Ekman recommends training in groups. This can help make the high volume of information easier to learn. We endorse Erika Rosenberg who teaches a five-day FACS workshop that takes students through the entire manual and prepares them for certification. Currently there are no online or in-person versions of FACS training that have been evaluated or approved by Paul Ekman.

There are also accounts in many other published academic articles. The anatomist Hjorstjo did important groundwork in identifying the units of action based on facial muscle groups on which Ekman and Friesen built in developing FACS as a measurement system. The original version of FACS was published in It was a manual, not an article, available for training as the current manual is.

The original version is out of print, and techniques have been modified since then. The manual is the current version, and it is the only one that should be used for scoring today. Right now, there is no central place where FACS coders advertise and are accessible. Intensity scoring [ edit ]. Other letter modifiers [ edit ].

We cataloged more than AU two-way combinations, and then took on all the combinations of three AUs, and so on, until we stopped at combinations of six AUs.

There were a few cases in which we could not be certain which muscle we were voluntarily contracting, so I had a needle inserted into my face to electrically stimulate one or another muscle. When we were about halfway through cataloging these various facial combinations, I heard that there was a Swedish anatomist who had generated a functional anatomy of facial expression.

I visited professor Hjorstjo in the anatomy department of the university of Lund, and found that he had indeed just published a book based on using the same method we had adopted, voluntarily contracting single muscles in some combinations and photographing the changes. His book, which was in English, used drawings of the face, based on his photographs.

While useful in corroborating our findings to date, it was incomplete and not intended to provide a measurement tool. By the end of four years, we had completed what we intended to be a self-instructional manual, including photographs and filmed examples of each AU and many of the combinations. A volume has been published reprinting some of their published scientific articles using FACS.

To accomplish a complete FACS measurement of one minute of facial behavior which means identifying each action unit, exactly when it began to appear, when it reached its apex, how long the apex was held on the face, when it began to decline, and when it disappeared is very slow, precise work. Rarely does just one AU appear. Usually it takes 50 to 60 minutes to score one minute.

Learning FACS is also a slow process requiring 75 to hours, and then a Final Test, which we provide to determine if you have learned it accurately. Nevertheless, in the dr pauls ekman facs analysis since FACS was published inhundreds of articles by various scientists have been published. It was developed by psychologists Paul Ekman and Wallace V.

Friesen with the intention of objectively measuring facial expressions for behavioral science investigations Ekman, Friesen, ; Ekman, Friesen, Hager, Before the development of FACS, a standard system for facial measurement was nonexistent; this was highly problematic in collecting reliable scientific data within the field. FACS is anatomically based and is comprised of 44 distinct Action Units AUswhich correspond to each motion of the face, along with several sets of head and eye movements and positions.

There are numeric codes for each AU to identify the muscle or muscle groups being contracted or relaxed, which create the changes in appearance that are observed, providing the ability to analyze minuet facial motions. The intensity of each facial action AU is documented on a five-point intensity scale. Events are single facial expressions that can be coded in their entirety, having been deconstructed into an AU based description, which can consist of a combination of Action Units or a single Action Unit.

Each AU is related to specific single or groups of muscles, however since a single muscle may act differently and create an array of changes in appearance, AU codes refers to how the muscle moves to create the specific facial change. FACS measures facial movement through frame-by- frame analysis of a video recorded or photographed facial events.

Through the descriptive power of FACS, each detail of an expression can be thoroughly identified and categorized by a trained FACS coder to reveal the specific AUs that produced the expression. Below are the FACS codes for each universal facial expression. Each number is the code of an Action Unit AUthese numbers represent muscle movements individual muscles and muscle groups.

FACS has been utilized in medical studies to distinguish between genuine and fabricated pain expressions. FACS has also been used to distinguish the facial movements related with intoxication, which could be useful in the real world, such as in law enforcement. FACS has proven to be extremely beneficial in the field of mental health.

It has been used to identify different facial cues that distinguish suicidal depressed people from those who are not suicidal. FACS has also been shown to predict the start or remission of depression, schizophrenia, and other psychopathologies, and it has been used to determine how well someone is coping after a devastating loss. FACS has been used to detect physiological abnormalities such as cardiovascular disorders; facial expression analysis studies have predicted transitory myocardial ischemia in coronary patients.

These outstanding research accomplishments utilizing FACS demonstrate the depth of information that may be uncovered by analyzing the facial expressions and facial movements e. Since FACS was first developed, it has primarily been used in deception detection, security, and research, but in recent years it is being used in the arts.
