Usage: Though we may show a polite grin or camera smile at will, the zygomatic or heartfelt smile is hard to produce on demand. While the former cue may be consciously manipulated (and is subject to deception), the latter is controlled by emotion. Thus, the zygomatic smile is a more accurate reflection of mood.
Anatomy. Lip corners curl upward through contraction of zygomaticus muscles; crow's-feet show when the zygomaticus muscles are strongly contracted, and/or when orbicularis oculi muscles contract. In the polite (i.e., intentional, weak, or "false") smile, lip corners stretch sideward through contraction of risorius muscles, with little upward curl and no visible crow's-feet.
Evolution. The smile-face may be traced to the primate's grimace or fear grin. The submissive grin, used to show "I am afraid," came to suggest that "I am harmless--and therefore friendly--as well" (Morris 1994). The link between smiling and humor, love, and joy has yet to be explained.
Feedback smile. Smiling itself produces a weak feeling of happiness. The facial feedback hypothesis proposes that ". . . involuntary facial movements provide sufficient peripheral information to drive emotional experience" (Bernstein et al. 2000). According to Davis and Palladino (2000), ". . . feedback from facial expression [e.g., smiling or frowning] affects emotional expression and behavior." In one study, e.g., participants were instructed to hold a pencil in their mouths, either between their lips or between their teeth. The latter, who were able to smile, rated cartoons funnier than did the former, who could not smile (Davis and Palladino 2000).
Media. 1. "So, there's the 1984 study that found that ABC News anchor Peter Jennings was more likely to smile on camera when talking about Ronald Reagan than Walter Mondale, and that in the same year the people who watched ABC News voted for Reagan in greater proportions than the people who watched other network-news shows" (Lacayo 2000:90). 2. "Who has the most coveted smile in Hollywood? 'Twenty years ago, everyone wanted a smile like Farrah Fawcett's,' says Dr. Irving Smigel, a New York dentist who created the Supersmile product line . . . and has worked on Calvin Klein and Johnny Depp. 'Now most of my patients mention Julia Roberts. Her mouth is very feminine'" (Comita 2000:80).
Supermarket mandatory smile. In the late 1990s, Safeway, the second largest supermarket chain in the U.S., instructed its store employees to smile and greet customers with direct eye contact. In 1998, USA Today ("Safeway's Mandatory Smiles Pose Danger, Workers Say") reported that 12 female employees had filed grievances over the chain's smile-and-eye-contact policy, after numerous male customers reportedly had propositioned them for dates. Commenting on the grievances, a Safeway official stated, "We don't see it [the males' sexual overtures] as a direct result of our initiative."
Salesmanship. "You don't have to smile constantly to show you are enjoying yourself. Smile at the peaks" (Delmar 1984:41).
Smiley face. The yellow "smiley face," a popular graphic symbol designed by commercial artist Harvey Ball in the early 1960s, has become a universal sign of happiness. Its color is associated with the brightness of the sun (see COLOR CUE). According to his son, Charlie Ball, Harvey ". . . understood the power of it (the smiley face) and was enormously proud of it [even though others, rather than Ball, profited financially from the design]. He left this world with no apologies and no regrets, happy to have this as his legacy" (Woo 2001:A6). Designed to enhance the Worcester, Mass.-based State Mutual Life Assurance company's "friendship campaign," to bolster employee morale, the smiley face took Ball about 10 minutes to complete (Woo 2001). "Fearing that a grumpy employee would turn the smile upside down into a frown, he [Ball] added the eyes" (Woo 2001:A6; see ISOTYPE).
