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.

As an unstructured, ungrammatical, and broadly-interpreted form of communication, body language is not a form of language.[1] It differs from sign language, which are true languages with complex grammar systems and exhibiting the fundamental properties considered to exist in all languages.[2][3]

Some researchers conclude that nonverbal communication accounts for the majority of information transmitted during interpersonal interactions.[4] It helps to establish the relationship between two people and regulates interaction, yet it can be ambiguous. The interpretation of body language tends to vary in different cultural contexts. Within a society, consensus exists regarding the accepted understandings and interpretations of specific behaviors. However, controversy exists on whether body language is universal. The study of body language is also known as kinesics.

Physical expressions

[edit]

Facial expressions

[edit]

Facial expression is a 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. More recently, however, a study conducted by researchers at Northeastern University found that people could convincingly fake a Duchenne smile, even when they were not feeling especially happy.[5]

The action of the pupil corresponds to mood and communicate the mood of a person when observed. Research has found that people have no control over their pupils, which involuntarily expand when expressing interest in another person or when looking at something.[6][better source needed] Normally, eyes instinctively blink at around 20 times per minute, but looking at a person the viewer finds attractive can make this rate faster.[7][better source needed]

Studies and behavioral experiments have shown that facial expressions and bodily expressions are congruent in terms of conveying visible signs of a person's emotional state, and that emotions can be judged with a high level of accuracy based on facial expressions.[8][9] At the same time, the brain processes another person's facial and bodily expressions simultaneously.[8]

Head and neck postures and signals

[edit]

The movement of the head can indicate various intentions and messages, and is often culture and context-dependent.

The angle of facing and positioning of a person's head can be indicative of their mood, when considered alongside with patterns of muscular tension that occur concurrently at the face and neck.[note 1] Tilting the head up may demonstrate 'superiority emotions' such as self-assurance, pride, or contempt.[12] When it is tilted down, this may indicate 'inferiority emotions' such as shame, shyness, or respect.[13] Nonetheless, the accuracy of such interpretation depends on the intensity of the feeling or other context-related factors. For instance, feelings of contentment may instead feature the head being angled down somewhat.[14]

In many cultures, nodding of the head is considered a sign of saying 'yes', while shaking the head is usually interpreted as meaning 'no'. In India, a head bobble is the tilting of the head from side to side, whose interpretation can be ambiguous and context-dependent.[15][better source needed]

A tilting of the head to the side can be an expression of interest in what the other person is communicating. It may be a sign of curiosity, uncertainty, or questioning. If the head is propped up by the hand when the head is tilted then this may indicate disinterest or be a sign of thinking about something. A head that is tilted forwards slightly while being pulled backward may indicate being suspicious.[16][better source needed]

As a person's vocal chords are influenced physically by the tilt of their head and the respective pattern of muscle tension, it is possible to discern their head tilt by listening to how they talk.[17][better source needed]

General body postures

[edit]

Emotions can also be detected through body postures. Research has shown that body postures are more accurately recognized when an emotion is compared with a different or neutral emotion.[18] For example, a person feeling angry would portray dominance over the other, and their posture would display approach tendencies. Comparing this to a person feeling fearful: they would feel weak, and submissive and their posture would display avoidance tendencies.[18]

Sitting or standing postures also indicate one's emotions. A person sitting still in the back of their chair, leaning forward with their head nodding along with the discussion implies that they are open, relaxed and generally ready to listen. On the other hand, a person who has their legs and arms crossed with the foot kicking slightly implies that they are feeling impatient and emotionally detached from the discussion.[19][better source needed] In a standing discussion, a person standing with arms akimbo with feet pointed towards the speaker could suggest that they are attentive and interested in the conversation.[19][better source needed]

In Bali, standing with arms akimbo is considered rude and may send signals of aggression.[20]

Chest

[edit]

In general, the relative fullness or shallowness of the chest, especially around the sternum, can be a key indicator of both mood and attitude.

