The studies of Paul Ekman, a psychologist who created the Facial Action Coding System (FACS), indicates that a lot of "thin slicing" can be done within seconds by unconsciously analyzing a person's fleeting look called a microexpression.
Furthermore, a cross-species analysis of facial expressions can help to answer interesting questions, such as which emotions are uniquely human. [21] The Emotional Facial Action Coding System (EMFACS) [22] and the Facial Action Coding System Affect Interpretation Dictionary (FACSAID) [23] consider only emotion-related facial actions.
