I. The notion of Facial Action Coding Units
• A facial action, as defined by Ekman et al. 2002, can be
described as the action of one or several muscles situated in a
part of the face.
• There is an action when there is a visible movement.
• Each action has:
• - A number ( 4 for frowning, 12 for smiling, etc.).
• - An intensity ( A for very weak, D for extreme intensity). 4D is extreme
frowning.
• - Symmetry (S for symmetry, R for only right side and L for only left side).
R4D means extreme frowning with the right eyebrow.
• What I call a chronic position is not coded in the FACS system.
For example a person may have eye brows which are
permanently pulled down and close to each other, as in
frowning.

Table 1-1: Single Action Units (AU)
The table indicates where we have collapsed more than one muscle into a single Action Unit, or where we
have distinguished more than one Action Unit from a single muscle. The FACS names given in the table
are a shorthand, not meant to describe the appearance changes, but a convenience to call them to mind.

Note how AU05 is important for anger, fear & surprise.
Sadness
• Introductory remarks:
•
•
•
- Although weeping and tears are a common concomitant of sad expressions, tears
are not indicative of any particular emotion, as in tears of joy (Darwin 1872,
Chapter VI). Infants do not shed tears during the first two or three months, when
they are sad. This correlates with Rochat’s (2001) observation that during the first
6 weeks children do not seem to communicate with others, although their
behavior may be experienced as expressive.
- Intensity of sad expressions does not always correlate with intensity of sadness
(Kostić 2003).
Darwin (1872, Chapter VI) notes that there are two types of grief:
an expressive phase, and a deeper one which generates a lack of
expression
•
•
•
•
•
•
•
•
•
•
•
•
A) Expressive phase (the one studied by Ekman)
- Children have prolonged expirations with short and rapid, almost spasmodic
inspirations (the breath is inhaled almost spasmodically), followed at somewhat more
advances age by sobbing. The manipulation of this dimension can make one cry.
- Screams with closed eyes and wrinkles around them, with compression of the eye balls.
- Opened mouth with retracted lips so that the mouth opening is square.
- AU01 is often present.
- AU17 + AU 11 (raised chin with deepening of the naso-labial fold)
A) Despair or deep sorrow (for Ekman this is more depression than sadness): silent
motionless grief
- Sitting motionless, with a gentle rock to and fro.
- Skin pales.
- Respiration is almost forgotten, but deep sighs are drawn.
- Prostration: collapsed muscles and dulled eyes.
Suzanna Block and the globality of expression
•
•
•
•
•
The Darwinian stance on expression is that it mobilizes all the dimensions of the
organism, a fact which is particularly visible on an infant who expresses himself
using the body from head to feet as one expressive system.
An example of research from this perspective is that of Susanna Bloch (1989). She
tried to study which bodily activation could help actors to activate an emotion in
their organism. For example postures with tense muscles activated fear and anger,
while sadness, tenderness and joy could mostly be situated by relaxed postures.
In the case of sadness, effective postures were usually closed postures, with
protection of the ventral surface and a curved spine, as well as limp or even
hypotonic muscle tone in certain areas.
Her work mostly focused on what breathing pattern induced a basic emotion. The
crucial elicitor for sadness is Darwin’s spasmodic inspiration.
Most efficient was the combination of facial, respiratory and postural emotional
traits.

Suicide study (Heller et al. 2001)
•
•
•
•
- 23 patients were filmed less than 48 hours after a suicide attempt. 11 made a
suicide attempt during a follow up period of 900 days, 12 made no further suicide
attempt in this period, to our knowledge.
This is list of the expressions observed during short filmed samples. The time is in
1/100 of a second unit (maximum is 4340, which is 43.40 seconds).
- In such circumstances sadness is expected. Except for a few examples, expressed
sadness is observed, but in this sample as well as in others we viewed, not
prevalent. As sadness was “in the air” most of the time, blended with other
emotional expressions (contempt, anger, fear, etc.), one would need to redefine
Darwin’s second type of despair, which has few facial components.
- Sadness does not alone one to distinguish patients who made other suicide
attempts from those that did not. The signs that correlated with suicide attempt
risk were not emotional expressions, as defined by Ekman (2007).
