Nonverbal communication in the context of "Oculesics"

A gesture is a form of nonverbal communication or non-vocal communication in which visible bodily actions communicate particular messages, either in place of, or in conjunction with, speech. Gestures include movement of the hands, face, or other parts of the body. Gestures differ from physical non-verbal communication that does not communicate specific messages, such as purely expressive displays, proxemics, or displays of joint attention. Gestures allow individuals to communicate a variety of feelings and thoughts, from contempt and hostility to approval and affection, often together with body language in addition to words when they speak. Gesticulation and speech work independently of each other, but join to provide emphasis and meaning.

Gesture processing takes place in areas of the brain such as Broca's and Wernicke's areas, which are used by speech and sign language. In fact, language is thought by some scholars to have evolved in Homo sapiens from an earlier system consisting of manual gestures. The theory that language evolved from manual gestures, termed Gestural Theory, dates back to the work of 18th-century philosopher and priest Abbé de Condillac, and has been revived by contemporary anthropologist Gordon W. Hewes, in 1973, as part of a discussion on the origin of language.

Body language is a type of nonverbal communication in which physical behaviors, as opposed to words, are used to express or convey information. Such behavior includes facial expressions, body posture, gestures, eye movement, touch and the use of space. Although body language is an important part of communication, most of it happens without conscious awareness. In social communication, body language often complements verbal communication. Nonverbal communication has a significant impact on doctor-patient relationships, as it affects how open patients are with their doctor.

As an unstructured, ungrammatical, and broadly-interpreted form of communication, body language is not a form of language. It differs from sign languages, which are true languages with complex grammar systems and exhibiting the fundamental properties considered to exist in all languages.

Interpersonal communication is an exchange of information between two or more people. It is also an area of research that seeks to understand how humans use verbal and nonverbal cues to accomplish several personal and relational goals. Communication includes utilizing communication skills within one's surroundings, including physical and psychological spaces. It is essential to see the visual/nonverbal and verbal cues regarding the physical spaces. In the psychological spaces, self-awareness and awareness of the emotions, cultures, and things that are not seen are also significant when communicating.

Interpersonal communication research addresses at least six categories of inquiry: 1) how humans adjust and adapt their verbal communication and nonverbal communication during face-to-face communication; 2) how messages are produced; 3) how uncertainty influences behavior and information-management strategies; 4) deceptive communication; 5) relational dialectics; and 6) social interactions that are mediated by technology.

In linguistics and the philosophy of language, pragmatics is the study of how context contributes to meaning. The field of study evaluates how human language is utilized in social interactions, as well as the relationship between the interpreter and the interpreted. Linguists who specialize in pragmatics are called pragmaticians. The field has been represented since 1986 by the International Pragmatics Association (IPrA).

Pragmatics encompasses phenomena including implicature, speech acts, relevance and conversation, as well as nonverbal communication. Theories of pragmatics go hand-in-hand with theories of semantics, which studies aspects of meaning, and syntax, which examines sentence structures, principles, and relationships. Pragmatics, together with semantics and syntactics, is a part of semiotics. The ability to understand another speaker's intended meaning is called pragmatic competence. In 1938, Charles Morris first distinguished pragmatics as an independent subfield within semiotics, alongside syntax and semantics. Pragmatics emerged as its own subfield in the 1950s after the pioneering work of J. L. Austin and Paul Grice.

Facial expression is the motion and positioning of the muscles beneath the skin of the face. These movements convey the emotional state of an individual to observers and 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.

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 can be an emotional experience for the brain and the amygdala is highly involved in the recognition process.

Waving is a nonverbal communication gesture that consists of the movement of the hand and/or entire arm that people commonly use to greet each other, but it can also be used to say goodbye, acknowledge another's presence, call for silence, or deny someone. The wave gesture is an essential element of human language.

An emotional expression is a behavior that communicates an emotional state or attitude. It can be verbal or nonverbal, and can occur with or without self-awareness. Emotional expressions include facial movements like smiling or scowling, simple behaviors like crying, laughing, or saying "thank you," and more complex behaviors like writing a letter or giving a gift. Individuals have some conscious control of their emotional expressions; however, they need not have conscious awareness of their emotional or affective state in order to express emotion.

Researchers in psychology have proposed many different and often competing theoretical models to explain emotions and emotional expression, going as far back as Charles Darwin's discussion of emotion as an evolved capacity. Though there is no universally accepted theory of emotion, theorists in emotion agree that experience of emotions and expression of them in a variety of ways, such as with voices, faces, and bodies, is key to human communication. The cultural norms and beliefs of a society also affect and shape the emotional expressions of its members, and expressions appropriate and important in one culture may be taboo in another.

Proxemics is the study of human use of space and the effects that population density has on behavior, communication, and social interaction. Proxemics is one among several subcategories in the study of nonverbal communication, including haptics (touch), kinesics (body movement), vocalics (paralanguage), and chronemics (structure of time).

Edward T. Hall, the cultural anthropologist who coined the term in 1963, defined proxemics as "the interrelated observations and theories of humans' use of space as a specialized elaboration of culture". In his foundational work on proxemics, The Hidden Dimension, Hall emphasized the impact of proxemic behavior (the use of space) on interpersonal communication. According to Hall, the study of proxemics is valuable in evaluating not only the way people interact with others in daily life, but also "the organization of space in [their] houses and buildings, and ultimately the layout of [their] towns". Proxemics remains a hidden component of interpersonal communication that is uncovered through observation and strongly influenced by culture.

Eye contact occurs when two people or non-human animals look at each other's eyes at the same time. In people, eye contact is a form of nonverbal communication and can have a large influence on social behavior. Coined in the early to mid-1960s, the term came from the West to often define the act as a meaningful and important sign of confidence and respect. The customs, meaning, and significance of eye contact can vary greatly between societies, neurotypes, and religions.

The study of eye contact is sometimes known as oculesics.
