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.

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.

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.

Despite contrary belief, there are not many tip-offs to whether or not someone is lying. There are not usually any clear indicators that can tell you right off the bat if someone is lying. There are different pieces to be put together. There is a whole language to lying and understanding what liars say is just the first step.

This article started off talking about research that was done on people lying in a foreign languages and their own native language. There were two contradicting theories found, but when an experiment was conducted, it was found that lying is easier in a foreign language. This was due to the theory that a foreign language is less emotionally arousing, therefore making it a little easier to tell a lie.

This article by Psychology Today is about phrases people say that may signifiy deceit. However, there are no verbal cues that can accurately predict that someone is lying. Some phrases that were mentioned in the article are "why would I do that", "that's about it", and " are you accusing me".

This New York Post article discusses strategies to tell when someone is lying. It provides tips on how to detect a liar, like what details they won't be able to provide. It also discusses a study conducted by the University of Amsterdam. This study describes nine experiments where 1,445 people needed to determine whether handwritten letters, videos, and interviews, both pre-recorded and live, were discussing true or false information. It also discusses the accuracy of polygraphs and how our intuition and attention to detail can help us determine if someone is being truthful or not.

Launches a flash application in which you can watch muscles of the face engage to reveal certain emotions...useful in detection of lying or "fake smiles."

Lying words: predicting deception from linguistic styles.

An insightful look at the process of lying, done by Hank Green on Scishow.

By analyzing linguistic texts, experts have observed four common patterns in the way people use language when they lie. Liars tend to employ devices such as speaking in third person, using negative terms, referring to others more than themselves, and over-complicating their stories.

Just a few decades ago, many linguists thought the human brain had evolved a special module for language . It seemed plausible that our brains have some unique structure or system. After all, no animal can use language the way people can. However, in the 1990s, scientists began testing the language-module theory using "functional" MRI technology that let them watch the brain respond to words. And what they saw didn't look like a module, says Benjamin Bergen, a researcher at the University of California, San Diego, and author of the book _Louder Than Words_. "They found something totally surprising," Bergen says. "It's not just certain specific little regions in the brain, regions dedicated to language, that were lighting up. It was kind of a whole-brain type of process." The brain appears to be taking words, which are just arbitrary symbols, and translating them into things we can see or hear or do; language processing, rather than being a singular module, is "a highly distributed system" encompassing many areas of the brain. Our sensory experiences can also be applied to imagining novel concepts like "flying pigs". Our sensory capacities, ancestral features shared with our primate relatives, have been co-opted for more recent purposes, namely words and language. Bergen comments, "What evolution has done is to build a new machine, a capacity for language, something that nothing else in the known universe can do," he says. "And it's done so using the spare parts that it had lying around in the old primate brain."

"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."
