Transcript of Microexpressions Presentation
really tell when
someone is lying? What are microexpressions? Microexpressions are brief,
involuntary expressions of emotion. Microexpressions can last from 1/30 - 1/15 of a second Microexpressions can express any of the seven emotions universally expressed in the face: disgust, anger, fear, happiness, sadness, surprise and contempt. When were
discovered? In 1966, two psychological researchers by the names of Haggard and Isaacs discovered what they described as "micromomentary expressions" while reviewing film of couple therapy. Later, in 1969 and again in 1974, scientists Ekman and Friesen included these "micromomentary expressions" in their studies of deception, and coined the phrase microexpression. What do microexpressions look like? The seven universal facial expressions: DISGUST ANGER HAPPINESS SADNESS SURPRISE CONTEMPT Do experts like those on actually exist? Tim Roth's character Cal Lightman
is based on clinical psychologist Dr. Paul Ekman Dr. Ekman is an expert lie detector and has advised everyone from the Secret Service and the Department of Defense to Pixar on the science of reading facial expressions, much like the Lightman Group in Lie To Me. "But the science that he (Cal) does, and the applications, are exactly what I've been doing, particularly in the past five years, in applying this with law enforcement and national security." Can microexpressions really tell if someone is lying? There is no single behavior
indicative of deception. Micro expressions tell us what a person is feeling, but not why they are feeling it. Interpreting the emotions of others is necessary for accurate lie detection. The most commonly misinterpreted microexpression is fear. A flash of fear across a suspect's face can be used as evidence agaisnt him/her, yet the suspect could easily be innocent and simply afraid no one will believe him/her. look
