Body language is a type of 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. The term body language is usually applied in regard to people but may also be applied to animals. The study of body language is also known as kinesics. Although body language is an important part of communication, most of it happens without conscious awareness.
Nonverbal communication (NVC) is the transmission of messages or signals through a nonverbal platform such as eye contact (oculesics), body language (kinesics), social distance (proxemics), touch (haptics), voice (paralanguage), physical environments/appearance, and use of objects. When communicating, we utilize nonverbal channels as means to convey different messages or signals, whereas others can interpret these message. The study of nonverbal communication started in 1872 with the publication of The Expression of the Emotions in Man and Animals by Charles Darwin. Darwin began to study nonverbal communication as he noticed the interactions between animals such as lions, tigers, dogs etc. and realized they also communicated by gestures and expressions. For the first time, nonverbal communication was studied and its relevance questioned. Today, scholars argue that nonverbal communication can convey more meaning than verbal communication.
Unconsciouscommunication is the subtle, unintentional, unconscious cues that provide information to another individual. It can be verbal l or it can be non-verbal. Some psychologists instead use the term honest signals because such cues are involuntary behaviors that often convey emotion whereas body language can be controlled. Many decisions are based on unconscious communication, which is interpreted and created in the right hemisphere of the brain. The right hemisphere is dominant in perceiving and expressing body language, facial expressions, verbal cues, and other indications that have to do with emotion but it does not exclusively deal with the unconscious.
Kinesics is the interpretation of body communication such as facial expressions and gestures, nonverbal behavior related to movement of any part of the body or the body as a whole. The equivalent popular culture term is body language, a term Ray Birdwhistell, considered the founder of this area of study, neither used nor liked.
Albert Mehrabian is Professor Emeritus of Psychology at the University of California, Los Angeles. He is best known for his publications on the relative importance of verbal and nonverbal messages.
Expectancy violations theory (EVT) is a theory of communication that analyzes how individuals respond to unanticipated violations of social norms and expectations. The theory was proposed by Judee K. Burgoon in the late 1970s and continued through the 1980s and 1990s as "nonverbal expectancy violations theory", based on Burgoon's research studying proxemics. Burgoon's work initially analyzed individuals' allowances and expectations of personal distance and how responses to personal distance violations were influenced by the level of liking and relationship to the violators. The theory was later changed to its current name when other researchers began to focus on violations of social behavior expectations beyond nonverbal communication.
Dyssemia is a difficulty with receptive and/or expressive nonverbal communication. The word comes from the Greek roots dys (difficulty) and semia (signal). The term was coined by psychologists Marshall Duke and Stephen Nowicki in their 1992 book, Helping The Child Who Doesn't Fit In, to decipher the hidden dimensions of social rejection. These difficulties go beyond problems with body language and motor skills. Dyssemic persons exhibit difficulties with the acquisition and use of nonverbal cues in interpersonal relationships. "A classic set of studies by Albert Mehrabian showed that in face-to-face interactions, 55 percent of the emotional meaning of a message is expressed through facial, postural, and gestural means, and 38 percent of the emotional meaning is transmitted through the tone of voice. Only seven percent of the emotional meaning is actually expressed with words." Dyssemia represents the social dysfunction aspect of nonverbal learning disorder.
Surprise is a brief mental and physiological state, a startle response experienced by animals and humans as the result of an unexpected event. Surprise can have any valence; that is, it can be neutral/moderate, pleasant, unpleasant, positive, or negative. Surprise can occur in varying levels of intensity ranging from very-surprised, which may induce the fight-or-flight response, or little-surprise that elicits a less intense response to the stimuli.
Interpersonal deception theory (IDT) is one of a number of theories that attempts to explain how individuals handle actual deception at the conscious or subconscious level while engaged in face-to-face communication. The theory was put forth by David Buller and Judee Burgoon in 1996 to explore this idea that deception is an engaging process between receiver and deceiver. IDT assumes that communication is not static; it is influenced by personal goals and the meaning of the interaction as it unfolds. IDT is no different from other forms of communication since all forms of communication are adaptive in nature. The sender's overt communications are affected by the overt and covert communications of the receiver, and vice versa. IDT explores the interrelation between the sender's communicative meaning and the receiver's thoughts and behavior in deceptive exchanges.
Language expectancy theory (LET) is a theory of persuasion. The theory assumes language is a rules-based system, in which people develop expected norms as to appropriate language usage in given situations. Furthermore, unexpected linguistic usage can affect the receiver's behavior resulting from attitudes towards a persuasive message.
