The two left the market and returned with a full load, although there was no big leak in the pickup, it felt very good, especially the black-fleshed old sandalwood, which was also a rare medicine.

After eating at noon, I was just about to rest when I returned to the hotel, and my mobile phone rang, it was Jiang Zhenyu?

"Hey, it's me, yes, in the capital, okay, see you in the afternoon. ”

Wen Yiming hung up the phone, and Jiang Zhenyu was a little curious and took the initiative to ask to meet, saying that he had something to ask for. Let me go straight to the university at two o'clock in the afternoon and listen to his lectures.

Last time, the two cooperated quite tacitly, although Wen Yiming was reluctant to get too involved in criminal cases, but he was still very interested in understanding psychology and micro-expressions, so Jiang Zhenyu was a good channel.

When I came to the university, I asked to find the lecture hall, and I started with it, and sat down at the end and listened and talked.

Jiang Zhenyu didn't see Wen Yiming, today is an open class, turn on the projector, a picture of don't lie to me appeared on the big screen, and the students were quiet in an instant.

"I believe that when you see this picture, everyone should know what it is? Yes, it's a popular American drama, don't lie to me, today I want to continue to share some knowledge about micro-expressions and micro-reactions. ”

Jiang Zhenyu is polite and very professor-like: "Many students should have watched this American drama, and the protagonist in it, Dr. Letterman, is amazing, and he can learn a lot of secrets by looking at other people's faces in just a few minutes." I'm sure everyone thinks it's incredible, don't you want to have this ability too?"

"Yes!"

Many people in the audience replied with a smile, Jiang Zhenyu waved his hand and said: "Then today I will use a psychological perspective to analyze a few obvious mistakes in Don't Lie to Me!"

"What? There are still mistakes in American dramas?"

"Wouldn't it? I heard that Don't Lie to Me won a lot of awards that year, and the screenwriter is Dr. Aikman himself, who is the founder of Micro Expressions!"

"Don't mess around, listen to what he has to say!"

There was a commotion in the audience, and then gradually quieted down, and hundreds of pairs of eyes stared at Jiang Zhenyu curiously, seeing how he was going to explain?

"Everyone, please look at the screen, which records some of the most widely circulated polygraph standards for micro-expressions, and I will explain them in turn and tell you the real reasons for them. ”

"First appeared in the first twenty minutes of the first episode of the first season, and that's it!"

Dr. Letterman went to investigate the case and met an abusive male prosecutor, who later discovered that the prosecutor was having an affair with a female assistant. This is the expression, touching the nose with your hand, and the translation below says that this is the classic lying expression. ”

"The reason is that there is a cavernous body in the nose, and once you lie, it will itch, and people instinctively touch it!"

Jiang Zhenyu turned around and asked with a smile, "Everyone present knows what cavernous tissue is, right?"

"Hahaha!"

Everyone smiled, and Jiang Zhenyu continued: "This is the most widely circulated reason on the Internet, but it is also the most confusing! As long as people with medical knowledge know that after the nose is dissected, there will be no so-called cavernous tissue at all!"

"Its scientific name is the coronary microvascular plexus, which is a dense number of tiny blood vessels that have nothing to do with the corpora cavernosa. So even if it's a lie, it won't itch, this argument doesn't hold water!"

Hearing this, suddenly a boy couldn't help but ask loudly: "It's true that many times I like to touch my nose after lying, why do you say?"

"Oh?" Jiang Zhenyu smiled: "It seems that this classmate has this habit, everyone remember!"

Everyone burst into laughter, and Jiang Zhenyu explained: "In psychology, this is called a comfort response, and this kind of self-comfort usually occurs when a person's behavior violates the truest reaction in their heart, or moral standards. Sometimes touching the nose, or touching the face and neck, depending on the person's habits, the part is different. ”

"I've studied the original English video, and it's not about the corpora cavernosa, it's about a tissue that resembles a blood vessel. It may be that the subtitle group has no medical expertise, and it is directly translated into cavernosa, and this is not Dr. Letterman's fault!"

"I see!

"Makes sense, I was weird when I heard that English word!"

After whispering in the audience, he quieted down again, looking forward to Jiang Zhenyu's next topic.

"First of all, let me explain the principle of micro-expressions and micro-reactions, a discipline founded by the American anthropologist, Dr. Paul Aikman. In order to study this law, he went to live in a primitive tribe for three years, sorting out and collecting the most primitive expressions. ”

"Look at this picture, what is your expression?"

"Angry!" many people replied immediately, Jiang Zhenyu played another picture, and the cheetah put on the same grinning expression.

"It's sadness, covering your eyes with your hands, psychologically an avoidance reaction and not wanting to face reality. If you look at the monkeys, they also use the same expressions to convey sadness. ”

Jiang Zhenyu concluded: "Man is a high-level animal, we are social, but the most primitive expressions and reactions have not changed. It is the result of millions of years of evolution, which has been imprinted in the genes and passed down from generation to generation. ”

"People who have really been exposed to the study of micro-expressions will find that the so-called micro-expressions are not a single link, and it is impossible to determine the murderer with a few casual glances in film and television dramas, that's a joke!"

Jiang Zhenyu said: "This is a very serious discipline, it has its rules and principles, such as determining the baseline of expressions, such as setting questionnaires, such as how to screen real and effective information, all of which have strict principles, not child's play." ”

"So you look at the so-called ten principles of polygraphy, one shoulder shaking - not being confident, looking into the other person's eyes - lying, stiff repetition of questions when answering - typical lies, raising the chin - very embarrassed, looking to the right is reminiscing, looking to the left is thinking about lies, and so on. It is not a single judgment, but also a comprehensive judgment can only be made in combination with the context and problems at the time. ”

"Especially this principle of eye movement, science does have this theory, but it is not what is on the left, what is on the right. It is developed according to the working principle of the left and right hemispheres of the human brain, and different stimuli will produce different results, which cannot be generalized!"

"The real micro-expressions are produced by the movement of hundreds of muscles in the face, the upper eyelid and pupil, the lower eyelid and the brow, all in synergy. And the real micro-expressions will not hold *** at most, and it may be a deliberate performance for more than two seconds. ”

"For example, surprise lasts for a quarter of a second at most, and then it can be transformed into joy or disgust, depending on the source of the stimulus. ”

"It's an antelope grazing, and suddenly it raises its head, its ears keep moving, its body tenses, its nostrils open, and its eyes start to roam around, why?"

"Because danger is approaching!"

Jiang Zhenyu pointed to the audience and said: "Yes, this is the common feature of all creatures, once you find that there is a stimulus source in the outside world, you instinctively distinguish whether it is good or bad." If it's a good stimulus, the surprise will immediately turn into joy. ”

"For example, if you have a birthday, your friends start to pretend to forget, and suddenly come out to celebrate the moment you go home and open the door. You are first surprised, then excited and joyful. ”

"If the stimulus is malicious, it will turn into disgust, and there are four stages, different levels and lows. If the stimulus continues to get closer, the disgust will turn into anger, you will get angry, you will block it through sound, and you will even have physical movements. For example, if you meet a thug in the elevator girl, and he behaves badly, you will yell at him, right?"

Everyone in the audience nodded involuntarily, deeply attracted by Jiang Zhenyu's speech, and became more and more curious.
