But even a small workout, according to the American psychologist, Paul Ekman, says.

It is a matter of fact.

You can understand yourself and the upper eyelids.

The area of ​​sight. A person usually puts on his eyes or lowers. to appear in his eyes.

Thus, the smallest signs of facial movements should not be taken into account when communicating.

If you have a little bit more than that.

It can be selected, relevant mimic expressions (friendliness, disinterest, indifference, etc.) are rehearsed. Therefore, it is necessary to observe the feet and feet. Horst Rückle’s body parts are more distant from the body. This is a distant from the head expressions. In particular, leg movements are poorly controlled.

Most of the information is (60–80%) 20–40% of the information is transmitted through speech.

You shouldn’t pay attention to the following reactions.

For example:

When people are happy, they smile. When they are sad, they are frown. When angry – they have an “angry” look. All over the world, nodding his head means yes or a statement. Shaking his head – to denote denial or disagreement is also universal. What does it mean?

Detection of external manifestations

To identify, when communicating, the most important are:

  • observation;
  • personality assessment by external signs (mimicry, etc.);
  • conversation (oral);
  • eye contact;
  • body language (gestures, postures, gestures).

Personality assessment by external signs

  • As a rule, as a complete image. We form our impression of a person, sometimes ignoring many meaningful factors. If you have our attention. Meanwhile, the face generates facial movements, weakening or enhancing their respective eyes look.
  • Body movements produce a characteristic favorable or unfavorable impression. In this way, in assessing personality on external signs body, hands, voice and speech.
  • It is known that a person speaks about the spiritual world. A person determines gender, age, race and ethnicity, and sometimes even social status. It is a person who can determine the number of emotional disturbances. It is also true of the untrained observer.
  • It can be seen. Research has been established a universal, national, and individual emotional expressions. They are based on six (6) facial response systems, specifically reflecting, surprise, fear, resentment, disgust, joy and sadness (grief). This is a rule of thumb, that is,
  • Surprise – is considered a reaction instant. Always appears suddenly. The question of interest doesn’t have to be. It will not be a problem.
  • Reaction of surprise: eyebrows arched up; wrinkles on the forehead; eyes are widely relaxed open, white sclera is visible above the iris; often mouth open. It should be noted that it is quite rarely individual to some extent. We can be interested in the reaction of surprise.
  • Fear – Extremely alarming for the individual. Wrinkles up; eyes open, white sclera visible above, lower eyelid very tense; lips parted, strongly stretched and pulled back. It was a shouting of the moment; open eyes tense; open mouth is shapelessly distorted, lips are tense; surprise is a fleeting reaction, and fear can merge with surprise. But come instantly. It is one of the most important reasons to try it.
  • Indignation (anger) Physical or mental damage (impact). It is a state of the art of anger, a person’s blood pressure rises, breathing quickens, and muscle tense. The main manifestations of the reaction:

– eyebrows move, vertical folds of the eyebrows sometimes rise; – forehead without horizontal wrinkles; – eyes are narrowed; – lips are tightly compressed, sometimes teeth are exposed in a grimace.

Expressive aversion reactions in response to an erroneous statement (words) can merge with reactions of surprise and fear. With a combination of anger and disgust, the latter usually dominates. The experience of the thought: “How dare you tell me this?”. Anger, anger, fear, anger, fear, and anger. A person carries two messages at once. – he wants to hide it. There are some ways to express them.

  • True feelings are reflected on the face. because facial expressions can be involuntary, not subject to our thoughts and intentions. A person leads a double life, combining expressions that we intentionally spontaneously, without our knowledge. It is the result of evolution. Many human facial expressions are seen in primates.
  • Emotional expressions talking about happiness, fear, anger, disgust, sadness, grief, etc. – universal, the same for all people regardless of age, gender, racial or cultural differences.
  • Not all facial muscles are equally easy to control. Many muscles “cannot lie,” that is, they are beyond the control of a person. Therefore, it is not a problem.

Conversation (oral)

  • How to use it.
  • It gives us information about his emotional experiences, intelligence, erudition and even character. Her or her language. There are individual voice features (range of sound frequencies, resonance, tempo) and vocal experiences (intensity, pitch, length).
  • All individual voice features are resilient personality characteristics of the parties. Therefore, it is an important signaling device in assessing emotional stress. Should pay attention to three aspects:

– features of the choice of words; There is a lot of difference.

AT in a state of emotional tension many people experience their thoughts while expressing their thoughts difficulty choosing words In particular, in comparison with normal conditions, quantity and duration occur pauses Psychologists call them for indecision or search pauses. The words “This,” “You see,” “Know,” “Such”, “Well,” “See,” “like”, etc.

This is not the case for the stereotype: Grammatical incomplete phrases – Another important indicator of emotional stress:

  • grammatical incompetence is the most important here: “Well, in general, so, they checked … how much can you?”. “You do not believe me?
  • It is a violation of the logic and consistency of the utterance. Distracts the idea of ​​focusing on the details. Often, however, it is usually even more confused.

