114-440: A child's 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.g., tongue protrusion) as early as

152-409: 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 can be an emotional experience for

190-621: A lifetime. The precepts also relate to right speech, action and livelihood aspects of the  Noble Eightfold Path , which is essential in Buddhist practices . There are other levels of precepts, varying amongst traditions. In Theravadin tradition, there are Eight Precepts , Ten Precepts , and the Patimokkha . Eight Precepts are a more rigorous practice for laypeople. Ten Precepts are the training rules for samaneras and samaneris , novice monks and nuns , respectively. The Patimokkha

228-770: A small amount to the inflation, combined, they can produce exaggerated scores. The three main factors are the following: Darwin argued that the expression of emotions has evolved in humans from animal ancestors, who would have used similar methods of expression. Darwin believed that expressions were unlearned and innate in human nature and were therefore evolutionarily significant for survival. He compiled supporting evidence from his research on different cultures, on infants, and in other animal species. Ekman found that people from different cultures recognized certain facial expressions despite vast cultural differences, and his findings tended to confirm Darwin's initial hypothesis. Cross-cultural studies had shown that there are similarities in

266-621: A specific person or persons to do or omit something, especially in order to urge the observance of law. In Catholicism , the " Commandments of the Church " may also be called "Precepts of the Church". In Buddhism , the fundamental code of ethics is known as the Five Precepts ( Pañcaśīla in Sanskrit , or Pañcasīla in Pāli ), practiced by laypeople , either for a given period of time or for

304-458: A variety of purposes. It regulates conversations, shows interest or involvement, and establishes a connection with others. But different cultures have different rules for eye contact . Certain Asian cultures can perceive direct eye contact as a way to signal competitiveness, which in many situations may prove to be inappropriate. Others lower their eyes to signal respect, and similarly, eye contact

342-518: 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. More than anything though, what shapes

380-489: Is avoided in Nigeria; however, in western cultures this could be misinterpreted as lacking self-confidence . Even beyond the idea of eye contact, eyes communicate more data than a person even consciously expresses. Pupil dilation is a significant cue to a level of excitement, pleasure, or attraction. Dilated pupils indicate greater affection or attraction, while constricted pupils send a colder signal. Facial expression

418-591: 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

456-401: Is the assumption that certain facial expressions and face-related acts or events are signals of specific emotions (happiness with laughter and smiling, sadness with tears, anger with a clenched jaw, fear with a grimace, or gurn , surprise with raised eyebrows and wide eyes along with a slight retraction of the ears, and disgust with a wrinkled nose and squinted eyes—emotions which frequently lack

494-465: Is the basic Theravada code of monastic discipline, consisting of 227 rules for monks, ( bhikkhus ) and 311 rules for nuns ( bhikkhunis ). In secular law , a precept is a command in writing; a species of writ issued from a court or other legal authority. It is now chiefly used of an order demanding payment (in the UK, for example, the term is applied by local precepting authorities as part of

532-460: Is used in sign languages to convey specific meanings. In American Sign Language (ASL), for instance, raised eyebrows combined with a slightly forward head tilt to indicate that what is being signed is a yes–no question . Lowered eyebrows are used for wh-word questions. Facial expression is also used in sign languages to show adverbs and adjectives such as distance or size: an open mouth, squinted eyes and tilted back head indicate something far while

570-539: The Council Tax system). The Latin form praecipe (i.e., to enjoin, command) is used of the note of instructions delivered by a plaintiff or his lawyer to be filed by the officer of the court, giving the names of the plaintiff and defendant . Princeton University uses the term precept to describe what many other universities refer to as recitations : large classes are often divided into several smaller discussion sections called precepts, which are led by

608-525: The Latin : præcipere , to teach) is a commandment , instruction, or order intended as an authoritative rule of action. In religion , precepts are usually commands respecting moral conduct. The term is encountered frequently in the Jewish and Christian Scriptures : Thou hast commanded thy precepts to be kept diligently. O that my ways may be steadfast in keeping thy statutes! The usage of precepts in

646-741: The Revised Standard Version of the Bible corresponds with that of the Hebrew Bible . The Septuagint (Samuel Rengster edition) has Greek entolas , which, too, may be rendered with precepts. The Latin Church of the Catholic Church 's canon law , which is based on Roman Law , makes a distinction between precept and law in Canon ;49: A singular precept is a decree which directly and legitimately enjoins

684-458: 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. The lower portions of the face are controlled by the opposite cerebral hemisphere , causing asymmetric facial expression. Because the right hemisphere is more specialised for emotional expression , emotions are more strongly expressed on

722-513: The brain and the amygdala is highly involved in the recognition process. 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. There is controversy surrounding the question of whether facial expressions are a worldwide and universal display among humans. Facial expressions are vital to social communication between humans. They are caused by

