Investigation of Facial Micro-expressions of Emotions in Psychopathy – A Case Study of an Individual in Detention

Abstract: This paper explores the relationship between emotional triggers and various types of (positive / negative) facially displayed emotions by a subject from custody, diagnosed with psychopathy. In this case study, FME were manually measured by using the Facial Action Coding System (FACS, Ekman, Friesen, Hager, 2002), which taxonomies human facial movements by their appearance. The analysis was done frame-by-frame, using a specific pattern to identify the Action Units. Our data allowed for the identification of patterns of the facial movements associated with specific emotional triggers. The same video material will be analyzed by using the automatic FACET system (iMotions).