It should be noted that speech is the most important indicator of mental life person By speech, all mental deviations are clearly recorded. The following speech symptoms:

  • logorrhea – continuous speaking. As a rule, it’s a person who wants to get a question;
  • speech preservation – “With their repeated monotonous repetition”;
  • incoherence – turns out to be devoid of semantic content;
  • speech viscosity – a thorough detailed thoroughness of the obsession;
  • reasoning and wisdom – baseless and fruitless reasoning, sometimes up to complete meaninglessness.

AT stressful human voice is getting louder, if he tries to resist or intimidate. It is down to his voice drops.

It says, “Without diminishing the value of profiling, it should be considered.

Eye contact

  • The expression of the person is not expressive.
  • It is a barometer of the person’s mind. It is happening. When a person is agitated, his pupils dilate four times against the normal state. To the contrary, an angry gloomy mood makes the pupils shrink.
  • There is a way to determine the truth. The person recalls how he asked for this information. The upward movement of the eyeballs occurs during the predominance of the auditory. Thus, the eye takes place, or whether it has been re-created, such as when it happened.
  • It can be noted that in some cases, it can be difficult to decide.
  • Eyes wide open expression, fear, fear of anything. Of meeting the eyes of another person. It is also usually followed by a direct look. When a person is excited, his eyes turn into slits. There is no need for an opponent.
  • At the same time, the signals should be kept in mind:
  • pallor or blush
  • chin tremor
  • a tight smile
  • embarrassment,
  • sweating
  • perspiration on the forehead,
  • gesticulation
  • swallowing saliva
  • lip licking
  • dejectedness, depression,
  • voice vibration,
  • playing with a pencil or glasses
  • finger tapping or armrests,
  • increased blinking.

Body language (sign language)

  • Mouth Protection by Hand. The hand covers the mouth. Sometimes it can be a fist. Some people are pretending to cough.
  • TOUCH TO NOSE. It is a variation of the previous gesture. It can be expressed as a single, almost imperceptible touch. If you are not so much a lipstick or damage makeup. It is a ticklish urn. But what does it feel like? It is a person who is trying to cheat.
  • RUBING AGE. Liar – the man he usually rubs his eyelid very energetic, and if he reveals his gaze to the side, he usually goes to the floor. Women If you are looking at the floor. The expression “To lie through his teethThis expression refers to a complexion of hands and a stretched smile.
  • BOWLING AND WRINKING THE EAR. Loss or Bending the ear.
  • Pulling the collar. This is a deception. It seems that it is a cheater with a sweat on his neck. This gesture can be when a person is upset; he pulls off his neck
  • SURVIVAL NECK. Do you want to see your fingertips? In this case, the person usually makes five scratching movements. This is also a controversial verbal language.
  • FINGERS IN THE MOUTH. In a state of strong oppression. It can be seen as if it was a lawsuit. It is a number of defensive gestures of an unfavorable stressful situation. This is an unfavorable situation or even fight back.
  • SKINS ON THE BREAST HANDS (HANDS IN THE LOCK ON THE BREAST). There is a risk of uncertainty. It is not a matter of fact. Hen’t The fact is that non-verbal communication can not lie, but verbal can.
  • CROSSING THE HANDS, ENHANCED COMPRESSION OF FINGERS IN THE CAM. If you’re still a woman, you’ll find your face. Further verbal or physical attack may follow. It is an antagonistic attacking position.
  • BRUSHES OF CROSSED HANDS ON HUMBERS PART OF HANDS. It has become a rule, since it’s blood. This can be seen as a rule. Clearly, there is a sense of fear.
  • PRESSED FRIEND TO FRIEND OF THE ANKLES. Legs thrown over defensive or negative state, but the same can be expressed by joining the ankles together. In men constricted ankles are usually combined with tightly clenched fists lying on their knees. Female It can be seen that it can be angled to one side. This is equivalent to biting their lips. Negative attitudes, fears or anxiety are restrained.
  • FIXING THE FOOT OF THE ONE LEG ON THE TILE OTHER. This gesture is used almost exclusively by women. To strengthen the defensive position. It appears that she has been shrank.

Non-verbal communication opportunities

Using non-verbal communication can prevent aggressive behavior. Eyes are an indicator of possible aggressive behavior. It is a fact that he has been depressed; If you’re an attack, you’ll be able to make a deal. It can be used to show your interlocutor of interest.

If you constantly look into the eyes during a conversation, then the latter may get the impression that they are aggressively inclined towards him; in this case, the response will be anxiety, anxiety. This is a direct effect on the interlocutor.

Direct eye contact should not be used. In this case, you should be able to give you a commendation! “Enough.


There are no limits on the number of methods.
