Think about the way we communicate with each other by means of facial expressions. One way is to mimic the other person's expression and so induce the feeling that corresponds with the expression. Another way is to 'read' the expression, as though it were a text. People with Moebius Syndrome cannot create facial expressions, so they cannot induce feelings, but must instead read faces and decrypt the expressions. Does it work? According to this study (quick read, worth the ten minutes), it does. But is it necessary, and do most people do it this way? It's not clear. Interesting, and related to my transmission versus induction discussion from the weekend.
