Chapter 309 Micro Expressions (1)
While the man with black-rimmed glasses was sitting in the interrogation room and chatting with Ju Yi about his past, Professor Yang Yi and another disciple were sitting outside the interrogation room, watching Ju Yi's micro-expressions through a special instrument.
This instrument clearly recorded Ju Yi's emotional fluctuations frame by frame, amplified them, and analyzed them...
"This advanced equipment can already successfully analyze whether a suspect is telling the truth or lying, and whether his emotions are fluctuating or stable. Look at this..." Professor Yang pointed to the peaks and valleys of the curve on the display.
"Here, he's lying. Look at his expression. He's looking at the interrogator more intently than before, trying to convince the other party of his sincerity, and he seems stiff when answering questions..." Professor Yang.
"Here, he didn't lie, but he seemed very unconfident... Look, let's enlarge this photo again... Look, one of his shoulders shook a little." Professor Yang.
Sure enough, the trembling of one shoulder was very brief, only one twenty-fifth of a second, but it was captured and recorded by the camera, and then automatically analyzed and marked...
"When he is angry, it is truly angry, not pretended. This is because anger is controlled by the subconscious mind, which is difficult to fake. Moreover, real anger usually appears before or while speaking. Those deliberately pretended anger appear after the words are finished. Under normal circumstances, pretended anger will last longer than real anger, and it is all deliberately shown by the suspect to the investigators..." Professor Yang.
"With this sophisticated instrument, we have a basis for facial recognition. We can more accurately judge whether the suspect's situation is true at the scene. However, as a criminal police officer, we must also learn to recognize common micro-expressions on the face of the human face." Professor Yang.
Then he briefly introduced to Liu Ye and the detectives present a simple method of observing Rao Wei's facial expressions...
For example, when you are happy, the corners of your mouth will turn upwards, your cheeks will also lift up, forming certain wrinkles, and your eyelids will pull down, forming "crow's feet" at the end of your eyes...
For example, when you are sad, your eyebrows will tighten, your eyes will squint, the corners of your mouth will droop, and your chin will be raised or tightened...
And fear, anger, disgust, surprise, contempt—
For example, when a person is afraid, his mouth and eyes will open wide involuntarily, his eyebrows will rise, and his nostrils will unconsciously dilate...
When a person is angry, his eyebrows tend to droop slightly, his forehead may be wrinkled, and the muscles of his eyelids and mouth may be tense...
When a person feels disgusted, his eyebrows will droop slightly, he will unconsciously squint, sneer, and his upper lip will lift up...
When a person is surprised, his eyelids and eyebrows will slightly lift up, his eyes will unconsciously widen, and his lips and surrounding muscles and chin will relax, causing the chin to droop...
When a person is contemptuous, one corner of his mouth may turn upward, sneer, or express sneer or pride...
Just then, Ju Yi, who was sitting in the interrogation room, suddenly answered:
"That bad friend I know, Jiang... Jiang..." Ju Yi, whose expression was calm just now, had a 180-degree reversal on his face. His eyes were scattered, his gaze was dull, the corners of his mouth were tightly closed, and his nostrils were unconsciously widened!