When the body language of the chest is assessed in everyday circumstances, it involves an instinctive assessment of these factors of shape and volume. When the posture of the chest is fuller, and it is positioned relatively forward, then this is a sign of confidence. If it is thrusting prominently forward, then this may be an indication that the person wants to be socially prominent and make a statement of physical confidence. When the chest is pulled back then this can indicate a less confident attitude.[citation needed]

If a person positions their chest closer towards another person it may be a sign of paying closer attention to them as part of a conversation, or, in other circumstances, it may be a sign of physical assertion and aggression.[21]

Gestures

[edit]

Gestures are movements made with body parts and may be voluntary or involuntary.[19][better source needed]

Arm gestures can be interpreted in several ways. In a discussion, when one stands, sits or even walks with folded arms, it is normally not a welcoming gesture. It could mean that they have a closed mind and are most likely unwilling to listen to the speaker's viewpoint. Another type of arm gesture also includes an arm crossed over the other, demonstrating insecurity and a lack of confidence.[19][better source needed] Hand gestures often signify the state of well-being of the person making them. Relaxed hands indicate confidence and self-assurance, while clenched hands may be interpreted as signs of stress or anger. If a person is wringing their hands, this demonstrates nervousness and anxiety.[19][better source needed]

Finger gestures are also commonly used to exemplify one's speech as well as denote the state of well-being of the person making them. In certain cultures, pointing using one's index finger is deemed acceptable. However, pointing at a person may be viewed as aggressive in other cultures – for example, people who share Hindu beliefs consider finger pointing offensive. Instead, they point with a palm up open hand.[22] Likewise, the thumbs up gesture could show "OK" or "good" in countries like the United States, South Africa, France, Lebanon and Germany. But this same gesture is insulting in other countries like Iran, Bangladesh and Thailand, where it is the equivalent of showing the middle finger in some cultures.[22]

It is difficult to distinguish a behavior motivated by an out-group bias—a negative response to a member of a different group—from one fueled by stereotype effect—a cognitive association between members of a specific out-group and a culturally held belief.[23][clarification needed]

Handshakes

[edit]

Handshakes are regular greeting rituals and commonly used when meeting, greeting, offering congratulations, expressing camaraderie, or after the completion of an agreement.[citation needed]

Studies have categorized several handshake styles, including the finger squeeze, the bone crusher (shaking hands too strongly), the limp fish (shaking hands too weakly), etc.[22] Handshakes are popular in the United States and are appropriate for use between men and women. However, in Muslim cultures, men may not shake hands or touch women in any way and vice versa. Likewise, in Hindu cultures, Hindu men may never shake hands with women. Instead, they greet women by placing their hands as if praying.[citation needed]

A firm, friendly handshake has long been recommended in the business world as a way to make a good first impression, and the greeting is thought to date to ancient times as a way of showing a stranger you had no weapons.[24]

Breathing

[edit]

Body language related to breathing and patterns of breathing can be indicative of a person's mood and state of mind.[citation needed]

Other subcategories

[edit]

Oculesics

[edit]
Main article: Oculesics

Oculesics, a subcategory of body language, is the study of eye movement, eye behavior, gaze, and eye-related nonverbal communication.

As a social or behavioral science, oculesics is a form of nonverbal communication focusing on deriving meaning from eye behavior.[25] Oculesics is culturally dependent. For example, in traditional Anglo-Saxon culture, avoiding eye contact usually portrays a lack of confidence, certainty, or truthfulness.[26] However, in the Latino culture, direct or prolonged eye contact means that you are challenging the individual with whom you are speaking or that you have a romantic interest in the person.[26] Also, in many Asian cultures, prolonged eye contact may be a sign of anger or aggression.

Haptics

[edit]
Main article: Haptic communication

Research has also shown that people can accurately decode distinct emotions by merely watching others communicate via touch.[27] A study by Jones and Yarbrough[28] regarded communication with touch as the most intimate and involving form which helps people to keep good relationships with others. For example, Jones and Yarbrough explained that strategic touching is a series of touching usually with an ulterior or hidden motive thus making them seem to be using touch as a game to get someone to do something for them.[28]

Heslin outlines five haptic categories:[29]

  • Functional/professional: This expresses task-orientation.
  • Social/polite: This expresses ritual interaction.
  • Friendship/warmth: This expresses idiosyncratic relationship.[clarification needed]
  • Love/intimacy: This expresses emotional attachment. Public touch can serve as a 'tie sign' that shows others that your partner is "taken".[30] When a couple is holding hands, putting their arms around each other, this is a 'tie sign' showing others that they are together. The use of 'tie signs' are used more often by couples in the dating and courtship stages than between their married counterparts.[31]
  • Sexual/arousal: This expresses sexual intent.

