A '''gesture''' is a form of [[non-verbal communication]] made with a part of the body, used instead of or in combination with ''verbal communication''. The language of gesture allows individuals to express a variety of feelings and thoughts, from contempt and hostility to approval and affection. Most people use gestures and [[body language]] in addition to [[word]]s when they speak. The use of gesture as language by some ethnic groups is more common than in others, and the amount of such gesturing that is considered culturally acceptable varies from one location to the next.
==Types of gestures==
[[Image:Unclesamwantyou.jpg|right|thumb|250px|[[Type of gesture#Pointing|Pointing]] with an extended finger is offensive in many cultures.]] Gestures do not have invariable or universal meanings. Even simple gestures like pointing at someone can give offense if it is not done correctly. In the USA and western European countries it is very common for people to point with an extended finger but in Asia this is considered very rude (see [[Etiquette in Asia]] for details) and it is safer to use the whole hand.
Different types of gestures are distinguished. Well-known type of gestures are the so-called emblems or quotable gestures (see the examples below). These are culture-specific gestures that can be used as replacement for words. Communities have repertoires of such gestures. A single emblematic gesture can a have very different significance in different cultural contexts, ranging from complimentary to highly offensive <ref>Morris, Desmond, Collett, Peter, Marsh, Peter, O'Shaughnessy, Marie. 1979. Gestures, their origins and distribution. London. Cape</ref>
Another type of gestures are the ones we use when we speak. These gestures are closely coordinated with speech. The meaningful part of the gesture is temporally synchronized (that is, occurs at the same time) with the co-expressive parts of speech. For example, a gesture that depicts the act of throwing will be synchronous with the word 'threw' in the utterance "and then he threw the ball right into the window." Other gestures, like the so-called beat gestures, are used in conjunction with speech and keep time with the rhythm of speech to emphasize certain words or phrases. These types of gestures are integrally connected to [[Speech communication|speech]] and thought processes. <ref>McNeill (1992). Hand and Mind. Chicago: University of Chicago Press</ref>
==Studies of gesture==
Gestures have been studied throughout the centuries from different view points. <ref>Kendon, A. (1982). The study of gesture: Some observations on its history. Recherches Sémiotiques/Semiotic Inquiry 2 (1)</ref> Quintillian in the antiquity studied in his Institution Oratoria how gesture may be used in rhetorical discourse. The another broad study of gesture was published by [[John Bulwer]] in 1644.<ref>Bulwer, John (1644). "Chirologia: or the Naturall Language of the Hand" (London,1644)</ref> Bulwer analyzed dozens of gestures and provided a guide on how to use gestures to increase eloquence and clarity for public speaking. Today, one of the most prominent researchers in the field of gesture research is [[Adam Kendon]]. He has investigated many aspects of gestures, including their role in communication, conventionalization of gesture, integration of gesture and speech, and the evolution of language <ref>Kendon (2004). Gesture: Visible Action as Utterance. Cambridge: Cambridge University Press</ref>. Other prominent researchers in this field include [[Susan Goldin-Meadow]] and [[David McNeill]]. Susan Goldin-Meadow (2003) has investigated intensively the role of gesture in problem solving in children<ref>Goldin-Meadow, Susan (2003). Hearing gesture: How our hands help us think. Cambridge, MA: Harvard University Press</ref>. David McNeill (1992, 2006)<ref># McNeill, David (1992). Hand and Mind. What Gestures Reveal about Thought. Chicago: Chicago University Press.
McNeill, David (2005). Gesture and Thought. Chicago: Chicago University Press</ref> has developed a broad theory about how gesture and speech are part of a single thought process.
==Social significance==
[[Image:VitarkaMudra.JPG|thumb|right|200px|Vitarka [[mudra]], [[Tarim Basin]], 9th century.]]
