This article discusses how both verbal and body language can indicate deceit in conversation. Although there is no established method of lie detection, many psychologists are working towards creating a more accurate system to do so using a combination of technology that analyzes facial expression, speech patterns, and more.

"A small band of linguists, engineers and computer scientists, among others, are busy training computers to recognize hallmarks of what they call emotional speech - talk that reflects deception, anger, friendliness and even flirtation. ... Algorithms developed by Dr. Hirschberg and colleagues have been able to spot a liar 70 percent of the time in test situations, while people confronted with the same evidence had only 57 percent accuracy ... His lab has also found ways to use vocal cues to spot inebriation, though it hasn't yet had luck in making its computers detect humor - a hard task for the machines, he said."

This article by Candice Jalili on Time discusses the body language people tend to have when lying. Everyone can lie, in fact, the average American tells one to two lies each day. It explains how to detect honesty in a conversation, including where their eyes go and how their voice sounds. When someone is lying, they are likely uncomfortable, so they may fidget or have frequent voice cracks. Doctors from the healthcare community provide input on signs people display when lying. The main sections of this article are body cues, facial cues, tone of voice, and content of speech. Body cues include hand movement and itching/fidgeting. Facial cues are eye movement, mouth position, change in complexion, and sweating. The section on tone of voice consists of a high pitched voice and changes in volume while speaking. Lastly, content of speech includes phrases people use, filler words, and slip-ups.

Parents teach their children to lie. The teaching process is subtle but just as effective as if they had sent their children to formal classes in deception. How many times have parents told their kids "Look me in the eye and then tell me what you did?"

Research demonstrates that liars maintain more deliberate eye contact than do truthful people.

Dr. Joy Hirsch, head of Memorial Sloan-Kettering Hospital's functional M.R.I. Laboratory, and her graduate student, Karl Kim, found that second languages are stored differently in the human brain, depending on when they are learned. Babies who learn two languages simultaneously, and apparently effortlessly, have a single brain region for generating complex speech, researchers say. But people who learn a second language in adolescence or adulthood possess two such brain regions, one for each language. To explore where languages lie in the brain, Dr. Hirsch recruited 12 healthy bilingual people from New York City. Ten different languages were represented in the group. Half had learned two languages in infancy. The other half began learning a second language around age 11 and had acquired fluency by 19 after living in the country where the language was spoken. With their heads inside the M.R.I. machine, subjects thought silently about what they had done the day before using complex sentences, first in one language, then in the other. The machine detected increases in blood flow, indicating where in the brain this thinking took place. Activity was noted in Wernicke's area, a region devoted to understanding the meaning of words and the subject matter of spoken language, or semantics, as well as Broca's area, a region dedicated to the execution of speech, as well as some deep grammatical aspects of language. None of the 12 bilinguals had two separate Wernicke's areas, Dr. Hirsch said. But there were dramatic differences in Broca's areas, Dr. Hirsch said. In people who had learned both languages in infancy, there was only one uniform Broca's region for both languages, a dot of tissue containing about 30,000 neurons. Among those who had learned a second language in adolescence, however, Broca's area seemed to be divided into two distinct areas. Only one area was activated for each language. These two areas lay close to each other but were always separate, Dr. Hirsch s

This article discusses the language of lying. It talks about liars' tendencies and patterns. Lying is very complex, but language itself is very good lie-detector.
