#Subtle expression training tool manual
The FACS system is available commercially and the introductory chapters of the manual and investigator’s manual are available online. The idea is that its hard to fully hide emotions as they often quickly or partially emerge on the face before we suppress them, so by being able to detect ‘microexpressions’ we can get a better idea if someone might be trying to hide inner stress. This means the SPOT system is likely to be based on one of Ekman’s two commercial systems for analysing facial expressions: the Facial Actions Coding System ( FACS) or the Micro-Expression / Subtle Expression Training Tool ( METT/SETT).Įkman’s Facial Actions Coding System (FACS), a well-researched method for coding the individual muscle movements or component parts that make up a facial expression. SPOT stands for “Screening Passengers by Observation Techniques” and, according to The New York Times, was created in consultation with psychologist Paul Ekman. Despite the enthusiasm of the authorities for this new approach, there’s no clear evidence that it will be effective.Īmerica’s Transport Security Administration describes the job as involving “voluntary encounters with the public under the SPOT Program, to determine whether elevated behaviors indicate that the individual may be involved in a terrorist or criminal act or activity”. Time magazine is reporting that ‘behaviour detection officers’ have been introduced to US airports who have been trained to pick out potential terrorists by analysing, at least in part, facial expressions.
