More and more computers demonstrate their superiority over people in solving a variety of tasks, according to the Internet edition for girls and women from 14 to 35 years old Pannochka. net New research revealed that a computer system is better able to recognize a person when people simulate pain.

Researchers from the University of California at San Diego (UCSD) and the University of Toronto in Canada published the results of testing their offspring in the journal Current Biology.

They note that in social species, such as a person, a person is able to display valuable information in the public context, and this refers to the expression of pain.

"Nevertheless, people can imitate facial expressions and pretend to be so good that most observers will not understand them," says Professor Kang Lee, lead author of the study, a researcher at the University of Toronto.

According to the authors of the study, there are two motor ways in the brain that control our facial expressions:.

• Subcortical extrapyramidal motor system that controls spontaneous facial expressions that display real emotions.

• Cortical pyramidal system, which is responsible for arbitrary (simulated) movements of the muscles of the face.

While people are unable to pinpoint the smallest differences between the two systems, the computer can do this with high accuracy.

"The computer system is designed by us to distinguish the subtle dynamic characteristics of the facial expression that the human eye misses. A person simply does not look carefully enough at those characteristics that distinguish the real expression of pain from pretense, "says Marian Bartlett, lead author of the study from the University of California.

In their experiment it was shown that a person can distinguish real pain from pretense only by accident, that is 50 to 50. Even after a special training, a person can improve his performance to about 55%.

But scientists say that their computer was able in most cases to accurately determine the difference between the movements of the face, controlled pyramidal (false) and extrapyramidal (true) structures.

A system that automatically measures the movement of different parts of the face and compares them to programmed patterns, was able to distinguish real and false emotions in 85% of cases.

The researchers suggest that the only most predictable aspect is the movement of the mouth. When people pretend pain, their mouth opens slightly too often and with less variability of movements.

Professor Li says: "Thanks to the structure of our brain, people can simulate emotions sufficiently to deceive only other representatives of their species.

The computer much better fixes the subtle differences between arbitrary and involuntary movements of the face ".

Professor Bartlett says that with the help of computer systems you can collect "behavioral fingerprints" that will allow you to recognize the emotions of people, and use this knowledge in a variety of areas.

Scientists believe that their invention has great prospects in the field of national security, psychopathology, recruiting personnel, health and law enforcement.