Proxemics

[edit]
Main article: Proxemics

Another notable area in the nonverbal world of body language is that of spatial relationships, which is also known as proxemics. Introduced by Edward T. Hall in 1966, proxemics is the study of measurable distances between people as they interact with one another.[32] Hall came up with four distinct zones in which most people operate:[32]

Intimate distance for embracing, touching or whispering

Close phase – less than 6 inches (15 cm)
Far phase – 6 to 18 inches (15 to 46 cm)

Personal distance for interactions among good friends or family members

Close phase – 1.5 to 2.5 feet (46 to 76 cm)
Far phase – 2.5 to 4 feet (76 to 122 cm)

Social distance for interactions among acquaintances

Close phase – 4 to 7 feet (1.2 to 2.1 m)
Far phase – 7 to 12 feet (2.1 to 3.7 m)

Public Distance used for public speaking

Close phase – 12 to 25 feet (3.7 to 7.6 m)
Far phase – 25 feet (7.6 m) or more.

In addition to physical distance, the level of intimacy between conversants can be determined by "socio-petal socio-fugal axis", or the "angle formed by the axis of the conversants' shoulders".[33]

Changing the distance between two people can convey a desire for intimacy, declare a lack of interest, or increase/decrease domination.[34] It can also influence the body language that is used. For example, when people talk they like to face each other. If forced to sit side by side, their body language will try to compensate for this lack of eye-to-eye contact by leaning in shoulder-to-shoulder.[34]

As with other types of body language, proximity range varies with culture. Hall suggested that "physical contact between two people ... can be perfectly correct in one culture, and absolutely taboo in another".[35]

Tone of voice

[edit]
Main article: Emotional prosody

Certain body postures can significantly influence the tone of voice. The intra-abdominal pressure (IAP) is a direct influence on, and discernible in, tone of voice. Hands-free devices which use a digital voice, such as Amazon's Alexa, tend to omit or limit the sound of IAP from the digital voice. The voice therefore lacks a human-like fullness of tone and sounds more robotic.

Attitude

[edit]
Mehrabian's rule : Verbal 7% , Tonal 38% , and body language 55%
Mehrabian's rule

Human communication is extremely complex and one must look at the whole in order to make any determination as to the attitudes being expressed.[36]

Body language is a major contributor to the attitude a person conveys to others. Albert Mehrabian maintains that during a conversation dealing with feelings and attitudes (i.e., like-dislike), 7% of what is communicated is via what is said, 38% is via tone of voice, and the majority, 55%, is via body language. This is also referred to as the '7%–38%–55% Rule',[37] and is often considered in studies of human communications. While there is a wider debate about the percentage share which should be attributed to each of the three contributing factors, it is generally agreed upon that body language plays a fundamental role in determining the attitude a person conveys.

A person may alter their body language in order to alter the attitude they convey; this may in turn influence the rapport they have with another person. Whether a formal or informal attitude is conveyed may influence the other person's response.[citation needed]

Trust

[edit]

Body language which expresses trust will usually convey a sense of openness and warmth. Contrarily, mistrusting body language will appear relatively closed and cold. Body language which conveys a sense of trust can vary depending on the nature of the relationship.[38][39][better source needed]

Business

[edit]

Body language which conveys trust in a business context is done so in a formal manner and in line with business etiquette.[40][better source needed]

Friendship

[edit]
Main article: Friendship

Body language between friends is typically more expressive and informal than body language in business.[41][better source needed]

Intimate relationships

[edit]
Main article: Intimate relationship

The body language of trust in intimate relationships such as courtship and marriage is very open and often highly personalised, even if it is not necessarily as physically dynamic as that found in a friendship for example. In Western contexts holding hands is a common sign between intimate partners that expresses their affection and trust in each other. Trust is also conveyed in intimate relationships through people caressing and kissing each other. These actions are designed to convey openness and warmth in a highly personalised way. Each partner is communicating to the other that they are attracted to them and also that they trust them and are allowing them to touch them in a more intimate way than would otherwise be acceptable. Such body language may be established gradually over a period of courtship. The body language of intimate relationships cannot be used acceptably in non-intimate relationships.[42]

When people are in an intimate relationship, they often position themselves closer to each other than if they were in a different kind of relationship. Even though it may only be a small distance closer together, an observer can interpret this additional closeness to mean that they are in an intimate relationship. For example, spouses may sit, stand, and walk in each other's intimate space, whereas business colleagues may maintain more of a distance and outside of each other's intimate space. As the spouses are in an intimate relationship, they do not feel the need to maintain the same distance as the business colleagues.[43]

Readiness

[edit]

When you get onto a basketball court, all your teammates beside you, pumped up and ready to go, you form impressions of the other side, their strength and unity, their mood and body language. Of course the physicality element is stronger in sport, but something similar happens in politics, where you can read the mood of one side or the other simply by looking at them, sitting there all together.[44]

