Predict People's lie by their gesture

The speed of some gestures and how obvious they look to others is also related to the age of the individual. For example, if a five-year-old child tells a lie to his or her parent, the mouth will be deliberately covered with one or both hands immediately afterwards (Figure 6). The gesture of covering the mouth alerts the parent to the lie and this gesture continues to be used throughout the individual’s lifetime, usually varying only in the speed at which it is done. When the teenager tells a lie, the hand is brought to
the mouth like that of a five-year-old, but instead of the obvious hand slapping gesture over the mouth, the fingers rub lightly around it (Figure 7).
This mouth-covering gesture becomes even more refined in adulthood. When the adult tells a lie, his brain instructs his hand to cover his mouth in an attempt to block the deceitful words, just as it does for the five-year-old and the teenager, but at the last moment the hand is pulled away from the face and a nose touch gesture results (Figure 8). This gesture is nothing more than the adult’s sophisticated version of the mouth-covering gesture that was used in childhood. This is an example of the fact that, as an individual gets older, many of his gestures become sophisticated and less obvious, which is why it is often more difficult to read the gestures of a fifty year-old than those of a much younger person.

A Framework for understanding

PSYCHOLOGY- A FRAMEWORK FOR UNDERSTANDING VERBAL AND NON-VERBAL COMMUNICATION

As we approach the end of the twentieth century, we are witnessing the emergence of a new kind of social scientist-the non-verbalist. Just as the birdwatcher delights in watching birds and their behaviour, so the non-verbalist delights in watching the non-verbal cues and signals of human beings. He watches them at social functions, at beaches, on television, at the office or anywhere that people interact. He is a student of behaviour who wants to learn about the actions of his fellow humans so that he may ultimately learn more about himself and how he can improve his relationships with others.
It seems almost incredible that, over the million or more years of man’s evolution, the non-verbal aspects of communication have been actively studied on any scale only since the 1960s and that the public has become aware of their existence only since Julius Fast published a book about body language in 1970. This was a summary of the work done by behavioural scientists on nonverbal communication up until that time, and even today, most people are still ignorant of the existence of body language, let alone its importance in their lives...
Charlie Chaplin and many other silent movie actors were the pioneers of non-verbal communication skills; they were the only means of communication available on the screen. Each actor was classed as good or bad by the extent to which he could use gestures and other body signals to communicate effectively. When talking films became popular and less emphasis was placed on the non-verbal aspects of acting, many silent movie actors faded into obscurity and those with good verbal skills prevailed.
As far as the technical study of body language goes, perhaps the most influential pre-twentieth-century work was Charles Darwin’s The Expression of the Emotions in Man and Animals published in 1872. This spawned the modern studies of facial As we approach the end of the twentieth century, we are witnessing the emergence of a new kind of social scientist-the non-verbalist.

As far as the technical study of body language goes, perhaps the most influential pre-twentieth-century work was Charles Darwin’s The Expression of the Emotions in Man and Animals published in 1872. This spawned the modern studies of facial expres-sions and body language and many of Darwin’s ideas and observations have since been validated by modern researchers around the world. Since that time, researchers have noted and recorded almost one million nonverbal cues and signals. Albert Mehrabian found that the total impact of a message is about 7 per cent verbal (words only) and 38 per cent vocal (including tone of voice, inflection and other sounds) and 55 per cent non-verbal. Professor Birdwhistell made some similar estimates of the amount of non-verbal communication that takes place amongst humans. He estimated that the average person actually speaks words for a total of about ten or eleven minutes a day and that the average sentence takes only about 2.5 seconds. Like Mehrabian, he found that the verbal component of a face-to-face conversation is less than 35 per cent and that over 65 per cent of communication is done non-verbally.
Most researchers generally agree that the verbal channel is used primarily for conveying information, while the non-verbal channel is used for negotiating interpersonal attitudes, and in some cases is used as a substitute for verbal messages. For example, a woman can give a man a ‘look to kill’; she will convey a very clear message to him without opening her mouth.
Regardless of culture, words and movements occur together with such predictability that Birdwhistell says that a well-trained person should be able to tell what movement a man is making by listening to his voice. In like manner, Birdwhistell learned how to tell what language a person was speaking, simply by watching his gesture...
