If you are interested in hiring someone, first make sure they are FACS certified i. You would also want to be sure they have had coding experience beyond testing — as the Final test simply tells us that someone is proficient in recognizing the AUs, and coding real life data reliably takes practice.
To do this, the coder scans the video for core combinations of events that have been found to suggest certain emotions much like the prototypes in Table The coders only codes the events in a video record that contains such core combinations — they use FACS coding to score those events, but they are not coding everything on the video.
The drawback is that it can be harder to get intercoder agreement on EMFACS coding as the coders have to agree on two things: 1 whether to code an event a result of their online scanning of the video for the core combinations and 2 how to code those events that they have chosen to code.
Only people who know FACS as a comprehensive system can correctly apply it on a selective basis. There are also some situations in which social norms force people to conceal, mask, or inhibit true feelings in ways depending on politeness, context, culture or their status Ekman, Fortunately, the suppressed expressions can be expressed subconsciously in the form of microexpressions and therefore can be detected by a skilled observer Ekman and Friesen, ; Ekman, It expresses one of the six universal emotions: disgust, anger, fear, sadness, happiness, and surprise.
This kind of facial expression usually occurs in high stake situations, where people have something valuable to gain or lose Ekman et al. According to Ekman et al. A microexpression, therefore, can be an essential behavioral clue for lie detection and can be employed as a means of detecting a dangerous demeanor Metzinger, ; Schubert, ; Weinberger, Some extreme actions like terrorist attacks around the world necessitate the use of various technologies to detect dangerous individuals and prevent such actions.
Analysis of microexpressions was found to be a suitable approach Weinberger, Although few peer-reviewed studies about microexpressions have been published Porter and ten Brinke, ; Vrij et al.
A microexpression and a macroexpression differ only in their duration Ekman and Friesen, ; Ekman, Thus, there is a lack of consensus about the time range of the duration of a microexpression.
The difference in duration might not be large, but for a fleeting thing like a microexpression, the difference should be taken into account.
Therefore, the appropriate upper and lower limits of duration of microexpressions should be clarified. For this purpose, we can ask participants in a study to distinguish between microexpressions and macroexpressions, which differ only in terms of duration the former are short; the latter are long.
Supposing that the accuracy of recognizing a microexpression is equal to that of recognizing a macroexpression of longer duration, for the participants there should be no difference between microexpressions and macroexpressions even when they are of different durations for example, they may think that 1 s happiness is the same as 3 s happiness.
Then why bother to use a different name for the same thing i. We can use the duration at and beyond which the accuracy of recognition of a microexpression is not significantly different from that of a macroexpression as the critical time point to distinguish a microexpression from a macroexpression, and this duration can be regarded as a proper upper limit of duration of microexpressions.
Based on the hypothesis of level of processing Craik and Lockhart, , we can say that the longer is the duration of expression, the deeper is the processing, and therefore the higher is the accuracy of recognition. Thus, according to this hypothesis and the analysis above, for microexpressions of different durations, there should be a turning point after which there will be no significant difference between the recognition accuracy of a microexpression and a macroexpression where the level of processing for a microexpression is not different from that of a macroexpression.
Thus, after that time point, there will be a plateau phase of recognition accuracy in which it would be meaningless to differentiate microexpressions from macroexpressions.
Therefore, we take this point as an upper limit for microexpressions. Subscriber Login Email Address.
