Malcolm Gladwell laporan pada seni atau itu ilmu pengetahuan? wajah membacaKita semua membaca wajah. Ketika seseorang mengatakan, aku mencintaimu, kami melihat bahwa orang s mata untuk menilai ketulusan nya. Saat kita bertemu seseorang yang baru, kita sering pickup pada sinyal halus, sehingga, meskipun ia mungkin telah berbicara secara normal dan ramah, setelah itu, kita berkata, aku don t pikir dia menyukai saya atau saya don t pikir dia s sangat bahagia. Kita dengan mudah membedakan kompleks perbedaan dalam ekspresi wajah.Wajah adalah instrumen sangat efisien komunikasi bahwa harus ada aturan yang mengatur cara kita menafsirkan ekspresi wajah. Tapi apa aturan-aturan? Dan mereka yang sama untuk semua orang? Pada 1960-an, seorang psikolog muda bernama Paul Ekman mulai belajar ekspresi wajah, dan ia menemukan bahwa tidak ada yang tahu jawaban atas pertanyaan-pertanyaan. Ekman pergi untuk melihat seorang antropolog disebut Margaret Mead dan menyarankan padanya bahwa ia berkeliling dunia untuk mencari tahu apakah orang-orang dari budaya yang berbeda menyepakati arti dari ekspresi wajah yang berbeda. Mead adalah tidak terkesan. Seperti kebanyakan ilmuwan sosial hari-nya, dia percaya bahwa ekspresi budaya bertekad bahwa kita hanya digunakan wajah kita menurut satu set belajar sosial Konvensi.If the face was part of a physiological system, he reasoned, the system could be learned. He set put to teach himself and was introduced to the face reading business by a man named Silvan Tomkins, possibly the best face reader of all time. Ekman�s most memorable encounter with Tomkins took place in the late 1960s. Ekman had just tracked down 30,000 metres of film that had been shot by the virologist Carleton Gajdusek in the remote jungles of Papua New Guinea. Some of the footage was of a tribe called the South Fore, who were peaceful and friendly people. The rest was of the Kukukuku, who were hostile and murderous. Ekman was still working on the problem of whether human facial expressions were universal, and the Gajdusek film was invaluable. For six months, Ekman and his collaborator, Wallace Friesen, sorted through the footage. They cut extraneous scenes, focusing just on close � ups of the faces of the tribesmen, and when the cuts were finished, Ekman called in Tomkins.The two men, prote�ge� and mentor, sat at the back of the room, as faces flickered across the screen. Ekman has told Tomkins nothing about the tribes involved. At the end, Tomkins went up to the screen and pointed to the faces of the South Fore. �These are a sweet gentle people, very indulgent, very peaceful�, he said. Then he pointed to the faces of the Kukukuku. �This other group is violent, and there is lots of evidence to suggest murder�. Even today, a third of a century later, Ekman cannot get over what Tomkins did. Ekman recalls, �He went up to the screen and, while we played the film backward in slow motion, he pointed out the particular bulges and wrinkles in the face that he was using to make his judgement. �That�s when I realised�, Ekman says, �that I had to unpack the face�.Ekman and Friesen decided that they needed o create a taxonomy* of facial expressions, so day after day, they sat across from each other and began to make every conceivable face they could. Soon, though, they realized that their efforts weren�t enough. �I met an anthropologist, Wade Seaford, and told him what I was doing, and he said, �Do you have this muscular movement?� And it wasn�t in Ekman�s system because he had never seen it before. �I had built a system based not on what the face can do, but on what I had seen. I was devastated. I realized that I had to learn the anatomy�.The two then combed trough medical textbooks that outlined each of the facial muscles, and identified every distinct muscular movement that the face could make. There were 43 such movements. Ekman and Friesen called them �action units�. Then they sat across from each other again and began manipulating each action unit in turn, first locating the muscle in their mind and then concentrating on isolating it, watching each other closely as they did, checking their movements in a mirror and videotaping the movements for their records.When each of those action units had been mastered, Ekman and Friesen began working action units in combination. The entire process took seven years. �There are 300 combinations of two muscles�, Ekman says. �If you add in a third muscle, you get over 4000. we took it up to five muscled, which is over 10,000 visible facial configurations�. Most of those 10,000 facial expressions don�t mean anything, of course. They are the kind of nonsense faces that children make. But, by working through each action � unit combination, Ekman and Friesen identified about 3000 that did seem to mean something, until they had catalogued the essential repertoire of human emotion.*a scientific list
