Deception is the act of convincing one or many recipients of untrue information. The person creating the deception knows it to be false while the receiver of the message has a tendency to believe it. It is often done for personal gain or advantage. Deception can involve dissimulation, propaganda and sleight of hand as well as distraction, camouflage or concealment. There is also self-deception. It can also be called, with varying subjective implications, beguilement, deceit, bluff, mystification, ruse, or subterfuge.
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.
Paul Ekman is an American psychologist and professor emeritus at the University of California, San Francisco who is a pioneer in the study of emotions and their relation to facial expressions. He was ranked 59th out of the 100 most eminent psychologists of the twentieth century in 2002 by the Review of General Psychology.
A microexpression is a facial expression that only lasts for a short moment. It is the innate result of a voluntary and an involuntary emotional response occurring simultaneously and conflicting with one another, and occurs when the amygdala responds appropriately to the stimuli that the individual experiences and the individual wishes to conceal this specific emotion. This results in the individual very briefly displaying their true emotions followed by a false emotional reaction.
Nonverbal communication 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, 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 noted. Today, scholars argue that nonverbal communication can convey more meaning than verbal communication.
Relational frame theory (RFT) is a psychological theory of human language, cognition, and behaviour. It was developed originally by Steven C. Hayes of University of Nevada, Reno and has been extended in research, notably by Dermot Barnes-Holmes and colleagues of Ghent University.
Lie detection is an assessment of a verbal statement with the goal to reveal a possible intentional deceit. Lie detection may refer to a cognitive process of detecting deception by evaluating message content as well as non-verbal cues. It also may refer to questioning techniques used along with technology that record physiological functions to ascertain truth and falsehood in response. The latter is commonly used by law enforcement in the United States, but rarely in other countries because it is based on pseudoscience.
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.
Statement analysis is a technique used to determine whether a suspect is telling the truth or being deceptive based on linguistic indicators. The basic principles of statement analysis are straightforward: a suspect always reveals much more than they realize. Language moves so quickly that no one has complete control over what they say and try to conceal.

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.
Relational transgressions occur when people violate implicit or explicit relational rules. These transgressions include a wide variety of behaviors. The boundaries of relational transgressions are permeable. Betrayal for example, is often used as a synonym for a relational transgression. In some instances, betrayal can be defined as a rule violation that is traumatic to a relationship, and in other instances as destructive conflict or reference to infidelity.
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.

Truth-default theory (TDT) is a communication theory which predicts and explains the use of veracity and deception detection in humans. It was developed upon the discovery of the veracity effect - whereby the proportion of truths versus lies presented in a judgement study on deception will drive accuracy rates. This theory gets its name from its central idea which is the truth-default state. This idea suggests that people presume others to be honest because they either don't think of deception as a possibility during communicating or because there is insufficient evidence that they are being deceived. Emotions, arousal, strategic self-presentation, and cognitive effort are nonverbal behaviors that one might find in deception detection. Ultimately this theory predicts that speakers and listeners will default to use the truth to achieve their communicative goals. However, if the truth presents a problem, then deception will surface as a viable option for goal attainment.
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.