Body language can convey the impression of a readiness to take action. While this is always observable in the physical sense it can be further categorised as being 'readiness for physical exertion' or 'readiness for social interaction'. Noting that a person will typically be ready for both at any given time, and such categorisations are based upon which course of action they are primarily ready for at that moment. Such states of readiness influence the person's whole body, tone of voice, and what impression they convey through their body language. A state of increased readiness may also be referred to as being in a state of high energy or intensity. Relative to states of unreadiness, most states of readiness typically involve a deeper breathing pattern, increased excitation of the nervous system, and an increased heart rate.[44] Such physiological effects also influence the person's skin and its fullness of appearance. In relative terms, a person's skin will usually look fuller and more taut while in a state of readiness, and thinner and more flaccid in a state of unreadiness. A readiness for physical exertion typically means that these effects are increased further in terms of their intensity and visual prominence.

Readiness for social interaction

[edit]

Harvard professor Amy Cuddy suggested in 2010 that two minutes of power posing – "standing tall, holding your arms out or toward the sky, or standing like Superman, with your hands on hips" – could increase confidence,[45] but retracted the advice and stopped teaching it after a 2015 study was unable to replicate the effect.[46]

Universal vs. culture-specific

[edit]

Scholars have long debated on whether body language, particularly facial expressions, are universally understood. In Darwin's evolutionary theory, he postulated that facial expressions of emotion are inherited.[47] On the other hand, scholars have questioned if culture influences one's bodily expression of emotions. Broadly, the theories can be categorized into two models: the cultural equivalence model and cultural advantage model.

Cultural equivalence model

[edit]

The cultural equivalence model predicts that "individuals should be equally accurate in understanding the emotions of ingroup and outgroup members".[48] This model is rooted in Darwin's evolutionary theory, where he noted that both humans and animals share similar postural expressions of emotions such as anger/aggression, happiness, and fear.[48] These similarities support the evolution argument that social animals (including humans) have a natural ability to relay emotional signals with one another, a notion shared by several academics (Chevalier-Skolnikoff, 1974; Linnankoski, Laakso, Aulanko, & Leinonen, 1994). Where Darwin notes similarity in expression among animals and humans, the Cultural Equivalence Model notes similarity in expression across cultures in humans, even though they may be completely different.

One of the strongest pieces of evidence that supports this model was a study conducted by Paul Ekman, where members of a preliterate tribe in Papua New Guinea reliably recognized the facial expressions of individuals from the United States. Culturally isolated and with no exposure to US media, there was no possibility of cross-cultural transmission to the Papuan tribesmen.[49]

The term body language is usually applied in regard to people but may also be applied to animals.[50]

Cultural advantage model

[edit]

On the other hand, the cultural advantage model predicts that individuals of the same race "process the visual characteristics more accurately and efficiently than other-race faces".[51] Other factors that increase accurate interpretation include familiarity with nonverbal accents.[52]

There are numerous studies that support both the cultural equivalence model and the cultural advantage model, but reviewing the literature indicates that there is a general consensus that seven emotions are universally recognized, regardless of cultural background: happiness, surprise, fear, anger, contempt, disgust, and sadness.[53]

Recently, scholars have shown that the expressions of pride and shame are universal. Tracy and Robins (2008) concluded that the expression of pride includes an expanded posture of the body with the head tilted back, with a low-intensity face and a non-Duchenne smile (raising the corner of the mouth). The expression of shame includes the hiding of the face, either by turning it down or covering it with the hands.[49]

Applications

[edit]

Fundamentally, body language is seemed as an involuntary and unconscious phenomenon that adds to the process of communication.[54] Despite that, there have been certain areas where the conscious harnessing of body language – both in action and comprehension – have been useful. The use of body language has also seen an increase in application and use commercially, with large volumes of books and guides published designed to teach people how to be conscious of body language, and how to use it to benefit them in certain scenarios.[55]

The use of body language can be seen in a wide variety of fields. Body languages has seen applications in instructional teaching in areas such as second-language acquisition[56] and also to enhance the teaching of subjects like mathematics. A related use of body language is as a substitution to verbal language to people who lack the ability to use that, be it because of deafness or aphasia. Body language has also been applied in the process of detecting deceit through micro-expressions, both in law enforcement and even in the world of poker.[57]

Instructional teaching

[edit]

Second-language acquisition

[edit]

The importance of body language in second-language acquisition was inspired by the fact that to successfully learn a language is to achieve discourse, strategic, and sociolinguistic competencies.[58] Sociolinguistic competence includes understanding the body language that aids the use of a particular language. This is usually also highly culturally influenced. As such, a conscious ability to recognize and even perform this sort of body language is necessary to achieve fluency in a language beyond the discourse level.