760-640: The chimps in evaluating their expressions. Of course, differences between the species' physical facial properties, such as white sclera and everted lips in chimps, would mean that some expressions could not be compared. Similarly, Darwin observed that infants' method of expression for certain emotions was instinctive, as they were able to display emotional expressions they had not themselves yet witnessed. Facial morphology impacts expression recognition in important ways, and therefore, infant facial morphology may also serve some specific communicative function. These similarities in morphology and movement are important for

798-488: The correct interpretation of an emotion. Darwin was particularly interested in the functions of facial expression as evolutionarily important for survival. He looked at the functions of facial expression in terms of the utility of expression in the life of the animal and in terms of specific expressions within species. Darwin deduced that some animals communicated feelings of different emotional states with specific facial expressions. He further concluded that this communication

836-540: The first few days of life. 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. A 2020 study on "emotion residue" found that even when study participants attempted to make neutral facial expressions, their faces still retained emotion residue from prior expressions, and these prior expressions were able to be detected by observers. A 1988 study on

874-475: The first pharyngeal arch. There 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

912-432: The formation of impressions. This article discusses eyes and facial expressions and the effect they have on interpersonal communication . A person's 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

950-470: The left side of the face, particularly for negative emotions . Asymmetries in expression can be seen in chimeric faces (facial portraits made by combining the left and right halves of faces with different expressions) and also in portraits which more often show the left, more emotional side of the face than the right. The amygdala plays an important role in facial recognition. Functional imaging studies have found that when shown pictures of faces, there

1026-458: The looking behaviors of others convey 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

1064-438: The matching facial expression from an array of three faces. The Fore selected the correct face on 64–90% of trials but had difficulty distinguishing the fear face from the surprise face. Children selected from an array of only two faces, and their results were similar to the adults'. Subsequent cross-cultural studies found similar results Both sides of this debate agree that the face expresses emotion. The controversy surrounds

1102-645: The mouth pulled to one side and the cheek held toward the shoulder indicate something close, and puffed cheeks mean very large. It can also show the manner in which something is done, such as carelessly or routinely. Some of these expressions, also called non-manual signs, are used similarly in different sign languages while others are different from one language to another. For example, the expression used for 'carelessly' in ASL means 'boring or unpleasant' in British Sign Language . The universality hypothesis

1140-460: 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

1178-522: 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 1980. Though Tecce's data is interesting, it is important to recognize that non-verbal communication is multi-channeled, and focusing on only one aspect is reckless. Nervousness can also be measured by examining each candidates' perspiration, eye contact and stiffness. Within their first year, Infants learn rapidly that

1216-650: The social component of those like shame, pride, jealousy, envy, deference, etc.) and are recognized by people regardless of culture, language, or time. The belief in the evolutionary basis of these kinds of facial expressions can be traced back to Darwin 's The Expression of the Emotions in Man and Animals . Reviews of the universality hypothesis have been both supportive and critical. Work in 2013 by Nelson and Russell and Jack et al. has been especially critical. Ekman 's work on facial expressions had its starting point in

1254-487: The uncertainty about what specific emotional information is read from a facial expression. Opponents of the universality hypothesis believe that more general information is pieced together with other contextual information in order to determine how a person feels. One argument against the evidence presented in support of the universality hypothesis is that the method typically used to demonstrate universality inflates recognition scores. Although each factor may contribute only

1292-421: The way emotions are expressed across diverse cultures, but studies have even shown that there are similarities between species in how emotions are expressed. Research has shown that chimpanzees are able to communicate many of the same facial expressions as humans through the complex movements of the facial muscles. In fact, the facial cues were so similar that Ekman's Facial Action Coding System could be applied to

1330-621: The work of psychologist Silvan Tomkins . Ekman showed that facial expressions of emotion are not culturally determined, but universal across human cultures. To demonstrate his universality hypothesis, Ekman ran a test on a group of the South Fore people of New Guinea , a pre-industrial culture that was isolated from the West. The experiment participants were told brief stories about emotional events (happiness, sadness, anger, fear, surprise, and disgust). After each story, they were asked to select

1368-505: The “facial feedback” hypothesis found that study participants mood was improved when they smiled. However, this study later failed a large replication attempt. One experiment investigated the influence of gaze direction and facial expression on face memory. Participants were shown a set of unfamiliar faces with either happy or angry facial expressions, which were either gazing straight ahead or had their gaze averted to one side. Memory for faces that were initially shown with angry expressions

1406-405: Was found to be poorer when these faces had averted as opposed to direct gaze, whereas memory for individuals shown with happy faces was unaffected by gaze direction. It is suggested that memory for another individual's face partly depends on an evaluation of the behavioural intention of that individual. A person's face, especially their eyes, creates the most obvious and immediate cues that lead to

1444-459: Was important for the survival of animals in group-dwelling species; the skill to effectively communicate or interpret another animal's feelings and behaviors would be a principal trait in naturally fit species. However, this suggests that solitary species such as orangutans would not exhibit such expressions. For a discussion of the controversies on these claims, see Fridlund and Russell & Fernandez Dols.
