text: School behavior is a big part of a students education. If a student is constantly acting out and misbehaving it could affect his or her education pretty badly. Although, that is why Facial Action Coding Systems could also be very useful in a classroom environment. The technology could be able to detect if a student is being dishonest, which could prove very handy when dealing with situations with delinquents and trouble-makers. In the excerpt, the author writes, "To an expert, faces don't lie; these muscle clues are sometimes used to spot when a "smiling politician or celebrity isn't being truthful," (D'Alto). In this quote, the author tells the reader about some facial muscle clues that allow experts to tell if a famous figure is being dishonest. These are some of the same facial clues the FACS looks for.