Gestures play a major role in many aspects of human life. Gesturing is probably a universal, there has been no report of a community that does not gesture. Gestures are a crucial part of everyday conversation such as chatting, describing a route, negotiating prices on a market; they are ubiquitous. Gestures have been documented in the arts such as in Greek vase paintings, Indian Miniatures or European paintings.
Gestures play a central role in religious or spiritual rituals such as the [[Christianity|Christian]] [[sign of the cross]]. In [[Hinduism]] and [[Buddhism]], a ''[[mudra]]'' ([[Sanskrit]], literally "seal") is a symbolic gesture made with the hand or fingers. Each mudra has a specific meaning, playing a central role in Hindu and Buddhist [[iconography]]. An example is the Vitarka mudra, the gesture of discussion and transmission of Buddhist teaching. It is done by joining the tips of the thumb and the index together, while keeping the other fingers straight.
==Hand gestures==
{{main|Hand gesture}}
'''Hand gestures''', i.e., gestures performed by one or two [[hand]]s, is the most numerous category of gestures due to the ability of the human hand to acquire a huge number of clearly discernible configurations, the fact of importance for the [[sign language]]s. The latter ones are not discussed in this article.
==Body gestures==
This is moving the body in a certain way when orally communicating.
===Mooning===
[[Mooning]] is the act of displaying one's [[nudity|bare]] [[buttocks]] by lowering the back side of one's [[trousers]] and [[underpants]], usually without exposing the [[genitals]]. Mooning is used in some cultures to express protest, scorn, disrespect, or provocation. It can also be done for [[shock value]]
===Anasyrma===
[[Anasyrma]] or "lifting the skirts" is a gesture traceable to European antiquity. It is used in connection with certain religious rituals, eroticism, and lewd jokes.
===The "peacock"===
Expresses superiority or domination combined with a certain degree of smug arrogance. Performed by pushing the chest up and out at the front as well as tilting the face slightly upward. This may be accompanied by motions of hooking both thumbs under one's [[lapel]]s or [[suspenders]] even if they are not present.
==Head/face gestures==
===Facial expressions===
{{main|Facial expression}}
Facial expressions are a rich language in their own right and will not be discussed in this article. Some facial expressions are byproducts of emotions, while others, such as [[wink]]ing or eye-rolling are akin to gestures.
===Eye-rolling===<!-- This section is linked from [[Rolling eyes]] -->
Rotating the eyes upward may have the following meanings.
*It may indicate condescension, contempt, boredom, or exasperation. The gesture is often for a rescue from boredom or frustration. It can be interpreted as the equivalent of saying, "I don't like this" or "I think this is really stupid" or "I simply can't believe this."<ref>{{cite web

===Nodding===
A [[nod (gesture)|nod]] is a gesture of confirmation in many cultures and negation in some (e.g., in [[Bulgaria]] and [[Sri Lanka]]).
===Head bobble===
Head bobble, i.e., repeated alternating tilting of the head to the left and to the right in arcs along the [[coronal plane]], means disapproval in some cultures, e.g., in the [[East Slavic]] culture. {{Fact|date=April 2008}} This same head movement in India means "OK". {{Fact|date=April 2008}}
===Head shaking===
Repeated turning of the head side to side in arcs along the [[transverse plane]] has a meaning opposite to the nod: negation in many cultures and confirmation in some.
===Bent head===
A gesture of shame, subduing, or agreement/confirmation. An interpretation depends on the way it being performed and overall body context. Or, can be used as a greeting.
===Pointing by chin===
A direction may be pointed by chin, e.g., when the arms are doing something else: the head is turned in the corresponding direction and the chin is slightly jerked up and in the pointed direction. This is also used as a greeting in some regions in the U.S., usually among young men.
===Greeting by nod===
A single nod of the head, (one single cycle in image-pitch) characterizes a greeting gesture.<ref>[http://www.umiacs.umd.edu/~yaser/head.ps.gz Recognition of Head Gestures Using Hidden Markov Models.]</ref>
