might blanche or blush, avert their eyes, slink down in embarrassment, seek exits and become quiet. When the hand comes to the mouth in more abbreviated forms, the eyes will also avert, a person may begin to fidget or squirm, touch the neck or nose as well as additional emotional cues of discomfort.
