WHO CAN CATCH A LIAR?’, Ekman and O’Sullivan, 1991.

Who can grab a liar? ', Ekman and O'Sullivan, 1991. What is the definition of lying or deceiving? Although fraud can be defined in several ways, Vrij (Vrij, 2000, p. 6) calls it a deliberate attempt of success or failure and creates it with a different idea without warning, Communicator thinks This idea is not true. Lying is an event of everyday life that changes considerably and complicatedly depending on the circumstances of individuals and the situation in which they are scammed. People tell lies for various reasons.

In many cases, however, it is important to know the person lying if a liar wants you. At that time, Ekman said his lie detection system can teach anyone with a correct rate of over 95%. His overall view is almost opposite to brain makers like Langleben and Vendemia's. Ekman is not a neuron that focused on liars, but a long time watching the face of a liar. The facial motion coding system is the key to the Ekman strategy. The basic emotion leads to a unique expression and only a few real really good liars are hidden. A part of lying is pretending to be a face. And it is consistent with a lie. However, Ekman says that even a fraudster who has practiced may not be able to control "leakage" of actual emotions. These micro expressions show a contradiction between the convolver's word and his emotions.

According to Ekman and Sullivan (1991), the facial feedback hypothesis is an important determinant of emotional experience. The author adds that facial feedback assumes that an individual can use his or her own face behavior information to figure his or her emotions. The face feedback hypothesis also claims that emotional expression causes behavioral changes that cause autonomy, hormones, and emotional experiences (Brody, 2001). Individuals use expressions as clues to the emotions they are experiencing or to judge their attitudes (Brody, 2001). A positive expression shows a more positive reaction than a person who shows an angry expression, such as understanding rather than anger (Brody, 2001). Emotional experience occurs when unpredictable changes in personal goals are achieved (Stein, Hernandez, & Trabasso, 2008)