The importance of body language to verbal language use is the need to eliminate ambiguity and redundancy in comprehension.[58] Pennycook (1985) suggests to limit the use of non-visual materials to facilitate the teaching of a second language to improve this aspect of communication. He calls this being not just bilingual but also 'bi-kinesic'.[59]

Enhancing teaching

[edit]

Body language can be a useful aid not only in teaching a second language, but also in other areas. The idea behind using it is as a nonlinguistic input.[60] It can be used to guide, hint, or urge a student towards the right answer. This is usually paired off with other verbal methods of guiding the student, be it through confirmation checks or modified language use. Tai[61] in his 2014 paper provides a list of three main characteristic of body language and how they influence teaching. The features are intuition, communication, and suggestion.

  • The intuitive feature of body language used in teaching is the exemplification of the language, especially individual words, through the use of matching body language. For example, when teaching about the word "cry", teachers can imitate a crying person. This enables a deeper impression which is able to lead to greater understanding of the particular word.[61]
  • The communicative feature is the ability of body language to create an environment and atmosphere that is able to facilitate effective learning. A holistic environment is more productive for learning and the acquisition for new knowledge.[61]
  • The suggestive feature of body language uses body language as a tool to create opportunities for the students to gain additional information about a particular concept or word through pairing it with the body language itself.[61]

Detecting deceit

[edit]

Law enforcement

[edit]

Despite the absence of evidence indicating that non-verbal lie detection works — and its rejection by the scholarly community as an effective way to detect lies — many law enforcement bodies still rely on it.[62] Numerous Federal Bureau of Investigation Law Enforcement Bulletins have addressed body language as a purported tool for "evaluation truthfulness and detecting deception."[63][64]

The body language of the members of law enforcement might influence the accuracy of eyewitness accounts.[65]

Poker

[edit]

The game of poker involves the competence of reading and analyzing the body language of opponents (for example, poker tells), and moderating one's own body language (for example, poker bluff).

Visual arts

[edit]
Folded arms and looking away, in body language, can be interpreted as insecurity.
Folding your arms and looking away, in body language, can be interpreted as insecurity. The exaggerated use of the gesture by both characters is used to create a comedic impression.

Exaggerated, repetitious, and inappropriate body language is often used to achieve a humorous effect in comedy productions. Comedy double acts often use methods of complementary and contrasting comedic body language. [66]

Kinesics

[edit]
Main article: Kinesics

Kinesics is the study and interpretation of nonverbal communication related to the movement of any part of the body or the body as a whole.[67] It was first deveoped by Ray Birdwhistell, who disavowed use of the term body language, as it did not meet the linguistic definition of language.[68]

Birdwhistell pointed out that "human gestures differ from those of other animals in that they are polysemic, that they can be interpreted to have many different meanings depending on the communicative context in which they are produced". And, he "resisted the idea that 'body language' could be deciphered in some absolute fashion". He also indicated that "every body movement must be interpreted broadly and in conjunction with every other element in communication".[68]

Notes

[edit]
  1. ^ For example, the posture of the body has a corresponding pattern of muscle tension i.e. how muscles in the face and neck are contracted or relaxed while the person's head is tilted. This relationship is instinctively observed in conjunction with a person's posture. Men and women have been found to be perceived differently in regard to this relationship between posture and muscle tension.[10] According to Alain Mignault and Avi Chaudhuri and considered in regard to smiling:

    Indeed, a bowed head probably leads raters to perceive the contraction of the Zygomatic Major (Action Unit 12) and a raised head to perceive the contraction of the Triangularis (Action Unit 15). Second, although we found no significant difference in the perception of mouth contraction at zero degrees between male and female actors, a large difference is perceived at other head angles even though the expression itself is fixed.[11]

    Such a correspondence can be deliberately manipulated to produce different effects. For example, an actor can pose in a confident manner, while relaxing muscles in the neck which would ordinarily be more contracted in conjunction with the pose. He may thereby make it appear that he is actually afraid and the pose is merely an attempt to appear confident.

Similarly, investigators' unintentional cues (e.g., body language, tone of voice) may negatively impact the reliability of eyewitness evidence. Psychology researchers have noted that such influences could be avoided if 'blind' identification procedures were employed (i.e., procedures conducted by investigators who do not know the identity of the actual suspect). However, blind procedures, which are used in science to prevent inadvertent contamination of research results, may be impractical for some jurisdictions to implement.
