When judging whether the face of a man is "sexually attractive" or not,Women are parts of men's lips and chinAlthough it seems that it seems to judge by looking at, in the beginning, the human brain automatically decides the impression of the other person even by showing the human face picture in the moment earlier than the speed which the brain can recognize, this impression The results of the New York University clarified that the impression is the same as the impression of looking at the person's face carefully.

Face Value: How Our Brain Decides Who We Can Trust - Everyday Health

About the impression formed when looking at the human face so farthe studyMany have been done. Through these previous studies, it is known that the human brain automatically decides the opponent's first impression when looking at a stranger's face, for example, if a cheekbone is present, it is easy for the opponent to trust, and a big eye People are considered to be attractive to their opponents. But why the human brain felt that way was almost unknown.

In the research, we prepared a real face and a computer generated face set, asked the subject to see a certain number of sets of faces, firstly investigated whether they had the impression that the previous research shows. This experimental result seems to have been almost the same as the result of the previous study, and it has also been found that human beings tend to strongly believe the judgment on reliability received from the impression of the face.

After that, I showed the same image to another group of subjects for 33 milliseconds, which was shorter than the time required to consciously grasp what happened to the brain. This "33 milliseconds" is a short enough time to recognize what happened to the brain, but it is enough time for the tonsils of the brain to respond. In this moment the brain seems to have brought the impression of the opponent from the facial photograph, and the result of that impression seems to have obtained the same result as when looking at the photograph of the face carefully.

The pictures actually used in the experiment are as follows. The top is a real photo, the bottom is a computer generated face photo. In these pictures, the inside of the eyebrows are on the left side and the inside goes up as you go to the right. In addition, there are few cheeks on the left side, and the cheek bone comes out as you go to the right.

The experimental result was that the face of the photograph on the right was judged to be a "more reliable" face, even if it could only see the picture for a moment of 33 milliseconds.

Experimental Results Jonathan Freeman, assistant professor at psychology department at New York University, said, "Our findings are that the brain automatically determines the human face as trustworthy earlier than recognizing the face with the head The impression of the opponent formed in the experiment of various previous research results and the experiment which we showed face only for a moment outside human perception is perfectly consistent "Is called. Furthermore, Mr. Freeman said that "the face with the inside of the eyebrows high and the cheek bones clear" is a reliable face, "face with the inside of the eyebrows low, the face where the cheeks do not appear" is unreliable face and It is said that more solid evidence of the theory that it can be seen is obtained.

In addition, according to other studies at New York University announced last month, it is known that parts other than the eyebrows and cheeks give a different impression to the brain in the same way, for example, a full smile is "friendly" ( Approachability) ", the impression such as" Youthful-Attractiveness "is influenced by the shape and size of the eyes, and the structure of the masculine face is impressed as" Dominance "in the brain I know that.

Since it is also known that there is no correlation between these features and the actual personality, it seems that it is a prohibition to not doubt the opponent at all though it is a face that can be trusted.
