The paper explores how verbal communications, facial expressions and body language can indicate deliberate deception and points out how each aspect of human communication relates to truthfulness and deception both in combination as well as individually. The paper describes how aspects of vocal intonation, facial expression, and body posture and gait are essential components of human communication that supplement verbal communication and when human beings are deliberately attempting to be deceptive in their communications, they employ characteristic mannerisms in all of those realms to help them achieve their intent. The paper notes that every aspect of human behavior with regard to deception detection provides the means to determine whether or not the individual is being truthful or deceptive alone, but, each has even more value when considered in specific relation to one another.

Deception Detection through Body Language Cues

From the Paper:

"Human beings are complex animals who communicate in much more complex ways than most other animal species. Our communication incorporates verbal language, facial expressions, and various aspects of our body language as well. Generally, there is a fundamental consistency between and among our words, facial expressions, and our body language. That is largely a function of the fact that the elements other than our choice of words are almost entirely involuntary in that we do them without conscious awareness. Nevertheless, there is a consistency between the truth of our statements (and other messages that we intend to communicate) and those aspects of our behavior that correspond to our spoken words; that is equally true whether we are speaking the truth or deliberately speaking untruths.
"To illustrate how communicative our non-verbal behavior typically is, all one needs to do is observe sets of strangers (ideally pairs of people walking together or communicating face to face) from far enough away that one cannot hear their words. It is relatively easy for even untrained individuals to identify with relative accuracy whether the strangers are happy or sad and whether they are in agreement or disagreement over the topic of their conversations just from observing their body postures and physical gestures."
