Lie to Me - a world famous TV serial made common people aware about how ability to detect tiniest movements of facial muscles could bring dramatic turn while interrogating suspects. Bringing a criminal into confessing crime it committed isn't easy because it tries to defend itself from being detected by law and enforcement agency. Investigators and forensic experts have to pick tiniest clues not only at actual crime scene but also on faces of people they interrogate or try to get information from.
A micro-expression or micro-momentary facial expression is nothing but movements of different facial expressions that unconsciously occurs within fraction of a second. Just like a macro or clearly detectable facial expressions, micro-expressions give away seven different emotions. A novice or inexperienced observer can overlook micro-expressions because they remain almost undetected by it. By experience and age, people learn to control autonomous facial expressions, movements and gestures by giving away clues about them swiftly.
|Why says I'm afraid?|
Unlike normal or macro expressions, micro expressions appear and disappear within fraction of a second. Sometimes, expressions are miniaturized to keep them unnoticed by observer. Unlike inexperienced or untrained observers, experts can instantaneously crack or zoom into micro expressions. Also, they can be monitored while running video clip at lower frame rate or watching photograph.
Micro expressions can bring surprising turns while interpreting body language because they are emotional outlets of actually what somebody tries to suppress or hide from others. Learned and volunteer control (cortical control) still let their trails appear as much as for 1/4 fraction of a second as per pioneer emotion and facial expressions scientist Prof. Dr. Paul Ekman (University of San Fransisco, United States). He and his colleagues have developed very reliable tool called as Micro Expressions Test Tool (METT) that let you learn and detect micro expressions online. You can test your skills by following this link that takes you to demo test.
|She killed her husband?|
Interrogators and lie detectors mostly rely on micro expressions because smart liars can confidently make claims that ordinary people easily believe. A suspected woman arrested for murder of her husband boldly claims, "I really don't have any idea about him. I hope that he'll come back very soon".
While saying it, she turns contemptuous for fraction of a second. If she really cares about her husband then why she expressed hatred or disrespect? Something must be wrong in their relationship. Expert interrogator can possibly get her confession by asking serious questions.
|No need to check time|
In May 2013, I got a certificate from Humintell for completing facial micro-expression training and passing the final test with 93% percent of accuracy. Though I passed with ‘Expert’ level, it wasn’t an easy task at all because mood of a person at given moment and movements in own facial muscles can make a great difference. However, my own facial muscles helped me to pass the test. Ability to portray micro-expressions on you own face can give you real edge in identifying them on faces of other people.
