Perhaps the most famous theory, the study of body movement, was suggested by
Professor Ray Birdwhistell. He believes that physical appearance is often culturally
programmed. In other words, we learn our looks-we are not born with them. A baby
has generally informed face features. A baby, according to Birdwhistell, learns where
to set the eyebrows by looking at those around-family and friends. This helps explain
why the people of some areas of the United States look so much alike. New Englanders
or Southerners have certain common face features that cannot be explained by genetics
(遗传学). The exact shape of the mouth is not set at birth, it is learned after. In fact,
the final mouth shape is not formed until well after new teeth are set. For many, this can
be well into grown-ups. A husband and wife together for a long time often come to look
alike. We learn our looks from those around us. This is perhaps why in a single country
area where people smile more than those in other areas. In the United States, for example,
the South is the part of the country where the people smile most frequently. In New
England they smile less, and in the western part of New York State still less. Many
southerners find cities such as New York cold and unfriendly, partly because people on
Madison Avenue smile less than people on Peachtree Street in Atlanta, Georgia. People in
largely populated areas also smile and greet each other in public less than people in small
towns do.
