In summary, although the face is the most expressive in terms of non-verbal expression, it is also one of the most easily controlled, so its levels of non-verbal leakage can be relatively low with conscious control of facial expressions. [6] Indicators of facial leakage include facial expressions that last too long, that are too intensive, or ...
Voluntary facial expressions are often socially conditioned and follow a cortical route in the brain. Conversely, involuntary facial expressions are believed to be innate and follow a subcortical route in the brain. Facial recognition can be an emotional experience for the brain and the amygdala is highly involved in the recognition process.
Facial expressions are signals that we make by moving our facial muscles on our face. Facial expressions generally signify an emotional state, and each emotional state or state of mind has a specific facial expression, many of which are universally used around the world. [ 16 ]
Facial expression is an important part of body language and the expression of emotion.It can comprise movement of the eyes, eyebrows, lips, nose and cheeks. At one point, researchers believed that making a genuine smile was nearly impossible to do on command.
The development of FACS tools for different species allows the objective and anatomical study of facial expressions in communicative and emotional contexts. Furthermore, a cross-species analysis of facial expressions can help to answer interesting questions, such as which emotions are uniquely human. [21]
Affect displays are the verbal and non-verbal displays of affect (). [1] These displays can be through facial expressions, gestures and body language, volume and tone of voice, laughing, crying, etc. Affect displays can be altered or faked so one may appear one way, when they feel another (e.g., smiling when sad).
A smile is a facial expression formed primarily by flexing the muscles at the sides of the mouth. Some smiles include a contraction of the muscles at the corner of the eyes, an action known as a Duchenne smile. Among humans, a smile expresses delight, sociability, happiness, joy, or amusement.
This means that facial features (such as the eyes or nose) are not explicitly represented in the brain on their own, rather, the entire face is represented. [ 14 ] According to the configural information hypothesis of face recognition , recognising faces involves two stages that use configural information to form holistic representations of faces.
