Microexpressions
The public has a grip on micro expressions, their significance in our overall understanding of body language, and more importantly, their relevance in eliminating deception.
Two researchers discovered, while looking at films of couples in therapy, what they described as micromomentary expressions. They noted behaviors that would flash by so quickly they were difficult to see except by slowing the film down. Years later, building on earlier work and observing these same behaviors, Paul Eckman coined the term micro expressions while studying deception.
Researchers found our faces often reveal hidden sentiments that are being intentionally concealed. Over time the term micro expressions grew to include too many things, failing, for instance, to differentiate between the truly miniscule, the small, and the larger facial distortions. There was a failure to differentiate between the behaviors that were fast and those which were super-fast, but which had little to do with being micro or small. Lastly there was a failure to differentiate behaviors that are asymmetrical or that oddly freeze in place such as when we hold a tense smile at a snarling Doberman Pincer.
There is no single behavior indicative of deception, in general.
