Liar Liar: Micro Expression Application to Detect Deception Andrew Batiuk Linfield College Abstract This study focused on nonverbal micro expressions as a deception identification method to shed light on the effectiveness of such a tool for use in detecting lies. Five examples of videos depicting instances in which individuals who were later proven to be lying were analyzed in order to assess the reliability of such a tool in an area of interest to researchers in both communication and psychology. This study suggested that the theory provides a reliable tool for assessing the use of deception by a variety of people in different situations. The paper upon which this poster was based was written for the Senior Seminar course in Communication Arts. 2 Research Question • Does an individual’s use of micro expressions indicate they are lying? Artifacts • Four videos of individuals who were determined, after the fact, to be lying during the taped communication interaction • Craig Pusley • Bill Clinton • Unidentified Witness: Jimmy Kimmel- “Lie Witness News” • Alex Rodriguez • One video in which the individual was confirmed to be telling the truth during the taped communication interaction • Bill Clinton Method • Micro expressions are brief facial expressions lasting a fraction of a second. Seven have been identified. • Anger, fear, sadness, disgust, contempt, surprise and happiness. • Theorists • Haggard and Isaacs-1966 • Paul Ekman-1989 Micro Expression: Contempt • Expression of Contempt = One side of the mouth rises or pulls back Contempt Microexpression - YouTube https://i.ytimg.com/vi/WlrCfzI55io/maxresdefault.jpg Example of Analysis: Micro Expression Contempt • Craig Pusley • Contempt Fake Marine Caught Lying On Camera - Phony Marine Craig Pusley https://www.youtube.com/watch?v=uV9YU8D2k5I Example of Analysis: Micro Expression Contempt • Alex Rodriguez • Contempt Alex Rodriguez Says He Never Did Steroids. Whoops. https://www.youtube.com/watch?v=n1ABIYViVLo Summary • Question: Does an individual’s use of micro expressions indicate they are lying? • In the full analysis, five micro expressions were determined to indicate lying in the selected artifacts. • Happiness, contempt, disgust, fear, and surprise • Micro expressions indicating lying were found in every artifact. 9 Conclusion • Most lies can be detected through analysis of nonverbal communication. • Micro expressions provide an effective method for detecting deception. • The method does not determine the reason for the deception, but can indicate its existence.
