text: Finally, in paragraph 9, a study on facial expressions and their relation to emotions is cited. In this study, many important ideas about feelings carried out by humans are stated with truthfulness and security. For example, the Facial Feedback Theory of Emotion states that moving your facial muscles can not only express emotions, but can even help produce them. This states that real emotions can occur from just making a face. Even if the person who was making the expression originally was not feeling that emotion, they may in fact feel that way after one small change in their expression. Also, the author references a "renowed drama coach," Constantin Stanislavsky, who states that he forced his actors to reproduce the actions of smiling and frowning so they genuinely feel happy or sad when on stage. Overall, a change in one small part of your face can change how you feel, and if this technology is implemented into classrooms throughout America, that one small change could alter the way students feel about learning.
