The purpose of facial expressions

Do facial expressions reflect inner feelings? Or are they social devices for influencing others?

A
AThe use of facial expressions for measuring people's emotions has dominated psychology since the late 1960s. This was when Paul Ekman of the University of California pioneered the idea that, by carefully measuring facial expression, he could evaluate people's true emotions. Ekman carried out experiments in which people were asked to label photos of basic facial expressions such as a smile, frown or scowl with words for emotions. He found, for example, that a smile represented joy and a scowl represented anger. In fact, since the 1970s Ekman has dominated the field of emotion research with his theory that when an emotion occurs, a large number of electrical impulses also occur, creating specific facial expressions and other physiological changes, such as increased or decreased heart rate or heightened blood pressure.

BMany took Ekman's work to imply that facial expressions precisely indicated people's feelings. However, this theory has been attacked by a number of psychologists, such as Alan Fridlund of the University of California, who claim that there is no one-to-one correspondence between facial expressions and emotions. Expressions evolved to set off certain behaviors in other people, says Fridlund. So a smile may prompt people to approach, a scowl may warn them to stay away, and a look of sadness may elicit words of sympathy and reassurance. In other words, in Fridlund's view, facial expressions are inherently social they involve not one, but two or more people. Even when people are alone they are holding a dialog with another person internally, or imagining themselves in a social situation.

CThus Fridlund thinks of facial expressions as tools for influencing social interactions, a view which, he claims, enables us to begin predicting when certain facial expressions will occur. This in turn will allow more precise theories about social interactions. His studies find that expressions occur most often during pivotal points, the turning points in social interactions during greetings, social crises, or times of appeasement, for example. At these pivotal points there is an approach, or closeness, or more intimacy, and facial expressions, as well as gestures, open up the possibilities of various social interactions.

DAlthough much work on the emotions relies on a link between facial expression and emotions, psychologist James Russell, of the University of British Columbia, says there is very little evidence supporting such a connection. 'There's some sense in which faces express emotion, but only in the sense that everything expresses emotion,' says Russell, a long-time critic of the expression-emotion link. 'Music does, posture does, words do, tone of voice does, your behavior does. The real question is, "Is there anything special about faces?"" And there we really do not know much. What is more likely, argues Russell, is that facial expressions tell others something about a person's overall mood and context, rather than provide details about specific emotions.
E
EOthers, including Ekman, argue that the face can display information about emotions, but they admit that it is not reliable one hundred percent of the time. And those who only examine faces when trying to study emotion will jump to false conclusions. But according to Ekman, to say, as Fridlund does, that there is no connection at all between facial expressions and emotions is simply wrong. 'There is a link between facial expression and emotion,' agrees developmental psychologist Linda Camras of DePaul University, 'but it's not a one-to-one kind of relationship as many once thought.' She believes there are many situations where emotion is experienced, yet no basic facial expression is displayed. And there are times when a facial expression appears with no corresponding emotion.
F
FEkman's theory states that if the emotion comes on slowly or is rather weak, the feeling might not be strong enough to trigger the expression. This would explain why there can sometimes be emotion without expression, he argues. In addition, cultural rules which determine when and whether people of certain cultures display emotional expressions can prevent this otherwise automatic process from being completed. Facial expressions evolved in humans as signals to others about how they feel, says Ekman. At times, though, it may be uncomfortable or inconvenient for us to let others know our emotions. But in the long run, over the course of evolution, it was useful to us as signalers: an angry look on someone's face may be a warning that they are preparing to behave in an angry fashion.
G
GAlthough Fridlund disagrees with Ekman on certain matters, the two basically share the opinion that facial expressions indicate people's future actions. The area of dispute between Fridlund and Ekman draws attention away from their major areas of agreement, says Joseph Campos of the University of California. Indeed, he says, 'there is profound agreement that the face, along with the voice, body posture and hand gestures, forecasts to outside observers what people will do next.' He goes on to say, 'The face is a component [of emotion], but to make it the center of study of the human being experiencing an emotion is like saying the only thing you need to study in a car is the transmission. Not that the transmission is unimportant, but it's only part of an entire system.'