Most investigators accept the definition of language intensity proposed by John Waite Bowers: a quality of language that "indicates the degree to which toward a concept deviates from neutrality." Intensity as a lexical variable in communication studies has generated extensive empirical research.
Judee K. Burgoon is a professor of communication, family studies and human development at the University of Arizona, where she serves as director of research for the Center for the Management of Information and site director for the NSF-sponsored Center for Identification Technology Research. She is also involved with different aspects of interpersonal and nonverbal communication, deception, and new communication technologies. She is also director of human communication research for the Center for the Management of Information and site director for Center for Identification Technology Research at the university, and recently held an appointment as distinguished visiting professor with the department of communication at the University of Oklahoma, and the Center for Applied Social Research at the University of Oklahoma. Burgoon has authored or edited 13 books and monographs and has published nearly 300 articles, chapters and reviews related to nonverbal and verbal communication, deception, and computer-mediated communication. Her research has garnered over $13 million in extramural funding from the National Science Foundation, the Department of Defense, the Department of Homeland Security, the Office of the Director of National Intelligence, Counterintelligence Field Activity, and the National Institutes of Mental Health. Among the communication theories with which she is most notably linked are: interpersonal adaptation theory, expectancy violations theory, and interpersonal deception theory. A recent survey identified her as the most prolific female scholar in communication in the 20th century.
Cognitive valence theory (CVT) is a theoretical framework that describes and explains the process of intimacy exchange within a dyad relationship. Peter A. Andersen, PhD created the cognitive valence theory to answer questions regarding intimacy relationships among colleagues, close friends and intimate friends, married couples and family members. Intimacy or immediacy behavior is that behavior that provides closeness or distance within a dyad relationship. Closeness projects a positive feeling in a relationship, and distance projects a negative feeling within a relationship. Intimacy or immediacy behavior can be negatively valenced or positively valenced. Valence, associated with physics, is used here to describe the degree of negativity or positivity in expected information. If your partner perceives your actions as negative, then the interaction may repel your partner away from you. If your partner perceives your actions as positive, then the interaction may be accepted and may encourage closeness. Affection and intimacy promotes positive valence in a relationship. CVT uses non-verbal and verbal communications criteria to analyze behavioral situations.
Non-verbal leakage is a form of non-verbal behavior that occurs when a person verbalizes one thing, but their body language indicates another, common forms of which include facial movements and hand-to-face gestures. The term "non-verbal leakage" got its origin in literature in 1968, leading to many subsequent studies on the topic throughout the 1970s, with related studies continuing today.
Power and dominance-submission are two key dimensions of relationships, especially close relationships in which parties rely on one another to achieve their goals and as such it is important to be able to identify indicators of dominance.
Body-to-body communication is a way of communicating with others through the use of nonverbal communication, without using speech or verbalization. It can include body language, facial expressions, and other bodily gestures in order to communicate with others without the need of verbal communication. Body-to-body communication accounts for postures, body language, physical touch, nonverbal language, and other bodily gestures.
Social cues are verbal or non-verbal signals expressed through the face, body, voice, motion and guide conversations as well as other social interactions by influencing our impressions of and responses to others. These percepts are important communicative tools as they convey important social and contextual information and therefore facilitate social understanding.
Affiliative conflict theory (ACT) is a social psychological approach that encompasses interpersonal communication and has a background in nonverbal communication. This theory postulates that "people have competing needs or desires for intimacy and autonomy". In any relationship, people will negotiate and try to rationalize why they are acting the way they are in order to maintain a comfortable level of intimacy.
Social Mirror Theory (SMT) states that people are not capable of self-reflection without taking into consideration a peer's interpretation of the experience. In other words, people define and resolve their internal musings through other's viewpoint. SMT's background is derived from the 1800s from concepts related to the study of public opinion and social interaction by Wilhelm Dilthey, the German philosopher and sociologist.
Motivation impairment effect (MIE) is a hypothesised behavioral effect relating to the communication of deception. The MIE posits that people who are highly motivated to deceive are less successful in their goal when their speech and mannerisms are observed by the intended audience. This is because their nonverbal cues, such as adaptor gestures, sweating, kinesic behaviors, verbal disfluencies, etc, tend to be more pronounced due to increased stress, cognitive load, and heightened emotional state. There is some disagreement regarding the MIE hypothesis, with a few nonverbal communication scholars arguing that deception should not be examined as separate for senders and receivers, but rather as an integral part of the overall process.
