Paul Ekman born February 15, 1934 is an American psychologist and professor emeritus at the University of California, San Francisco who is a pioneer in the study of. Facial expression Wikipedia. Photographs from the 1. Mcanisme de la Physionomie Humaine by Guillaume Duchenne. Through electric stimulation, he determined which muscles were responsible for different facial expressions.

A facial expression is one or more motions or positions of the muscles beneath the skin of the face. According to one set of controversialcitation needed theories, these movements convey the emotional state of an individual to observers. Facial expressions are a form of nonverbal communication.

They are a primary means of conveying social information between humans, but they also occur in most other mammals and some other animal species. For a discussion of the controversies on these claims, see Fridlund1 and Russell Fernandez Dols. The pioneer F M Facial Action Coding System 2. F M FACS 2. 0 3 was created in 2. Dr. Freitas Magalhes, and presents about 2,0. K, using 3. D technology and automatic and real time recognition. Humans can adopt a facial expression voluntarily or involuntarily, and the neural mechanisms responsible for controlling the expression differ in each case. 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 is often an emotional experience for the brain and the amygdala is highly involved in the recognition process. The eyes are often viewed as important features of facial expressions. Aspects such as blinking rate can be used to indicate whether a person is nervous or whether he or she is lying. Also, eye contact is considered an important aspect of interpersonal communication. However, there are cultural differences regarding the social propriety of maintaining eye contact or not. Beyond the accessory nature of facial expressions in spoken communication between people, they play a significant role in communication with sign language. Many phrases in sign language include facial expressions in the display. There is controversy surrounding the question of whether facial expressions are worldwide and universal displays among humans. Supporters of the Universality Hypothesis claim that many facial expressions are innate and have roots in evolutionary ancestors. The widespread use of facial recognition technology is almost upon us. A new iPhone is on the horizon, and it might not even have a fingerprint readerinstead, you.

Facial Action Coding System Manual' title='Facial Action Coding System Manual' />Opponents of this view question the accuracy of the studies used to test this claim and instead believe that facial expressions are conditioned and that people view and understand facial expressions in large part from the social situations around them. CreationeditFacial muscleseditFacial expressions are vital to social communication between humans. They are caused by the movement of muscles that connect to the skin and fascia in the face. These muscles move the skin, creating lines and folds and causing the movement of facial features, such as the mouth and eyebrows. These muscles develop from the second pharyngeal arch in the embryo. The temporalis, masseter, and internal and external pterygoid muscles, which are mainly used for chewing, have a minor effect on expression as well. These muscles develop from the first pharyngeal arch. Neuronal pathwayseditThere are two brain pathways associated with facial expression the first is voluntary expression. Voluntary expression travels from the primary motor cortex through the pyramidal tract, specifically the corticobulbar projections. The cortex is associated with display rules in emotion, which are social precepts that influence and modify expressions. Cortically related expressions are made consciously. The second type of expression is emotional. These expressions originate from the extrapyramidal motor system, which involves subcortical nuclei. For this reason, genuine emotions are not associated with the cortex and are often displayed unconsciously. This is demonstrated in infants before the age of two they display distress, disgust, interest, anger, contempt, surprise, and fear. Infants displays of these emotions indicate that they are not cortically related. Similarly, blind children also display emotions, proving that they are subconscious rather than learned. Other subcortical facial expressions include the knit brow during concentration, raised eyebrows when listening attentively, and short punctuation expressions to add emphasis during speech. People can be unaware that they are producing these expressions. Neural mechanisms in face perceptioneditThe amygdala plays an important role in facial recognition. Functional imaging studies have found that when shown pictures of faces, there is a large increase in the activity of the amygdala. The amygdala receives visual information from the thalamus via the subcortical pathways. The amygdala may also have a significant role in the recognition of fear and negative emotions. It is believed that the emotion disgust is recognized through activation of the insula and basal ganglia. The recognition of emotion may also utilize the occipitotemporal neocortex, orbitofrontal cortex and right frontoparietal cortices. Gender and facial cueseditMore than anything though, what shapes a childs cognitive ability to detect facial expression is being exposed to it from the time of birth. The more an infant is exposed to different faces and expressions, the more able they are to recognize these emotions and then mimic them for themselves. Infants are exposed to an array of emotional expressions from birth, and evidence indicates that they imitate some facial expressions and gestures e. In addition, gender affects the tendency to express, perceive, remember, and forget specific emotions. For instance, angry male faces and happy female faces are more recognizable, compared to happy male faces and angry female faces. CommunicationeditEye contacteditA persons face, especially their eyes, creates the most obvious and immediate cues that lead to the formation of impressions. This article discusses eyes and facial expressions and the effect they have on interpersonal communication. A persons eyes reveal much about how they are feeling, or what they are thinking. Blink rate can reveal how nervous or at ease a person may be. Research by Boston College professor Joe Tecce suggests that stress levels are revealed by blink rates. He supports his data with statistics on the relation between the blink rates of presidential candidates and their success in their races. Tecce claims that the faster blinker in the presidential debates has lost every election since 1. Though Tecces data is interesting, it is important to recognize that non verbal communication is multi channeled, and focusing on only one aspect is reckless. Capcom Vs Mortal Kombat For Pc. Nervousness can also be measured by examining each candidates perspiration, eye contact and stiffness. Within their first year, Infants learn rapidly that the looking behaviors of others conveys significant information. Infants prefer to look at faces that engage them in mutual gaze and that, from an early age, healthy babies show enhanced neural processing of direct gaze. Eye contact is another major aspect of facial communication. Some have hypothesized that this is due to infancy, as humans are one of the few mammals who maintain regular eye contact with their mother while nursing. Eye contact serves a variety of purposes.
